Revolutionary, cost efficient bitumen rooftop membrane with integrated photovoltaic modules
The worldwide photovoltaic (PV) industry has been in an atmosphere of continued growth for many years. Yearly growth rates of 40% on average have kept the PV industry extremely competitive. Compared to other renewable energy sectors Austria has so far not benefited significantly from the high global PV-growth, despite the availability of a broad market for penetration.
Building-integrated photovoltaics (BIPV) are the solution of the future as they combine many practical advantages. One major advantage is that the façade of a building, its windows or roof tops can, aside from their usual purpose, act as power generators due to the multi-functionality of BIPV-modules. Therefore the generation of power will become an integral part of the building. At the moment production of BIPV-modules is still dominated by high production costs and the modules currently produced rarely conform to the market needs in terms of aesthetics and flexibility which are required for successful building integration. In cooperation with Soprema, crystalsol’s PV-modules and the cooperatively designed production process shall be adapted in order to integrate the flexible photoactive layer cost-effectively into waterproof roof membranes. The combination of crystalsol’s cost effective and flexible PV-technology with Soprema’s waterproof membranes allows producing electricity in addition to protecting the roof against weather conditions. At the end of the project the first roof membranes with integrated PV-layers will be produced; the membranes will be a major achievement due to the significantly lower production costs and adaptability. This guarantees a successful penetration of the building integrated photovoltaics market.
