2, Real product description, not false marking wattage

There are some solar street lights labeled 1000 watts,1000 watts!!!  Do you believe it? I don’t believe it!
Solar street light has true luminous flux, solar panel, and battery capacity. These are very important information. It would be nice if it could tell us how many hours it can operate based on a full output of lumens.

I know this can be calculated based on its capacity, voltage, and current, but how? It’s too hard for the end user!

3 . Very good waterproof performance

Many solar street lights have very poor waterproof ability, no rubber ring, and no glue, which greatly affects the life of solar street lights. But the Solar Street Light with Five-Star Review
The solar panel is located between the luminaire and the housing and fixed with glue, very safe. On the other side, the transparent PC cover is located, between the luminaire, and the housing, which is also filled with silicone. It has a very good waterproof function.

4. Better quality and materials

First: Solar street light Battery type

A-class LiFePO4 Lithium> B-class LiFePO4 Lithium>Ternary Li-ion Lithium> Broken Lithium detached from the electric car(D-class), over 90% of Solar street light manufacturers use broken lithium battery which is detached from Electricity car, lifespan less than one year.

If you want to buy high-quality solar street lights, Belinda suggests you choose an A-class A-class LiFePO4 battery or a B-class Lifepo4 battery, Although their cost is higher than other batteries, their lifespan will be extended by more than three to five years. if you need to install solar street lights in places where the sun is not particularly sufficient, we can also choose to use a Ternary lithium battery.

Second: Solar street light Solar panel size Case and Bracket Material

Quality solar street lights use a customized die-casting aluminum mold, The advantages of die-casting aluminum mold are lightweight, strong corrosion-resistant, and anti-rust. Making it able to resist a strong wind load of up to 130MPH, stainless steel screws are used as fasteners to protect against any harsh weather. The die-casting aluminum mold is elegant and characteristic.

Lower quality solar street lights just use mold and rough craft, the installing structure needs support by Knighthead, to recover the structure strength issue, making installation more complex, lack of stability, and not anti-strong wind.

Conclusion:

In recent years, many customers often complained that the solar street lights they bought do not work properly or do not work even in less than six months. Because some suppliers are looking for quick profits in a hurry but do not pay attention to the quality standard of their brand products. A very good quality solar street light can last more than 5-8 years.

Solar street lights systems are project products, usually, a project needs dozens to thousands of sets of solar street lights, if you accidentally choose a low-quality solar street light, you will suffer huge losses, so I recommend customers choose carefully, do not just focus on low-cost products, and I hope that my summary of choose quality solar street light experience can give you some help.

    Split Solar Street Light VS. Integrated Lights?

    Split Solar Street Light VS. Integrated Lights?

    Solar street lights have 2 types, split solar street lights, and integrated solar street lights, The main differences are the component parts, price, installation complexity, technical parameters, scope of application, maintenance, etc, there are no absolute advantages and disadvantages, according to the use of occasions, we can choose according to the use of the occasion.

    Let’s Learn more about the difference between integrated and split solar street lights as below.

    What are the differences between integrated and split solar street lights?

    1, Components different

    Split solar street light consists of the battery, LED lamp head, photovoltaic panel, controller, and lamp post, and must be equipped with a lamp post, the battery should be buried in the ground, through the lamp post wire connection. Integrated solar street light integrated with the battery, LED lamp head, controller, and solar panels together to the lamp head inside.

    2, Different price

    Due to design reasons, integrated solar street light panel power and battery capacity are generally less than the split type, so the cost is lower, so the same specifications, integrated solar street lights than the split type street light are much cheaper.

    3, Installation of different

    The integrated solar street light installation is more convenient and easy, usually within 5-15 minutes. while the split solar street light needs to be assembled, threading and wiring, installing the battery bracket, light head, making battery pit, etc., relatively complex.

    4, Application different

    Split solar street light has a wider scope of application and can be used in wider roads and highways, squares, districts, industrial parks, etc. The integrated solar street light is usually used in urban roads, streets, alleys, districts, factories, industrial parks, and rural roads.

    5、Maintenance Different

    When the solar street light does not work, split solar street light manufacturers need to send the technicians to the local maintenance, checking with the battery, photovoltaic panels, LED lamp head, wires, etc. one by one to solve the problem; integrated solar street lamps just need to unload the lamp head and send it back to the factory directly or instead of the battery or controller by yourself.

    Split Solar Street Light VS. Integrated Lights?

    Choose all-in-one solar lamps VS. split lamps.

    Maybe it is hard to decide whether to choose all-in-one solar lamps or split lamps, today, we will conclude why to choose all-in-one solar street lights rather than split lamps.

    After analyzing the sales data, we have found out that clients prefer to integrate into one solar street light instead of a split or semi-split type solar light. Customers are more likely to purchase integrated solar street LED lights, even if most of them have purchased split-type lights before.

    The research data can help you know the market trends to choose a better type of solar street light for your future project or invest in your business.

    Following are the 3 reasons why choose All in one solar street light

    (1): Integrated solar street light installation is straightforward and saves time

    Integrated all-in-one solar lamp installation is very simple and quick. It only takes 5 minutes for skilled workers to complete all of the installation processes. If you have a large solar street light project, and split solar street light requires a gel battery pit, and gel batteries are hanging on sole light poles. This complicated installation method is a big problem when the construction project deadline is rushed.

    Integrated all-in-one solar street lights can reduce installation errors, fast construction speed, and save labor costs, which is a comparative advantage to split-type solar lamps.

    (2): The total cost of integrated solar streetlights is low

    The total cost involves two parts. one is the cost of labor. From the analysis of the above, we know that the longer the installation time, the higher the labor costs. So the contractor will tend to choose a lower-cost way.

    Another part of the cost relates to solar street light batteries. The gel battery for split-type solar outdoor lights is bulky and Polluted by the environment, not clean energy.

