Energy Loss Rate

Among the energy loss, the radiation heat loss has the maximum rate as 1019.801 W, while the convection heat loss rate is 260.334 W. Because, solar energy systems mostly depend on radiation heat transfer phenomena. So, it is normal that radiation heat transfer has higher than the convection. Fig. 2.
