Abstract: 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.

Abstract: A system includes a photovoltaic module including at least one solar cell with electrical bussing, an encapsulant encapsulating the at least one solar cell and having a first surface with a first opening, and a frontsheet juxtaposed with the first surface of the encapsulant. The frontsheet includes a second opening extending from a first surface to a second surface thereof. The second opening of the frontsheet is in fluid communication with the first opening of the encapsulant. The electrical bussing is positioned in the first opening. An electrical wire is connected to the electrical bussing through the first and second openings. A cover is attached to the frontsheet and covers one end of the electrical wire and the first and second openings.

Abstract: A cable passthrough includes a first layer having a first edge and an aperture, and a second layer overlapping the first layer. The passthrough is configured to be installed on a roof deck, such that the aperture is configured to align with an aperture formed within the roof deck. The passthrough is configured to receive at least one cable having a first end and a second end. The second end of the cable is capable of extending outwardly from the first edge of the first layer and the first edge of the second layer of the passthrough. The cable is configured to be positioned intermediate the first layer and the second layer.

Abstract: This disclosure describes methods and apparatus for assembly a roofing structure that incorporates photovoltaic modules as shingles of the roofing structure. A sidelap is used to both establish consistent spacing between the solar shingles and prevent water passing between adjacent shingles from collecting beneath the solar shingles by guiding the water passing through the solar shingles and redirecting the water down-roof. In some embodiments, the sidelaps can have additional functionality. For example, a sidelap can include tabs configured to interact with lateral securing features positioned on downward-facing surfaces of the solar roofing modules to help keep the lateral sides of the photovoltaic modules from pulling away from the roofing structure during severe weather conditions. The sidelap could also include means for attaching a wire clip to one end of the sidelap.
