Integrated solar street light in Philippines

Integrated solar street light in Philippines

The Philippine government began large-scale infrastructure planning and infrastructure construction in 2017, which greatly promoted the development of integrated solar street lights in the Philippines. According to data surveys, the Philippines is now the second largest market for integrated solar street lights in the world. Let me analyze why there is such a large market demand for integrated solar street lights in the Philippines.

The first reason: government policy support Integrated solar street light

1. The Philippines has shifted from an agriculture-based economy to a service industry and manufacturing-based economy. Therefore, the energy industry in the Philippines is a fast-growing economy and a fertile market. The Philippines will add 70 million kilowatts of power generation in the next five years. By 2030, its power generation capacity will double. 16 million people still have no reliable power supply. In such a rapidly growing market, with the increasing trend of distributed power generation, innovative technologies and renewable energy will play a role. The Philippines is seeking to leapfrog a new energy future, and this is a more important moment than ever. Domestic photovoltaic manufacturers and suppliers enter the Philippine market at this time, and it is just the right time!

2. Like many countries in Southeast Asia, the Philippines is also facing the dual challenges of population growth and rising energy demand. Relying on nearly half of its main energy supply imports, the country is highly affected by oil price fluctuations. Frequent tropical storms also adversely affect energy infrastructure. In this regard, the Philippines is determined to strengthen energy security, pursue low-carbon economic development, and make contributions to combating climate change. Renewable energy technologies have become increasingly prominent in national plans and decision-making. In 2011, the Philippine government approved an ambitious NREP project, which aims to achieve 15.3 GW of renewable energy installed capacity by 2030 (three times that of 2010).

3. The Philippines is one of the ASEAN member states, with a population of approximately 105 million people. The annual GDP growth rate in 2017 was as high as 6.685%. The outside world generally holds a positive attitude towards the future economic outlook of the Philippines. The Philippines is located in the Pacific Ring of Fire and has abundant geothermal resources. It is also located in Southeast Asia with sufficient sunshine. It has an average daily sunshine amount of about 4.5-5.5/kwh per square meter. It is rich in sunshine resources and the water resources are also extremely high in the Philippines. Rich, with an average annual rainfall of 2000-3000 mm. However, due to the influence of the geography of the archipelago, some areas have been suffering from power shortages for many years. As the Philippines is in a state of economic growth, the energy problem must be faced and resolved. As of 2017, the PV installed capacity in the Philippines has reached 885MW.

4. The Philippine government has issued various policies to promote renewable energy. It includes policies such as a tax holiday of up to 7 years for income tax and tax-free import of renewable energy technology and equipment. Beginning in 2020, the Philippine Renewable Portfolio Standard (RPS) will officially enter the implementation stage. The policy requires that among the total annual power generation proportion, renewable energy must increase at least 1% each year. The implementation of the policy is expected to stimulate the demand for installed capacity in the renewable energy market.

The second reason: the climatic conditions in the Philippines are very suitable for installing integrated solar street lights

The Philippines is located in the Western Pacific Ocean and Southeast Asia. It faces Taiwan Province of China across the Bashi Channel to the north, and faces Indonesia and Malaysia across the Sulawesi Sea and the Balabac Strait to the south and southwest. It borders the South China Sea on the west and the Pacific Ocean on the east. . …

The Philippines has a monsoon tropical rain forest climate with high temperature, rain, high humidity and many typhoons. The average annual temperature is about 27°C, and the average annual rainfall is between 2000-3000 mm in most areas. The western part of the archipelago has a dry season (11-April) and a rainy season (May-October). The eastern coast has rain all year round, with the most rain in winter. The southern region is also rainy all year round, and there is no obvious distinction between dry and rainy seasons. The Pacific Ocean in the east is the birthplace of typhoons. There are more typhoons from June to November every year.

The capital and largest city of the Philippines, Manila, is one of the most international cities in the world and one of the most diverse cities in the world. It is known as the “New York of Asia”. Manila, the capital city and largest port of the Philippines, is located on the east coast of Manila Bay, Luzon Island, the largest island in the Philippines. It is also called “Little Luzon” and is close to the natural fine harbor-Manila Bay. Manila was built on the banks of the Pasig River.

Manila has a tropical monsoon climate with only two seasons a year. The annual temperature is around 28°C. November-June is hot and humid, and June-October is the rainy season.

According to the monsoon tropical rain forest climate, high temperature, rain, humidity and typhoons, Clodesun also communicates with customers to determine lighting needs, and recommends solar street light styles and solutions based on geographic location and climate characteristics and needs. To determine the installation height, power, and lighting time of the integrated solar street light.

