Photovolatic membrane

As Fatra has a wealth of expertise in manufacturing waterproofing base membranes, it is the Fatrasol photovoltaic function that especially deserves a few words.

Photovoltaic cells are integrated on the top surface of waterproofing bands and they must be identically flexible. Uni-Solar, the photovoltaic cell supplier, currently manufactures flexible triple-junction photovoltaic cells based on amorphous silicon.

Their core component is a high-grade steel foil onto which three silicon layers are affixed atop each other with additional trace elements so that the layers use different bandwidths of the solar radiation spectrum.

Advantages of solar membrane roof over solar panels

The photovoltaic and waterproofing functions of the roof are combined in a single membrane:

• The unique triple-junction technology by Uni-Solar generates the maximum amount of electricity possible under current weather conditions (up to 15 to 20% more than conventional single-junction solar panels).
• Easy to install and replace, light weight, long durability, flexibility, may be walked on
• No bonding primer, formwork, frames or reinforcement required
• 25-year warranty for roof function (at least 80% performance of output power during the warranty period)
• A comprehensive roofing solution with professional support
• The Fatrasol membrane may be combined with thermal insulation, producing a comprehensive roofing system with waterproofing, photovoltaic and thermal insulation functions
