Rooftop PV and BIPV – A Huge Energy and Design Potential

  • 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

BIPV = Building Integrated Photovoltaic

BAPV = Building Applied Photovoltaic

+ 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
