What are the six core advantages of solar street lights? I will introduce to you, the main contents are as follows: 1. Environmental protection Compared with traditional street lights, solar street lights mainly rely on sunlight during the day to convert into electricity and release electricity for lighting at night. No other energy sources are used at all, and solar energy is recognized as the most environmentally friendly energy source in the world. Therefore, the pollution index of solar street lights is almost 0 in terms of pollution. The only thing that can pollute is the battery. However, under normal circumstances, the probability of a battery polluting the environment is very low, and it will be recycled when it cannot be used. 2. Security City circuit lights generally use 220v or 380v voltage for power supply and lighting. If the city circuit lights are damaged or malfunctions, there will be a risk of leakage or fire. The 12-24v low-voltage power supply used by solar street lights has stable voltage and reliable operation without any safety hazards. 3. Energy saving The energy supply of solar street light manufacturers is sunlight. Solar energy is an inexhaustible energy source for us humans. Ordinary city circuit lights consume a lot of live energy in order to supply night lighting because of the AC power used by them. 4. Long-term investment is low From the current point of view, if the price of buying city circuit lights is much lower than the price of solar street lights, the secondary or tertiary investment of city electricity will be very large, such as control boxes, cables, engineering, operating electricity costs, maintenance, etc., while solar street lights A one-time investment, no maintenance cost, and the cost can be recovered in about 2 years.

Preface: Driven by social and economic development, my country's street lamp service facilities have been further improved, and the corresponding street lamp maintenance work has also increased. Street lights play an indispensable role in people`s daily lives. Providing basic lighting services for people on the road at night is also an important part of the basic service system of modern cities. But if you want to better play its service role, you must focus on doing Good maintenance and maintenance work, take corresponding measures based on the actual situation of the region, formulate practical and reliable maintenance plans in accordance with unified standards, improve the overall maintenance management efficiency and quality, and reduce unnecessary problems. Existing problems and solutions: Causes of failure and maintenance measures when street lights are off and voltage is normal 1) Street lights are naturally aging. During the long-term use of the street lamp, the electrode emission material will gradually decrease. With the prolonged use of the street lamp, it will eventually be exhausted, and this material will remain in the arc tube, and these residual impurities will continue to deflate. The starting voltage of the street lamp will be greatly increased, making it more and more difficult to start the street lamp. If it is serious, it will not be able to start. This will bring inconvenience to people`s travel. When solving this problem, the best way is Replace with new street lights. 2) The outer glass shell of the street lamp is damaged or leaking. Street lights are mostly continuously illuminated at night, and the external environment is changeable. In case of bad weather, it will inevitably affect the normal performance of the street lights. This requires a glass shell outside the street lights. For example, a high-pressure sodium lamp, if it is damaged or leaks

The difference between monocrystalline and polycrystalline solar panels
2021 / 01 / 14
1. The appearance of the module. From the top of the appearance, the four corners of the monocrystalline silicon cell are arc-shaped and there is no pattern on the surface. The four corners of the polycrystalline silicon cell are square corners, and the surface has patterns like ice flowers. 2 2. For users, there is not much difference between monocrystalline silicon cells and polycrystalline silicon cells in the use of components. Their life and stability are very good. The average conversion efficiency of monocrystalline silicon cells is higher than that of polycrystalline silicon, but the current price is higher than that of polycrystalline silicon. 3 3. In the module manufacturing process, polycrystalline cells have fewer production process steps than monocrystalline cells. Therefore, the energy consumed in the manufacturing process of polycrystalline silicon solar cells is slightly less than that of monocrystalline silicon solar cells, but the power generation of monocrystalline solar cells is higher. Calculating the energy consumption ratio is not much different. Comparison of monocrystalline photovoltaic modules and polycrystalline photovoltaic modules 1) Looking at the history, the application of monocrystalline photovoltaic panels was earlier than that of polycrystalline photovoltaic panels. Monocrystalline is the big brother, and polycrystalline is the younger brother, but the younger brother developed faster later. 2) Depending on the amount, the application of polysilicon in power stations is much higher than that of monocrystalline silicon, with monocrystalline silicon accounting for 30% and polycrystalline silicon accounting for 70%. 3) Looking at the appearance, the monocrystalline silicon is dark blue, almost black, the polycrystalline silicon is sky blue, and the color is bright, the single crystal cell is rounded at four corners, and the polycrystalline cell is square. 4) Looking at the conversion ra

