BTGA PV-System
Since July 2020, we have been operating our own solar power system on the HC building of the Haspel campus. Due to the flat inclined modules, the plant is practically not visible from the public space.
The system generates a maximum power of 24 kW. It contains from 76 modules, about half with a south-east and half with a south-west orientation, each with an inclination of 15°, so that the yield is distributed more evenly throughout the day. A frame construction made of aluminum profiles is used for the elevation, which is weighted down with concrete slabs to securely fix the system on the roof. The annual electricity yield in 2021 was 20 MWh. With 100% self-consumption coverage, the system thus contributed to reducing the building's grid electricity consumption by about 10%. In the context of the project, we also evaluated the energy consumption of all our university's properties.
The installation of the solar system and the energy analyses for our campus were funded by the European Regional Development Fund (EFRE) "Investments in Growth and Employment" in conjunction with state funds from the Ministry of Home Affairs, Local Government, Building and Equality of the State of North Rhine-Westphalia (MHKBG NRW) as part of the > Living Lab Building Performance < project.
In the first half of 2022, the yield was 10% higher than in the previous year due to sunny weather. This contributes to further reduction of the university's electricity consumption in the year of the energy crisis.
