The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.

Photovoltaic roofing elements and photovoltaic roofing systems

A method of forming an asphalt mixture can include mixing a bio-source material and a bitumen source to form a bitumen mixture. The bitumen mixture can be mixed with a catalyst to form the asphalt mixture. Particles can be added to the asphalt mixture to form a roofing-grade asphalt mixture. In an embodiment, the bitumen source material can have a softening point of at least approximately 93&#xb0; C. and a penetration distance no greater than approximately 25 dmm. In another embodiment, the roofing-grade asphalt mixture can have a softening point of at least approximately 104&#xb0; C., a penetration distance no greater than approximately 12 dmm, a viscosity of at least approximately 3000 cps at a temperature of 204&#xb0; C., or any combination thereof. The asphalt mixture can be applied to a base material to form a roofing product. The asphalt mixture can be applied as a pavement product.

A process for preparing roofing granules includes forming kaolin clay into green granules and sintering the green granules at a temperature of at least 900 degrees Celsius to cure the green granules until the crystalline content of the sintered granules is at least ten percent as determined by x-ray diffraction.

Solar-reflective roofing granules having deep-tone colors are formed by coating base mineral particles with a coating composition including an infrared-reflective pigment. Color is provided by a colored infrared pigment, a light-interference platelet pigment, or a metal oxide.

The retention of roofing granules on bituminous roofing products is enhanced by providing an adherent material in the interstices between the exterior surface of the roofing granules and the exposed upper surface of the base sheet.

Method of producing roofing shingles with enhanced granule adhesion

A building panel of the roofing or siding type is disclosed, as well as a building structure having such roofing or siding panels, in which the panels are comprised of two different types of building materials. The composite panel includes at least one layer of synthetic polymeric building material, having adhesively secured thereto at least one layer of asphalt based building material, with outer, upper surfaces of the panel, that would be weather-exposed in the installed condition on a building structure being comprised of the asphalt based building material, and with the synthetic polymeric layer(s) of polymeric building material being weather-protected in the installed condition on a building structure.

Panel for use as exterior covering for roofing or siding and building structure having same

Algae-resistant roofing granules are formed by extruding a mixture of mineral particles and a binder to form porous granule bodies, and algaecide is distributed in the pores. Release of the algaecide is controlled by the structure of the granules.