    For example, 100W split street lights need to use 180AH batteries, which must match with 330W solar panels, while 100W all-in-one solar street lights just need to use a 39Ah LiFepo4 battery and 140W solar panel.

    We can clearly see that the same wattage of solar panels used for integrated solar-based lights is at half price compared to split type.

    (3) Integrated solar streetlights are more intelligent

    Integrated solar lamps generally use intelligent MPPT controllers. Based on big data analysis and human flow judgment, the controller may adopt the modes of time control and/or human induction mode intelligently. When people are close to the light, the light is full power 100% and when there is no movement, the light power can adjust to 30% automatically. But for split-type solar street lights, 100% luminance output configuration, almost half of the night is a waste.

    Conclusion:

    In summary, integrated solar streetlights are becoming more and more popular, and will become a trend in the future. Compared with split solar street lights, they are more worthy of investment.

     

    Lifespan of solar street light

    How long is the lifespan of solar street lights?

    The Lifespan of a solar street light mainly depends on its accessories, including solar panels, controllers, batteries, and light sources, the shortest is the battery, the service life of lithium batteries used now is more than 5 years, and the general life of the solar street lamps are 5 to 8 years. Still, the replacement of batteries can continue to be used.

    To extend the life of solar streetlights, the key is the accessories. Below is the information on how long the life of solar street lights is and how to extend the life of solar street lights.

    Related article: https://www.Clodesun.com/why-people-dont-trust-chinas-solar-street-lights-now/

    How long is the life of solar street lights

    Generally speaking, the life of a solar street light is related to its accessories, the accessories of solar street light are mainly composed of solar panels, controllers, batteries, light sources, and poles, and the service life of different accessories will be different.

    1. solar panels, ‘ service life is more than 20 years, and after 20 years the solar panels will only have a certain degree of light degradation (about 30 percent or more), but they can continue to be used.

    2. Controller, the general service life is about 8 to 10 years, depending on the electronic components and the use of the environment.

    3. Battery, solar street lamps have generally used lead-acid gel batteries in the past, the service life of such batteries is about 3 years, generally fast approaching the age of the lead-acid batteries may be aging very seriously, the capacity of even the base of the 10% are not up to the basic, basically can not meet the demand for bright lights.

    Now most batteries use lithium batteries, lithium batteries, have high and low-temperature resistance attributes than lead-acid batteries, a number of cycles than lead-acid batteries than colloidal batteries, and a depth of discharge can reach more than 2,000 times, so the service life of lithium batteries can have more than 5 years.

    4, Light source, solar street lamps are used in the LED light source, and good LED light source life can reach more than 11 years.

    5, Light poles, the service life is relatively long, if the use of hot-dip galvanized and do a good job of anti-rust measures, life expectancy can be more than 20 years.

    To sum up, the main factor restricting the life of solar street lamps is the battery, under normal circumstances, the general life of solar street lamps is 5 to 8 years, but most of the accessories are able to be used normally and only need to replace the battery.

    How to extend the service life of solar street lights

    Solar energy is a kind of green renewable energy, now many places use solar street lights. But the lifespan of solar street lights is limited, to extend its life, the main attention to the following points:

    1, Choose high-quality solar panels

    The main function of solar panels is to collect light and convert light energy into electricity, regular manufacturers of solar panels have longer life, so we should pay attention to buying quality assurance products.

    2, Choose a good heat-dissipation light source

    Solar streetlights need to dissipate heat in two locations, one is the head, and the second is the battery. Solar street lamps are generally selected LED lamp heads, we should buy good heat dissipation function lamps, so as to be able to extend the service life of LED lamp beads.

    3、Select high-quality battery

    The battery is the strong backing of the solar street light, if the battery life is not long, then the service life of the solar street light will not be very long. Generally speaking, the best heat dissipation effect is the kind of A-grade LiFePO4 with an aluminium-magnesium alloy shell, long life, fast heat dissipation, and quality assurance.

    4, choose the right solar street light controller

    The solar street light controller is the central nervous system in the solar lighting system, responsible for coordinating the work of solar panels, lithium batteries, and loads. It is a key component of the solar street light lighting system, we must not be greedy for cheap choice of cheap controllers, it is recommended to choose a reputable manufacturer and buy a qualified controller.

    5、Light pole types

    Solar street lights mainly rely on the pole to support, the service life of the street light pole depends entirely on what kind of galvanized, cold galvanized pole will appear after 1-2 months of outdoor use rust, long-term use will have certain safety hazards; good solar street light pole is hot dip galvanized, the service life of up to 20 years.

    Conclusion:

    In recent years, many customers often complain that the solar street lights they bought do not work properly or do not work even in less than six months. Because some suppliers are looking for quick profits in a hurry but do not pay attention to the quality standard of their brand products. A very good quality solar street light can last more than 5-8 years.

    Solar street lights systems are project products, usually, a project needs dozens to thousands of sets of solar street lights, if you accidentally choose a low-quality solar street light, you will suffer huge losses, so I recommend customers choose carefully, do not just focus on low-cost products, and I hope that my summary of choose quality solar street light experience can give you some help.

    Lithium Iron Phosphate (LiFePO4) batteries are another great lithium battery technology but for a lower price. LiFePO4 batteries are manufactured with graphite anodes and lithium iron phosphate cathodes, immersed in a lithium salt electrolyte. This is the preferred lithium technology for solar street lights since it is cheaper than Li-Ion but still provides a maintenance-free option with high energy density. Relate article:2022 Best Battery for Solar Street Light

    Which solar street light battery type is the best?

    clodesun solar street light battery

    While knowing about the different aspects to consider when choosing a battery. Nowadays, Solar Street Lights batteries prefer to use Lithium Iron Phosphate batteries (LiFePO4) and good quality batteries compared to Lithium-ion batteries. Lithium Iron batteries can be cyclically charged and discharged more than 2000 times, with long life, high safety performance, and strong resistance to low and high temperatures. On the basis of our selection of lithium batteries, the use of intelligent balancing technology and intelligent dual protection technology to make the battery life longer. But there are currently 4 grades of LiFePo4 batteries on the market, A-class LiFePo4 battery, B-class LiFePo4 battery, li-ion battery, and D-class LifePo4 battery(Already eliminated used LifePo4 battery).

