Photovoltaic system of the Faculty of Electrical Engineering, Computer Science and Media Technology

Bergische Universität Wuppertal is also making a contribution to the energy transition. At the Freudenberg Campus, home to the Faculty of Electrical Engineering, Information Technology and Media Technology, a large photovoltaic system was installed in 2014. Many lectures at this campus train students in the field of renewable energies and related technologies. Lectures on wind turbines, photovoltaics, power grids, and power electronics and control engineering are thus part of the daily routine, but lecturing also means living by example, which is why the faculty decided to generate some of the energy needed by this high-tech campus itself. The system was erected on the parking lot of the Freudenberg campus and elevated with an aluminum support structure to a height that does not significantly impair further use of the parking areas, but rather provides pleasant sun protection for the cars parked below. A total of 444 individual photovoltaic modules extend in six rows over the 125m long system, which has an output of over 115 kWp. The energy is fed into the university's own distribution network via a total of eight inverters. Of course, having its own photovoltaic system also offers completely new possibilities on a campus like this. The system, which has just been completed, is already being used directly for scientific purposes and has been equipped with eight charging points for electric vehicles. Here, students, staff and guests can charge their electric vehicles free of charge during lectures, working hours or when visiting the nearby cafeteria. In the background, the latest control technology for low-voltage networks is being tested and optimized, which controls the power flow from the charging processes, the feed-in of the photovoltaic system and the cooling of the AliceNext supercomputer.