Clodesun hopes that we can also have our own warehouse and office in Manila, the capital of the Philippines, this year, which will help promote our products and make it more convenient for our customers.

led solar street light with pole

Led Solar Street Light with Pole

With green energy energy saving and emission reduction is getting more and more attention, Led solar street light are also more often used in road lighting. The increase in the number of peer companies has also intensified the competition of solar street lights. In order to pursue profits, some companies began to cut corners on the supporting components used in solar street lights. So how to judge the quality of solar street lights? We combine the current problems in the product, focus on the production process of solar poles, so that we understand how to select a good quality Led solar street light pole?

solar street light with pole

First: first look at the plate of the LED solar street light pole.

Many unscrupulous manufacturers use substandard thickness of steel or non-standard steel to fill the good. High-quality steel can withstand more than twelve levels of natural wind, but will not produce shaking or deformation. The quality of substandard manufacturers use non-standard steel, in order to reach acceptance will be sprayed several times to increase the thickness of the solar street light pole.

So to determine whether the quality of the pole is up to standard, it is actually very simple. If you find that the thickness of the pole to meet the standard, then you can test the weight of the pole, if the actual weight does not meet the standard, then the possibility of spraying to increase the thickness exists. At this point you can determine whether the light pole is up to standard by hanging off the spray plastic with a blade.

Second: looking at the workmanship of the light pole.

The production of light poles require that there is no leakage of welding, false welding phenomenon. Welding should be beautiful to ensure that the welding is secure and durable.

Third: look at the galvanization of the light pole.

Legitimate manufacturers are using Q235 steel for the overall hotness of the way to ensure that the light pole will not rust or become rotten. But some manufacturers in order to reduce costs, often using cold galvanized way of processing light poles, although the light pole for cold galvanized will feel the light pole surface bright, but the thickness of the zinc layer is only a few tenths of the hot dip galvanized light pole, its anti-corrosion performance than hot galvanized is also far from. So if you are a purchaser of solar street lights, then this is something you have to pay attention to.

Finally: we must also look at the spraying treatment of the light pole.

Before doing the spraying treatment again, be sure to polish the light pole again. So that the light pole for spraying is only uniform, more pure color. At the same time if the light pole to do the color separation requirements, must observe the color of the light pole at the color separation is clear, is not clear also belongs to substandard products.

And we need to know the general wall thickness of the solar street light pole.

Solar street light pole with how thick, usually depends on how high the pole, single-arm or double-arm lights, 2-4 meters of solar street lights on the general wall thickness of 2.5 cm, 4-8 meters of solar street lights on the general use of 2.5-3.0 cm, 8-15 solar street lights on the general use of 3.0-4.0 cm, this is only the general standard, specific but also according to the wind requirements are different, the light pole thickness is also different.

The commonly used light pole is a steel tapered pole, which is characterized by beautiful, strong, durable, and easy to make a variety of shapes, simple processing technology, high mechanical strength. Commonly used tapered light pole cross-sectional shape are round, hexagonal, octagonal, etc., the taper is mostly 1:9-1:15, wall thickness according to the force of the pole is generally selected in 2.5-5mm.

Solar street light poles are used outdoors, in order to prevent the pole from rusting and corrosion and reduce the structural strength, the pole must be galvanized and sprayed with plastic. Hot-dip galvanizing spraying is mainly a preventive measure against the causes of rust and corrosion. Hot-dip galvanizing spraying can avoid or mitigate the effects of humidity, high temperature, oxidation, chlorides and other factors. The commonly used methods are as follows.

1、Light pole hot-dip galvanizing: The process and method of dipping the pre-treated parts into the molten zinc solution to form zinc and zinc-iron alloy coating on its surface, with a zinc layer thickness of 65-90 um. The zinc layer of the galvanized parts should be uniform, smooth, free of burrs, dripping tumors and excess lumps, and the zinc layer should be firmly bonded to the steel pole, with no peeling and no bulging of the zinc layer.

2、Light pole plastic spraying treatment: hot dip galvanizing and then plastic spraying treatment, plastic spraying powder should be selected outdoor special powder, the coating shall not have flaking, cracking phenomenon. Plastic spraying treatment can be higher to improve the anti-corrosion performance of the steel pole, and greatly improve the beauty and decorative solar street light pole, the color can also have a variety of choices.

For example, 6m solar street light pole product parameters specifications.

1、Specification:Light source is 6 meters from the ground, the material of the pole is Q235 carbon steel.

