3. 5 m solar street light

With the rapid development of photovoltaic technology, solar street lamps in the urban and rural areas soon got the promotion and application, especially in the absence of grid rural received considerable attention, and a success. At the same time, in the city of many have been equipped with a power line

with the rapid development of photovoltaic technology, solar street lights in urban and rural areas, especially not in rural areas has been widely promotion and application of the power grid, and achieved success. At the same time, solar street light has been installed in many laid on urban roads of the wire, but the road is different from the rural roads. If they are in the same way design, on the one hand, they can't meet the requirements of city road lighting, on the other hand, they also cause the waste of resources. As a result, commercial power complementary solar street light is a good way to solve this situation. Mains complementary solar led street light by the solar panels, solar street light controller, storage battery, lighting lamps and lanterns, the console and the power line communication. Its advantage is very obvious. The following small series will introduce the advantages: first, city street lamp two-way power supply can be greatly reduced cost, lower energy consumption, in line with the green environmental protection idea. Second, 365 daylighting. Because of the battery capacity and power panel design problem, the ordinary solar street light can't keep a lot of rain light and in the morning light. With complementary, on the other hand, the utility of solar led street lamp can automatically switch to the power supply in rainy day, 365 days, every day is bright. Third, improve the service life of the solar cell. Mains complementary solar energy street lamp can restrict the solar cell cycles, prolong the service life of batteries. Fourth, do not need to set up other communication line, the cost is low, communication error rate is low, less susceptible to interference, and can be used for large-scale network control. Above is the advantages of solar street lamps and complementary power supply business. When use, must adjust measures to local conditions, reasonable use, reasonable collocation, can play a good lighting effect
