    In Depth Comparison: Solar Street Light VS. Traditional Street Light

    What is the difference between traditional and Solar street light Prices? Clodesun will analyze the cost of the two types of street lights clearly this time. In order to solve this problem, our company’s senior engineer team collected various aspects of knowledge to analyze the cost of traditional street lighting systems and solar street lights.

    If you do a quick research of the market, you will find that because the US government and world leaders are promoting renewable energy, solar street lights have rapidly become popular and grow rapidly in the past 7 years. More and more countries now advocate the use of solar renewable energy for lighting instead of traditional lighting.

    Following is the analysis of the cost of the two types of street lights.

     

    What is the price of traditional street light?

    Traditional street lighting obtains electricity by connecting to a standard power grid. The average cost of traditional street lamps (including lighting fixtures, poles, and lamp holders) is $120 per lamp. Although the cost of lamps is lower, traditional street lights need to be connected to the grid, which requires slotting and underground wiring. If added the labor costs for trenching and wiring, the cost per meter for consumers in this process is about US$40.

    Then, the average cost of traditional lighting slotting and connection will be about 3,200 US dollars, which is much higher than the price of solar street lights. Moreover, traditional solar street lights are not energy-saving. You can imagine how much coal is consumed for 12 hours a day.

    What is the price of solar street lights?

    Solar street lights obtain electricity through the process of solar panels absorbing solar energy, which converts light into usable voltage. Solar street lights (solar panels, batteries, controllers, inverters, lamp heads) require advanced technology, so the price is higher, on average about 330 US dollars per light.

    Solar street lights do not need to be connected to the power grid, they are separated from the main grid system and can be installed in remote locations. So clients can avoid the long and expensive process of slotting and wiring. Therefore, the total cost of the solar street lighting system is greatly reduced.

    The price of solar street lights makes customers feel more expensive than traditional street lights initially, but when you carefully study their total cost details. You will find that the biggest difference between the price of traditional lights and solar lights is trenching, installation, maintenance, and electrical bill costs rather than just the cost of street lighting.

     

    Conclusion

    When comparing the total cost of traditional street lighting and solar street lighting, it is clear to distinguish who is the winner. Overall, the cost of solar street lights in 5 years is about 4,800 US dollars, while the cost of traditional street lights is as high as 8,800 US dollars, which is due to the cost of trenching and installation.

    As above, this is only the cost for one street light. If one project needs to install 100 sets of street lights, and 200 sets of street lights, obviously, solar street lights are more cost-effective.

    If there is a road that needs to be installed with a lighting system, will you choose traditional street lights or solar integrated street lights? If you just think that the cost of the product, maybe solar street lights is more expensive, you are wrong. Taking all the costs together, it is obvious that solar lights can win the cost battle of street lights. If you want to learn more about solar street lights, please follow the Clodesun blog.

    solar street light quality in China

    Solar street light price in Nigeria

    Since 2016, ClodeSun has become a top Solar Street Light Supplier in Nigeria.

    Nigeria has the world’s largest market for solar-led street lights, and the solar street light price in Nigeria competition is very fierce these years.

    Many Nigerian traders import all-in-one solar street lights from China, Jiangsu, Shenzhen, Zhongshan, and Yangzhou, There is a very large solar street light market in Lagos Nigeria, which specializes in sells solar street lights.

    1. solar street light price in Nigeria survey

    Nigeria is the world’s largest market for solar street lights because Nigeria is the largest economic country in Africa, but Nigeria’s electricity is very scarce, and the power supply is very backward. According to the calculations of Nigeria’s power department, about 55% of Nigeria’s residents have no electricity available. It has become one of the main problems hindering the economic development of Nigeria, so the market for solar street lights in Nigeria is very large.

    These dealers are very sensitive to the price of solar street lights. There are also many solar street light engineering companies. Their solar street light projects are cover all over Africa. They pay more attention to the quality of solar street lights but not just the low price.

    split solar street light

    2. solar street light price in Nigeria analysis

    There are two types of solar street lights, split solar street lights and integrated solar street lights. Now 90% of the market needs are split solar street lights. Integrated solar street lights account for about 10%, but the demand for integrated street lights every year All is increasing and may reach 20% in the next few years.

    The price of integrated solar street lights is relatively higher than that of split solar street lights. Because integrated solar street lights are of better quality and easier to install, they are more and more popular with consumers. In other countries, most of them choose to use split solar street lights, but in Nigeria, more and more customers choose to use integrated solar street lights, so integrated street lights are getting better and better in the Nigerian market.

    However, consumers in Nigeria prefer solar street lights at relatively low prices. They are not particularly concerned about the quality of solar street lights. Nigeria’s civilian market is very sensitive to the price of solar street lights.

    Therefore, many traders are working in China in order to obtain higher profits. Zhongshan, Yangzhou, Jiangsu, and other places import very cheap solar street lights. In fact, the quality of these solar street lights is very poor. Usually, the solar street lights do not light up in less than half a year, and their life expectancy will not exceed two years.

    3. why the solar street light price in Nigeria is very cheap

    Because Nigerian customers want to buy solar street lights at the lowest price, solar street light manufacturers just have very low profits. Therefore, in order to get higher profits, solar street light manufacturers have to reduce the configuration of solar street lights or use very poor materials.

    Although the price of solar street light products is very cheap, the quality is very poor. Many Nigerian consumers don’t know that they just see the appearance of solar street lights and they all look the same, so they are more willing to buy cheap solar street lights, which leads to very chaos in the industry, Even many consumers think that the quality of solar street lights is very bad, and they are no longer willing to buy solar street lights.

    This idea is actually wrong. In fact, the technology of solar street lights is very mature now. A good quality solar street light can last for more than five years, and some can last for 8-10 years, but usually, the price of such high-quality solar street lights is not very cheap.

    We have several customers from Nigerian engineering companies. When they find us, they don’t ask for the price of solar street lights but visit our factory first. After we exchange some technical parameters, they will come to our production area. , Test the parameters and quality of our solar panels, lithium batteries, controllers, and then talk about the price of solar street lights.

    solar street lights price

    After customers have tested the accessories and materials of our solar street lights, they know that we are using the best materials, so they are not very sensitive to the price, but the quality requirements are indeed very high, and the after-sales service requirements are also particularly high.

    Conclusion:
    Although the solar street light market in Nigeria is very large, the price of solar street lights is in a mess. most solar street lights in Nigeria in very poor quality, and the price is very low.

    clodesun hope that Nigerian customers will change their views and care more about the quality of solar street lights not just be careful about the lower price of the product in the future.

      solar street light pole

      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, and 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 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.

      solar new clean energy

            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:

      clodesun was established in 2013. Headquartered in Shenzhen, it is a high-tech enterprise in China. It is a new energy high-tech company integrating R&D, production, and sales. CLOSE attaches great importance to the development of LED all-in-one solar street lighting technology.

      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:


       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.

      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.



       Li-ion lithium battery

      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.