2021 / 01 / 13
City circuit lights 1. The installation and operation procedures are complicated, and cables need to be laid. A large number of basic works such as excavation of cable trenches, laying of hidden pipes, threading in the pipes, and backfilling must be carried out. And for a long time installation and debugging, the terrain and wiring requirements are complicated, and the labor and auxiliary materials are expensive. 2. The cost of electricity is high, and it is necessary to maintain or replace the line and other configurations for a long time, and the maintenance cost is increasing year by year. 3. There are hidden safety hazards, due to the construction quality, the transformation of landscape engineering, the aging of materials, the abnormal power supply, and the conflict between water and electricity pipelines. 4. The average service life of city circuit lights is about 10,000 hours, and the longer the service life, the greater the degree of pipeline aging. 5. The larger the scale, the higher the related costs for the installation of municipal circuit lights, and the total investment will be higher than that of solar street lights. In addition, the annual loss of cable theft cannot be estimated. Solar street light 1 install simple There is no need to lay complicated lines, just a cement base, fixed with stainless steel screws. 2Free of electricity charges Solar street lights are a one-time investment with no maintenance cost.

2021 / 01 / 12
The price of solar street lights is determined by the configuration of solar street lights. Solar street lights are assembled products and are divided into nine major components: solar panels, solar batteries, controllers, LEDs, lamps, poles, battery boxes, cables, and embedded The price of solar street light is composed of the unit price of nine major components, so the price of solar street light has a great relationship with what kind of accessories the solar street light chooses; today I will analyze it from the perspective of solar panels and batteries a bit: 1. Solar panels for the price of solar street lights: Solar panels are currently divided into monocrystalline silicon panels and polycrystalline silicon panels on the market. The price difference is about 4 to 5 cents per watt. The price of monocrystalline is higher, and the price of polycrystalline It's cheaper. What is the difference between single crystal and polycrystal? 1. In appearance, the monocrystalline solar panels are black with chamfers; the polycrystalline solar panels are bluish with no chamfers; 2. In terms of conversion efficiency, the conversion efficiency of monocrystalline solar panels is higher than that of polycrystalline solar panels, 17%-18% for monocrystalline solar panels and 16%-17% for polycrystalline solar panels; 3. The strong light effect of monocrystalline solar panels is better, while the weak light effect of polycrystalline solar panels is better; To sum up, if you choose different solar panels, the price of the whole set of solar street lights will be different, but the current solar street lamp applications, polysilicon solar panels are enough for solar street light power generation systems, there is no need to use monocrystalline silicon Solar panels, at the s
Talking about the three stages of LED street lamp market development
2021 / 01 / 11
1. The LED lamp replacement acceptance stage This stage refers to the early development of LED products, which mainly reflects the characteristics of high efficiency (low energy) and long life. Because of the high price, LED lighting products are mainly used in the commercial market at this stage. In view of the customer's acceptance process, the first is the transition and acceptance of the use habits and appearance. According to the comparison with traditional light sources, under energy-saving use conditions, the price of long-life LED lighting products is relatively high and easy to be accepted by the market, especially in commercial occasions. Many solar street light manufacturers use quality and price advantages as a means of competition. 2. LED street lights in the utility model stage Based on the above stages, LED lighting products have been recognized and accepted by the market. LED lighting products featuring environmental protection, small size, and reliability are gradually emerging. Then a series of LED lighting products are completely different from traditional light source products in many ways. The lighting industry will have a larger and broader development space. Its wide variety is more suitable for people's work and life. Then, many solar street lamp manufacturers take advantage of design and application, and competitive means. Third, the intelligent control stage of LED street lights The process that the LED lighting industry will go through, from product manufacturing to product design, and to provide overall solutions. The LED lighting industry also shows high controllability characteristics. The LED street light products and intelligent control system will bring high-quality services to humans, from homes t
Talking about the five traps to pay attention to when purchasing solar street lights
2021 / 01 / 09
First, the core of counterfeit chips and low-end chips LED lamps is the chip, which directly determines the performance of the lamp! However, some unscrupulous manufacturers take advantage of customers' unprofessionalism and use low-cost chips from the perspective of cost, which causes customers to buy low-quality products at a high unit price, causing direct economic losses and causing serious quality risks to LED lamps. Second, configure virtual labels and exaggerate configuration parameters The fierceness of solar street lamps is also accompanied by the reduction of price and profit. The fierce competition has also led to many solar street lamp manufacturers beginning to cut corners and false standard product parameters, such as the wattage of light source, the wattage of solar panels, the capacity of batteries, and even the use of solar street light poles. The materials are all in problems. Of course, this is also caused by customers' repeated price comparisons and low prices. It is also related to the practices of some manufacturers. Third, poor heat dissipation design and unreasonable configuration In terms of heat dissipation design, every time the PN junction temperature of the LED chip increases by 10 degrees, the life of the semiconductor device will be reduced by multiples. Due to the high brightness requirements of LED solar street lights, the use environment is relatively harsh, if the heat dissipation is not solved well, it will quickly cause LED aging and reduce stability. In addition, unreasonable configuration often leads to specific usage conditions that fall short of expectations. Fourth, the copper wire pretending to be gold wire and the controller problem Many LED manufacturers try to develop materials such as copper alloy, gold-clad silver alloy wire, and silver alloy wire to repla

