• Advantages and disadvantages of solar street lights and city circuit lights

  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. The investment cost will be recovered in 1-3 years and will benefit in the long term. 3 there are safety risks Solar lights are ultra-low voltage products, which are safe and reliable in operation. 4 main components of solar street light The service life of solar panels is 25 ye

• What are the factors related to the price of solar street lights?

  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
