Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect — the emission of electrons when a material is struck by photons. A solar cell is the basic unit; multiple cells wired together form a solar module (panel), and multiple panels form an array. Solar panels produce DC electricity, which is converted to AC by an inverter for use in the home or export to the grid.

The roof of the duplex has a photovoltaic array that generates solar electricity. See Solar and [Duke Energy](40-Services/Duke Energy.md) for details on the solar service and utility interconnection.