2, technical requirements (in line with and not less than national standards).

①The light pole adopts conical single bent arm light pole, with bottom diameter 154mm and top diameter 60mm.
②The light pole adopts hot dipped galvanized internal and external surface corrosion treatment, in line with GB/T13912-92 standard, the galvanized surface should be smooth and beautiful. Provide galvanized test report. Galvanized thickness is not less than 85μm.
③Light pole wall thickness ≥4mm, light pole chassis thickness of 22mm.
④Welding surface without cracks, porosity, biting edge, not welded full defects.
The supplier shall ensure that the light pole meets the wind pressure requirements of Wutai County and ensure the normal use of the light pole.
⑤ Service life of 20 years or more.
⑥The width of weld seam is 4-9mm, and the height of weld seam is 0-3mm.
⑦The supplier shall carry out quality inspection of the products before they leave the factory, and carry out comprehensive inspection of the welding quality, dimensional deviation and surface quality.

If it is a 20m width road, it should be considered as a main road, so it needs to be bilaterally laid light before it can be. In addition, the lighting requirements of the road mainly include illumination requirements, illumination uniformity of two, where the uniformity of the general to be above 0.3, the greater the uniformity, indicating that the solar street light of the light scattered more open, the better the lighting effect.

Therefore, we can assume a double row of symmetrical layout, the height of the street lamp pole is at least greater than 1/2 the width of the road, so the height of the pole to 10-12 meters; assume a 10-meter pole, the installation spacing of street lights is generally about 2 times the height of the pole, so the spacing of at least 30 meters; then assume that the solar street lights have a 30-meter spacing, the height of the pole is 10 meters, the power of the solar street lights in this case should be more than 100W, in order to basically meet the lighting requirements of the main road.

Secondly, illumination and power are related to the installation height of the lamps. For solar street light, we hope that the larger the angle of illumination, the better, so that the uniformity will also be good, and can make the spacing of the poles larger, reducing the number of poles installed, saving costs.

Conclusion: Today Belinda intruduce some specicifications about led solar street light pole, hope I can give our clients some suggests which will help you to choose good quality led street light pole.

100w solar street light

Why people do not trust in solar street lights now

Recently, a Malaysian and Australian customer was sad to talk with me and said that they no longer wanted to sell solar street lights because the life of the solar street lights they bought never exceeded two years, I sympathize with their experience deeply.

the solar street light market is very confusing these years, there is no industry standard, customers are always looking for low prices, many solar street light factories in order to make higher profits, they can only reduce the price of their products. Configured or with very poor quality materials, customers was happily think they are buying cheap and good products, but in fact the quality of these solar street lights do not work half a year or even less than two months, which led to more and more people no longer trust in solar street lights.

Following Belinda want to guide you how to distinguish the difference between good quality and poor quality solar street lights.

First :Battery life

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

If you want to buy high-quality solar street lights, Belinda suggest you choose A class A-class LiFePO4 battery or 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 Ternary lithium battery.
solar street light battery difference

Second: Solar panel size

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

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

solar led street light

Third: LED Chip Lumen

210lm/w: Brightness decay in 5 years and more than 80% brightness remained.

110lm/w: Brightness decay in 2-3 years and about 20% brightness remained.

solar led street light

Fourth: Case and Bracket Material

Quality solar street light use customized die-casting aluminum mould, the advantages of die-casting aluminum mould are: light weight, strong and corrosion resistant , anti rust. Making it able to resist strong wind load of up to 130MPH, stainless steel screws are used as fastener to protect against any harsh whether. The die-casting aluminum mould is elegant and characteristics.

Lower quality solar street light just use mould and rough craft, the installing structure need support by knighthead, to recover the structure strength issue, making install more complex, lack of stability and can not anti strong wind.

Fifth: Whether have heat Dissipation between solar panel and light

In summer, the solar panel is as hot as 90°C, 70°C inside the solar lamp body. (we have tested )
Hot will damage battery and LED source, so we separate the hot solar panel and it has a shadow, makes solar street light cool, enlarge lifespan of battery and LED source.

all in one solar light

Six: Whether solar panel can adjust

Different countries and regions have different geographic locations and latitudes. When people install solar street light in some place, on one side, the solar panel can face the sun directly, but on the other side, the solar panel can not face the sun, so if the solar panel can adjustable, it will absorb more solar energy, which can maximize the conversion of solar energy while the lower quality solar led street light panel is fixed, causing low conversion rate of solar and the using areas are also limited.

solar led street light

Conclusion: Solar street lights 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 lights, you will suffer huge losses, so I recommend customers to 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.

solar street light battery

solar led street light battery capacity

With the continued development of solar street lamps, solar street lamp batteries slowly changed from lead-acid batteries to lithium batteries. Therefore, many manufacturers use 20AH lithium batteries with a false capacity to impersonate 80AH to customers, access to large profits, 2014 to 2016, many manufacturers earn a lot of profit by lithium batteries a year.

