Solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current (DC).

The DC Power from the PV cells is then sent to an inverter, where it is converted into alternating current (AC).

The AC Power then travels from the inverter to your electrical panel where it is then available to provide electricity to your home.

Any excess electricity produced by your system feeds back into the utility grid, rolling your meter backwards in the process.

You may be able to reduce your electric bill to zero depending on the size of the solar array installed.  No matter the size of the array, solar is a worthy investment that will reduce your monthly energy bills and contribute to our shared goal of environmental stewardship.
