    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.

    Price Breakdown: How Much Do Solar Street Lights Cost?

    Solar street lights have been gaining dramatic popularity in recent years. Solar street lights is a good eco-friendly and renewable alternative lighting solution that captures the hearts of people, particularly those green movement supporters and those who want to sustain and protect the environment they’re living in.

    People purchase different types of solar street lights for a variety of purposes. Some purchase to provide enough light on their house street, backyard, and garden, while others need it for commercial business’ parking lot, public’s general areas, and roadsides.

    Of course, the first question you might have when considering buying from solar street light suppliers is their prices. So today, I am going to shares my professional insights as a solar street light exporter.

    What is a solar street lamp?

    This kind of solar street lamp is generally composed of solar panels and several sets of bulbs or led lights. Most of them are 5 or 6 meters in height.

    The traditional solar street lights in cities are mostly composed of several sets of bulbs and are generally divided into two headlights to illuminate the sidewalk and motor vehicle lanes respectively. The road conditions in rural areas are relatively simple, so the general street lights often only illuminate the motor vehicle lanes.

    Solar street lights are generally purchased in large quantities. Then, what is the wholesale price of solar street lights? Let everyone know!

    Wholesale solar street light price

    What is the wholesale price of solar street lights?

    In fact, due to the different specifications, the price of solar street lights has a wide range. For example, in a wholesale setting, they may only cost 50 US dollars per piece (with regular specifications), or can easily reach 150 US dollars per piece (with higher specifications).

    Compared to solar-powered ones, the price of traditional street lamps is about 100 dollars.

    Example: Prices of 60w Solar Street Light

    Many people asked me how much the price of 60w solar street light with 6000 Lumens recently, 60w solar street lights are the best-hot selling street lights in the market these years. Because 60w solar street lamp not only can be used in solar street light projects but also can be used in civil projects.

    Next, we will introduce the price of 60w solar street lights and their specifications.

    Typical specifications of 60w solar street lights

    Not including shipping, tariffs or other costs, you may pay about US$250/piece for a very high-quality 60w solar street light.  30$ for the maintenance and electricity costs per unit,

    Cost comparison with traditional street lights

    In many places in the world, traditional street lights are getting replaced with solar-powered street lights. Main reason? The long-term cost advantage.

    • Upfront purchase cost: in most cases, solar LED street lights are much more expensive. This is the main reason that most buyers think twice before making a decision.
    • Installation cost: this might be surprising to you, but installing traditional street lights require wiring and underground trenching to connect to grid lines creating enormous additional costs,
    • Maintenance cost: Solar-powered LED street light poles need battery replacement every 5-7 years. Traditional street lights simply can’t compete with that.

    To summarize, solar street light has a much lower lifetime cost. Over 10-year period, traditional street lights installation, maintenance, and electricity cost per unit ranges from U$8,000-12,000 while solar street powered LED light cost is estimated at 4,000-6,000 USD over the same period of time.

    How to buy the best-quality integrated solar street lights?

    This is the doubt of many purchasers. What are the tips for purchasing integrated solar street lights? Next, Belinda will introduce you to the precautions for purchasing high-quality solar street lights.

    1. Battery life: The service life of high-quality solar street lithium iron phosphate batteries can be as long as eight years, and the service life of low-quality batteries is only a few months, half a year, you need to replace the new battery.

    2. Lamp bead brightness: Solar street lights do not mean that the greater the power of the light source, the more manufacturers falsely report the power, or buy low-lumen lamp beads to reduce costs. In fact, to achieve the same brightness, the lower the light source power, the better.

    Power saving, the luminous efficiency of LED light sources of other companies on the market is now 80-100Lm/W, and the light decay is high, the light decay reaches 15%-30% in one year, and the angel eye LED light source uses high-quality LED chips, And the low light attenuation structure and process of the patented technology, the luminous efficiency reaches 130Lm/W, the actual light attenuation is only about 2-3%, and the patented lamp mold can better use the light source.

    3. Resistant to the low-temperature environment:

    Clodesun company equipped with an exclusive patented ultra-low temperature protection device, which can work at -40 ℃, even in high and cold areas.

    all in one solar light

    In order to ensure the working state and efficiency of led solar street lights, it is necessary to consider whether the storage battery can meet the use conditions of solar street lights, and check the use of the storage battery in time. The price of led solar street lights is determined by the materials used and the fineness of the workmanship of the led solar street lights. It needs to be selected before installation.

    Now that the world Internet is very developed, people’s ability to obtain information is becoming easier, so now everyone can understand some things relatively easily with integrated solar street light suppliers. It can be said that in the current solar street light market, everyone now values the quality of integrated solar street lights a lot, but is not so concerned about the price. So the era of seizing the market by fighting the price war has passed. If the quality of the integrated solar street light suppliers is not doing well, then it is likely that consumers will be lost.

    When we buy integrated solar street light products, we must remember to compare over 3 manufacturers, only by comparing you will know which product is good quality, the price is affordable, and the after-sales service is relatively late to improve. For non-professionals, it is impossible to judge the quality of products by appearance, especially for users who lack professional knowledge, so Belinda recommends the buyers buy some samples to test first, samples can prove everything.

    If you care about quality, please respect its price; if what you want is cheap, please don’t assume that there will be good quality! No matter how beautiful the language is, it is a lie! remember forever.

    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.

      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 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 a gel maintenance-free battery and lithium batteries. Gel battery life is normal 2 to 3 years and lithium battery life is normal for 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.

        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.