12V 60Ah lithium battery, for example: the normal use of 3.7V 2Ah cells, 60Ah ÷ 2Ah × 3 = 90 section. When you learn that a 90-section cell has a 12V 60AH capacity, cutting corners requires another upgrade. Yes, the battery cells give you 90 knot cells, but quietly give you 3.7V 1AH instead. At this point the capacity is only 30AH, all of a sudden a lot of cost reduction, for dishonest businesses, this could be profit, or a nuclear weapon to seize the market.

So it is very important to know how to calculate the solar street light battery capacity, sometimes you can avoid being cheated.

How do you calculate the configuration of lithium-ion battery solar street lights?

Let’s take 40W LED light source as an example: the customer requires 8 hours of lighting per day, and 3 days for rainy days.

Let’s take the 18650 lithium ternary battery as an example.

Known conditions: the nominal voltage of a lithium-ion secondary battery is 3.7V; the system voltage of a 40W LED light source is 12V; the platform voltage of three lithium-ion batteries combined in series is 11.1V, and the standard charging voltage of the battery plate is 17.5V.

First, let’s popularize the conversion of Ah (amp-hours) to Wh (watt-hours) units.

Wh (watt-hours) and Ah (amp-hours) are both ways to measure battery capacityAH is a measure of the capacity of an electrical storage device, meaning that the product of current (amperes) and discharge time (hours) in units of capacity [AH] can be satisfied by conforming to the discharge curve (a similar inverse proportional curve).
We often see a number in Wh next to the mAh.
The work done by the battery W = UIt = voltage (V) * current (A) * time (h).
Voltage U*Current I=Power P (Watt, letter “W”)
Therefore, the work done by the battery W=P*t, the unit is Wh.
Ah = Work (W)/Voltage (U)

Daily power required by 40W LED light source = 40W*8H=320Wh
Solar street light design needs to take into account the day’s rainy weather conditions, for example, 3 days in Nanjing design.

Then 3 days 40W LED light source needs total power = 320Wh * (3 + 1) days = 1280Wh
Then lithium battery capacity = work (W) / voltage (U) = 1280Wh/11.1V = 115AH

Through the calculation of solar street lamp battery capacity, the next time we buy solar street lamps, we can better identify whether the manufacturers deceive us, so as to buy a good price, more suitable for our products.

 

solar street light price

30w All in one solar led street light price

Nowadays, more and more places to install solar street lights, the price is of course the first concern; many customers come to the consultation, usually directly asked how much a 30w solar street lights ? Or how much does a 60w solar street light cost?

When you go to ask the solar street light manufacturers “how much does a 6 meter solar street light cost?” The Clodesun is sure that many customers receive many quotes for different solar street light prices. Some quotes are high, some are very low, and the competition for solar street light prices varies, why is this?

Because we this problem itself is not standard and unified configuration parameter requirements, so each solar street lamp manufacturers offer solar street lamp price will be different and not offer a problem and different parameters price are not the same, solar street lamp price market is very confusing, no uniform standard, more than 80% of the product is unqualified, not in accordance with the contract standard manufacturing. The main reason is, LED lamps and lanterns, photovoltaic plate wattage, lithium battery capacity, general customers can’t detect, make jerry-built manufacturers have the opportunity.

What are the factors that affect the price?

1、Battery components
The power of the solar module and the capacity of the battery. High power, large capacity configuration, is bound to pay a higher cost; otherwise, it is lower.

2、Galvanization method
Galvanizing poles are hot and cold plating, cold plating is directly electrolytic to galvanize, the process is simple, so the cost will be low, but cold plating will make the poles are not very rust-proof, and hot galvanizing process is more complex, need to heat the electricity, galvanized again, consume more energy than cold plating, the price is higher than cold galvanizing a gear, of course, hot galvanizing can make the poles 20 years without rust.

3、Use of equipment and materials
The production of solar street lights is inseparable from these two, good equipment, solar lamps complete collection of information, then the price of solar street lights also rose!

