Solar cells on TU Delft roofs

TU Delft is working to make the campus more sustainable. The objective is to sustainably generate a quarter of the energy requirement ourselves in 2020 or to purchase this, to save 40% on energy and to have halved CO2 emissions.

One of the sustainability projects consists of installing solar panels on the campus’ roofs. An SDE+ subsidy has been received from the government to this end (Stimuleringsregeling Duurzame Energie). Some of the solar panels are used as a testbed for research and education.

The solar panel capacity installed amounts to 1.2 MWp which provides 1,000,000 kWh of electricity annually, allowing part of the university to be supplied with electricity.

Check the real time and lifetime yields of the 4,000 solar panels.
