The present disclosure is directed to an energy management system that allows leveraging DC energy at user premises. The system allows for use of local or remote DC energy generated by photovoltaic modules or a battery pack. The system comprises a premises electricity network interface arranged to deliver and draw energy to and from a premises electricity network; a premises energy measurement module arranged to measure the amount of energy required by the premises electricity network; a DC energy input arranged to receive energy from one or more DC energy sources; and an energy analytics module arranged to receive data from the energy measurement module and, based on the received data, calculate an amount of energy to be delivered to the premises electricity network via the premises electricity network interface.

Solar trackers that may be advantageously employed on sloped and/or variable terrain to rotate solar panels to track motion of the sun across the sky include bearing assemblies and other mechanical features configured to address mechanical challenges posed by the sloped and/or variable terrain that might otherwise prevent or complicate use of solar trackers on such terrain.

Single-piece hinged-clamps employed used in assemblies used to mount solar power modules to surface installation are disclosed. In some embodiments, a clamp with a right portion with a right notch having a right platform, a left portion with a left notch having a left platform, and a base portion with a flexible hinge is disclosed. The left portion also includes a threaded aperture extending downwardly from the left platform. In some embodiments, a method of securing a component with the clamp is disclosed in which a right member of a component is inserted into a right notch of a clamp, an applied force imparts movement of a left notch away from the right notch, and a buildup of potential energy in the flexible hinge during the application of the force moves the left notch in the opposite direction to engage the left member of the component.

A mounting assembly includes a rail configured to support a photovoltaic module. The rail includes a first slot, a second slot, and a web extending between the first slot and the second slot. The web being offset from a plane extending along an outer surface of the rail, so as to form a recess in the second side of the rail. The mount assembly further includes a clip configured to be secured to the rail and to a secondary structure. The clip includes a base having a flange extending from an end of the base, and an arm extending from the base in a second direction opposite the first direction, the flange being inserted in the second slot when the clip is secured to the rail and the secondary structure and at least a portion of the arm abuts the recess of the rail when the clip is secured to the rail.

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 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.
