What should we do if solar power is insufficient, long rainy and cloud season, the area with insufficient at high latitude?
Then Solar-grid complementary street light can work well for this condition.
Solar-grid complementary street light need to connect a set of power cable to the electrical power grid, and a transformer will be involved to convert AC electricity to the suitable DC electricity.
It will not upload solar power to the electrical grid. It just switch to the electricity power grid when a long or rainy day occurs.
Less affected by the bad weather(rainy and cloudy) and environment.
Low requirements for battery and battery box.
