How solar lights work

Solar lights are electric lights that are converted into electricity by solar panels. During the day, even on cloudy days, this solar generator (solar panel) can collect and store solar energy. As a safe and environmentally friendly new electric light, solar light has been paid more and more attention.

The working principle of the solar lamp is simple. The solar cell made of the principle of photovoltaic effect. During the day, the solar panel receives the solar radiation energy and converts it into electrical energy for output. It is stored in the battery through the charge and discharge controller. At night, when the illumination is gradually reduced to about 101ux, The open-circuit voltage of the solar panel is about 4.5V. The charge-discharge controller detects this voltage and acts, and the battery discharges the lamp head. After the battery has been discharged for 8.5 hours, the charge and discharge control will act, and the battery will be discharged. The main function of the charge and discharge controller is to protect the battery.
