A solar shingle having a substrate positioned beneath an upper material layer and at least one photovoltaic cell coupled to the substrate. A first terminal can be electrically coupled to the at least one photovoltaic cell and positioned adjacent to a first sidewall of the solar shingle, and a second terminal can be electrically coupled to the at least one photovoltaic cell and positioned adjacent to a second sidewall of the solar shingle. An upper surface of the upper material layer can have one or more recesses positioned between the first sidewall and the second sidewall and adjacent to the at least one photovoltaic cell. Further, the upper surface can have a variety of imparted surface characteristics, among other aesthetics and coloring, that can provide the solar shingle with outwardly appearance that is at least similar to traditional, non-solar shingles.

A system for sealing a terminated solar cable, the system including: a solar cable; a connector terminating the solar cable, the connector including a locking feature; and a plug including a locking feature. When the locking feature of the plug engages the locking feature of the connector to lock the plug and the connector in a locked state, the solar cable is sealed to provide safety from voltage and protection from dust and liquid.

In some implementations, the power plant may include an array having 200 or more modules. In addition, the array may have conterminous modules. Arrays may include modules having a contact point that rests on the ground or a contact surface of one or more structures. In some implementations, 90% of the power-plant arrays have 800 or more modules. In some plants, the ground supports 90 percent of the conterminous modules. In some plants, neither the plants nor the arrays do not contain stowing functionality or extreme dampening functionality.

A grounding system, structured to ground a number of cables supported by a support assembly, includes a multi-function line assembly and a number of conductive mounting assemblies. Each conductive mounting assembly is structured to be coupled to the multi-function line and to a conductive pile.

The invention relates to a frame for photovoltaic modules into which connection sockets and module electronics can be integrated so as to be easily accessible and which is simultaneously used as a guide system for connection cables.

A solar cell louver assembly includes: a plurality of solar cell module units having a solar cell panel part, with a pair of terminal portions provided on both end parts, a pair of first electrode terminals electrically connected to the respective terminal portions, and a pair of first caps mounted on the solar cell panel part to surround the respective first electrode terminals; second electrode terminals electrically connected to the first electrode terminals, and second caps accommodating the second electrode terminals and having mounted thereon the first caps; a frame unit having an inner frame such that the second caps are mounted rotatably in the length direction, and an outer frame surrounding the inner frame; and a connector unit between the inner and outer frames and having a pair of third electrode terminals electrically connecting the second electrode terminals of adjacent module units when mounted in the frame unit.

Various implementations described herein are directed to a methods and apparatuses for disconnecting, by a device, elements at certain parts of an electrical system. The method may include measuring operational parameters at certain locations within the system and/or receiving messages from control devices indicating a potentially unsafe condition, disconnecting and/or short-circuiting system elements in response, and reconnection the system elements when it is safe to do so. Certain embodiments relate to methods and apparatuses for providing operational power to safety switches during different modes of system operation.
