Roof shingles that contain photovoltaic cells that are used to generate electricity for the home and are designed to look like conventional asphalt/fiberglass or architectural roof shingles. The photovoltaic shingles could be the size of the standard shingle that take the place of a number of conventional shingles in a row or strip, semi-rigid containing solar cells that are more like conventional shingles or use a film of solar cells that match conventional shingles in flexibility and size. The photovoltaic shingles produce electricity in the form of direct current, which is converted to alternating current using a solar inverter unit. The wiring for the photovoltaic shingles is run through the roof decking to the solar inverter. The shingles are installed in an overlapping pattern and manner just like standard conventional asphalt/fiberglass or architectural roof shingles.
Included in cost: Photovoltaic roof shingles, roof felt, DC/AC solar power inverter, fuses, combiner panel board, safety switches, conduit and wiring to power grid at service panel, feeder wire, connection and activation of photovoltaic shingle array, flashing, gutters, downspouts and installation labor. Roof joists/framing and sheathing costs are included in the report under "Framing".
