Abstract: Flexible interconnects for attaching overlapping strings that can be part of a photovoltaic module. The interconnects can absorb strain caused by non-uniform heating and other loads encountered by the photovoltaic module.

Abstract: Photovoltaic modules are constructed having separate positive and negative junction boxes positioned at the corners of each photovoltaic module. A photovoltaic array assembled from these photovoltaic modules can be aligned such that the positive and negative junction boxes connect in an arrangement that minimizes the amount of wire needed to install the photovoltaic array. The arrangement of photovoltaic modules connecting the positive and negative junction boxes on adjacent photovoltaic modules leads to successive rows of photovoltaic modules in the photovoltaic array are oriented in opposing directions.

Abstract: Systems and methods for assembling and wiring photovoltaic arrays are provided. The wiring systems can include retractable wires included in photovoltaic modules that may be extended during installation of photovoltaic modules in the array to connect to wires of adjacent photovoltaic modules, which can retract into a tightened position under the array as the installation is completed. The wires may be made retractable by wire retraction mechanisms mounted to a frame of the photovoltaic module, which maintain a desired tension on the wires of the photovoltaic module. The wire retraction mechanism may include springs that urge components connected to the wire to rotate a particular direction so as to maintain tension on the wire. The wiring systems may also have wire guides to keep the wires accessible for installation and adjustment.

Abstract: An attachment point apparatus and system for photovoltaic arrays is disclosed. One embodiment provides a rail system for receiving a PV module, including a first rail, a second rail, a substantially rectilinear double male connector adapted for coupling an end of the first rail to an end of the second rail, and a connector adapted to attach a PV module to the first rail. Another embodiment provides a PV module including a PV laminate, a frame integral with and supporting the PV laminate, and a spanner bar adapted to solely span a width of the PV module, orthogonally connect at various locations along the frame, and attach to a support structure. A further embodiment provides a coupling device for a PV module comprising a first coupling portion adapted to rotatably engage a PV module, and a second coupling portion adapted to rotatably engage a rail.

Abstract: A system for connecting a photovoltaic mounting rail onto a mounting post using a connection system with a pair of interlocking grasps having interdigitated fingers that can be locked into the mounting rail when moved by a fastening system.

Abstract: Roof-mounted venting devices adapted for use with roof mounted photovoltaic (PV) panels are provided. Venting devices and assemblies can include a replacement flashing that fits over a cut-down roof pipe vent as well as venting assemblies that redirect airflow from a roof pipe vent. Such replacement flashing can include a substantially planar flashing portion having a raised portion for accommodating any residual flashing or roofing debris. Such replacement flashing may further include a hood portion with one or more vent openings to allow airflow into and out from the interior of the hood portion. Venting assemblies can include a coupling portion for mating with a vent-pipe, a section of hose or piping to redirect airflow, and a venting portion disposed outside or between roof-mounted solar panels.

Such replacement flashing can include a substantially planar flashing portion from which protrudes a hood portion with one or more vent openings to allow airflow into and out from the interior of the hood portion. The vent openings can be configured as a series of louvered openings that open in a down-roof direction to prevent flow of run-off and debris into the hood portion. Venting assemblies can include a coupling portion for mating with a vent-pipe, a section of hose or piping to redirect airflow, and a venting portion disposed outside or between roof-mounted solar panels.

Abstract: A photovoltaic array mounting system for a low-slope roof having interchangeable first and second bases, with a short leg extending from the first base at a non-vertical angle and a long leg extending from the second base at a non-vertical angle, wherein the short and long legs support opposite sides of a photovoltaic module such that the module is held at a non-horizontal angle, and wherein rock-in connectors are provided on top of the short and long legs permitting fast and easy system installation.

Abstract: An interlocking system for connecting photovoltaic module frames to a torque tube, including: (a) an interlock dimensioned to be positioned between the sides of two adjacent photovoltaic module frames; (b) a pair of couplings or flanges, wherein the couplings or flanges connect the interlock to both of the adjacent photovoltaic module frames; and (c) a U-lock connected to the interlock, wherein the U-lock is dimensioned to be connected to a torque tube.

Abstract: An apparatus and system for quickly and easily assembling PV modules into a PV array in a sturdy and durable manner. In some embodiments, the PV modules may have a grooved frame where the groove is angled into the frame with respect to the planar surface of the modules. Various components may engage within the angled groove to assemble the PV modules into the PV array using what may be referred to as a pivot-fit connection between the components and angled groove. Other embodiments may operate with PV modules having frames without angled grooves as by use of wraparound brackets.

Abstract: A solar array with successive rows of photovoltaic modules angled in opposing directions forming peaks and valleys between the rows with the valleys (i.e.: lower sides of the photovoltaic module rows) being mounted close together and the peaks (i.e.: upper sides of the photovoltaic module rows) being mounted far apart to improve system aerodynamics and permit ease of access for installers. Included is a system for connecting the upper sides of the photovoltaic modules to connectors that slide on bars extending between upper and lower mounting bases and for pivot locking the lower sides of the photovoltaic modules to the lower mounting bases.
