What is the principle of solar mains complementary lighting system?

The solar mains complementary lighting system is an intelligent lighting solution that combines solar power and mains dual power supply modes. During the day, the solar panels absorb sunlight and convert it into electrical energy, which is stored in the battery. At night, clean energy is used for power supply. When it rains continuously or the battery is low, the system will automatically switch to mains power mode to ensure that the lights continue to light up and the lighting is not interrupted due to weather. This design is not only energy-saving and environmentally friendly, but can also cope with complex weather changes. It is especially suitable for courtyards, rural roads, outdoor squares and other scenes that require long-term stable lighting.
