integrated solar led street light price

Integrated solar led street light price?

Although the integrated solar led street lights price is higher than traditional street lights, it is energy-saving and does not need maintenance frequently. that is why the current traditional street lights are replaced by integrated solar street lights.

Integrated solar street light

With its energy-saving and environmentally friendly features, integrated solar led street lights have been admired by people in recent years. They are charged during the day and illuminated at night without the need to lay complicated wires and pipes. It has many advantages, low maintenance costs, power-saving, and durability, saving the city. More resources are in line with the development concept of green earth, energy-saving, and emission reduction.

The most important part of the procurement process is to judge the price list of integrated solar led street lights. First, we must take a rough look at the price of solar street lights, and then analyze in-depth, analyze the cost, configuration, value, and other aspects of solar products to see if the price list of solar street lights provided by solar street light manufacturers is true.

Integrated Solar street lights may have the same price and different configurations; there are also the same configurations, but the prices are different. Under these circumstances, we have to analyze and judge the price list of integrated solar street lights, following three points:

1. Is the configuration of the integrated solar led street light price list complete?

All in one solar led street light

During the procurement process, solar street light buyers will ask solar street light manufacturers for a solar street light price list. The complete solar street light price list should have the basic information of the solar street light manufacturer.

Followed by the product description, which includes the total number of products. Prices, price details, pictures, materials, dimensions, specifications, etc., and also pay attention to the product’s warranty description and delivery form. The more complete the solar-led street light quotation table, the more trustworthy it is.

2. Is the configuration of integrated solar led street lights price reasonable?

In addition, to check whether the solar street light quotation table is complete, it also depends on whether the solar street light configuration is reasonable. The configuration of the solar street light is communicated in advance between the purchaser and the manufacturer because the solar street light manufacturer makes a reasonable configuration according to the needs of the purchaser, and the configured combination must meet the needs of users without excessive waste.

3. Compare several integrated solar led street light manufacturers price

If the price list of integrated solar led street lights is complete and the configuration is reasonable, the next step is to look at the price of solar street lights. You can find different manufacturers with the same configuration for comparison. If the price quoted by the solar street light manufacturer is significantly lower than the market reasonable price, it indicates that the product itself will have some problems, and the price is higher than the market reasonable price and will not be considered cost-effective, so we must carefully consider before making a decision.

Integrated Solar street lights are developing in the direction of high quality and high added value, but it is inevitable that some manufacturers will shoddy, so you must be careful when purchasing, and you must follow the above points when choosing to avoid falling The trap of product quality.

Do solar street lights need to replace the battery?

The life of other accessories of solar street lights can last over 10 years, but solar street light battery usually needs to be replaced after 3-5 years, so the key is the battery life and quality that influenced the solar street lights life.

All in one solar street light is an independent power generation lighting system, it is composed of a battery, solar street light pole, LED lights, battery, solar street light controller, and other components.

No need to connect to the mains, the solar panel converts light energy into electrical energy during the day and stores it in the solar battery, at night the battery supplies power to the LED light source to make it shine.

solar street lights battery

1、Solar led lights panels

We all know the solar panel, it is the whole system of power generation equipment, it is composed of silicon wafers, the service life is very long, can reach about 20 years of life.

2、Solar led LED light source

LED light source is composed of at least a few dozen light beads containing LED chips, theoretical life of 50,000 hours, normal is by can reach about 10 years.

3、Solar led Street light pole

Solar Street light pole is made of Q235 steel rolled pole, the whole hot-dip galvanized treatment, hot galvanized anti-rust, and anti-corrosion ability are strong, so at least to ensure 15 life.

4、Solar led street light Controller

General controller waterproof sealing grade is high, the normal use of 10-15 years is no problem.

5、Solar led street light Battery

Solar street lights are currently mainly used in the battery is a gel maintenance-free battery and lithium batteries. Gel battery life normal 2 to 3 years, lithium battery life normal in 5 to 8 years. In normal use, 3 to 5 years is the time to replace the battery, because, by 3 years or 5 years, the actual capacity of the battery is much lower than the initial capacity, affecting the lighting effect.

