EVALON® Solar cSi

EVALON® Solar cSi is the world’s first solar roofing membrane with semi-flexible crystalline silicon PV modules.

Product benefits

  • reliable protection of buildings against precipitation
  • direct conversion of solar energy into electric power
  • due to the extremely low weight (3.3 kg/m2) suitable even for roof constructions with a low bearing capacity 
  • two integrated solarmodules in one solar roofing membrane
  • quick and easy installation due to top-side connecting cables
  • the patented glass-fibre reinforced duromer core guarantees stability, flexibility and durability
  • glas-free, frameless, ultrathin, semi-flexible PV module with crystalline silicon solar cells
  • suitable for small roofs: requires a roof area of less than 10 m2/kWp due to the high effiency and installation with small module distances
  • dirt-repellent surface und very low glare effect (textured ETFE-frontsheet)
  • a minimum roof slope of 3° ensures the self cleaning effect of the PV-modules and the prevention of ponding water