    1.A- class LifePo4 batteries(about 4$/AH 8-10 years life span)

    A- Class LifePo4 battery refers to the battery capacity, thickness, length, width, and other parameters. The battery manufactured in accordance with the standard is called A class, and the solar street light life span can last 8-10 years.

    2. B- class LifePo4 batteries. (about 2.7$/Ah-3$/Ah 5-8 years lie span)

    refers to a slight gap in battery capacity, or the length, width, and thickness do not meet the order requirements, and the price is cheaper than product A. In addition, product A is generally placed in the warehouse. If it has not been shipped for 3-6 months, it is also called B class, the solar street light life span can last 5-8 years.

    3.C- class LifePo4 batteries.(1$/Ah-1.5$/AH 1-3 years life span)

    C-class LifePo4 batteries are indeed saying that the battery of product B has been placed in the warehouse for more than 8 months. If it has not been shipped, it can be called product C. The battery of product C is due to the long storage time. With the self-discharge and dust, water For the aging of gas, the performance of the C-type cell is generally only about 50-60% of the A-type cell of the same model. The safety of the C-type battery is poor. In addition, the C-type battery is not durable. After several cycles of charging, the performance is greatly reduced. the solar street light life span can last 1-3 years.

    4.D-class LifePo4 battery(0.5$/Ah-0,8$/Ah 0.6 months-1year life span)

    D-class LifePo4 battery(Already eliminated Or have been used LifePo4 battery also called a second-hand battery), Capacity, pressure drop, internal resistance, circulation, and other performance are in a very low and unstable state, not only can not meet the assembly requirements, but its service life is usually 6-8 months, you need to replace the battery, which is also the most popular Battery on the market. the solar street light life span can last 0.6-1 year.

    And where did these eliminated LifePo4 batteries go? For what use? It is understood that many eliminated LifePo4 batteries have just flowed into the solar street light industry, Unfortunately, more than 90% of solar street light manufacturers on the market now use this LifePo4 battery that has been eliminated which causes another disadvantage to the solar street light market that already lacks standards. The industry is more uneven, and the gap between prices and quality is greater.

    A-class LiFePO4 Lithium> B-class LiFePO4 Lithium>Ternary Li-ion Lithium> Broken Lithium detached from the electric car(D-class), over 80% of Solar street light, manufacturers use broken lithium battery which is detached from Electricity car, lifespan less than one year.

    2. Solar street light pole price

    How many types of Solar street light poles?

    Solar street light pole type materials are different, there are galvanized, aluminum, straight square steel, round poles, tapered poles, ornamental poles, synthetic composite fiberglass, or concrete poles/posts. If you are looking for the best anti-rust pole, a hot-dip galvanizing pole is the best option. The product claims that it will not rust in 8-10 years. Among other pole types, a hot-dip galvanizing pole is the most expensive. Another option is the cold-dip galvanizing pole with an average anti-rust effect lasting 2-3 years. When buying a solar street light pole, we also need to consider its hurricane-resistant poles – solar lighting poles need very sturdy that they can withstand wind speeds of up to 175 miles per hour. This ensures that solar street lighting systems will still be up and running after the storm has passed; offering safety and security when you need it most.

    Which solar street light pole type is the best?

    Among the three solar street light poles mentioned above, we recommend that customers choose hot-dip galvanized light poles. Although the price is more expensive, it has a good anti-rust effect and hurricane resistance and will last longer. There is a kind of galvanized pipe paint, which usually rusts in half a year to a year. Just be careful in purchasing as many cold galvanizing on the market are now pretending to be hot galvanized.

    How much does a solar street light pole cost?

    Solar streetlights come with a wide variety of pole sizes which affects the cost. Below are some of the types of pole-height designs for solar streetlights design:

    3m-4m about (15$/m-20$/m) hot-dip galvanized light Cone straight poles price is about(45$-80$), The thickness of lamp pole is 2.5mm, pole to pole distance is 15-20m, with a 30w-40w solar street light.

    5m-6m about (15$/m-20$/m) hot-dip galvanized light Cone straight poles price is about (75$-120$), The thickness of lamp pole is 2.75mm pole to pole distance is 20-25m, with 50w-60w solar street light.

    7m-8m about (17$/m-22$/m)hot-dip galvanized light Cone straight poles price is about (119$-176$), The thickness of lamp pole is 3mm, pole to pole distance is 25-30m, with an 80w-100W solar street light.

    9m-12m about (19$/m-25$/m)hot-dip galvanized light Cone straight poles price is about (171$-300$), The thickness of lamp pole is 3.25mm, pole to pole distance 30-35m, with a 120W-150w solar street light.

    3. Solar street light LED Chip price

    5. Solar street light solar panel price

    No alt text provided for this image
    solar panel street light

    There are 3 types of solar panels used in solar streetlights

    High-efficiency Monocrystalline Double-sided Solar Panel (about 0.4$/W)

    High-efficiency Monocrystalline(about 0.33$/W-0.37$/W)

    High-efficiency Polycrystalline(about 0.30$/W-0.32$/W)

    Why do we choose a Monocrystalline solar panel or a High-efficiency Monocrystalline Double-sided Solar Panel? By selecting a monocrystalline solar module, Solar-led Street Lighting International knows it will produce more energy, work better in high temperatures, and last longer than a polycrystalline panel.

    The wider solar panel size means Large load power, and high capacity, which can increase the solar panel Efficiency, could offer enough power for bearing power, and is the insurance of brightness and longer backup time during cloudy days.

    However, the low-quality solar panel size configuration is less than two and a half times the load power. If the cloudy days exceed more than the expected design requirements, the LED light would not work.