In general, the key to the service life of solar street lights is the battery, when buying solar street lights, it is recommended that the battery should be configured to be larger, to develop the life of the battery is its cyclic discharge life, complete discharge is about 500 to 800 times.

If the capacity of the battery is only enough to discharge every day, then the battery is easily damaged, but the capacity of the battery is several times the daily discharge, which means a few days to have a cycle, which greatly increases the life of the battery, and the capacity of the battery is several times the daily discharge, is to ensure that the number of consecutive rainy days is longer.

The service life of solar street lights also lies in the usual necessary maintenance, in the early stages of installation, to strictly follow the construction standards to do, in the configuration is also as reasonable as possible with, increase the capacity of the battery, so as to extend the life of solar street lights.

all in one solar led street light

The current 8-year non-replacement battery has in fact been such a product, the battery used in our solar street lights is designed not to be replaced for 8 years. Let’s put it this way, there is a lithium-ion battery with a cycle count of 2,000 cycles, which means no replacement within 5 years,

Our new German designed solar street light has been on the market since 2008, according to all the statistics conducted worldwide the proportion of bad batteries after use is less than 0.5% (no need to replace)

The fact that the batteries in our products are not replaced within 5 years is very normal and a fact, plus our new invention of a battery technology patent (a technology to extend the life of the battery) in 2012 on the basis of which the life of the design is 8 years without replacement.

How to judge the quality of Led Solar Street Light with Pole

How to judge the quality of led solar street lights?

We did a clear investigation so that we can choose high-quality LED solar street light poles?

With green energy-saving and emission reduction is getting more and more attention, Led solar street lights are also widely used in road lighting. The increase in the number of peer companies has also intensified the competition for solar street lights. In order to pursue profits, some companies began to cut corners on the supporting components used in solar street lights with poles.

solar street light with pole

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

Many unscrupulous manufacturers use the 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 meets 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 solar street light pole.

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

Third: look at the galvanization of the solar street 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 ways of processing light poles.

Although the light pole for cold galvanized will feel the light pole surface bright, 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 solar street 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.

led solar street light with pole

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 shapes 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 with pole parameters specifications.

  1. 1、Specification: Light source is 6 meters from the ground, the material of the pole is Q235 carbon steel.
  2. 2, technical requirements (in line with and not less than national standards).

①The light pole adopts a conical single bent arm light pole, with a bottom diameter of 154mm and a top diameter of 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 the weld seam is 4-9mm, and the height of the weld seam is 0-3mm.
⑦The supplier shall carry out quality inspection of the products before they leave the factory, and carry out a comprehensive inspection of the welding quality, dimensional deviation, and surface quality.

If it is a 20m width road, it should be considered as the 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.

solar street light project

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 introduces some specifications about the led solar street light pole, hope I can give our clients some suggestions which will help you to choose good quality led street light pole.

solar street light battery

Solar led street light battery capacity

With the continued development of solar led street lights, solar street light battery types changed from lead-acid batteries to lithium batteries. So how to calculate the battery capacity of solar-led street lights?

Many manufacturers use 20AH lithium batteries with a false mark capacity to impersonate 80AH to customers, access to large profits, 2014 to 2016, many manufacturers earn a lot of profit by lithium batteries these years.

solar led street light battery

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 a 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.

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 capacity 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
The 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 light battery capacity, the next time we buy solar street lights, 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

When you ask the solar street light manufacturers “the price of 30w all in one solar led street light?” customers will receive many quotes for different prices. Some quotes are high, some are very low, and the competition for solar street light prices varies, why is this? Since there is no unified standard and uniform configuration parameters for integrated solar street lights, different solar street light manufacturers have different prices.

