Abstract :
Energy Conversion Devices, Inc. (ECD) and United Solar Systems Corp. (United Solar) are developing lightweight, flexible photovoltaic modules that can replace conventional roofing materials and be economically and aesthetically integrated into residential and commercial buildings. The modules will be fabricated from high-efficiency multi-junction a-Si alloy solar cells developed by ECD and United Solar. These cells are produced on thin, flexible, stainless steel substrates. Two types of products, 1 ft by 10 ft overlapping PV shingles and 1.3 ft by 20 ft PV roof panels are being developed by United Solar and ECD, respectively. United Solar´s shingle type design uses a roof mounting procedures similar to those used with conventional asphalt shingles, while ECD´s PV panel uses mounting procedures conforming to metal roof systems. Thus, they can be installed on roof sheathings, replacing ordinary shingles or metal roofing panels, on a standard wood roof construction
