A solar power system is a clean alternative source of electrical power by converting sunlight  into electricity. The electricity generated can be either stored or used directly, fed back into grid line or combined with one or more other electricity generators or more renewable energy source. Solar power system is very reliable and clean source of electricity that can suit a wide range of applications such as residence, industry, agriculture, livestock, etc.
 
The system is composed of Solar Panel(s) that converts sunlight into DC electricity. Charge Controller that regulates the voltage and current coming from the solar panels going to battery and prevents battery overcharging and prolongs the battery life. Rechargeable Battery which stores energy for supplying to electrical loads when there is a demand. An Inverter to convert DC output of solar panels or wind turbine into a clean AC current for AC loads or fed back into the grid line. In pure DC loads an inverter is not necessary. DC loads may be connected directly to the charge controller. Correct sizing of these components according to power demand must be considered in designing a solar power system.
