The disclosure discloses a flat-plate water-heating photovoltaic/thermal module and a production process thereof. The flat-plate water-heating photovoltaic/thermal module includes a frame, wherein the lower surface of the frame is provided with a heat preservation back plate, the upper surface of the frame is sequentially laminated with a glass cover plate, a first photovoltaic cell laminating adhesive, a photovoltaic cell slice, a second photovoltaic cell laminating adhesive, a transparent back plate, a third photovoltaic cell laminating adhesive and a heat absorbing component from top to bottom, and a heat preservation cavity is formed between the heat preservation back plate and the heat absorption part.

A method is disclosed for installing a solar cell module, which enables easy installation of a solar cell module on a rack, and also enables a worker to install a solar cell module without climbing on the roof. A solar cell module is installed on a rack mounted on a roof. The solar cell module includes a frame formed of a material containing a resin. The rack includes multiple rails each having a groove, and the grooves of a pair of the rails are disposed to be opposed to each other. The method of this invention comprises the steps of fitting the frame of the solar cell module into the groove such that the solar cell module is retained by the pair of the rails, and fixing the solar cell module to the pair of the rails to prevent the solar cell module from falling out of the grooves.

A photovoltaic element is provided that comprises a photovoltaic converter panel and at least one mounting arrangement. The photovoltaic converter panel defines a front surface adapted to receive solar impinging light and defines a back surface opposing the front surface. The at least one mounting arrangement is mounted to the back surface of the photovoltaic converter panel by a glue. Furthermore, a mounted surface is provided that comprises at least two such photovoltaic elements.

A mounting assembly for securing fixtures to a mounting structure may include a first fastener, a washer, a mounting bracket, and second fastener. The first fastener may be coupled to the mounting structure through a mounting aperture. The washer may be disposed around shaft of the first fastener between a head of the first fastener and the mounting surface. The mounting bracket may be disposed on top of the first fastener. The second fastener may be disposed through the mounting bracket and coupled to head of the first fastener. The washer may be a sealing washer that dispenses liquid sealant under compressive force to moisture-proof the securement of the first fastener to the mounting surface.

Embodiments of the present disclosure are related to solar module mounting systems. A system may include an adhesion sheet configured to be secured to a roof of a structure via an adhesive. The system may further include at least one clamp configured for securing at least one solar module to the adhesion sheet.

A method for forming a solar panel can include attaching one or more tacking pads to one or both of a first surface of a first solar panel subassembly and a second surface of a second solar panel subassembly. The method further includes dispensing an adhesive onto at least one of the first and second surfaces. The first and second surfaces are placed in contact with the one or more tacking pads, thereby tacking the first and second solar panel subassemblies together, during which the first and second surfaces contact the adhesive, thereby decreasing a thickness and increasing a surface area of the adhesive. Subsequently, the adhesive is cured. The tacking pad(s) maintain fixed alignment of the solar panel subassemblies during curing of the adhesive, and establish a bond line of the adhesive.

A mounting assembly for securing fixtures to a mounting structure may include a first fastener, a washer, a mounting bracket, and second fastener. The first fastener may be coupled to the mounting structure through a mounting aperture. The washer may be disposed around shaft of the first fastener between a head of the first fastener and the mounting surface. The mounting bracket may be disposed on top of the first fastener. The second fastener may be disposed through the mounting bracket and coupled to head of the first fastener. The washer may be a sealing washer that dispenses liquid sealant under compressive force to moisture-proof the securement of the first fastener to the mounting surface.

Embodiments of the present disclosure are related to solar module mounting systems. A system may include an adhesion sheet configured to be secured to a roof of a structure via an adhesive. The system may further include at least one clamp configured for securing at least one solar module to the adhesion sheet. Other embodiments are related to methods of attaching one or more solar modules to a structure.

An apparatus and method for connecting solar panels to a roof system surface. The solar panels can be formed flexible or non-flexible solar panels that are at least partially attached to a roofing surface by use of a fastener.

A non-invasive roof attachment system for attaching structures to residential and commercial roofs without the use of penetrations to roofing shingles and sealing layers is described. The attachment system includes vertical and lateral array stays to attach roof mounted systems such as solar panels. The non-slip attachment system also allows for the quick removal of such roof mounted systems rapidly and without the need for repair of penetrations. The non-slip attachment system uses, among other things, an array-stay retainer comprising a vertical member and a horizontal member. A high friction foam polymer padding may further secure the array stays to the roof.
