The office building and industrial monument Weiherallee 11 is located on the Zellweger site in Uster. The building’s flat roof was renovated and equipped with an 88 kWp photovoltaic system in 2021. Towards this end, we created a comprehensive photovoltaic concept that was independent of any given manufacturer. We then completed the technical planning, drafted the invitation to tender, and oversaw the system’s installation.
