Ruukki has Developed a Fully-Integrated Solar Panel Facade

Ruukki is the first company to have developed a photovoltaic system that has been fully integrated into a facade to convert sun rays into energy. The solar power system does not depend on the sun's warmth, only its radiation. The electricity generated is used either to meet the building's own needs or is fed into the electricity grid.
