What is the efficiency of solar collector?
What is the efficiency of solar collector? The collector efficiency is obtained here, without reflector as 51%, and with reflector as 61%. Thus, the overall efficiency of the flat plate solar collector is increased approximately 10% by using the reflector with the collector. How is solar thermal collector efficiency calculated? One method is to compute the thermal efficiency of a collector, which is the ratio of the average heat output from the collector divided by the rate that solar radiation strikes the panel. I = solar radiation intensity striking the collector (Btu/hr/ft2). What is the current efficiency of solar thermal...
