Attached is a picture of our 48 square foot installation in NW Minnesota.
Now snow on the ground and have had days down to -20 degrees Fahrenheit and the collector got up to 120 degrees. In the short days here it only runs for a few hours but does help heat the indoor pool, which we then draw the heat from with a heat pump to heat the house. Next year we should get an earlier start so should contribute a great deal more. [I] am using a single pane polycarbonate glazing.