Therefore, The price market of solar street lights is chaotic. More than 90% of solar street lights are of substandard quality because they often do not manufacture according to contract standards or replace materials with worse quality in order to obtain higher profits. The main reason for this is that LED lighting, photovoltaic panel wattage, and lithium battery capacity all have different levels, and generally inexperienced customers cannot perceive the difference in quality.

What are the factors that affect the 30w solar street light price?

price of solar led street light

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 the 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
The 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 solar street light manufacturers
Street light 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 operation & maintenance

Solar street light operation & maintenance

Although the installation of integrated solar street lights is very simple, Solar street light operation & maintenance is not easy, we may encounter many problems during the installation process, and after the installation is completed, later maintenance is also very important, which can assure our solar street lights for a long life span.

Pre-operation of solar street lights

Solar street light project is a long-term and arduous process, which requires a 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.

solar led street light install

Following 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 circuits. 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.

How to maintain solar integrated street lights

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 light 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.

Solar street lights have zero electricity, are easy to install throughout the year, 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, but there are also 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 light will have an impact, but also because the solar street light 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 are 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 light 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.

Difference between solar street light and street light?

The All in one solar street lights use sunlight as energy, absorbs sunlight during the day, and convert 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. It is green, safe, energy-saving, and durable. Save a lot of electricity and be maintenance-free. The integrated solar street lights have become the darling of road lighting, and it has attracted more and more attention from the general public.

When there is road construction, People are wondering whether to choose solar street lights or street lights, What is the difference between them.

solar street light supplier

  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 need 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.

solar led street light

cost of solar street light

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 lights and The cost of aging maintenance lines is increasing year by year.

  1. Comparison of maintenance

 Each integrated solar street light has an independent system, even if one of them has problems, it will not affect the normal use of other street lights. The city circuit lights need to be laid with underground cables, so once there is an 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 are 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 the use

 The integrated solar street lights are 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 use solar energy to generate electricity without consuming conventional power, and the solar street lights use 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.

Conclusion:

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 are 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

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

Gel battery


It is equivalent to an upgraded version of a lead-acid battery. It is maintenance-free and solves the frequent criticism of lead-acid battery maintenance. Internally, the 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

Li Ion 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 processor in a high-temperature environment. 




4. LiFeP04 Lithium  battery

solar street light battery price

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. The lifespan of LiFePO4 is 2.5 times that Li-ion.

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

3. LiFePO4 battery is twice expensive as Li-on lithium battery, and more stable. The lifespan of LiFePO4 is 10 years, Li-ion battery is 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 property rights.

There are many manufacturers, and the use conditions and safety protection are also very well done, so the use of a 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.

10 reasons for choosing solar led street lights

solar street lights it’s one of the systems where people use them the most. Here are 10 reasons why people prefer choosing solar-led street lights.

solar new clean energyWhile there are many nations that’ve been pushing the use of solar energy for street lights, there are still some nations that haven’t followed the same pattern due to various reasons. Some have ignored its potential, some don’t have the funds for it, some are working on it and some just don’t get enough sunlight.

We should push more and more people to use solar power and more specifically solar integrated street lights as it’s one of the areas where people use it the most. It offers a wide range of benefits and today we have ten of them listed below.

Renewable Energy Source:

Solar integrated street lights use renewable energy which means that there are no harmful byproducts. It does not have a negative impact on the environment and neither does it require an investment that big power plants like hydro and geothermal need. They always get replenished right away and never get depleted. This ensures that there’s never any absence of energy source except of course some cloudy days.

Unlimited Energy:

Solar energy is practically unlimited. The Sun is very massive and the amount of energy it has is just as much. The star was born millions of years ago and still stands strong with its light and heat energy. It is not going to die in millions of years to come so that makes it pretty much unlimited. It would be foolish not to tap into it and enjoy its benefits

Minimum Operational Cost:

While setting up solar panels the initial costs may seem overwhelming but after that, the costs of operations are quite minimal. With the off-grid nature of solar street lights, the operational costs incurred is very low. Each has its own solar panels and a battery that is damaged doesn’t affect the rest of the lights in the same street. It only needs light regular servicing as it isn’t as complicated as traditional street lights. They have minimal complexities and hence do not need frequent repairs.

