Solar lighting

With the continuous consumption of energy and the continuous deterioration of the environment, the development and utilization of renewable energy resources are of great significance in ensuring energy security, protecting the ecological environment, and achieving sustainable development. Solar lighting has developed rapidly and its devices cover almost the entire lighting field. Demand for solar lighting products is increasing day by day, and the requirements for product quality are also increasing.

Solar lighting uses solar energy as its energy source to achieve photoelectric conversion through solar cells. During the day, it uses batteries to accumulate and store electrical energy. At night, the controller supplies power to the electric light source to achieve the required functional lighting.

(1) Direct power supply

The electricity generated by the solar panel is stored in the battery, and the battery supplies power directly to the light source.

(2) Indirect power supply (inverter power supply) The inverter converts DC power into AC power, and then supplies power to the light source. Inverter power supply increases power loss by 10% to 20%.
