An atmospheric water generation system absorbs water from an atmospheric air stream into a desiccant flowing along a flow path of a closed desiccant circulation loop. To ensure that the desiccant remains within the closed desiccant circulation loop, the atmospheric water generation system encompasses a membrane-based water extraction device that the desiccant flows through. The desiccant flows through the membrane-based water extraction device on a first side of a membrane, and the membrane separates the desiccant from a water-collection flow. Water absorbed into the desiccant passes from the desiccant, through the porous membrane, and into the water-collection flow, at least in part due to differences in temperature and/or pressure characteristics of the water flow and the desiccant flow. Water collected within the water-collection flow is directed to a storage tank for usage.

A system and method for expedited tile installation are disclosed. The system may include a clamp strip and at least one tile. The clamp strip may be made of conjoined foldable strips. Each strip may include one or more clamps. The clamp strip role may be configured to unroll on a surface. The clamp strip may be adhered to the surface, after unrolling, using one or more fastening mechanisms. The at least one tile may include one or more wedges fixed to a rear side of the at least one tile. Each wedge may be configured to be inserted into the one or more clamp for installing the at least one tile. The one or more clamps and the one or more wedges may be configured to interlock for gripping the at least one tile to the clamp strip.

A first embodiment of a torque tube coupler may include an outer body that includes a first abutting surface and a second abutting surface adjacent to the first abutting surface. Set screws may be inserted into one or more channels of the first abutting surface. Tightening the set screws may force the abutting surfaces away from each other and the outer body to press against an inner surface of a torque tube. Another embodiment of the torque tube coupler may include a central ring sized based on a size of a torque tube. The torque tube coupler may also include a set of fingers that extend away from a first side of the central ring and are shaped to flex radially outward. The torque tube coupler may include a core disposed within the set of fingers that, when drawn towards the central ring, causes the fingers to flex radially outwards.

A mounting system for mounting a solar panel assembly to a base assembly includes a panel support bracket, a base bracket and a clamp configured to exert a compressive force to hold the panel support bracket and the base bracket together. The clamp comprises a V-shaped clamp body that includes a pair of legs that are spring-loaded to oppose an approximation of the legs by an external compressive force. The clamp includes a pair of receiver slots, with each of the pair of receiver slots located on a corresponding one of the pair of legs. The pair of receiver slots collectively provides a clearance to admit the panel support bracket and the base bracket when the legs are compressed together.

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.

A back contact structure of a solar cell, includes: a silicon substrate, the silicon substrate including a back surface including a plurality of recesses disposed at intervals; a plurality of first conductive regions and a plurality of second conductive regions disposed alternately in the plurality of recesses, where each first conductive region includes a first dielectric layer and a first doped region which are disposed successively in the plurality of recesses, and each second conductive region includes a second doped region; a second dielectric layer disposed between the plurality of first conductive regions and the plurality of second conductive regions; and a conductive layer disposed on the plurality of first conductive regions and the plurality of second conductive regions.

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.