Conserve energy:

Almost all solar integrated street lights make use of sensors to toggle the lights on and off. Most of them nowadays have light sensors that trigger the lights depending on the amount of light available. When it gets dark, the lights turn on and when it starts getting brighter, the lights turn off. This is pretty smart and needs to be implemented everywhere. Some traditional street lights do have some automatic system but most of them are just timers. With our solar integrated street light, we assure you that you definitely will conserve a significant amount of energy.

No accidents:

These lights come as standalone units and are fitted into a single piece of technology. There are no wires that dangle outside and it’s just a single piece of hardware. Such an absence of external wires makes it much safer than conventional street lights. With zero dangling wires, solar street lights pose no threats of accidents like overheating, strangulation and electrocution.

Save Money:

Getting electricity from a grid will cost a lot of money especially considering that the street lamp will be lighting up throughout the night. Instead of doing that we can instead go solar street lights as they don’t have fees like power grid lines. Yes, countries do charge tax for it but that’s way lesser than the fees for regular electricity lines.

Almost zero power cuts:

Solar street lights are super-efficient and hardly get a breakdown. Furthermore, since they’re not connected to any central grid or plant, they light up the streets throughout the night irrespective of any power cuts or grid failures. They run on their own and even if they do break down, it doesn’t happen to the lights at once. And since they have their own independent units, one’s breakdown doesn’t really affect the other.

Easy to install:

Solar integrated street lights have a very simple setup. They do not have a complicated wiring system like on traditional street lights. Solar street lights come with minimal setup needs and have very few steps to follow before the lights are up and running.

Government offers:

In many countries, the government is giving lucrative offers to promote the use of solar panels. They have deals like interest-free loans, heavy discounts, tax discounts, rewards, exchange programs, and so on. We should take this opportunity and tap into the market. We should make use of such offers and get solar integrated electronics before they get over and you get obliged to buy them without any deals.

Flexibility:

Solar integrated street lights are also quite flexible. They come in handy for remote areas which are far off any power grid. Such places often have difficulties in accessing electricity, but these solar street lights just need the sun’s rays and nothing more. They can enjoy the features of street lights even without having any power grids nearby.

Conclusion:

The integration of solar street lights is the future development trend of street lights. I hope that everyone will seize the opportunity to break through some technical problems of solar street lights, the clodesun is always with you, we will concentrate on solar street light in the future

How to choose good quality solar led street lights

Whether it is on the main roads of the city, or on the roads and alleys in the country, whether in the factory or in the community, we can always see solar-led street lights. It is widely used in our lives. However, there is no uniform standard in the solar street light industry, so the quality of solar street lights from various manufacturers will be different, so how can consumers choose a good quality solar street light?

We mainly consider the following three aspects: solar panels, solar cells, and solar controllers.

1. How to choose a solar led street light controller

In the solar power generation system, the solar controller is a device that controls the solar battery to charge the battery and supply power. It works continuously throughout the day. It is best to control its power consumption below 1mAh to avoid consuming excessive power and affecting power generation efficiency. It is best to have a three-phase charging control mode of strong charge, balanced type, and floating charge to ensure power generation efficiency.

The choice of controller type is very important:

The choice of controller is often an issue ignored by engineering companies. The quality of the controller varies, and the market price of 12V / 10A controllers ranges from 100-200 yuan. Although it is the smallest part of the entire street light system, It is a very important link. The quality of the controller directly affects the component life of the solar street light system and the use of the entire system.

(1) A solar controller with automatic power reduction should be selected. This controller can automatically reduce the output power of the load according to the remaining capacity of the battery. When the battery capacity is insufficient, the controller reduces the output current. After the battery capacity is restored, the controller restores the original output current to achieve the effect of power-saving. This function is very useful.

To select a controller with high charging efficiency, a controller with MCT charging mode can automatically track the maximum current of the battery board to avoid unnecessary charging waste.

