Performance of evacuated flat plate solar thermal collectors

An evacuated flat panel with a highly selective coating can achieve a significantly higher efficiency than is available from the best conventional flat panels, evacuated tubes or trough collectors. The benefit is most marked at T M / G > 0.15 which in a typical water heating application might equate to G < 500 W/m 2.

Concentrating vs Flat Plate Collectors for Solar Heating

The main factor (I think) that tends to favor the concentrating collector in this test is that the heat loss from the absorber should be smaller because the absorber area is much smaller, and the evac tube insulation used should do a good job of insulating. On the other hand, the flat plate collector absorber receives more light because of the ...
