Hi you all,
I know this is a very simple question, but I amm stuck on it , pleqase help.
I try to calculate the efficiency of a collector field simply by dividing useful gain by the total irradiance on the collector's plane, but obviously this should be made only when the denominator i snot zero. I tried some logical operations in an equation but cannot get it.
Any help will be more tha welcome
