Solar Photovoltaic (PV) is an array of cells that collect energy from the sun and convert it into electricity. These cells are widely known as “solar cells”. PV technology has been around for over 100 years; in the past, its primary purpose has been to provide enough energy for satellites and spacecrafts to orbit the earth. More recently, however, the majority of PV applications have been grid-connected—such as solar farms or building integrated PV (BIPV).
The energy produced by PV systems is 100% green, unlike electricity produced by conventional methods. Approximately 1 car is taken off the road for every year a 5 kW array is producing electricity in the United States.
