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 solar shingle having a substrate positioned beneath an upper material layer and at least one photovoltaic cell coupled to the substrate. A first terminal can be electrically coupled to the at least one photovoltaic cell and positioned adjacent to a first sidewall of the solar shingle, and a second terminal can be electrically coupled to the at least one photovoltaic cell and positioned adjacent to a second sidewall of the solar shingle. An upper surface of the upper material layer can have one or more recesses positioned between the first sidewall and the second sidewall and adjacent to the at least one photovoltaic cell. Further, the upper surface can have a variety of imparted surface characteristics, among other aesthetics and coloring, that can provide the solar shingle with outwardly appearance that is at least similar to traditional, non-solar shingles.

Building integrated photovoltaic (BIPV) systems provide for solar panel arrays that can be aesthetically pleasing to an observer. BIPV systems can be incorporated as part of roof surfaces as built into the structure of the roof, particularly as photovoltaic modules having the appearance of a plurality of roofing tiles that each have photovoltaic cells. Each photovoltaic module may include a metal backer, photovoltaic cells, and light transmissive top sheets adhered to both the metal backer and the photovoltaic cells. BIPV systems can also include non-photovoltaic modules that appear similar to photovoltaic modules, but do not collect solar energy.

A mount assembly is provided for mounting a structure to a roof having a top surface. The mount includes a flashing including an aperture; a bracket including a first portion and a second portion, the first portion having an opening and a countersink extending around the opening, the second portion extending at an angle away from the flashing, the second portion including a slot configured to be coupled to the structure; a fastener extending through the aperture and through the opening of the bracket; and a seal extending around the aperture and positioned between the flashing and the first portion of the bracket, the seal engaging the countersink of the bracket and being compressed against the flashing.

The present disclosure relates to a system for mounting solar panel tiles (or other tiles/panels) over a roof (surface). The system includes mounting frames provided with holes at the bottom for fixing them parallelly over the roof. Bolting members and overhang members are attached to two opposite sides of the tiles to form a tile assembly. The bolting members and overhang members of the tile assembly are provided with a set of holes to allow coupling of the tile assembly between two adjacent mounting frames using bolt/screws. Further, sealing agents are provided on the edges of the tiles as well as the tile assemblies, thereby making the system aesthetically pleasing and leakproof. Another set of vents are provided on the base frames, to allow cables to pass through them, and provide proper ventilation beneath the tiles.

A roof integrated photovoltaic (RIPV) system has a plurality of solar tiles that are mounted to a roof. The tiles may be mounted using a metal batten and hanger system or some other attachment system. Each tile has an electrical edge junction extending rearwardly from its top edge. The edge junction is coextensive with or contains the plane of the solar tile and may be slightly thicker than the solar tile. Sockets on opposed ends of the edge junction receive plugs of electrical cables for interconnecting the array of solar tiles together electrically. The edge junctions provide for a low profile installation that mimics the appearance of a traditional roofing tile such as a slate tile. The slightly thicker edge junctions may raise solar tiles of one course above the surfaces of solar tiles of a next lower course to provide ventilation for the RIPV array and to provide accommodating space for system wiring.

A tile replacement flashing is used with a tile hook. A bottom tile replacement flashing is shaped for placement on a lower portion of a location where a tile is removed from a roof. A top tile replacement flashing is shaped for placement on an upper portion of a location where the tile is removed from the roof. The top tile replacement flashing includes an elevated region at a lower portion of the top tile replacement flashing, the elevated region. The bottom tile replacement flashing is shaped so that after attachment of the bottom tile replacement flashing on the roof, the tile hook can be attached to a rafter of the roof, the attached tile hook extending over an upper portion of the bottom tile replacement flashing and having a portion that, past the upper portion of the bottom tile replacement flashing, extends upwards. The top tile replacement flashing is shaped so that after attachment of the top tile replacement flashing on the roof, at least part of the elevated region of the top tile replacement flashing extends over the bottom tile replacement flashing. A height of the elevated region is sufficient to allow room for the tile hook to extend over the bottom tile replacement flashing and under the elevated region of top tile replacement flashing.

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.

Some embodiments of the present disclosure relate to a roofing system. In some embodiments, the roofing system comprises at least one steep slope roof substrate having a first region. In some embodiments, the first region comprises a plurality of shingles. In some embodiments, each of the plurality of shingles comprises at least one antimicrobial agent. In some embodiments, the at least one steep slope roof substrate also comprises a second region. In some embodiments, the second region comprises an antimicrobial scavenger layer that is configured to receive runoff from the first region of the steep slope roof substrate. In some embodiments, the runoff comprises an initial concentration of at least one antimicrobial agent and water. In some embodiments, the antimicrobial scavenger layer is configured to capture the at least one antimicrobial agent so as to reduce the initial concentration of the at least one antimicrobial agent in the runoff.