    6. Solar street light Case and Bracket Material price

    Quality solar street lights Case and Bracket Material(about 60-100$) use a customized die-casting aluminum mold due to its abundant benefits. The major advantages of die-casting aluminum mold are lightweight, strong, corrosion-resistant, and anti-rust. With its solid and firm materials, it can withstand a strong wind load of up to 130 MPH. It is also equipped with stainless steel screws that are used as fasteners to protect against any harsh weather conditions. Aside from that, the die-casting aluminum mold looks elegant and classy.

    On the contrary, lower-quality solar streetlight cases and Bracket Materials(about $ 30-40) just use mold and rough craft. Usually, the installation requires the support of the knighthead, to recover the structure strength issue, making the installation more complex. It also lacks stability and cannot withstand strong wind.

    7.  Solar street lights Warranty time

    Usually, solar streetlights have a 2-year, 3-year, and 5-year warranty. The ultimate tip is to get the solar street lights with a longer warranty period as these street lights are usually equipped with better materials. On the other hand, solar street lights with a 2-year warranty are generally cheaper and suitable for rural roads or household use. Whereas, the 3-year warranty is 20% cheaper than the five-year warranty. But if you will install a solar street light in a place with high demand for light conditions, we recommend buying one with a five-year warranty for better materials.

    Conclusion

    Could you mind me asking you a few questions?

    Do you dare to use the 0.2 USD/piece mask?

    Do you dare to eat $0.8/kg beef?

    Or will you use the $300/piece iPhone 13 Pro?

    Your answer should be no, but why do very cheap solar street lights dare to use them? Just because a few examples above may threaten your life. But the quality of solar street lights is not a threat to the safety of your life but it will threaten your reputation and the honor of your business, Maybe you can understand what I said.

    I have been working in the solar street light industry for many years, the most frequently asked question is, How much do solar street lights cost? But before we answer that question, let’s break down first some of the major factors influencing solar street light prices.

    Solar street light costs are highly influenced by several factors. Therefore, you should take note of these factors to understand the pricing. Compared to conventional street lights, solar street lights are essentially more cost-effective, energy-saving, and environmentally friendly. While the upfront cost of solar street lights is more expensive than the cost of traditional street lights,

    Solar streetlight prices are influenced by many factors. solar street lights with poles and batteries are the 2 most important factors in understanding the pricing. When you are looking for a battery and pole for solar street lights, consider the aspects talked about during the article, which will help you choose a suitable, high-quality solar street light to avoid losses.

    We recommend purchasing solar street lights from reputable manufacturers only because they provide good biggest deals and high-quality solar street lights. Aside from that, they often offer discounted rates for bulk orders.

      Top 5 Countries for Solar Street Lighting Installations

      As we all know, solar street lights are suitable for installation in places with very good sunlight.

      There are three most suitable districts to install solar streetlights

      1. Southeast Asia

      Southeast Asia is always a hot spot for the application of solar energy due to its tropical location and sufficient sunshine all year round.

      2. African

      On average, African countries can receive strong sunshine in 325 days per year with a covering rate of 60,000,000/hour per day per square meter. Theoretical reserves of solar energies account for nearly 40% of the total global reserves. However, this region produces only 1% of the world’s photovoltaic power, the electricity popularity rate for most countries is less than 50%, and there is no lighting on most non-trunk roads at night. Solar street light products can make good use of the advantage of sufficient local sunshine and transform it into electricity for roadway lighting.

      3. Middle Eastern

      The climate in the Middle Eastern region is dry and hot and lacks rainfall throughout the year, thus it satisfies installation conditions of solar street lights.

      Solar street light projects

      There are Top 5 Countries for Solar Street Lighting Installations

      1. Philippines Solar Street Light Overview

      • Philippine government policy support Integrated solar street light in the Philippines

      The Philippines is a rapidly growing nation in Southeast Asia, and this rise in population growth means that the demand for power is also rapidly rising. With traditional fossil fuels negatively affecting our environment, the Philippine government has to look for sustainable ways to generate energy. And fortunately, one renewable energy source that they have taken notice of is solar energy.

      When it comes to solar development, the Philippines is still relatively young. Still, with its wealth in sunlight, it is only a matter of time before the country has caught up with recent developments in solar technology.

      Moreover, the Philippines has the highest electricity costs in Asia, tied with Japan, so it only makes sense that the country utilizes solar power because it is a much cheaper and more economically advantageous choice. With solar power, electric bill costs will fall in the country, and at the same time, people who are currently off the grid will have access to an electricity source.

      • Rich solar resources are good for integrated solar street light in the Philippines

      The country’s geographic location is a good enough reason for the Philippines to implement solar power. A tropical country, the Philippines receives a lot of sunlight. To be more specific, the National Renewable Energy Laboratory conducted a study that revealed that the Philippines has an average solar energy potential of 4.5kWh/m2 per day.

         2. Malaysia Solar Street Light Overview

      When the global call from scientists urged nations all over the world to shift from burning fossil fuels to using renewable energy for energy production, Malaysia was one of the nations that decided to take action. After all, Malaysia receives a lot of sunlight due to its equatorial location, so the country has a strong potential to use solar energy.

      However, despite the country’s promising potential to establish several large-scale solar projects, solar development in Malaysia is still in its infancy stage. This is primarily because of the high cost of PV cells, solar electricity tariff rate, and lack of funding.

      But on the bright side, Malaysia’s renewable energy development is growing. Currently, 8% of the country’s energy is from renewable sources, and the government has pledged to increase that percentage to 20% by 2025.

      • Why Solar Energy Is a Good Choice for Malaysia

      Malaysia is a tropical country located in the equatorial region, so this country enjoys an abundance of sunlight. In particular, the country’s average solar radiation ranges between 4.7–6.5kWh/m2. For this reason, Malaysia is a strong contender for using solar energy as its primary source of power.

