Photovoltaic energy (PV), or solar electric, is electricity generated by solar panels. A solar electric system consists of an array of panels that generate DC electricity, an inverter that converts the DC current to a usable AC electricity, and optionally, a battery to store unused energy. A solar electric system produces electricity with no noise, no air pollution, and no moving parts while using a clean, renewable resource — the sun. It will lower or offset, altogether, your reliance on the grid.
