Flexible Solar Roof Covering
A system is now available in the UK which allows us to fully integrate photovoltaic’s into a flat roof membrane covering.
• No issues with glass
• No issues with weight
• No issues with aesthetics
The TF Membrane Professional, which incorporates unique Thin-Film Amorphous Silicon laminates from Uni-Solar®, has been designed for the flat roof sector; a roofing membrane with built-in power generation (BIPV)(solar roofing membrane). The flexibility of the solar membrane offers the freedom of design to architects, as it can conform to curved surfaces.
It also allows the increased demand for aesthetically pleasing building-integrated photovoltaic modules (BIPV). By using a building integrated PV system, there is no need for large and heavy framework, and can be used for retrofitting in existing buildings where weight and wind loads are critical to the roof sub-structure. The Biosol Membrane System is installed with traditional methods, weighing just 5kg/m2 compared to50kg/m2 for some fixing frames.
The glass-free durable polymer laminates have proven themselves under the most extreme weather conditions imaginable, including satellites, ocean buoys and military applications, and are resistant to vandalism.
Thin-Film laminates render better energy yield at high module temperatures and in warm climates. Under real outdoor conditions, module temperature can be up to 80°C, especially if they are building-integrated and directly in the sun. At these temperatures, thin-film laminates can yield up to 20% more electricity compared to conventional crystalline solar modules of the same power rating. As well as high temperature performance, Triple Junction laminates offer high outdoor performance in low and diffused light conditions due to higher absorption of light in the blue wavelength range. If a solar cell is broken or comes under shading, the electricity can by-pass the cell to continue the flow of electricity by using specially designed solar by-pass diodes. This enables the module to continue to operate with dysfunctional cells.