      Furthermore, just like other developing countries, Malaysia faces the problem of a rapid rise in energy consumption due to an increasing population. And since fossil fuels are not renewable, nor are they healthy for both the environment and people, the government has to seek an alternative quickly. Solar energy is the best option for them.

       3. Nigeria Solar Street Light Overview

      Nigeria is among the most dominant countries in Africa, and it is also a country blessed with a high amount of sunlight. Because of this, Nigeria has a great potential to utilize solar power to its advantage, thus possibly leading to billions of dollars saved and millions of households electrified.

      Fortunately, the Nigerian government has recognized the country’s potential for solar power, and though the country severely lacks renewable energy production, the government has decided to focus on creating its own solar power infrastructures.

      • Why Solar Energy Is a Good Choice for Nigeria

      As stated earlier, Nigeria is a country that receives a lot of sunlight, so it is only logical that the government would use this renewable source to its fullest potential. But in addition to that, Nigeria suffers from unreliable electricity, and solar energy can help solve that problem.

      To elaborate further, a report in 2015 declared that around 55% of Nigeria’s 190 million citizens have no access to grid-connected electricity. But even those that do have access to centralized power still suffer from power cuts and outages.

      This unreliable power supply costs Nigeria so much money, around $29 billion per year, thus causing the country’s economic growth to falter. The unreliable electricity also forces Nigerians to rely on generators that run on fossil fuels, which are detrimental to one’s health.

      However, if the Nigerian government uses the abundant solar energy that the country has and creates a solar-powered energy production system, things would improve drastically. Millions of households would receive electricity from a reliable and renewable source, and billions of dollars could be saved.

      • Notable Solar Projects in Nigeria

      Nigeria has undergone several solar projects throughout the years, with varying degrees of success and popularity.

      The first notable project is the proposed “Energy for All” plan. This plan aims to provide solar panels to five million households that are not connected to the grid, which means that the target is the rural population since urban areas have access to electricity. As a result, this plan has the potential to decrease rural poverty in the country, and hopefully, it will exponentially cut down the use of biofuels and other non-renewable energy.

      Another popular solar project in the country is the Solar PV Project. Financed by B&S Power (a Singapore-based renewable energy corporation) and Sunnyfield Global (a Nigerian investment entity), the Solar PV Project is a 200MW solar project located on about 304 hectares of land in Ashama Village.

      Aside from these big projects, there are other small solar projects. A few examples include solar water heaters, solar cookers, and solar chicken brooders.

       4. South Africa Solar Street Light Overview

      The entire continent of Africa is home to a wide variety of natural resources, and South Africa, in particular, is excessively rich in solar power. As a result, there is so much potential for South Africa to use solar energy to its fullest potential, and luckily, the government has acted relatively quickly on this possibility.

      The South African government implemented an energy policy named The South African Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) that aims to seek alternative energy sources in an effort to combat climate change and save money. They have also already made a plan to develop energy generation infrastructures for 2010 to 2030, aiming to reach 9600MW of solar power capacity by the end of 2030.

      • Why Solar Energy Is a Good Choice for South Africa

      Throughout the years, the costs of solar energy have started to steadily decline, and currently, they are now affordable. As a result, switching to solar power is a highly recommended option, and this is especially true for South Africa since this nation receives a lot of sunlight and solar radiation. To be more specific, the average number of hours of sunlight in South Africa is 2,500 hours a year, and its average solar radiation levels are between 4.5 and 6.5kWh/m2 per day.

      Because of all this, once South Africa moves from fossil fuels to solar energy for energy generation, the country can help impede climate change and save a ton of money in the process as well.

       5. United Arab Emirates Solar Street Light Overview

      The United Arab Emirates (U.A.E.) is one of the major oil producers in the world, just like its neighboring country Saudi Arabia. U.A.E. had also ranked one of the top carbon dioxide emitters per capita in the world. However, even though this is the case, the U.A.E. government has taken steps to shift to renewable energy, especially solar power.

      Solar power still accounts for a small percentage of the entire energy production in the country. But the government is aiming to generate about 50% of its electrical energy from renewable sources by 2050.

      Currently, they are doing well with this goal, and there is even a possibility that the country’s solar capacity will increase fourfold by 2025, raising the current 2.1GW capacity to 8.5GW.

      • Why Solar Energy Is a Good Choice for U.A.E.

      The U.A.E. holds the title of one of the highest solar exposure rates in the world, so the country is undeniably suitable for producing solar energy.

      Aside from this, using renewable energy sources can help save money for the country as well. To be specific, if the U.A.E. would avoid the consumption of fossil fuels and ramp up the usage of renewable energy, the country could save about $1.9 billion every year by 2030.

      Last but not least, the prices of solar technology have rapidly declined, while the prices of natural gas have risen. This makes solar energy a competitive option for power generation in the country.

      • Solar Projects in U.A.E.

      U.A.E. is now constructing a solar power project that will be the world’s biggest one so far. Called the Al Dhafra Solar PV facility, this project has a solar capacity of 2GW, and it will supply power to Emirates Water and Electricity Company (EWEC).

      In addition to this project, U.A.E. also has the world’s concentrated solar power plant. Located in western Abu Dhabi, this CSP power plant was launched in March 2013, and it can power about 20,000 homes.

      Mohammed bin Rashid Al Maktoum Solar Park is another notable solar project. This solar park can generate 1,000MW by 2020 and 5,000MW by 2030.

      U.A.E. has more plans to fund and develop several PV and CSP projects.

      Conclusion

      So far, Clodesun Solar Stree Lighting has undertaken the Kenya project and Yemen project of the United Nations Office for Project Services, the Syria project of the United Nations Development Program, the international Cameroon Project, as well as national projects of Benin, Malaysia, Philippines, Thailand, etc.;

      We have accumulated experience in hundreds of domestic and overseas large-scale roadway lighting projects, creating feasible technology space for product innovation and upgrading.

