Principle of Solar Lawn Lamp

Solar lawn lamp composition

It consists of solar cells (receiving light to generate electricity for battery charging), charge and discharge controller (to control the charging and discharging state of the battery), battery (storage and power supply for the light source), light source (load) and light pole.

Working principle

Solar cells receive sunlight during the day to generate electricity (photovoltaic)

Issued by the electricity and then charge the battery through the charge and discharge controller. Full of automatic power off, there will be no overcharging situation

At night, the battery supplies power to the light source (load) through the charge/discharge controller. The controller will automatically control the working time of the light source and the discharge state of the battery according to the setting or usage. The controller it will not let the battery over discharge, which will lead to shorten the life of the battery.
