Prefabricated solar collector panels is a kind of new permeability structure of collector panels. For this test, we adopt a certain proportion of copper oxide, magnesium oxide and iron oxide to enamel paint as absorbed panel coating and make two kinds of collector panels for different forms of color by dark green coating and black coating. By the methods of comparison, the two kinds of panel collector efficiency and heat loss coefficient UL were tested. The results showed that there was a slight difference between the heat loss coefficient of prefabricated solar collector panels, using the panel with dark green coating’s comprehensive thermal effect is well than the panel with black coating. The beautiful appearance color is more suitable for building requirements.
