Arthur Buechel has been engaged in photovoltaics for more than 20 years. He has worked intensively on the topic of dual-use photovoltaics in close collaboration with Prof. Dr. Franz Baumgartner. This has resulted in solar systems on steel cables, the first PV folding roof system worldwide and now the URBANROOF and URBANBOX solutions, which offer new possibilities for developing the huge potential in of urban areas with dual-use PV.
