20090320907 | PHOTOVOLTAIC MODULE AND MODULE ARRAYS - A photovoltaic (PV) module including a PV device and a frame. The PV device has a PV laminate defining a perimeter and a major plane. The frame is assembled to and encases the laminate perimeter, and includes leading, trailing, and side frame members, and an arm that forms a support face opposite the laminate. The support face is adapted for placement against a horizontal installation surface, to support and orient the laminate in a non-parallel or tilted arrangement. Upon final assembly, the laminate and the frame combine to define a unitary structure. The frame can orient the laminate at an angle in the range of 3°-7° from horizontal, and can be entirely formed of a polymeric material. Optionally, the arm incorporates integral feature(s) that facilitate interconnection with corresponding features of a second, identically formed PV module. | 12-31-2009 |
20100071744 | Photovoltaic Installation With Automatic Disconnect Device - A PV installation comprises a PV array, an electrical interface connecting a utility power source to an electrical load, and a DC to AC inverter. A first set of wiring electrically connects the PV array to the inverter through a disconnect device and a second set of wiring electrically connects the inverter to the electrical interface. A control mechanism connects the disconnect device to the electrical interface so that when power from the electrical interface is removed, the PV array is electrically disconnected from the inverter. The disconnect device may be a remote disconnect device located at a position at or near the PV array, such as in the space beneath a roof supporting the PV array. A method electrically disconnects a PV array from electrical wiring at a site. | 03-25-2010 |
20100252092 | PHOTOVOLTAIC ARRAY WITH MINIMALLY PENETRATING ROOFTOP SUPPORT SYSTEM - A photovoltaic array including a plurality of photovoltaic assemblies and a plurality of mounting units. The mounting units each include an elongate rail and a plurality of leg assemblies. The rail is sized and configured to maintain a portion of at least two of the photovoltaic assemblies, with the leg assemblies extending from the rail in a spaced-apart fashion and terminating in a foot for placement against a rooftop structure for minimally penetration installation. Further, at least one of the leg assemblies can include a retractable leg. When the photovoltaic array is installed to a rooftop structure including a membrane intermittently secured to a rooftop deck, the retractable leg accommodates upward billowing of the membrane under windy conditions. | 10-07-2010 |
20110113704 | WATER-RESISTANT APPARATUSES FOR PHOTOVOLTAIC MODULES - A water-resistant apparatus is provided. This water-resistant apparatus is positioned near a photovoltaic module. The water-resistant apparatus includes hollow, elongated conduits, and each conduit can hold water with surface tension based on exposure of the conduit to water. The surface tension causes a formation of a meniscus that inhibits a flow of water through the conduit. | 05-19-2011 |
20110114158 | REPLACEABLE PHOTOVOLTAIC ROOF PANEL - A replaceable building-integrated photovoltaic (BIPV) module system for mounting as roofing structures on a building is disclosed. The BIPV module system comprises a module and engagement means coupled to the building, the engagement means adapted to couple to the coupling means to releaseably couple the module to the building. The module comprises a photovoltaic laminate and a frame surrounding substantially entirely the perimeter of the photovoltaic laminate, the frame comprising coupling means. | 05-19-2011 |
20110232715 | MINIMALLY PENETRATING PHOTOVOLTAIC ASSEMBLY FOR USE WITH A SLOPED ROOF AND RELATED METHODS - An assembly which is lightweight includes an interconnected array of PV modules, where each PV modules is defined in part by a module outer perimeter portion. This array is defined in part by an outer perimeter portion including an upper edge portion, side edge portions, and a lower edge portion. The array is secured to a sloped roof along at least one of the upper or lower edge portion of the array. The assembly further includes interlocking features along the module outer perimeter portion which distribute uplift forces to adjacent PV modules. Additionally included is at least one wind deflector located along the lower edge of the array and non-penetrating base feet disposed on the sloped roof supporting at least a portion of the array. | 09-29-2011 |

20130019922 | FIRE RESISTANT PV SHINGLE ASSEMBLY - A fire resistant PV shingle assembly includes a PV assembly, including PV body, a fire shield and a connection member connecting the fire shield below the PV body, and a support and inter-engagement assembly. The support and inter-engagement assembly is mounted to the PV assembly and comprises a vertical support element, supporting the PV assembly above a support surface, an upper interlock element, positioned towards the upper PV edge, and a lower interlock element, positioned towards the lower PV edge. The upper interlock element of one PV shingle assembly is inter-engageable with the lower interlock element of an adjacent PV shingle assembly. In some embodiments the PV shingle assembly may comprise a ventilation path below the PV body. The PV body may be slidably mounted to the connection member to facilitate removal of the PV body. | 01-24-2013 |
20130255167 | ACTIVE FIRE-BLOCKING WIND DEFLECTOR - A rooftop photovoltaic solar system is disclosed. The solar system comprises a plurality of photovoltaic modules forming a rooftop array, the rooftop array having at least one edge and a wind deflector positioned along the edge of the rooftop array, the wind deflector constrained in a first configuration by a fuse. In the first configuration the wind deflector comprises a deflecting portion adapted to deflect wind blowing on the rooftop above the rooftop array and a ventilation portion having a plurality of openings, the openings positioned to permit airflow under the rooftop array. The wind deflector assumes a second configuration upon release of the fuse. In the second configuration, the deflecting portion is elevated from the first configuration and the ventilation portion is positioned to permit less airflow through the plurality of openings than in the first configuration. | 10-03-2013 |
