The use of light reflected onto the rear side of the module makes higher yields of up to 25 percent possible, depending on the surface on which it is installed. Solarworld has developed a new racking system for flat roofs that is optimized for the bifacial technology. Sunfix Bisun mounts the module at a distance of 30 centimetres to the roof surface optimizing light capture for energy harvest. The increased elevation ensures optimized energy harvest without sacrificing the performance of the racking system.
The racking system consists of five pre-assembled components (three legs adjusted to a module tilt of 10 degrees, ballast tray, and, cable routing) and can be installed using only one tool. It is fixed to the roof through ballast. Roof bolts can be integrated into the system if required.
The legs are made of sturdy, weather-resistant material of stainless steel and aluminium. The Sunfix Bisun does not need any long rails: the longest part of the system is 80 centimetres long. This means it is easy to transport and needs little storage space. Sunfix Bisun can be attached to flat roofs with a roof-tilt of up to five degrees. It is suitable for various rooftop covers such as bitumen, gravel, foil or green roofs. The module and racking system are available immediately.
