Andreas ZieritzSome data from my solar thermal collector system in our house, situated in Bergen, Norway. Both collectors with a total of 18m2 have produced approximatly between 2100 - 2800 kWh per year.
That would be between half and 2/3 of the maximum calculated production.
The measurements are dependent on flow values which are estimated based on tank temperatures during production. Year to year differences are due to weather.