4. Regional
Region is also one of the important factors affecting the price of solar lights, not the same region to withstand the sun is also a limit because of the impact of the time of year and climate, the price of solar street lights is not the same.

5, the size of the street lamp manufacturers
Street lamp manufacturers large scale, clear division of labor, large volume, but the price will be low, and at the same time have a professional after-sales service, on the contrary, a lot of small manufacturers of the expenses, the price will naturally go up.

solar street light battery price

All in one solar street light battery price

With the increasing maturity of new energy technologies, the country vigorously pursues energy conservation and emission reduction, the application of solar street light system is becoming more and more widespread, then as the core of its system of an accessory, How many kinds of solar street light and what are the prices of different batteries?

Solar street lamp battery currently on the market are mainly lead-acid batteries, colloidal batteries, ternary lithium-ion batteries and lithium iron phosphate batteries four.

1 lead-acid battery

Lead-acid batteries are composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The important advantages of lead-acid batteries are relatively stable voltage, cheaper price and high security; the disadvantage is that the service life of lead-acid batteries is relatively short, the volume is much larger than ordinary batteries, but because of its price advantage, it is still dominant in the use of solar street lamp industry.

2. colloidal battery

It is equivalent to an upgraded version of lead-acid batteries, maintenance-free and less maintenance, and importantly, it replaces the sulfuric acid electrolyte with a colloidal electrolyte internally, which improves the storage capacity, discharge capacity, safety performance and life expectancy.

Gel batteries can be used within the temperature range of -40℃~60℃, with better low temperature performance, and are the best choice in the northern alpine region or tropical areas where the temperature is higher; their anti-vibration performance is also very good, and can be used safely under a variety of harsh conditions, and their service life is double or even more than that of ordinary lead-acid batteries.

3. ternary lithium ion battery

High specific energy, small size, fast charging, high price, its deep cycle times of 500 to 800 times, life and gel batteries are almost the same, the temperature range of use is -15 ℃ ~ 45 ℃. But ternary lithium-ion batteries also have disadvantages, poor safety, if the battery is not very stable inside, or unqualified manufacturers of ternary lithium, it is very likely to explode in the process of overcharging or higher temperatures.

4. lithium iron phosphate ion battery

High specific energy, small size, fast charging, good stability, temperature range is also wide, but the price is the highest of all the batteries, due to cost issues have not been large-scale implementation of the use.

Most solar street light systems currently use lead-acid batteries and colloidal batteries, some use lithium batteries, then how to maintain it in the course of use?

①Prevention of overfilling

Solar street lamp battery life depends on external maintenance, but also with the internal heat accumulation is closely related to the solar battery if overcharged, it will make the battery internal temperature rise step by step, the phenomenon of thermal runaway.

Prevention of insufficient voltage

In addition to preventing over-charging, solar cells should also prevent under-charging, always under-charging then may also be a problem with the racking system, or the voltage is too low to cause, often under-charging will lead to a reduction in the number of cycles, which will also shorten the life of the battery.

(3) Prevent over discharge

The discharge depth of the battery is closely related to the designed charge/discharge cycles (service life) of the battery.

④ Control the ambient temperature

Especially high temperature environment will shorten the life of solar battery by half, the life of the battery is longer in normal weather, but in high temperature, the battery will suffer; if it is used in extreme low temperature or high temperature environment, it is recommended to use the gel battery with a wide range of temperature application.

The price of lithium solar street lamp battery includes lithium solar battery cells, battery special material, the ease of design, time consuming costs, assembly costs, solar street lamp battery pack transportation costs for the overall tax quotes, with special requirements of the lithium solar street lamp prices are higher.

Solar street light operation & maintenance

Solar street light operation & maintenance

Solar street lights in the process of installation and construction, not only to consider the solar street light hardware, solar street light installation and construction, project management and quality control is also very important.

Solar street lights installed outdoors, should pay attention to the following issues: anti-corrosion of all exposed parts;  wind resistance of all connected components; solar panel bird protection; solar panel security; street lamp access lines and control room rain; battery insulation in winter and summer cooling; battery room ventilation; battery room waterproof; battery security; lighting rain, insects, hail. Lamps to facilitate maintenance and replacement; controller to facilitate maintenance and testing.

Pre-operation and maintenance of solar street lights

Solar street light project is a long-term and arduous project, which requires long-term investment of the construction unit, but also requires the common attention and efforts of the whole society. At present, Clodesun has installed nearly 8000 sets of solar street lights.

Fellowing  are the steps of solar street light installation?

