Abstract: A vent is disclosed for use in ventilating attic spaces beneath a hip roof. The vent is configured to be installed along a hip of the roof overlying and covering a ventilation slot. The vent includes an elongated laterally flexible top panel from which baffle arrays depend. The baffle arrays include a plurality of curved vanes that arc away from the slot. The vanes are configured to redirect wind-blown rain and snow away from the slot and block the migration of rain and snow through the vent. Filler strips can be attached beneath the edge portions of the vent. The filler strips conform to underlying shingles when the vent is installed to fill gaps that might be formed between the vent and the shingles. A weather filter can be positioned over some of the baffle arrays to allow attic air to pass but prevent ingress of blown snowflakes and raindrops.

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.