      As the prospects for integrated solar street lights in the Philippines become better. Since 2017, the government has begun large-scale support for solar energy development. The Philippines has become the second-largest integrated solar street light market. Clodesun plans to build a warehouse and supply new designs in the Philippines.

       

       

       

       

      SOlar street light battery

      4 Types of Batteries for solar street light?

      The battery capacity directly affects the performance and functionality of solar streetlights. A battery with a larger capacity can power brighter LED lights, cover a wider area, and provide enhanced lighting intensity. This results in improved visibility, increased safety, and better security in the illuminated areas. Consequently, solar street lights with higher battery capacities offer superior performance, but their advanced capabilities contribute to their higher prices

      Best Rechargeable Batteries for Solar Street Lights

      Solar light batteries are often deep-cycle batteries. These types of batteries are rechargeable and sustainable, which makes them widely used in the renewable energy sector.

      Deep cycle batteries have cycle times 2 to 3 times higher than automotive batteries and they can extend for up to 3000 cycle times.

      What’s more, you only need to replace them for only 5 to 7 years depending on the type of deep-cycle battery you use. Here are two of the most common types of deep-cycle batteries.

      Regulated Lead-acid batteries are the oldest and the most common batteries for solar street lighting. They are also the cheapest. You may find lead-acid batteries common in cars. There are two types of VRLA batteries – AGM and GEL.

      Generally, they are heavier than other battery types and have a shorter life cycle. That is why most manufacturers prefer Lithium batteries.

      Once in a while, they have to be replenished in a distilled water solution to prolong their life span. Lead-acid batteries can be inefficient in terms of charge and discharge cycles.

      The upside to this type of battery is that they are inexpensive and reliable only if you follow its charging and discharging cycle properly. For solar street lights, the usual price of VRLA battery 150Ah is around $150 to $400 depending on the battery brand.

      1. Lithium Battery

      Lithium batteries are the most common type of solar rechargeable batteries for solar LED street lighting. They sustain almost 4 times discharge, apparently high for batteries. They can also live up to 5 times longer than lead-acid batteries.

      They are practically the best type of battery for solar panels, as well as solar lighting systems.

      Lithium batteries do not require frequent maintenance like lead-acid batteries. This makes it convenient for users. Most batteries can only sustain 500 to 800 charge-discharge cycle times. For Lithium batteries, they can substantially sustain up to 2,000 cycles.

      Lithium batteries are durable as well. They can store up energy for solar lights to be used for many winter or rainy days. The price of Lithium Batteries may range between $400 to $850.

      Lithium Ion Battery and Lithium Iron Phosphate Battery: Which One to Choose?

      There are two types of lithium batteries used in the solar industry. Many people are confused about which lithium battery type is better for their application. Here we discuss how each type can benefit you.

      Below you can find the difference between Li-ion and LiFePO4.

      Lithium Ion Battery (Li-ion)

      Lithium Iron Phosphate (LiFePO4) Battery

      Size:18 x 65 mm26 x 65 mm

      Nominal Voltage:3.7V3.2V

      Voltage of Battery Set: 12V12.8V

      Cost: Cheaper More expensive

      Working temperature:-30 to 65 Celsius-10 to 75 Celsius

      Cycle Life:1000 times2000 times

      Battery Performance

      In terms of battery performance, it would depend on the average temperature in your area. As seen in the table above, Lithium Ion can be more suitable for low-temperature areas reaching -30 degrees Celsius. Hence, they are more appropriately used in the northern hemisphere countries. These countries experience extremely cold climates.

      Safety

      In terms of safety, LiFePO4 is generally safer to use for solar street lighting than Li-ion. This is because LiFePO4 has a more stabilized chemical composition than Li-ion.

      Durability

      Lithium iron can sustain longer charge/discharge cycles than Li-ion, as seen in the table above. This makes it more durable than lithium-ion.

       2. Flow Battery

      For this type of battery, the charging and discharging processes take place between two storages. When the battery is charging, zinc undergoes electroplating and transforms into zinc-bromine. When it discharges, the zinc which is plated on the negative electrodes dissolves in the electrolyte. Then it will be plated again at the next charge cycle.

      The major advantage of flow batteries over lead acid and lithium batteries is that they have 100% depth of discharge.

      This means you can make full use of its energy in a cycle without worrying about the life of the battery.

      In comparison with lithium batteries, you can only use up to 80 to 90% of its energy per cycle as going further can potentially decrease its life.

      However, since this is a new-found battery technology, there’s only a limited amount of suppliers offering this product. It’s also more expensive than lithium batteries.

      Rechargeable Batteries for Solar Garden Lights

      3. Nickel Cadmium (NiCd)

      Nickel-cadmium batteries for solar yard lights and garden lights are often rated at 1.2 V / 500 to 900mA. This type of battery requires minimum management systems and can last for one to two years. A great thing about NiCd is it doesn’t need frequent maintenance as compared with other garden light battery types.

      NiCd can also be used for solar panel battery systems because of their flexibility in extremely large temperature differences. The downside of NiCd is that it needs to be disposed of properly as it emits harmful toxins at the end of its life.

      4. Nickel Metal Hydride (NiMH)

      This brings us to another solar garden light option, which is more environmentally friendly. NiMH is much more eco-friendly than NiCd batteries.

      Nickel Metal Hydride batteries for solar garden lights are often rated at 1.2 V /1000 to 2000mA. NiMH has a larger capacity than its counterpart. This means that NiMH can power your solar garden light longer than NiCd.

      Unlike NiCd, NiMH doesn’t have a memory effect; meaning it would easily remember to charge at its full capacity over time.

      Wrapping Up

      Whether you are looking for solar street light batteries or solar garden light batteries, we hope that this article has helped you choose the best battery type.

      At Clodesun, we develop our LiFePO4 with management systems for high and low-temperature applications. This is to allow efficient monitoring and optimization of the overall battery performance of our solar streetlights. Moreover, the battery’s life can be fully optimized up to its end of life.

