The present invention provides a horizontal single-axis tracking photovoltaic support with double-sided power generation, suitable for installing a double-sided PV module with a toward-sun light absorption surface and a backward-sun light absorption surface, including: an upright post and a torque tube disposed on the upright post, the torque tube capable of being rotated around the upright post under the action of a driving device, a plurality of groups of crossbeams are disposed along a lengthwise direction of the torque tube, and the double-sided PV module is disposed on each group of the crossbeams, a light-reflecting-panel support is disposed at the torque tube, and a light-reflecting panel is disposed on the light-reflecting-panel support. The light-reflecting panel reflects sunlight onto the backward-sun light absorption surface, and an angle between the plane where the light-reflecting panel is located and the plane where the double-sided PV module is located is an acute angle.

Mounting components of photovoltaic (PV) modules and PV module assemblies are described, including PV module couplings and PV module mounting chassis. In an example, a PV module includes a PV module coupling having a toe portion extending from a PV module frame, and a PV module mounting chassis includes a toe slot to receive the toe. The toe and toe slot construction allows for the PV module frame to be assembled to the PV module mounting chassis without using tools, and thus, permits a PV module assembly to be quickly constructed during installation of a PV module system. Furthermore, the toe and toe slot construction accommodates thermal expansion and other environmental loads seen after installation, while providing a grounding connection for the PV module assembly.

A support assembly for mounting photovoltaic modules on a support surface and a mounting system including the same are disclosed herein. The support assembly may comprise a the body portion including a base portion and at least one upright support member coupled to the base portion, the at least one upright support member comprising an integrally formed ballast tray slot in one side thereof for receiving an upturned edge of a ballast tray; and at least one clamp subassembly coupled to the at least one upright support member of the body portion, the at least one clamp subassembly configured to be coupled to one or more photovoltaic modules. In addition to a plurality of support assemblies, the mounting system may further comprise at least one ballast tray support bracket, the ballast tray support bracket supporting a portion of a ballast tray on the support surface.

The invention relates to a stacking spacer for a photovoltaic module frame, to a photovoltaic module frame, and to a tracking device assembly for said photovoltaic module frame and stacking spacer. The stacking spacer comprises a main body extending in a longitudinal direction, a connecting member, extending in said longitudinal direction and protruding from said main body, adapted for being inserted at least one lateral profile groove of said photovoltaic module frame and two opposed support members, arranged on respective opposed longitudinal sides of said main body, extending in said longitudinal direction, wherein the two opposed support members have complementary forms, whereby at least two stacking spacers can be securely stacked on top of each other.

A structural support block cooperates with a cone-shaped protrusion in a roof flashing. The support block and protrusion have a through-hole allowing a fastener to secure the support block and flashing to a roof. Cooperation of the support block and the cone-shaped protrusion in the roof flashing diverts water, particularly on sloped surfaces.

A system and method of providing, assembling and maintaining floating rows and/or arrays of photovoltaic solar panels and terrestrial or elevated based rows and/or arrays of photovoltaic solar panels.

An integral, monolithic mounting bracket supports a corner of a photovoltaic module. The bracket includes a ballast tray for holding one or more ballast blocks, and includes a plurality of monolithic support legs that are disposed at acute angles from a plane of the ballast tray and that are integral with the ballast tray. The bracket can be manufactured by stamping at least two identical sections of metal from the sheet and then bending-up each section on its remaining uncut fourth side into a near-vertical position, so that each bent-up section forms a monolithic support leg.
