Abstract: A photovoltaic module incorporates a lamination including a back-sheet, an array of solar cells supported on the back-sheet, and a transparent protective covering over the array of solar cells. The solar cells are arranged in offset or staggered patterns on the back-sheet to present a more random and less rigid industrial appearance to an observer. In some cases, cleaved solar cell segments are arranged into groups that are staggered on the back-sheet. This allows for finer control of the net voltage produced by a module. In other embodiments, full single wafer solar cells are arranged into larger groups, which themselves are staggered on the back-sheet. In either case, the result is a photovoltaic module with an appearance that is more organic and acceptable to homeowners and architects than traditional modules having cells arranged in rigid aligned rows and columns.

Abstract: A roofing system including a cap shingle and methods of producing a cap shingle and forming a roof are disclosed. In one embodiment, the cap shingle can include at least one layer of shingle material including an upper surface having a headlap portion and an exposure portion, and a lower surface. A sealant can be applied along the lower surface and a sealant attachment zone can be positioned along the upper surface of the at least one layer of shingle material between the headlap and exposure portions. The sealant attachment zone can be configured to contact a sealant applied along a lower surface of a next cap shingle to promote adhesion between the cap shingles installed along a ridge, hip, or cap of the roof.

Abstract: A hail resistant roofing system and method includes a roofing substrate such as a shingle or tile or membrane having an array of exposed upwardly projecting features.

Abstract: Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.
