solar thermal collector calculations

Calculating solar thermal collector efficiency | Free Hot Water

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. The thermal efficiency of a collector is calculated by using the formula bellow: P= [ (Ti – Ta) / I] P= Inlet Fluid Parameter.
