“Tübingen ears” generate electricity

The “Tübingen ears” are solar panels installed on open spaces that convert solar energy into electricity. Two of them are already located on the slip road of the B27 motorway near Lustnau. The third, the Traufwiesen solar park, is currently still under construction. By the summer, 15,000 photovoltaic modules will be installed along the B27 motorway in the direction of Stuttgart. They are expected to generate 8,800 megawatt hours of electricity per year—as much as 1955 families of four would consume in the same period. This is reported by the Tübingen municipal utility, which is building the plant in cooperation with the Tübingen-based company “BayWa r.e.”. It will be the largest solar park in the district of Tübingen. The first two “ears”, which will be completed in 2022, will supply a calculated 1157 megawatt hours of electricity per year. “Ears” is the colloquial name given to the slip roads of federal highways because of their shape.
Meanwhile, Tübingen’s municipal utilities have launched another project. The Au solar thermal park is to generate heat on 23,200 square metres. The plant, which is being built at the junction between the B 27 and B 28, is one of the largest solar thermal parks in southern Germany with a maximum heat output of 7 MW. The city wants to use it to drive forward the expansion of the district heating supply. In addition to the solar thermal plant, a large heat storage facility is also being built.
