In collaboration with Carl Stahl Architektur, manufacturer of stainless steel cable and mesh constructions, and material supplier Merck KGaA, Belectric OPV (organic photovoltaic), with offices in North and South America, has developed a unique energy-generating shade sail in the shape of the African continent.
The combination of flexible organic solar modules and a stainless steel cable construction has allowed the realization of a solar project of this magnitude for the very first time. The complex system, measuring approx. 25 x 20 metres overall, consists of 445 individual transparent blue modules, using Merck’s “lisicon” OPV active material, and held in place by a sophisticated stainless steel cable mesh construction directly underneath the membrane dome above the Peace and Security Building’s interior.
The translucency of the modules makes for approx. 75% light transmission for the overall roof surface. Furthermore, thanks to the OPV modules, the shade sail supplies sufficient electricity to power the LED lighting system inside the building.
