+ Ready to be bonded on many qualified membranes and metal surfaces
+ Adhesive over the full back area of the flexible solar laminate – ensures lifetime adhesion
+ Reduced BOS cost due to simple peel & stick adhesive – No additional mounting hardware or assembly times required
+ Non penetrating roof installations – no risk of water leakage or roof damage
+ Lightweight solar installation allows installation on every roof, no roof enforcement or extra ballast required
+ Safe installation with lightweight panels- no heavy bulky glass panels on the roof, which might be a risk for safety
+ Flexible solar panels are bonded flat on roof and do not add additional wind load to the roof, much better aerodynamic design for high wind speed areas
+ Uniform black design provides the best look, important for architects and buildings with visible roofs
+ Durable non-breakable Swiss made solar panel design
+ Highest shade tolerance due to laser interconnected thin film cells
+ High energy yield in all light conditions due to CIGS technology
