Our PhD student Eivind Sveen has found that degradation rates in the Nordic conditions are considerably lower that in other climates.

Eivind Sveen has investigated the degradation rates of the PV system located at ASKO Vestby, and found that the yearly degradation rates are only 0.1 – 0.2 %, which is considerably lower than what the 25 year warrant promises (0.8 % yearly degradation).

Eivind Sveen, Josefine Helene Selj and Gaute Otnes has written about this in Dagens Næringsliv, and the article can be found here.
