Photovoltaic (PV) is one of the most promising and prominent techniques for electricity generation based on solar energy. It is expected to play a dominant role in providing future global electricity demand.
The photovoltaic (PV) solar system is made up of a total of three components: (I) photovoltaic cells or solar arrays, (II) the system's overall equilibrium, and (III) the load. Installing photovoltaic panels, which give clean, green electricity, is one of the most important advantages because it offers significant cost savings.
