The new rural road lighting project in Heping Village, Leizhou City, with a total road design of about 2,000 meters. Two factors were considered in the early stage: First, the Heping village belongs to the township area, which is different from the centralized energy supply of the city. The energy use is scattered, and the ordinary street lamp infrastructure cost is high; the second is that Leizhou is located at 20°26′-21°11′ north latitude, south of the Tropic of Cancer, with low latitude, sufficient sunshine and abundant heat. The average annual sunshine is 2003.6 hours, and total solar radiation is 108-117 calories per year. CM2. Therefore, in the design of road lighting schemes, SL series integrated solar street lamps were selected according to local conditions. According to road planning requirements, a total of 50 pcs SL-1A integrated solar street lamps were used.
