The solar folding roof HORIZON uses industrial areas for solar power generation twice.

dhp technology has developed the solar folding roof and produces it highly automated at the Zizers site. Together with partner dhp installs the solar folding roof and takes over the service and maintenance. The double use of an industrial area for solar power production without any restriction of this area is unique worldwide and possible thanks to its unique lightweight construction and patented folding mechanism. The solar folding roof establishes infrastructure-integrated photovoltaics.
