  • 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.

  • Patent number: 10560050
    Abstract: Apparatus, systems and methods are provided for solar awnings or canopies that include rigid solar modules, for example photovoltaic cells or panels. The awnings have solar modules or panels stacked together substantially vertically (e.g., each module is oriented vertically with respect to the next module). The solar modules in the stack are interconnected to each other, such that each solar module is connected electrically and mechanically to adjacent solar modules. The first solar module in the stack of modules is fixed to one end of the base of the awning. The base of the awning is typically mounted to a building, vehicle, mobile home, or other appropriate structure. The last solar module in the stack is attached to a lead arm of the awning. The lead arm moves back and forth (e.g., away and toward) from the base of the awning to enable the expansion or retraction of the awning.
