Major system components Solar PV system contains different components that should be selected according to your system type, site location and applications. The main components for solar system are solar charge controller, inverter, battery bank, auxiliary energy sources and loads (appliances). • PV module – It can convert sunlight into DC electricity. • Solar charge controller – It regulates the voltage and current coming from the solar panels going to battery and prevents battery overcharging and increases the battery life. • Inverter – It is use to convert DC output of solar panels into a clean AC current for AC appliances or fed back into grid line. • Battery –It is use to store energy for supplying to electrical appliances when there is a demand. • Load –It is electrical appliances that connected to solar system such as lights, radio, TV, computer, refrigerator, etc. • Auxiliary energy sources – They are diesel generator or other renewable energy sources. Solar PV system sizing: 1. Determine power consumption demands The first step is to design a solar PV system is to find out the total power and energy consumption by all loads that need to be supplied by the solar PV system as follows: 1.1 Calculate total Watt hours per day for each device used. Add the Watt hours needed for all devices together to get the total Watt-hours per day which must be provided to the devices. 1.2 Calculate total Watt-hours per day needed from the PV modules. Multiply the total
