Consider a collector with an absorber plate and cover. The absorber temperature is fixed at 50 °C. Assume that its absorptivity to solar radiation is 0.9 at normal incidence and the transmissivity of the cover is 0.9 at normal incidence. From 13:00 to 14:00, the beam irradiation, 16 = 1.5 MJ m 2 and diffuse irradiation, Id = 0.6 MJ m².
