EVALON® Solar cSi is the world’s one and only solar roofing membrane with semi-flexible crystalline silicon PV modules.
alwitra. Innovations for long-term reliable flat roofs.
For 55 years, we have been passionate about flat roofs.
Drawing also on 20 years of know-how in solar technology, we provide our clients with unique integrated solutions from a single source, ranging from high-quality roof waterproofing using our proven flat roof systems to complete solar roofscapes.
Take advantage of the expertise of alwitra as the inventor of solar waterproofing membranes with a global record of more than 2,000 successfully completed solar projects.
EVALON® Solar cSi - The power-generating waterproofing membrane.
- low net weight of only 3.3 kg/m2, also suitable for roofs with a low bearing capacity
- two integrated solar modules in one solar waterproofing membrane
- easy laying and installation thanks to topside connecting cables
- direct conversion of solar energy into electric power
- ultra light-weight, semi-flexible PV module with crystalline silicon cells, without glass or framework
- small required roof area (less than 10 m²/kWp) thanks to high efficiency
- dirt repellent surface und very low dazzling effect (textured ETFE front sheet)
