A system includes a plurality of photovoltaic shingles installed on a roof deck, each of the shingles having a first layer including a head lap portion, and a second layer including at least one solar cell. A first photovoltaic shingle overlays at least a part of the head lap portion of a second photovoltaic shingle. The system includes at least one wireway installed proximate to a first end of at least the first photovoltaic shingle.

A system includes a plurality of roofing shingles installed on a roof deck. Each of the roofing shingles includes first and second ends, first and second edges, a head lap, a reveal portion, a first side lap at the first end, and a second side lap at the second end. The second side lap includes a first surface, which has an adhesive. The first side lap of a first one of the roofing shingles overlays and is attached to the second side lap of a second one of the roofing shingles to form a sealed portion between the head lap of the first one of the roofing shingles and the head lap of the second one of the roofing shingles.

A system includes a photovoltaic module having photovoltaic cells, each having a width, and a roofing shingle having an exposure zone and a headlap zone. A plurality of slots extends from the exposure zone to the headlap zone and define tooth portions. A first one of the tooth portions has a first side defined by a first slot and a second side defined by a second slot adjacent to the first slot. The first tooth portion has a first width that is the photovoltaic cell width multiplied by a first positive integer. A second tooth portion has a first side defined by a third slot and a second side defined by a fourth slot adjacent to the third slot. The second tooth portion has a second width that is the photovoltaic cell width multiplied by a second positive integer different than the first positive integer.

A microbial inhibiting system for angled asphalt roofs. The system includes copper-based strips along the ridge of the roof, wherein the proximal edges of the copper-based strips are operatively associated between a ridge vent and a portion of the upper roof. A distal end of the copper-based strips may provide windshear bends to keep the whole system in place during high winds. Once installed onto an asphalt roof, the present invention is adapted so that rainwater is directed over the copper-base members of the system, causing a chemical reaction therewith, wherein the resulting chemical will wash away along the roofing membrane, removing any mold, algae, and moss as the chemically infused rainwater rolls down the roof.

A building material-integrated solar cell module (5) includes a solar cell panel (11), a cushioning member (13) disposed at a back side of the solar cell panel (11), a base plate (9) formed of an incombustible material and supporting the cushioning member (13), and a cable (35) drawn from the back side of the solar cell panel (11) and wired on a front side of the base plate (9).

A first plurality of roofing shingles installed in a first plurality of rows on a roof deck, and a second plurality of roofing shingles installed in a second plurality of rows. An edge of one of the second roofing shingles in each of the second rows is offset from the edge of another one of the second roofing shingles in another adjacent one of the second rows. An edge of a first photovoltaic shingle is juxtaposed with the edge of a first roofing shingle of the second roofing shingles in a first row of the second rows. The edge of at least another photovoltaic shingle in at least one of another row of the second rows is substantially aligned with the edge of the first photovoltaic shingle. An additional roofing shingle is installed intermediate one of the second roofing shingles and one of the photovoltaic shingles.

A system includes a plurality of photovoltaic shingles installed on a roof deck, each of the shingles having a first layer including a head lap portion, and a second layer including at least one solar cell. A first photovoltaic shingle overlays at least a part of the head lap portion of a second photovoltaic shingle. The system includes at least one wireway installed proximate to a first end of at least the first photovoltaic shingle.

A roof system for forming a roof includes a first layer positioned over a substrate, the first layer including a translucent material adapted to be exposed to weather, and a second layer positioned between the first layer and the substrate. The second layer is a decorative layer with decorative features such as, for example, an image, design, color, pattern, picture, fabric, or combinations thereof. The decorative features of the second layer are visible through the first layer.

A system includes a plurality of photovoltaic modules, each having a mat with an edge and a spacer with an edge, the edge of the mat being attached to the edge of the spacer. The spacer includes a plurality of support members and a solar module mounted to the support members. Each of the support members includes a ledge. The solar module and the ledge form a space therebetween. The space is sized and shaped to receive an edge of a solar module of another of the photovoltaic modules. The spacer of one of the photovoltaic modules overlays the mat of another of the photovoltaic modules.

A system includes a plurality of roofing shingles installed on a roof deck. Each of the roofing shingles includes first and second ends, first and second edges, a head lap, a reveal portion, a first side lap at the first end, and a second side lap at the second end. The second side lap includes a first surface, which has an adhesive. The first side lap of a first one of the roofing shingles overlays and is attached to the second side lap of a second one of the roofing shingles to form a sealed portion between the head lap of the first one of the roofing shingles and the head lap of the second one of the roofing shingles.
