How much effect can the energy-saving benefits of solar street lights play?1

1. Each solar street light is a relatively independent lighting system. There is no need to embed cables during installation and construction, and there is no need to excavate the road. This saves considerable manpower, material resources and installation costs, and also prevents wire aging. The potential safety hazards are very popular in areas where electricity is relatively tight and the power supply construction time is long; 　　2, an ordinary street lamp has a lighting time of about 10 hours a day, and its power consumption is about 2 degrees, a year It needs nearly 1,000 yuan in electricity bills, and this is only the cost of one lamp, and these costs can be saved by using solar street lights. After a one-time investment, you can save 30% in one year; 　　3. Compared with ordinary street lights, solar street lights using LED light sources have a longer service life. The general set life is 15 years, of which only 3-5 years It takes time to replace the battery and maintain other components, which can save a lot of money than installing ordinary street lights; 　　The annual landscape lighting in Beijing requires about 100-200 million kWh of electricity. If solar lighting equipment is used in conjunction with the city electricity, One-tenth of the original power consumption can be used for landscape lighting. At the same time, solar energy equipment receives light to accumulate energy during the peak power consumption of the country, and powers the lighting source at night when the power consumption is low. To a certain extent, it is also Played a role in peak regulation of electricity. Among the 50 million new outdoor lighting lamps nationwide each year, if solar street lamps can account for one-thousandth, it can save the country nearly 700 million kilowatt-hours of electricity a year, which is equivalent to sending a 100,000-kilowatt power station to the country. In the future development, solar energy and other lighting equipment using natural resources will be further popularized, saving more energy for the country.
