(Summary description)Everyone is familiar with solar street lights and can be seen everywhere on the road. The country is also vigorously advocating the use of solar resources. So how do solar street lights save energy? The following is an introduction to energy saving of solar street lights. 　　 1. Energy saving and environmental protection 　　Solar street lights are mainly composed of four sectors: photovoltaic modules, light-emitting diodes, solar cells and controllers. Photovoltaic modules absorb light during the day, convert solar energy into electrical energy, store it in solar cells, and discharge and illuminate at night when it gets dark. 　　 In general, when the weather is fine, it only takes 4 hours to fully charge under strong light. After each charge is completed, it can be guaranteed for more than 5 days, and it can work normally if it lasts for 3 days in rainy or cloudy weather. In short, in cities with increasing energy consumption, urban electricity consumption has become too important: industrial electricity and household electricity consumption have remained high in recent years and have been increasing year by year. Is common. If solar street lights can be widely used, it will greatly reduce the electrical power of the city. 　　 2. Energy-saving economy First of all, each solar street lamp is a relatively independent system. There is no need to embed cables or excavate the road during installation and construction, which saves a considerable part of manpower, material resources and installation costs; besides, it consumes electricity, and an ordinary street lamp lights up all day. The lamp time is about 6 hours, the power consumption is about 2 degrees, and the electricity bill is more than 300 yuan a year. If an urban area is calculated based on 300 street lights, it costs nearly 100,000 yuan a year. Solar street lights can be saved. 　　 According to reports, 50 million new outdoor lights are added every year across the country. If solar lights can account for one-thousandth, it can save the country hundreds of millions of kilowatt-hours of electricity a year.