      6 Solar Street Light Projects Failure Stories!!!

      In a lot of African countries, installing solar street lights has been a viable option for lighting up the roads. So what fuels the growth? And what do decision-makers need to be aware of when purchasing solar streetlights?

      Why are solar streetlights becoming increasingly popular?

      One of the biggest advantages of a solar street light is that it doesn’t need any other power supply equipment. So, the local government doesn’t need to worry about the installation of other complex equipment. In addition, it is easier to install and does not require complex wiring.

      Secondly, the total long-term cost of having solar street lights is less than running traditional street lights, due to the continuous decline in the cost of battery and solar energy technology. The electricity cost saved by solar streetlights is enough to offset the initial cost of installing them.

      Thirdly, solar street lights, being low-voltage products, are safer than high-voltage electric street lights. Interestingly, that’s exactly the reason that solar street lights are recommended to be used in oil fields, mines, remote gas stations, the chemical industry, and other places with high safety requirements.

      So, what’s the catch then?

      Unfortunately, there are now mixed suppliers in the solar street lights industry, both good and bad.

      To get more business, some greedy manufacturers produce low-quality products with shoddy standard parameters, causing a large number of performance issues which lead to many people opting for electric street lights instead of solar street light products.

      Some customers lost faith in Chinese products. They think that Chinese products break easily. Here are some of the “horror stories” I’ve personally known over the years.

      Story-1: Solar street light project in Bangladesh on fire:

      A Bangladeshi distributor recently complained to the reporters that a batch of split solar street lights which he bought from Zhongshan City, China, caught fire after installation within only 1 year.

      To make matters worse, the manufacturer could no longer be found. His clients were very angry with him and would no longer trust him and his reputation which he had maintained for a very long time was destroyed.

      He reported that he lost a lot of money, but to compensate his customers and regain his reputation, he must find a high-quality manufacturer instead of employing the cheap ones like he used to.

      So what went wrong? From the screenshots of the chat, it can be seen that:

      Image: Recycled ternary lithium-ion lithium battery inside of a poor quality product.

      After disassembly, he found a recycled ternary li-ion lithium battery and a dilapidated circuit board

      Image: A dilapidated circuit board

      The specifications of solar panels written by the manufacturer are 280WP and battery 90Ah, but after the disassembly, it can be seen that the actual solar panel is only 50W and the battery 10Ah.

      Image: Chat history with the manufacturer

       It can be seen from the run-down appearance that the battery used is not the lithium iron phosphate battery claimed by the manufacturer, but a left-over disassembled ternary lithium battery (cell 18650, 3.7V, 2.6Ah).

      Furthermore, the 50W solar panel is too large for the 10Ah battery. Either the manufacturer is unprofessional or he purposefully makes the solar panel look larger to scam his customers.

      Then why did this distributor buy them in the first place? The answer is simple: it’s cheap.

      Story- 2: The Iraqi government no longer believes in solar street lights

      In 2017, the Iraqi government purchased a batch of low-quality solar street lights from Yangzhou City, and all solar street lights broke within 6 months.

      Later, the Iraqi government stopped purchasing solar street light products, and all changed to municipal circuit lights.

      Story-3: The Spanish solar street light project needs after sales of Continuous maintenance

      In 2018, a Spanish engineering company purchased 1,700 sets of split solar street lights from a solar street light factory in Xixiang District, Shenzhen city. After a little more than a year of installation, a large number of street lights broke and required constant repairs and maintenance.

       Later, the manufacturer also disappeared without taking responsibility.

      Story-4: Haiti compensation for losses

      1,400 sets of solar street lights were installed on a national highway in Haiti that broke down within one year.

      When the customer asked the manufacturer to fulfill the warranty commitment, the manufacturer directly blocked the customer and disappeared, which led to the customer developing a negative view of solar street lights.

      Story-5: A senior Pakistani official was arrested

      In 2015, for Pakistan’s 40,000 sets of solar street lights project, a Pakistani female senior official personally searched for Chinese factories.

      A good quality factory quoted a minimum price of 1,300 RMB per unit, but the Pakistani female senior officials demanded 900 RMB per unit, the factory refused as the price was not enough to buy the required materials.

      Meanwhile, another factory promised that it could be done for 900 RMB, and even gave the senior woman a “kickback” commission of 200 RMB per unit, leaving the price of solar street light products to only 700 RMB per unit. How was that possible? To cut costs, the supplier used cheap materials of poor quality.

      It turned out, nearly all 40,000 sets of lamps were broken in less than 6 months. This high-level female official was arrested and has been in jail ever since.

      Story-6: The split solar street lights in Mexico flicker frequently:

      In the middle of the Mexican highway, several street lights are installed, but every single one of them flickers frequently. The road looks very frightening at night.

      The contractor for this project has one year to settle the final payment, but the government refuses to pay for this project since the street lights are defective and don’t work properly.

      Conclusion: Bad practices of poor-quality solar street light manufacturers    

      To summarize, buyers need to be aware of these bad practices.

      Exaggerating the product specs

      The 50W solar panel is marked as 280W, and the 12-15% low conversion efficiency solar panel acts as a 21% high conversion efficiency solar panel.

      LED light source 10W is marked as 100W-200W, low-level LED chips pretend to be high-quality LED chips, such as copper wire connection pretending to be gold wire connection, etc. Low luminous efficiency imaginary labeling is high luminous efficiency. The battery 10Ah is marked as 90Ah, the ternary lithium battery is marked as a lithium iron phosphate battery, and the old battery is marked as a new battery. The lead-acid battery is filled with cement.

      Inexpensive controllers act as MTTP stabilization controllers, reducing the thickness of the light poles.

      Unprofessional service and poor installation instructions 

      Unprofessionalism and wrong specs affect the solar street lights a lot.

