A method of coupling solar panels to one or more rails via one or more module clamps to form at least a portion of a solar assembly. The method can include positioning a first and second solar panel on at least a first rail, the first and second solar panels being positioned adjacent and defining a slot between the first and second solar panels. The method can further include positioning a module clamp between the first and second solar panels in the slot between the first and second solar panels, the module clamp engaging the first and second solar panels and the first rail. The module clamp can include a bolt and a clamp head.

The present disclosure describes an expandable splice configured for reinforcing a tube of a solar owner system, the splice including a top panel, a bottom panel, a first side panel, a second side panel, and at least one beveled corner panel, wherein the first and second side panels are connected to the top and bottom panels either directly or by the at least one beveled corner panel to form a channel therebetween.

An actuator comprising a bottom plate, a top-plate and one or more hub assembly extending between and rotatably coupling the bottom and top plates. The actuator also includes one or more bellows units disposed between the top plate and bottom plate, the one or more bellows units comprising a first and second inflatable bellows coupled by a web extending between the first and second bellows, the first and second bellows defining respective and separate first and second bellows cavities, with the first bellows of the bellows units disposed on a first side of the bottom plate, and the second bellows of the bellows units disposed on a second side of the bottom plate, opposing the first side, and between the top and bottom plates.

Fixed-tilt solar arrays constructed from screw anchors. In some cases, purlins are attached directly to truss legs. In others, they are attached to truss caps joining the free end of each truss leg. In still further ones, screw anchors are driven in rows and interconnected by a pair of hinged members, one of which provides a mounting plane for solar panels. Each screw anchor may serve as a connection point for the trailing hinged member of the first foundation and the leading hinged member of the next foundation. In still further cases, a hinged truss cap may be used to accommodate different tilt angles with the same foundation.

A bearing assembly of a power generation structure including, a rail; and a housing adapted to support the rail; where the housing includes a fixed housing portion attached to a support beam, and an adjustable housing portion attached to rail, where a low friction material is present at an interface between an exterior surface of rail and an interior surface of the adjustable housing portion, where the adjustable housing portion is capable of self-aligning adjustment of at least a portion of the rail out of alignment with a central axis of the support beam.

An alignment tool for use with a solar panel support rack, configured to allow for the easy and rapid positioning of the support rack into proper alignment to receive solar panels.
