Understand the characteristics of solar street lighting

　　 The so-called solar street lamp is a kind of street lamp that uses solar energy as an energy source. It is not limited by conventional electricity, does not need to drain trenches, and does not consume conventional electrical energy. It can be used as long as it is in a place with sufficient light. Because solar street lights are not affected by conventional energy sources and will not pollute the environment, they are also called green products.　　Solar street lights are generally lighting facilities for roads and parks. But in some areas where the economy is underdeveloped, or lack of conventional energy, solar street lights are also popular. Because solar street lights solve the energy problems in these places according to their own characteristics.　　 In fact, due to the maturity of technology and advanced concepts, solar street lights have also gained a very high penetration rate in developed countries. In countries like the United States, Japan, France and other countries, the use of solar street lights is already very high. But in our country, it is still in its infancy. We expect that solar street lights can be better popularized in China.　　Actually, solar energy can gain such a rapid popularity. In addition to solar street lights, which use sunlight as energy source, they also have many incomparable advantages compared with ordinary lights.　　 First of all, he doesn't need to ditch and bury the wire, and the amount of work is relatively small. Just install a cement base and fix it with stainless steel screws. In addition, because solar street lights are free of electricity charges, they only need to be invested once, and there is no maintenance cost. Generally, the investment cost can be recovered in two to three years and the income can be obtained.　　Furthermore, compared to conventional street lamps, solar street lamps are safer, because they are ultra-low voltage products, so they are safer. The main components of solar street lights, the service life of solar panels is very long, generally around 25 years, so the benefits are relatively large.　　 Finally, the most important point is that because solar street lights are green products, they will not harm the environment and become a new selling point for high-ecological communities for promotion.