1. The ability of solar street lights to save electricity during the discharge process: solar street lights are lighting equipment that solar panels absorb solar energy and then convert them into electrical energy. To ensure the normal operation of the lighting equipment, it is necessary to use electrical energy efficiently to reduce the loss of discharge, and then achieve energy saving The role of consumption reduction! 2. The solar battery has the ability to store electric energy: the electric energy converted by the solar battery panel, if there is no battery storage, then these capital will be spoiled. Therefore, the solar battery must have a satisfactory storage capacity and be compatible with the conversion of solar panels Combination, and the higher the storage capacity of the solar battery, the better; 3. The ability of solar panels to convert solar energy into electrical energy per unit time. The conversion capacity is related to the size of solar panels. Assuming that temporary rainy days occur in a certain area, relatively large solar panels should be used;
The problem of solar street light installation cannot be ignored

With the improvement of economic development, solar street lighting has become an integral part of beautifying the urban landscape. Therefore, in order to ensure the solar street light project, street light appliance suppliers and installers should actively intervene in the solar road lighting project in advance. The following points should be paid attention to in the street light installation: 1. In rock formations and weathered stone areas, scattered grounding and segmented grounding are difficult to meet the requirements. You can consider the galvanized flat steel and other conductors to be connected according to the design requirements. The connection should be reliable. At the same time, appropriate protective treatment and pre-embedded The foundation is reliably connected to ensure that each light pole is reliably connected to the ground. The high pole lights in solar street lights are scattered, and they mainly rely on basic grounding. If necessary, use resistance reducing agents to reduce grounding resistance.

Pay special attention to the power grid lines and other lines around the hoisting equipment, as well as the surrounding structures. The hoisting points should be reasonable during hoisting and should be adjusted in time after positioning. 3. Pay attention to the beauty of the solar street light pole after installation. Starting from the foundation construction, the straightness of the lamp position should be controlled based on the main line, and the line shape of the road design should be changed reasonably. The lamp pole should be straight, and the welding seam and access opening should be avoided in the main line direction, and the whole line should be consistent. The inclination of the cantilever of

Solar street lights---As a segment of the photovoltaic industry, it can directly use solar energy to generate energy, save energy and save electricity, and does not require complex and expensive long-distance power transmission cables. It also has many advantages such as automatic operation and voltage safety. In recent years, it has been widely and quickly used to replace traditional street lamps. However, this market segment is experiencing short-term pains. "Solar street lights were dismantled for one year after installation", "A town installed thousands of street lights in June 2015, and the failure rate of the lamps reached 21% after half a year." There are more solar street light projects that force maintenance every year , Resulting in a lot of waste of manpower, material resources and financial funds. For this phenomenon, the main reason is that some products that do not meet the standards are selected, there are no standards, quality inspections, after-sales, etc.... The quality assurance has become an empty talk for several years, and some companies even have a 20-year warranty... Why solar energy So many problems have appeared in the street lighting industry? In the final analysis, it depends on the characteristics of the industry, the product production process in the industry is messy. Most of them are patchwork rather than independent R&D and production, and even many lighting companies do not have factories without certification. These companies often cut corners and shoddy materials in the production process, thus bidding at low prices, causing the industry to proliferate low-quality and low-cost garbage projects. Although solar street lights mainly rely on solar energy to generate electricity during use, which can save a lot of electricity, many projects are often implemented with the hope that they can rely on the electricity saved in later use to recover the cost year
