Solar photovoltaic cells are typically mounted on rooftops; these panels are the basic building blocks of a solar energy system. The photovoltaic solar cell is composed of material that is similar to that of a computer microchip. A solar photovoltaic cell is composed of small semiconductor elements that can convert a solar ray into an electron. When these electrons move they are converted by the photovoltaic cells into a DC electrical current.
The DC electrical current is captured by the solar photovoltaic cells and is sent to an DC-to-AC inverter. The DC-to-AC inverter converts the direct electrical current (DC) to an alternating electrical current (AC). This alternating electrical current (AC) reverses direction at regular intervals. The alternating electrical current provides the energy required to supply energy for all of your household needs.
Any surplus current that is not being used by the house can be routed either to the battery backup solar cell pack or back to the community energy grid. The battery backup system provides an extremely reliable system for keeping the lights on when the sun is not shining. Unlike a typical backup battery system that burns propane gas, these batteries are recharged entirely with the clean energy from the sun. During the day your solar panels are not only converting sunlight into electricity, they will also recharge the battery backup system. Typically these batteries can provide uninterrupted electrical operation for up to 12 hours.
