Abstract: Improved photovoltaic (PV) assemblies for converting solar radiation to electrical energy and methods of installation thereof are disclosed herein. PV arrays comprising a plurality PV modules are also described herein. A PV assembly can comprise at least one PV module having a front side and a back side opposite the front side. A PV module can comprise a plurality of solar cells encapsulated within a PV laminate. In some embodiments, a PV module includes a frame at least partially surrounding the PV laminate. In such embodiments, frame can comprise an outer surface feature. The PV assembly can further comprise at least one spacing device positioned between adjacent PV modules. A spacing device can comprise a spacer body having a predetermined width for defining a predetermined distance or gap between adjacent PV modules.

Abstract: A mounting assembly for securing fixtures to a mounting structure may include a first fastener, a washer, a mounting bracket, and second fastener. The first fastener may be coupled to the mounting structure through a mounting aperture. The washer may be disposed around shaft of the first fastener between a head of the first fastener and the mounting surface. The mounting bracket may be disposed on top of the first fastener. The second fastener may be disposed through the mounting bracket and coupled to head of the first fastener. The washer may be a sealing washer that dispenses liquid sealant under compressive force to moisture-proof the securement of the first fastener to the mounting surface.

Abstract: Photovoltaic (PV) assemblies and electrical connections for interconnecting PV modules to form PV arrays are described herein. The PV assemblies can include angled connector terminals to electrically mate with power connector ports of the PV modules. A power connector port can face a corner of a PV module. The electrical connections of the PV assemblies can simplify cable management and facilitate flexibility in arrangement and interconnection of PV modules and PV arrays.

Abstract: A solar power system may include rails, solar modules, and a plurality of clamps to secure the solar modules to the rails. An end clamp may be partially disposed inside a rail at an end of the rail. The end clamp may secure a solar module to the rail by coupling to the frame of the solar module. The end clamp may include a fastener that may be tightened to engage the end clamp and secure the solar module by holding it on top of the rail. The end clamp may establish an electrical grounding connection between the frames of the solar module and the rail.

Abstract: Improved solar power systems and photovoltaic (PV) assemblies for converting solar radiation to electrical energy, and methods of installation thereof are disclosed herein. A solar power system or PV assembly can comprise a mounting structure and/or a support structure for mounting or supporting PV modules of an array. An electrical conduit or raceway along or across the support structure can transfer power output from the array. A solar power system or PV assembly can further comprise a conduit management system for managing, directing and/or elevating the electrical conduit along a power output pathway above the support surface. A conduit management system can comprise one or more conduit management devices. A conduit management device can comprise a base portion for coupling to the support surface. A conduit management device can further comprise an engagement head for reversibly engaging the electrical conduit.

Abstract: A fixture may be installed on a mounting surface such as a roof of a structure. The fixture may be coupled to round elongated components such as wires, cables, conduits, pipes, or tubes that need to be transitioned from the exterior of the structure on top of the mounting surface to the interior of the structure below the mounting surface by passing through the mounting surface. To prevent moisture such as precipitation from penetrating the mounting surface, a mounting surface transition may be used to transition the round elongated components through the mounting surface. The transition may include compression fittings to establish a moisture barrier around the round elongated components.
