First real test site in Norway

The first real test site for solar thermal energy capacity in Norway was built in 1977 in Lørenskog near Oslo by John Rekstad, professor of physics at the University of Oslo. The operation has been smooth since the installation leading to a total energy saving of approx. 280 000 kWh. The test has demonstrated the energy saving potential using solar energy even at high latitudes in the south of Norway (600N).

  • Built in 1977
  • Net gain from solar system: 7 500 kWh/a
  • Total maintenance costs: $ 150,-

This test building represented the kick-off of a solar energy project at the Department of Physics, University of Oslo. The project has addressed various aspects of new energy solutions like solar PV , aspects related to hydrogen as energy carrier, cooling of buildings, energy control and metering etc.
