  • Publication number: 20030222479
    Abstract: A PV roof assembly (6) includes a roof (12) mountable to an electric vehicle (4), and a PV assembly (10) at the upper part of the roof. The PV assembly may be mounted to a separate roof surface (34) or the PV assembly may itself constitute all or part of the roof. The vehicle may include a secondary PV assembly (96) coupled to a display unit (92) to provide an independent indication of the intensity of solar irradiation. The roof may have mounting element recesses (68) to accommodate mounting elements (70) of the PV assembly, the mounting elements configured so as not to shade the PV panel (14). The roof may also be configured to accommodate a global positioning device (80). The roof preferably includes a peripheral gutter (88). The roof body preferably includes hand-hold recesses (90) housing hand-hold elements (42) at positions to provide a horizontal setback (92) from the lateral sides (93) of the roof body.

  • Publication number: 20030164187
    Abstract: Each PV assembly of an array of PV assemblies comprises a base, a PV module and a support assembly securing the PV module to a position overlying the upper surface of the base. Vents are formed through the base. A pressure equalization path extends from the outer surface of the PV module, past the PV module, to and through at least one of the vents, and to the lower surface of the base to help reduce wind uplift forces on the PV assembly. The PV assemblies may be interengaged, such as by interengaging the bases of adjacent PV assemblies. The base may include a main portion and a cover and the bases of adjacent PV assemblies may be interengaged by securing the covers of adjacent bases together.

  • Publication number: 20030154680
    Abstract: A barrier, such as a PV module, is secured to a base by a support to create a shingle assembly with a venting region defined between the barrier and base for temperature regulation. The first edge of one base may be interengageable with the second edge of an adjacent base to be capable of resisting first and second disengaging forces oriented perpendicular to the edges and along planes oriented parallel to and perpendicular to the base. A deflector may be used to help reduce wind uplift forces.

  • Publication number: 20030154667
    Abstract: A barrier, such as a PV module, is secured to a base by a support to create a shingle assembly with a venting region defined between the barrier and base for temperature regulation. Water resistant junctions may be formed between the bases of adjacent shingle assemblies of an array of shingle assemblies. The base may include an insulation layer underlying a water barrier. The base may also include a waterproofing element; the width and height of the barrier may be shorter than the width and height of the waterproofing element.

  • Publication number: 20030154666
    Abstract: A barrier, such as a PV module, is secured to a base by a support to create a shingle assembly with a venting region defined between the barrier and base for temperature regulation. The bottom edges of the barriers of one row may overlap the top edges of the barriers of another row. The shingle assemblies may be mounted by first mounting the bases to an inclined surface; the barriers may be then secured to the bases using the supports to create rows of shingle assemblies defining venting regions between the barriers and the bases for temperature regulation.

  • Patent number: 6534703
    Abstract: The invention is directed to a PV assembly, for use on a support surface, comprising a base, a PV module, a multi-position module support assembly, securing the module to the base at shipping and inclined-use angles, a deflector, a multi-position deflector support securing the deflector to the base at deflector shipping and deflector inclined-use angles, the module and deflector having opposed edges defining a gap therebetween. The invention permits transport of the PV assemblies in a relatively compact form, thus lowering shipping costs, while facilitating installation of the PV assemblies with the PV module at the proper inclination.

  • Publication number: 20030010374
    Abstract: The invention is directed to an array of photovoltaic (PV) assemblies mountable to a support surface. Each PV assembly comprises a base, a PV module and a support assembly securing the PV module to a position overlying the upper surface of the base. The base comprises a main member and a cover defining the upper surface of the base; the cover comprises an electrical conductor. An electrical ground connector may be made between the covers of different PV assemblies. The cover may comprise sheet metal and may have an electrically-insulating surface layer. The main member may be a thermal insulator and the cover may comprise a low-emissivity layer. The covers of adjacent PV assemblies may be interengaged so that wind uplift forces on one of the PV assemblies tend to transfer to adjacent the assemblies so to help counteract the wind uplift forces.

  • Patent number: 6495750
    Abstract: A stabilized PV system comprises an array of photovoltaic (PV) assemblies mounted to a support surface. Each PV assembly comprises a PV module and a support assembly securing the PV module to a position overlying the support surface. The array of modules is circumscribed by a continuous, belt-like perimeter assembly. Cross strapping, extending above, below or through the array, or some combination of above, below and through the array, secures a first position along the perimeter assembly to at least a second position along the perimeter assembly thereby stabilizing the array against wind uplift forces. The first and second positions may be on opposite sides on the array.

  • Patent number: 6313394
    Abstract: A PV roof assembly (6) includes a roof (12) mountable to an electric car (4), and a PV assembly (10) at the upper part of the roof. The PV assembly may be mounted to a separate roof surface (34) or the PV assembly may itself constitute all or part of the roof. The PV assembly may include a monolithic PV panel (14) with a plurality of PV cells (20). The roof may define a storage region (32) accessible through a closable access opening (44). The roof may include a circumferential lip (24) which extends around and above the PV assembly to help prevent damage to the PV panel. The roof may include a protective, at least semi-transparent top layer (60), an at least semi-transparent bottom layer (62) and a semi-transparent PV layer (64) secured between and in contact with the top and bottom layers to create a roof which is itself semi-transparent. The ratio of PV cells to the number of battery cells may be chosen to create a self-regulating design.