Controllers with power adjustment should be selected. Controllers with power adjustment have been widely promoted, which can automatically reduce the working current of LED lights during the rare time of pedestrians at night, saving electricity and saving the configuration of battery panels. proportion.

(4) The controller is waterproof. Most of the controllers are installed on the base of the light pole. Especially in the rainy season, it is easy to enter the water. Therefore, the controller must choose a fully waterproof controller to extend the life of the system and reduce maintenance costs.

(5) In addition to the above power-saving functions, the controller should also pay attention to the protection function of the battery and other components. A controller with a trickle charging mode can protect the battery well, increase the battery life, and set up a controller. When under-voltage protection value, try to adjust the under-voltage protection value to ≥ 11.1V to prevent over-discharge of the battery. Over-charge and over-discharge of the battery will reduce the service life.

2. How to choose the solar panel 

First of all, we need to determine the photoelectric conversion rate of solar panels (conversion rate = power/area). What is closely related to this parameter is the panel. There are two types of monocrystalline silicon and polycrystalline silicon. Generally speaking, the conversion rate of polycrystalline silicon is usually about 14%. , The highest can only reach 19%, while the conversion rate of single crystal silicon can be as low as 17% and as high as 24%.

In terms of conversion rate alone, it is naturally better to choose solar panels with monocrystalline silicon panels, but the production cost of such panels is higher than that of polycrystalline silicon panels, so the unit price will be more expensive.

You can choose according to your needs when choosing; In addition, the formula for the conversion rate is that at the same power, the smaller the panel area, the higher the conversion rate.

A well-maintained solar street light can generally be used for more than 25 years, and if it is not properly maintained, it may have been used for two or three or even one or two years. Solar street light maintenance first talks about the maintenance of solar panels.

1. Stand and structure pay attention to wind protection: The stand is a support structure for solar panels. Because the solar panels are generally installed at the top of solar street lights, it is easy to cause top-heavy weight, and the solar energy is at high altitude, and it is easy to receive the constant impact of wind. If it is tilted or distorted, it may cause insufficient sunlight radiation and damage to the solar panel due to torsion.

2. The dust-proof surface of the solar panel: The solar panel generally has a service life of 25-30 years, but poor maintenance may reduce its life. Solar panels are most afraid of dust because dust will reduce the rate of sunlight acceptance, resulting in low power generation efficiency. Under normal circumstances, rainwater under natural conditions can help to clean, but for places with less rainfall and heavy wind and dust, you must pay attention to cleaning the dust on solar panels;

3, solar panels pay attention to hail and lightning strikes: Secondly, hail and lightning strikes threaten solar panels. Current solar street lights have anti-lightning functions and can withstand hail strikes in a certain range, but for areas, with more thunderstorms or extremes The situation still needs to be checked frequently, and it will still need to be checked after the increasing hailstorm.

3. How to choose a solar led street light battery

Good solar street lights must ensure sufficient lighting time and lighting brightness. To achieve this, the requirements for batteries are naturally not low. Currently, there are mainly two types of lead-acid batteries (gel batteries) and lithium iron phosphate batteries on the market. Traditional lead-acid batteries have stable voltages, are relatively cheap, and are relatively easy to maintain. However, such batteries have low specific energy, short life, and require frequent maintenance.

The rapid development of lithium iron phosphate batteries has obvious advantages in terms of discharge depth and charging time. The applicable temperature is as low as -45 ℃, and the application environment area is more extensive. Its life can reach 7 ~ 8 years, and it is more worry-free to use.

In addition, the volume and weight of lithium iron phosphate batteries are smaller than lead-acid batteries. It is the only choice. All the lithium iron phosphate batteries used in solar street lights from Nanlai have a long lighting time and sufficient brightness.

In short, although the solar street light is good, there will always be some fake and shoddy products on the market, which will cause trouble in the use process. When you choose it, you must examine it from various aspects. The configuration of the above three aspects must be the focus.