1 – Foundation pouring

Determine the location of the standing light pole; reserve (excavate) a compliant pit at the location of the pole; the pit should be poured concrete capable of carrying 1.5 times the weight of the pole, and the pole should be placed in a ground cage with an embedded part. The embedded part is placed in the center of the square hole, with one end of the PVC threading pipe placed in the center of the embedded part and the other end placed in the battery storage area.

Care is taken to keep the embeds, base and original ground at the same level (or the tops of the screws at the same level as the original ground, depending on the needs of the site) and one side must be parallel to the road; this ensures that the light poles are upright and the back end is straight and not skewed. They are then poured and secured using concrete not low in C20. After the construction is completed, the mud residue on the positioning plate is cleaned in time, and waste oil is used to clean the impurities on the bolts.

2-Mounting the solar module

Measures must be taken to avoid short-circuiting the solar panel before connecting the positive and negative outputs of the solar panel to the controller. The solar module must be securely and reliably connected to the mounting bracket; the module’s output wires should be protected from exposure and secured with cable ties; and the solar panel should be oriented with the compass pointing south.

3-Lithium battery installation

Batteries must be handled with care when placed in the control box to avoid damage to the control box. The wires connecting the batteries to each other must be bolted to the battery terminals and copper spacers should be used to enhance conductivity; after connecting the output wires to the batteries, short-circuiting is prohibited under any circumstances to avoid damaging the batteries; the output wires of the batteries must be connected to the controller on the pole through PVC pipe. After completing the above operation, please check the wiring of the controller to prevent short circuit. After checking the wiring, please close the door of the control box.

4-Lamp head parts installation

Fix the components of each section: fix the solar panel to the solar rack, fix the lamp head to the pick arm, then fix the rack and pick arm to the main pole and run the connection cable through the control box (battery box).

Then check that the simple commissioning system is working properly. Loosen the solar panel cable from the controller to make the light work; connect the solar panel cable and turn off the light; at the same time, watch carefully for any changes in the indicator lights on the controller; all being well, lift and install and place the batteries in the battery box.

Debug the system to see if it is running properly; release the solar panel cable on the controller, and the light is on; at the same time, connect the solar panel cable, and the light is off; then carefully observe the changes in the indicator light on the controller; everything is normal, before sealing the control box.

Solar street lights throughout the year, 0 electricity, easy to install, energy saving and environmental protection, but solar street lights can not be used in any one environment, solar street lights are not only geographical requirements, there are requirements for temperature and humidity, today let’s talk about the extreme environment can not use solar street lights!

First of all, in windy areas, solar street lights are generally wind-resistant grade 12, for more than 12 typhoons in the region, if you use solar street lights, it will cause immeasurable impact, but the domestic wind is generally below grade 8, so the general domestic areas can be used!

Secondly, Solar street light working temperature between -50 ° C and 70 °, if the temperature is too high, the normal operation of the various components of the solar street lamp will have an impact, but also because the solar street lamp is an electrical system, in the use of the process will generate heat, the temperature is too high not only on the normal functioning of the components have an impact, but also prone to fire, resulting in losses, if the temperature is too low, the operation of the solar street lamp system will slow down, especially the battery activity will be reduced with the lower temperature, easy to slow down the operation of the system.

Thirdly, Solar street lights in the 8 earthquake area is not good to use, the general level of earthquake resistance of the solar street lights is 8, if installed in the earthquake zone, it is easy to cause unpredictable damage to the solar street lights.

Finally, Solar street lights in the humidity greater than 80% of the area can not be used normally, humidity is too high, the electronic components are susceptible to moisture oxidation, resulting in unstable electronic components link, it is easy to affect the normal lighting of the solar street lamp system.

In order to ensure the quality of the project, Clodesun devoted a lot of energy to assist the construction side to develop a set of project management methods, directly involved in the quality control of solar street lamp components, on-site materials, and the quality of the project. And quality inspection of components, quality control of the installation process, as well as the implementation of solar street lamp post-management responsibility system.

Why all in one solar street lights widely used?

With the development of science and technology of All in one solar street light, some obvious problems have always been the biggest constraint on the development of the traditional lighting industry. That is the development trend, green energy conservation and work efficiency, the use of solar energy and wind energy is the inevitable trend of lighting industry development, then in lighting choice, how to choose? Today, we will make a comparison between the traditional sodium lamp and the solar LED lamp, and take a brief and clear look at it!

First, energy compared to solar energy is inexhaustible, clean, pollution-free and renewable green energy. Solar power generation, unparalleled cleanliness, high safety, photovoltaic energy is considered to be the most important new energy in the 21 century.

