A solar panel frame waterproof structure, comprising multiple solar panels (1), multiple frames (2), multiple frame bodies (3), and multiple sealing strips (4). Each of the solar panels (1) has upper and lower surfaces (11, 12) and four side edges (13); each of the frames (2) is provided at the side edge of the solar panel (1), and has an upper bonding plate (21) and a lower bonding plate (22); a vertical plate (24) is connected between the upper bonding plate (21) and the lower bonding plate (22); the vertical plate (24) is non-planar, and is provided with at least one protruding portion (241) facing or away from the direction where the vertical plate (24) is bonded to the solar panel (1); a recessed portion (242) is formed at the side opposite to the protruding portion (241); each of the frame bodies (3) is provided below the frame (2) and is fixedly connected to the lower bonding plate (22); each of the sealing strips (4) is provided between the frames (2) of two adjacent solar panels (1), so that upper and lower barriers can be formed between the vertical plates (24) of the two adjacent frames (2) by the sealing strips (4). Thus, better assembly convenience and waterproof effect can be achieved.

A roof-mounting device for covering a roof penetration in a roof includes a base having an open top, an open bottom, and an outer perimeter structure. An internal reservoir of the device is in communication with the open top and the open bottom, and a mount plate is disposed in the internal reservoir extending between opposed ends of the outer perimeter structure. A bore is formed in the mount plate below the top of the base, the bore for receiving a fastener for fastening the mounting device at the roof penetration. When the bore receives the fastener therein, the internal reservoir is unsevered, remaining in communication with the open top and open bottom of the base.

A photovoltaic array comprising: three or more overlapping rows of photovoltaic modules wherein at alternating ends, adjacent rows of photovoltaic modules are interconnected by a row-to-row flashing piece wherein a first row of photovoltaic modules extend a distance beyond a second row of photovoltaic modules and a third row of photovoltaic modules and the second row of photovoltaic modules is in communication with one or more flashing components that extend the second row of photovoltaic modules at least the distance that the first row of photovoltaic modules extend.

A photovoltaic array system comprising: (a) a plurality of photovoltaic components that are configured to be connected together; and (b) one or more alignment features located on at least two of the plurality of photovoltaic components; wherein the one or more alignment features are located in a side edge region of at least one of the plurality of photovoltaic components and in a top edge region of at least one of the plurality of photovoltaic components, and the one or more alignment features indicate when two or more of the plurality of photovoltaic components are aligned relative to each other so that the two or more photovoltaic components can be mated together to form a fixed connection.

A building construction surface element includes a PV-panel and, spaced therefrom, a building construction element including a mounting plate spaced from and facing the backside of the PV-panel and a thermal insulation plate. Spacers define for an interspace between the backside of PV module and the topside of the mounting plate. Building construction surface elements are used to finish building surfaces. As such building surfaces may possibly not be covered by an integer number of the building construction surface elements, dummy building construction surface elements may be provided which do not have a PV module, but whereon a more easily tailorable PV module fake is applied. By combining building construction surface elements with appropriately tailored dummies the building construction surface may be completely covered, thereby providing for a homogeneous optical appearance.

Watertight fastening devices and systems and methods for the employment thereof are disclosed. The disclosed watertight fastening device includes a head, a shank extending away from the head toward a distal end, and a cover extending outwardly and away from the head in the direction of the shank and defining a hollow region between the shank and an inner surface of the cover. The watertight fastening device may be used in conjunction with a solar power installation system that includes a base plate configured to be positioned against an installation surface. The base plate includes an aperture for receiving the shank of the fastener and protrusion surrounding the aperture configured to be received in the hollow region of the fastener, thereby providing an enhanced barrier against moisture reaching the installation surface.

Disclosed are devices and methods for mounting solar panels to a surface. A device for mounting solar panels to a surface comprises a frame configured to be secured to the surface. The frame comprises a retainer comprising a first jaw and a second jaw defining a channel between them for receiving a solar panel, wherein the first jaw adjoins the surface when the frame is secured to the surface.

Embodiments relate to an enhanced method for installing solar roofs by primarily reducing the installation time. The design is for a roofing shingle with an embedded solar module that installs intuitively like normal roofing shingles without special tools, fasteners or alignment. The shingle structure is molded out of low thermal expansion plastic composite and is compatible with commercial photovoltaic modules as well as solar infrared radiation absorbing devices.

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.
