  • Patent number: 11764727
    Abstract: A solar system comprises at least one solar panel with a plurality of solar cells. The solar panels include first and second split-circuits to extract electrical energy from the solar panel. The first split-circuit includes solar panel wires that electrically connect, in series, the solar cells of the first split-circuit to extract electrical energy from the solar panel. Similarly, the second split-circuit includes solar panel wires that electrically connect, in series, the solar cells of the second split-circuit to extract electrical energy from the solar panel. The first and second split-circuits are configured to generate a voltage not to exceed a voltage specification, such as a voltage specification of 35 volts.

  • Patent number: 11658606
    Abstract: An expandable and retractable photovoltaic structure includes a base that provides support to permit mounting of the photovoltaic structure solely from the base. Photovoltaic panels are arranged adjacently between the base and a lead element when the photovoltaic structure is in an open configuration. The photovoltaic structure is supported by scissor link mechanisms, coupled to the base at one end and the lead support element at the other end. The scissor link mechanisms consist of scissor links pivotally coupled together to form a moveable successive chain of the scissor links. The photovoltaic panels are attached to the scissor links, via side frames, so that as the lead arm moves away from the base the scissor link mechanisms expand to deploy the photovoltaic structure in an open configuration, and as the lead arm moves towards the base, the scissor link mechanisms retract the photovoltaic structure to place the photovoltaic structure in the closed configuration.

  • Publication number: 20220231636
    Abstract: A solar system, arranged in one or more sub-systems, consists of solar panels. The solar panels are configured into a plurality of solar panel strings, using interconnect wires, wherein a solar panel string comprises at least two of the solar panels electrically connected in a serial manner. The solar panels of a first of the solar panel strings are arranged between at least one of the solar panels of a second of the solar panel strings, and the interconnect wires, for each of the solar panel strings, form only a single path between the top and the bottom of the sub-system. This wiring configuration has application to house wires in a solar awning with limited space to house solar panel interconnect wires.

  • Publication number: 20210194416
    Abstract: Modular tracker systems that include at least first and second tables or are continuous without the use of tables, a single motor driving the first and second tables, first and second intra-table drive shafts and an inter-table drive shaft. Each table includes a support structure including first and second mounting posts, a frame supported by the support structure, at least one solar panel supported by the frame, and first and second gearboxes being concentrically aligned for each table. The first and second gearboxes are each configured to produce first and second outputs. The first output has a first rotational speed, and the second output has a second rotational speed less than the first rotational speed, and is operatively coupled to the frame. The inter-table drive shaft couples the second gearbox of the first table with the first gearbox of the second table, whereby the first and second tables are rotated synchronously.

  • Publication number: 20200266757
    Abstract: A preassembled solar panel module includes a solar panel configured for receiving and converting solar radiation to produce electrical power. Multiple panel rails are coupled in preassembly to a backside surface of the solar panel, including at least two panel rails disposed halfway or more along opposing longest edges of the solar panel. Multiple snap connector components are each coupled to one of the at least two rails and are each configured to couple with a complementary snap connector component of an adjacent preassembled solar panel module. One or more mounting feet are each coupled at a selected location to one of the at least two panel rails and are each configured for coupling at a selected location to a roof or other sunlight receiving surface.

  • Publication number: 20180041161
    Abstract: A mounting system and techniques for securing solar panels to a fixed structure including a plurality of mounting brackets and tracks and a plurality of mounting feet that connect to the tracks and anchor to the fixed structure. Each mounting bracket has a means to interconnect and interlock with the mounting brackets on adjacent solar modules. In addition, the mounting feet have a quick release mechanism to connect and disconnect from the track. The mounting feet are appropriately selected for the given fixed structure or roof type. The solar module system, in accordance with certain embodiments, has toggle anchors to reliably mount into sheathing plywood or OSB material. The solar module system, in accordance with certain embodiments, also describes an electrical conduction and coupling system for solar modules that integrates electrical coupling with mechanical coupling at the point of mechanical attachment.
