The present disclosure relates generally to roofing systems, for example, suitable for covering the roof of a house or other building. The present disclosure relates more particularly to a roofing system that includes a plurality of riser blocks disposed on a support surface. The riser blocks include a group that is aligned in a row. A batten extends along the row and is supported by the group of riser blocks. The batten includes a first clip portion. A group of roofing panels is disposed along the row and is supported by the batten. Further, each of the roofing panels of the group includes a front surface, a rear surface, and a second clip portion extending from the rear surface. The second clip portion is configured to engage the first clip portion of the batten so as to secure the roofing panels to the batten.

A method may include positioning one or more PV module mounting devices along a length of a structural component. The method may include specifying one or more parameters related to fastening the PV module mounting devices to the structural component, the one or more parameters indicating a spacing between the PV module mounting devices. The method may include fastening, by an automated attachment equipment, the PV module mounting devices to the structural component based on the specified parameters and moving the PV module mounting devices fastened to the structural component to an assembly platform.

A tile system comprises at least two tiles and at least one elongate support. Each tile is generally rectangular in shape and has a first edge, and a second edge, the second edge being generally opposite the first edge. Each elongate support has an attachment portion and a support portion. Proximate the first edge each tile is provided with a groove, the groove being configured to receive the support portion of one of the elongate supports and a portion of an adjacent tile proximate its second edge.

Surface mount assembly for mounting to a solar panel frame to an installation surface is disclosed. In some embodiments, a surface mount assembly includes a base and an enclosure. The base includes a lower member and an upper member. The lower member could include a brace, a center aperture extending through the lower and upper members for receiving a fastener to facilitate the mounting to a solar panel frame; the upper member could include a hub from which a plurality of arms may extend. The mount enclosure could include a chamber with a chamber aperture for receiving a fastener from the surface mount, a post support extending upward from the chamber and forming a post aperture for receiving a post, and a horizontal member with one or more sealant grooves extending horizontal outward from the chamber.

A solar heat exchanger for heating water which includes an array of tubes, an injection molded manifold there being connections between each tube in the array and the manifold which are over molded to seal the tubes to the manifold.

In various representative aspects, an assembly for securing a solar panel rail and rail-less support structures to a shingle roof. More specifically, the apparatus includes a connection bracket and flashing device for use in installing solar panel rail support structures. The connection bracket is secured to the flashing device by placing it over various embodiments of a cone element that is embedded within the flashing and secured using a tightening mechanism such as a bolt, screw, or other fastener. A solar panel rail support guide can be connected to a generally U-shaped connection on the top of the bracket. The apparatus also offers an improved means to cover the penetration point on the flashing to protect it and prevent water from leaking into the roof as well as an improved way to install the apparatus over existing products. Various embodiments of the bracket and flashing provided as well.

An improved frame for a solar panel that facilitates securing a solar panel into the frame, and facilitates connection of the frame to a mount assembly for a solar array.

Systems and methods for mounting solar panels include a curb assembly coupled to a top surface of a roof. An end of a solar panel rests on a portion of the assembly. An astragal is located with a portion of the astragal extending over the edge of the solar panel. A fastener is engaged through the astragal and the curb assembly such that a portion of the astragal contacts and compressively engages the top surface of the supported solar panel edge, whereby the solar panel is mounted to the roof. Moreover, systems and methods cleaning solar panels of a solar panel system installed on an exterior surface are also described.

A bonding clamp includes a top bracket including opposing side walls defining a channel therebetween. The top bracket has an aperture through a central portion thereof. The top bracket is shaped to receive a first photovoltaic (“PV”) module on a first side and a second PV module on a second side. A bottom bracket includes a body and a pair of top flanges extending vertically from a top surface of the body. The pair of top flanges are spaced apart from each other. The bottom bracket also includes anti-rotation flanges extending from a bottom surface of body. A fastening mechanism fastens the top bracket in a fixed position with respect to the bottom bracket.

A bracket includes a base configured to be mounted to a mounting surface and a flange extending from the base and positioned to bisect the base thereby forming a first side and a second side of the base. The base includes a first hole disposed along a central axis of the base and in the first side of the base, a second hole disposed along the central axis of the base and in the second side of the base, and one or more divots formed in a top side of the base and disposed on the first side of the base. Fasteners are inserted through the first hole and the second hole when the bracket is secured to a first mounting structure. Furthermore, fasteners are inserted through the first hole, the second hole, and are drilled through the one or more divots when the bracket is secured to a second mounting structure.