      For example, if the pole of the solar street light is kept too high, the light range will be too wide which will result in the light being dull and wasted.

      Here’s an example: poor installation instructions were given to customers.

      Solar panels shouldn’t be placed under some shades

      On the other hand, if the pole is kept too short, the light will be too concentrated and bright. It will also not cover the required area and some spots on the road will be left in the dark.

      In addition, if the voltage of the street light is too low, the light will be very dull while if the voltage is too high, it will cause wastage of light, over-brightness, and higher bills.

      Blocking the customers and disappearing

      Fraudulent manufacturers lie to the customers about the lifespan of the product, promising years’ warranty while the product only lasts months. When the product doesn’t work the way it’s supposed to and the customers demand compensation for the damage, these manufacturers would simply disappear.

      These manufacturers know that they are scamming the customers but these frauds still tell them the wrong specs to get money from their pockets.

      How to pick good Solar Street Light suppliers?

      However, not all Chinese solar street light products are bad of course.

      There is one thing in common among all these stories mentioned above: the buyers all went for astonishingly low prices. It might sound like common sense that low prices can’t buy high-quality solar street lights, but a lot of buyers still think they might get lucky.

      In reality, exceptionally low prices almost always are equal to poor-quality solar street lights. Poor quality solar street lights make you lose money and you will need continuous after-sales maintenance. Some serious cases also lead to the reputation of the distributor being tarnished and him/her going to jail or paying great sums of money.

      It’s a fact that the material used in solar street lights is expensive and the cheap rip-offs can never fulfill the function of high-quality solar street lights.

      The distributors should choose a quality solar street light factory they can fully trust and connect with in case they are unsure about something. Doing this is not only a good monetary investment but will also save them a lot of trouble in case they have some concerns or questions regarding the products.

        7 Questions You Need to Ask Before Starting Solar Light Project

        When you install a traditional commercial solar street light, you don’t often need to be concerned with whether it will be “bright” enough or will operate continuously because there is an expectation that it will work as specified. You trench, lay cables, connect to the utility, and bam—you have light!

        However, if you’re looking to avoid the costly and time-consuming trenching option and you’d rather not pay any ongoing power costs, then a properly-sized modern commercial solar lighting system is a fantastic option. While a solar-powered commercial light can achieve the same lighting results as a traditional light, there are a few specific things you will need to evaluate to ensure you get the right results.

        Why are we asking these questions?

        • Avoid overspending: ensure the lighting system will use properly-sized components for your project needs vs. having an unnecessarily large and expensive system to compensate for poor design.
        • Avoid battery replacements or auto shut-off: install an efficient system that will be able to sustain your light requirements over the long term vs. one that dims the lights, leads to premature failure of the battery, or shuts the lights off completely.

        Q1. Ask About The Project Location

        What is the exact location of the project? Try to get an accurate street address and site description whenever possible.

        Why? This allows the manufacturers to factor solar insolation data into their system design.

        Different areas receive different amounts of sunlight each day. For example, a solar light specified for sunny, southern Los Angeles would be smaller and therefore wouldn’t be able to generate enough power to provide continuous light for Anchorage, Alaska. And a solar light specified for Anchorage would be unnecessarily large for Los Angeles.

        Knowing the project location allows the manufacturers to build and specify their systems for your exact location and to avoid proposing a system that’s too small or too large for your area.

        Also, a street address can allow for the assessment of potential shading hazards—like trees, buildings, or other obstructions—which could block the solar panel from the sun and decrease your system’s performance.

        Q2. Ask About The Project Application

        What kind of area are you trying to illuminate? Knowing the basic street type vs. pathway will change the lighting output requirement.

        Why? The application may affect pole height, pole spacing, and light level requirements. A street, for example, will probably require higher light levels than a trail or park. Here are some possible applications:

        • Shared Pathway
        • Residential street
        • Recreational Reserve
        • Car Park
        • Thoroughfares
        • The entryway to a building

        Q3. Ask About The Project Dimensions

        What is the length of the street/pathway or the size of the general area (for a parking lot, etc.)?

        Why? The size or length of the area will affect the number of lighting systems required, and the uniformity of the light hitting the ground, which all factors into the overall project cost.

        Q4. Ask About The Pole Details

        Is there a specified pole height? What type of pole is required?

        Why? Pole height may affect the number of lighting systems required for the project. Pole type may affect the installation costs.

        Q5. Ask About The Required Light Levels And Uniformity

        Is there a state/municipal standard for light levels for the project, what are they? What light levels need to be met on the ground (measured by foot candles or lux)? What uniformity requirements are there if known?

        Why? Different applications will require different light levels, which plays a large role in determining the overall project cost.

        Q6. Ask About The Operating Profile

        How long does the light need to be on each night? When the light is on, do the light levels need to be met throughout the night or at certain times? If you’re unsure, a good manufacturer should be able to help.

        Why? The operating profile is a crucial aspect of a solar lighting project. Manufacturers will “tune” their systems differently for power management, based on these profiles.

        Here are some examples of operating profiles:

        • Dusk to dawn (all-night operation): the light will run at the same light output level all night.
        • Dim in off-peak hours: for example, the light will run at the required light output level for 5 hours after dusk, then dim to 30% of the required light level. 2 hours before dawn, the light levels will return to 100% until sunrise.
        • Off or dimmed at an exact time: for example, the light will run at the required light output level until 11 p.m., then will turn off.

        Q7. Ask About The Color Temperature

        What color of light is required—warmer (3000K) or cooler (6000K)?

        Why? Color temperature affects the fixture power output and can factor into the project cost. While the light color temperature may be more of a preference than a requirement, cities are leaning more towards lights with warmer color temperatures as they seem to be better for our health and the environment.

        In Summary

        Asking these questions can ensure you’re specified a solar light that will meet your project requirements over the long term at no extra cost. You can also be confident that your lighting system won’t die prematurely or become unnecessarily large, and expensive.
