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 photovoltaic mounting system for tile roofs is disclosed. In one embodiment, mounting bracket is attached to a roof deck and passes through a flashing support and flexible flashing that mimics the contour of the adjacent roof tiles. In other embodiments, a tile hook passes through partial or full tile replacement flashing. A plug or other structure blocks the space around the tile hook preventing the ingress of pests and debris under the flashing and surrounding tiles. Additional photovoltaic module mounting hardware, including sections of rails and frame mounts are attached either the mounting bracket or tile hook.

Abstract: A system for mounting a photovoltaic array onto short sections of mounting rails such that a section of mounting rail is only installed fewer than all the photovoltaic modules in the array. A single section of mounting rail may support one, two or three photovoltaic modules depending on it's length and position respect to the edge of each module frame.

Abstract: The invention includes an apparatus for mounting a photovoltaic (PV) module onto a structure where the apparatus includes a base portion, a stud portion, and a coupling portion. The coupling portion includes a male portion that acts as a spring under load and a clip portion that penetrates the PV module frame to create a grounding bond. The apparatus includes a lower jaw, shaped to pry open a groove, and a key portion that can compress to allow for tolerances. The invention further includes a clip with one or more tabs and one or more teeth. The invention further includes a replacement roof tile which includes a support structure with a horizontal flange, a vertical component, a horizontal component, a flashing with an upper surface and a lower surface, and a tile-shaped metal surface having a curvilinear shape that reflects the shapes of adjacent tiles.

Abstract: A tile hook and flashing assembly, having: (a) a lower flashing; (b) an upper flashing; (c) a tile hook; and (d) a seal, wherein tile hook extends through an aperture passing between overlapping portions of the upper and lower flashings, and wherein the seal extends across the aperture and seals around the tile hook.

Abstract: A method of locating a drilling apparatus and/or a borehole in a subterranean region. The method may include the steps of transmitting seismic waves into the subterranean region during a subterranean drilling operation, the seismic waves being transmitted from a location remote from the drilling apparatus, detecting a seismic response from the drilling apparatus or borehole, and comparing the detected response with predetermined seismic survey data of the subterranean region to determine the location of the apparatus or borehole.

Abstract: A skirt for photovoltaic arrays provides a screen portion, a groove portion, and a separate coupling adapted to couple the skirt to the skirt of an adjacent photovoltaic array and to a photovoltaic module. Another embodiment provides a screen portion comprising an angled louver and is adapted to partially obscure an area substantially beneath a PV module in a PV array. A further embodiment provides an edge blocking skirt for a PV array comprising a screen portion adapted for mounting a bottom of the screen portion substantially close to a roof.

Abstract: A photovoltaic array, including: (a) supports laid out on a surface in rows and columns; (b) photovoltaic modules positioned on top of the supports; and (c) fasteners connecting the photovoltaic modules to the supports, wherein the supports have an upper pedestal surface and a lower pedestal surface such that the photovoltaic modules are positioned at a non-horizontal angle when edges of the photovoltaic modules are positioned on top of the upper and lower pedestal surfaces, and wherein a portion of the fasteners rotate to lock the photovoltaic modules onto the supports.
