Present invention provides a float capable of suppressing deformation of the synthetic resin body even if internal gas expands and contracts due to environmental temperature change. A float comprises a float body made of a synthetic resin molded in a hollow shape, a projecting portion projecting from the upper surface of the float body and having a vent hole, and a microporous membrane adhered to the outside of the vent hole.

A system for attaching a solar panel to a support, includes a support connector and a solar panel connector, where the support connector includes a U-shaped profile having a lower wall and two side walls, where an upper end of the side walls is bent inwards to provide vertical rails for receiving the panel connector; and the panel connector include a profile having: an upper C-shaped portion configured for receiving a side edge of a solar panel; a lower, upwardly oriented channel portion configured for receiving the vertical rail of the support connector; and at least one box-shaped portion connecting the upper C-shaped portion and the lower channel portion.

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.

An apparatus and method for mounting a solar panel in a solar panel mounting assembly is disclosed. The solar panel mounting assembly includes a mounting bracket and a helical drive, where the mounting bracket is vertically adjustable by the helical drive. The helical drive engages with a stanchion that is variably positioned along a base member that is fixed to a roof.

A system for mounting solar panels on a building may include panel mounting brackets each including a base to be positioned on the building and a vertical extension having a proximal end coupled to the base and a distal end vertically spaced apart from the base. The system may also include interior mounting clamps each including a leg having a proximal end to be coupled to the distal end of the vertical extension of a given panel mounting bracket and a distal end. Each interior mounting clamp may also include a first lateral arm for securing a first solar panel to the given panel mounting bracket, and a second lateral arm for securing a second solar panel to the given panel mounting bracket. The second lateral arm may have a bottom surface positioned vertically above a bottom surface of the first lateral arm along the leg.

Mounting clamps may be utilized to quickly and easily secure solar panel modules relative to mounting rails, which may in turn be secured relative to a mounting surface (e.g., a roof). The mounting clamps may be configured to quickly secure the solar pane modules relative to the mounting rails by tightening a tightening element to pull a clamp element toward the surface of a mounting rail, thereby clamping a portion (e.g., a frame) of a solar panel module between the clamping element and an outer surface of the mounting rail.

A pin comprises a metal body extending along a longitudinal insertion axis (Ox) and has a first and a second end along the longitudinal axis (Ox), an upper face and a lower face opposite the upper face. The pin has two convex portions each having an inclined inner wall and an inclined outer wall, the inclined walls of each convex portion forming a ridge and extending along the longitudinal axis. At least one ridge has on its lower face a protruding blade obtained by cutting and folding the metal body along the longitudinal axis. A concave portion of the pin connects the inner walls of each convex portion via a central surface. The pin has at least one blocking member.

Solar module clips that may be advantageously employed in solar trackers to decrease time and effort in the installation and the alignment of solar modules as well as address mechanical challenges posed by extreme weather events and other forces encountered in the course of use. Alignment may be simplified by tabs on the module clips that secure the solar panels as well as provide a visual marker. Module clips may also include other features, such as any of standoffs, module stops, or pillars for ease of installation and further constraining movement of solar panels.
