Solar PV system includes different components that should be selected according to your system type, site location and applications. The major components for solar PV system are solar charge controller, inverter, battery bank, auxiliary energy sources and loads (appliances).
PV module – converts sunlight into DC electricity.
Solar charge controller – regulates the voltage and current coming from the PV panels going to battery and prevents battery overcharging and prolongs the battery life.
Inverter – converts DC output of PV panels or wind turbine into a clean AC current for AC appliances or fed back into grid line.Battery – stores energy for supplying to electrical appliances when there is a demand.Load – is electrical appliances that connected to solar PV system such as lights, radio, TV, computer, refrigerator, etc.
Auxiliary energy sources – is diesel generator or other renewable energy sources.
