A universal adapter for enabling truss foundations to support conventional single-axis trackers. In some cases, the adapter has a main body with an upper portion that presents a standard I-beam interface with pre-drilled holes to interface to a specific single-axis tracker. A pair of connecting portions point down and away from the main body and enable upper leg sections to connect the adapter to a pair of driven screw anchors located below it. The connecting portions may orient the truss so that the rotational axis of the single-axis tracker is aligned with the work point of the truss foundation made from the adapter, upper legs, and driven screw anchors. This will enable to the truss to interface with many different trackers much like conventional plumb-driven H-pile foundations.

Various apparatuses and methods are provided for measuring the likely environmental impact of a particular geographic location on power generation properties of potential solar installations at the particular location. In an example embodiment of one such apparatus, a measurement device is provided. The measurement device includes a base portion comprising a base frame element disposed on a plurality of supporting legs, and a top panel comprising a series of connected members and one or more measurement modules whose planar dimensions are defined by the series of connected members. The top panel is connected to the base portion by a joint such that the top panel can rotate about the joint, and a panel support element is configured to fasten the top panel immovably at a desired degree of rotation in relation to the base 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.

In various embodiments, a mounting system may comprise a downslope rail, an upslope rail, a first clamp and a second clamp. The downslope rail may have a first profile and comprising a downslope face and an upslope shelf. The upslope rail may have a second profile and comprising a downslope shelf and an upslope face. The first clamp may be configured to engage the downslope face and accept the installation of a first end of a solar panel. The second clamp may be configured to engage the upslope face and retain a second end of the solar panel against a downslope shelf

A solar power system can include a rail and a solar module disposed on the rail. A clamp assembly can couple the solar module to the rail. The clamp assembly can have a clamped configuration in which the solar module is secured to the rail and an unclamped configuration. The clamp assembly can comprise an upper clamp member, a lower clamp member coupled to the rail, and a stabilization member mechanically engaging the upper clamp member and the lower clamp member. The stabilization member can prevent rotation of the lower clamp member relative to the rail when the clamp assembly is in the clamped and unclamped configurations. In the unclamped configuration, the stabilization member can be biased such that the upper clamp member is disposed at a sufficient clearance above the rail to permit the insertion of the solar module between the upper clamp member and the rail.
