The components are:
❖ The PV panel which is a semiconductor that converts sunlight directly into electricity.
❖ The charge controller manages the power going into the battery from the solar panels
and protects the battery from overcharging or over discharging.
❖ The inverter converts the direct current (DC) power that the solar panel generate into
alternating current (AC) power that is used in homes and businesses.
❖ The battery stores excess power for later use and during the night and on cloudy days.
