 System Performance
50,000 kWh annually Challenges Installation of single ply thin film BIPV on built-up roof Solutions Re-roof with TPO/PV modules. New roofing materials and PV modules applied successfully and the costs of roof/modules are now depreciated as a business expense. Environmental Eliminates 1,000 tons of carbon dioxide impact over the life of the roof. How This system consists of silicon solar cells built into a single ply membrane roofing “sheet.” Sheets of 60 mil PVC roofing membrane are rolled onto the roofing surface and sealed with hot air welding create a waterproof surface; Next, solar cell modules measuring 4’ by 8’ are heat-weld bonded to the surface, creating a unified roofing system with built-in solar cells. The roof and solar power system become one without penetrating the roofing structure. Partners - Atlas-Pellizzari Electrical Corporation
