Organic Solar Film

HeliaSol - HeliaSol is a flexible, ultra-lightweight, ultra-thin organic ready-to-use solar solution for various applications.

HeliaSol® is an organic solar solution that helps customers to virtually convert any surface into a power-generating solar surface, helping the customers to become less susceptible to increasing energy prices.

HeliaSol® is flexible, ultra-lightweight and ultra-thin, which enables more surfaces to become energy generator. The film is perfectly suited on curved or non-straight rooftops, ones with low static conditions like old buildings or lightweight industrial buildings, which usually cannot take traditional PV solutions. Even Façade installations can be realised with HeliaSol®. The solar film is a ready-to-use product with a specific adhesive on the back, which is glued directly to surfaces like steel, concrete and rooftop membranes.
