Photovoltaic (PV) systems use solar electric panels to directly convert the sun’s energy into electricity. This conversion of sunlight to electricity occurs without moving parts, is silent and pollution free in its operation.
Most residential PV systems are used in conjunction with utility-supplied power. Power produced from the PV system is sent to the power grid and offsets the cost of electricity that is consumed from the utility.
Most often, PV panels are installed on roofs, but they can also be installed as free-standing units, on a pole on the ground, or even on complex tracking structures that change with the sun’s angle during the day.