Lights only need solar power to maintain normal daily work, without the need for standard electricity to provide lighting. Solar energy or clean renewable energy, in line with the concept of green environmental protection. They are not connected to the grid infrastructure, but are completely independent or offline.

And under the same operating conditions, the solar LED lamp has low power and low energy consumption. Conventional (metal halide or high-pressure sodium) streetlights generate electricity from the standard grid, which generates energy from fossil fuel (non-renewable) sources. Second, the structure comparison from the structure, solar street lamps do not need to lay cables, no AC power supply, do not generate electricity; DC power supply, control.

Second, Long life, high luminous efficiency, simple installation and maintenance, high safety performance, energy saving and environmental protection, economic and practical advantages. Can be widely used in the main city, secondary roads, residential areas, factories, tourist attractions, parking and other places. Self-made system, do not need market power support, even if there is a fault, maintenance is also very convenient, just need to replace the corresponding module.

But the traditional street lamp needs the market electricity to run, the whole system will be paralyzed because of the breakdown of the city electricity, each lamp of the solar street lamp is an independent system, even if one lamp breaks down, it will not affect the work of the other lights! Solar energy lamps are relatively extensive and adequate, long-life and maintenance-free are far from comparable to electricity.

Third, the efficiency of solar street lamps through photoelectric conversion, solar street lamps using the new LED technology, can provide brighter light, reduce the use of energy. LED lamps with fewer watts are more efficient than traditional lamps, helping to reduce energy consumption while providing higher luminosity. Led lamps are also less likely to fail, with an average operating time of 50000 hours.

While the working hours of traditional street lamps are between 5000 and 8000 hours, and the failure rate is higher and the brightness is higher, the power consumption is 1/10 of the incandescent lamp and the fluorescent lamp is 1/3, but the life span of the lamp is 50 times that of the incandescent lamp, and the life of the fluorescent lamp is 20 times that of the fluorescent lamp, which is the successor to the incandescent lamp. Fluorescent lamps, gas discharge lamps after the fourth generation of lighting products.

With the development of solar energy becoming more and more mature, technology becoming more and more perfect, the application field of solar energy is more and more extensive. Compared with other fields, the application of solar energy in lighting system is relatively mature, while science and technology are still developing continuously.

The basic development of traditional lighting industry has come to an end, so solar road lighting system has become an inevitable trend of development! At the same time, compared with the application and development of solar energy on the ground, entrepreneurs are more interested in the benefits brought by the solar lighting system.

the solar street light system has a high cost, a large profit manufacturer likes, and at the same time, because of its convenient use and beautiful appearance, Energy conservation, environmental protection, advanced technology, at present more and more enterprises have developed in this field, the major manufacturers, including municipal, and even civil demand, complete the transformation step by step.

The first is the promotion of market demand, the second is the trend of scientific and technological progress, the third is the concept of green energy-saving and environmental protection. All pointed out the direction of the development of solar lighting system, so that the development prospects of this field is only just beginning, there is still a large market worth exploring in the future!

Difference between solar street light and street light?

The All in one solar street lights uses sunlight as energy, absorbs sunlight during the day and converts it into electrical energy, which is stored in the battery. At night, the battery is discharged through the battery to supply power to the lights source.

There is no need to lay complex lines. It is green, safe, energy-saving and durable. Save a lot of electricity and maintenance-free. The integrated solar street lights has become the darling of road lighting, and it has attracted more and more attention from the general public. Let’s talk about it. What is the difference between the integrated solar street lights and the city circuit lights?

  1. Comparison of installation

 The installation of the integrated solar street lights is relatively simple, without slotting or cable laying, only need to build a cement base and fix it with stainless steel screws, which saves the installation cost. The traditional city circuit lights needs to use complicated procedures during the installation process, which requires a lot of manpower and material resources for engineering construction, such as cabling, trenching wiring, pipe threading, and backfilling.

  1. the cost comparison

 All integrated solar street lights use natural light to convert into electrical energy for illumination. Integrated solar street lights are a one-time investment and long-term benefits. Although the initial investment cost is relatively higher than that of the city circuit lights, it will not generate high electricity costs and maintenance costs in the later period. The cost can be recovered in 6-7 years, and more than 1 million electricity costs and maintenance can be saved in the next 3-4 years. cost. Electricity street lights are expensive, and conventional power city circuit lights can use one kilowatt hour a night, and require long-term uninterrupted maintenance of the route, especially in the case of long-term rainy and windy weather, unstable voltage, replacement of sodium lightss and The cost of aging maintenance lines is increasing year by year.

