The solar light lamp has a simple working principle, and the solar cell is made by using the photovoltaic effect principle. During the day, the solar panel receives solar radiation energy and is converted into electric energy output, and is stored in the battery through the charge and discharge controller, and the illumination gradually decreases to about 101ux at night. The open circuit voltage of the solar panel is about 4.5V. After the charge and discharge controller detects this voltage value, the battery is discharged to the lamp cap. After the battery is discharged for 8.5 hours, the charge and discharge control operation and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery.
Solar lights are electric lights that are converted into solar energy by solar panels. During the day, even on a cloudy day, this solar generator (solar panel) can also collect and store solar energy. As a safe and environmentally friendly new light, solar lights have received increasing attention.
