The use of renewable energy reduces the use of primary fossil-based energy sources, thereby reducing the associated environmental footprints. Using photovoltaic cells to generate electricity can be an effective method for the generation of onsite electricity. PV cells are sources of renewable energy that convert the energy directly into electricity using semiconductors. PV cells produce a direct current, which needs to be converted to an alternating current before it can be used in buildings. The common technique is to store direct current from PV cells in batteries and change it to an alternating current using an inverter. The major advantage of an alternating current created by the inverter is that the alternating current is compatible with city utility grid.  If the local PV system can generate additional electricity, the excess electricity can be transferred to the main utility grid and sold to the city electric provider, specifically when the city grid experiences high demand from customers during certain times of the day.