  1. Comparison of maintenance

 Each integrated solar street lights has an independent system, even if one of them has problems, it will not affect the normal use of other street lightss. The city circuit lights need to be laid with underground cables, so once there is abnormal power supply or cross construction of water and gas pipelines, it will bring many hidden dangers, maintenance will cause difficulties, and consume a certain amount of manpower and resources.

  1. Comparison of safety

 The integrated solar street lights is an ultra-low voltage product, which is safe, reliable and non-hazardous during transportation. The city’s circuit lights will be affected by many factors, such as: construction quality, abnormal power supply, product aging, scene engineering transformation, water and electricity pipeline transformation, and many other factors, which bring many hidden safety hazards.

      5. Comparison of use

 The integrated solar street lights is put into use directly after installation, without manual management, the working mode and working brightness of the integrated solar street lights can be controlled through the smartphone app, the relevant operating data of the controller can be read, and displayed on the APP interface . The city circuit lights need to be managed manually, which increases the management cost virtually.

     6.Comparison of energy saving

 The integrated solar street lights uses solar energy to generate electricity without consuming conventional power, and the solar street lights uses LED light source, which is energy-saving and environmentally friendly. The city circuit lights need to be connected to the regular city power in order to be used normally.

battery of solar street light

Four kinds of solar street lights batteries?

Solar batteries are the main accessories in solar street lights. Currently, there are four types of batteries: lead-acid batteries, gel batteries, Li ion lithium batteries, and LiFeP04 lithium batteries. The four types of batteries commonly used in solar street lights. Which battery is the best? Let’s take a look at the characteristics of these four batteries:


1. Lead-acid battery
The plates of lead-acid batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage of lead-acid batteries is that the voltage is relatively stable and the price is relatively cheap; the disadvantage is that the specific energy is relatively low, so the volume is much larger than ordinary batteries. The service life of lead-acid batteries is relatively short, generally 300-500 deep cycles. Maintenance is relatively frequent, but because of the price advantage, it is still widely used in the solar street lamp industry.

2. Gel battery
It is equivalent to an upgraded version of lead-acid battery. It is maintenance-free and solves the frequent criticism of lead-acid battery maintenance. Internally, colloidal electrolyte is used instead of sulfuric acid electrolyte, and the storage capacity, discharge capacity, safety performance and life are improved. , But sometimes even surpass the ternary lithium battery in terms of price. The gel battery can be used in the temperature range of -40 ℃-65 ℃, the low temperature performance is better, and it can be used in the northern cold regions. It has good seismic performance and can be used safely under various harsh conditions. The service life is double or even more than ordinary lead-acid batteries.


3.   Li-ion lithium battery
The advantages of  Li-ion lithium batteries are many. It has high specific energy, small size, fast charging and high price. The number of deep cycles is about 500-800 times, the life is similar to that of gel batteries, and the temperature range used is -15℃-45℃. However, the ternary lithium battery also has disadvantages, and its battery is not stable inside. If it is a  Li-ion lithium battery produced by an unqualified manufacturer, it may happen that it may explode during the overcharge process or in a high temperature environment. .


4. LiFeP04 Lithium  battery

LiFeP04 Lithium  battery is a battery that integrates many advantages. It has higher specific energy, small size, fast charging, long service life and good stability, but the price is the highest of all batteries. The number of deep cycle charging is generally 1500-2000 times, a group of lithium iron phosphate batteries under normal use, can generally be used for 8-10 years, can be used in an environment of -40 ℃ -70 ℃, the use of temperature The scope is relatively wide.

1.The charge and discharge times of LiFePO4 Lithium battery is 2000 times, but Li-ion Lithium battery is only 800 times. Lifespan of LiFePO4 is 2.5 times than Li-ion.

2.In hot summer LiFeP04 Lithium battery is stable, but Li-ion Lithium battery is easy on fire.

 3. LiFePO4 battery is twice expensive than Li-on lithium battery, and more stable. Lifespan of LiFePO4 10 years, Li-ion battery only 4 years.


It can be concluded from this that the use of  LiFeP04 Lithium  battery in solar street lights is of course the best, but the price is relatively high. LiFeP04 Lithium  battery is a domestically developed energy storage battery with mature and independent independent property rights.

There are many manufacturers, and the use conditions and safety protection are also very well done, so the use of lithium iron phosphate battery is the best choice. Questions about solar street lights and solar batteries are welcome to interact with Belinda or Clodesun.com.
