PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs. In order to withstand the outdoors
When solar energy is pumped into a battery, a chemical reaction among the battery components stores the energy. The reaction is reversed when the battery is discharged, allowing current to exit the battery.

In its basic forms, solar PV is a very straightforward proposition. Hook a solar panel up to a DC load and it will run until the sun goes down. Connect solar panels to a grid-tied inverter and, as long as the sun is shining, power will be sent to the utility. It''s all fairly easy — until the sun stops shining.
