Rooftop PV and BIPV A Huge Energy and Design Potential Intersolar - PowerPoint PPT Presentation

Rooftop PV and BIPV – A Huge Energy and Design Potential Intersolar Middle East Conference Dubai, Sept. 26, 2017 Dr. Erich W. Merkle, CEO Almaden Europe

Rooftop PV and BIPV – A Huge Energy and Design Potential BIPV = Building Integrated Photovoltaic BAPV = Building Applied Photovoltaic • BIPV refers to PV and modules which are integrated into the building envelope as part of the building structure • it can replace conventional building materials • BIPV modules can be naturally blended into the design of the building. • Can be used in any external building surface, no land requirement • Dual advantage e.g. shading, weather protection • Energy can be consumed on ‐ site, no transmission loss • Modern, ecological statement through the building 2

7. Bifacial Modules + 10-20% extra yield: low reflecting surfaces (e.g., tile roof, grass); Mounting distance to substrate max. 40cm + 20-30% Extra yield: good reflective surfaces (eg flat roof with gray film, sand); Mounting distance to the ground 40cm -1.5m + 30-35% excess: very good reflective surfaces (e.g. glacier, snow); Mounting distance to the ground larger than 1.5m 28

Outlook and Market Potential : No. of Poten installation Drivers tial s p.a. 10 mill. zero energy building ordinance, 1. Rooftop and PV Roofs +++++ private consumption 0,8 mill. zero energy building ordinance, 2. Carports +++ private consumption, e ‐ car charging 0,5 mill. zero ‐ energy house, private 3. Terraces and Patio ++ consumption 0,01 mill. Green Building, zero energy building 4. Facades ++ ordinance, aesthetics 0,5 mill. dual benefit, climate protection is 5. Shading ++ becoming an important issue aesthetics, Green Building 6. Architectural design + 0,003 mill. 0,1 mill. High efficiency and up to 35% extra 7. Bifacial modules +++ yield, aesthetik 29
