Rooftop photovoltaic solar systems and methods for installing interconnection wiring for photovoltaic solar systems. Cabling systems can include cable support stands secured underneath shingles. Cabling systems can include molded rubber raceways mounted using raceway clips secured underneath shingles.

A mounting system includes a mounting device. The mounting device includes an internal cavity defined in a side of the mounting device, a first sealant aperture defined in the mounting device and opening into the internal cavity, a second sealant aperture defined in the mounting device and opening into the internal cavity, the first sealant aperture and the second sealant aperture being in fluid communication when the mounting device is placed on a surface for use, and a fastener aperture defined through the internal cavity. The mounting system further includes a coupling bracket including a bottom portion, an underside surface of which is correspondingly shaped in conformance with a shape of an outer surface of a central portion of the mounting device so as to be accommodated thereon when in use, and a fastener to couple the mounting device and the coupling bracket together via the fastener aperture.

A universal mounting system for supporting a plurality of photovoltaic modules on a sloped support surface, such as a sloped roof, is disclosed herein. The universal mounting system may include one or more support surface attachment devices, each support surface attachment device configured to attach one or more photovoltaic modules to a support surface; and one or more module coupling devices, each module coupling device configured to couple a plurality of photovoltaic modules to one another.

A clamp includes a mount, a connector, and a fastener. The mount has a slot and a channel. The connector attaches to the mount and is transitionable between a first position and a second position in which a solar panel module is securable to the mount. The connector has a post at least partially disposed in the channel and which traverses within the channel between the first position and the second position of the connector. The fastener is disposed at least partially in the slot for attaching the connector to the mount. The fastener tightens to secure the solar panel module to the mount.

A junction box comprising a base configured to mount to a roof, the base including an enclosed bottom, an open end opposite the enclosed bottom, a first side extending from the enclosed bottom to the open end, a second side opposite of the first side, a third side extending from the first side to the second side, and a fourth side opposite the third side, a wall extending from the first side to the second, a high point disposed along the wall, the high point having an angle within a range of 90 degrees and 180 degrees, a lid sized to seal against and hingedly connect to the base, and a flashing that extends from a portion of the first side of the base, from a portion of the second side of the base, and from the wall, in a direction away from the base.

An attachment bracket apparatus includes a base and a flange extending vertically from the base. A central axis extends along the length of the base. A first hole is disposed along the central axis of the base and in the first side of the base. A second hole is disposed along the central axis of the base and in the second side of the base. One or more third holes are disposed on the first side of the base, and one or more fourth holes are disposed on the second side of the base. At least the one or more third holes, respectively, are positioned offset from the central axis and are further offset from each other, respectively, in a direction that is perpendicular to a direction of extension of the central axis.

A ballast that supports solar panel modules. The ballast includes a cavity, a first port, and a second port. The first port is fluidly connected to the cavity and is configured to receive a flowable substance. The second port fluidly connects to the cavity and is configured to interconnect the cavity with an additional cavity of an additional ballast. The cavity is fillable with the flowable substance to provide weight for securing the solar panel modules to a mounting surface.

A clamping mechanism includes a first fastener and a second fastener. The second fastener includes a head having a first rib with a first serration, a second rib with a second serration, a third rib with a third serration, and a fourth rib with a fourth serration. The first rib extends a first length and the first serration extends a second length that is less than the first length. The second rib extends a third length and the second serration extends a fourth length that is less than the third length. The third rib extends a fifth length and the third serration extends a sixth length that is less than the fifth length. The fourth rib extends a seventh length and the fourth serration extends an eighth length that is less than the seventh length. The second fastener includes a body coupled to the first fastener.

A mounting system includes a base, a post coupled to the base, a stanchion having a passageway that rotatably couples about the post, a locking mechanism removably coupled to the base and configured to engage with the stanchion to prevent rotation of the stanchion, a cap having an opening, and a fastener disposed through the opening and into the passageway.
