Disclosed are a folding module, a photovoltaic mounting structure, and mounting method thereof. The folding module includes a panel having front and back sides, two support blocks disposed on the back side of the panel adjacent to the two sides, two support members each hingedly connected with one of the support blocks such that the support members foldable and rotatable about the respective hinges. The photovoltaic mounting structure includes a plurality of photovoltaic modules, each module having front and back sides, each side attached with a securing block connector and a hook connector, both connectors further attached to a bracket assembly. The bracket assembly of the front side of the structure is rotatable about the securing block connector and the hook connector of the front side, and the bracket assembly on the back side is rotatable about the securing block connector and the hook connector of the back side.

A pole mounted dual axis solar tracking apparatus has a main mounting member [13] in a fixed primary north-south axis which is inclined to accommodate geographical latitude and a cross arm [16] fixed to the main mounting member and defining a secondary east-west axis. A support frame [15] for PV panels, solar reflectors etc. is pivoted to the cross arm to enable the support frame to tilt over the secondary east-west axis. The apparatus is highly efficient due to its ability to sweep through the shape of two conjoined cones. The apparatus operates with close to the efficiency of a dual axis tracker but with the simplicity of a single axis tracker.

A supporting rack for a solar panel with a framework mountable on a surface such as a roof, this framework including two elongate runners extending parallel to each other and a cross-member extending between and connecting the two runners. Upper and lower clamp assemblies detachably and adjustably mount the solar panel on top of the framework so that the panel extends at an acute angle to the plane of the runners. There are two front clamp assemblies, each mountable on a respective runner and clamped to a front edge of the solar panel. A clevis pin connection pivotally connects the clamping mechanism to its respective runner. Two upper, rear clamp assemblies each have an adjustable J-clamp member and a back plate. After installation of the rack, the panel is pivotable from an operating position at an acute angle to the runners to a greater angle to facilitate maintenance or repair.

Disclosed are systems, methods, and devices related to fixed and transportable structures and vehicles utilizing the integration of solar and wind technologies for generation of electricity. The system generates electricity using solar panels (and/or solar thermal units) and wind turbines, stores and converts electricity, and can be located in various locations either as fixed or portable embodiments including on land, on water, underwater, air and space and may also be housed in a structure to provide electricity for various facilities and uses.
