| Abstract: | Thermal properties of flat-plate solar collector are always judged by its efficiency equations and curves. As for this problem, there have been quite detailed derivation and conclusions. Scholars used three different equations and curves to describe the quantity of efficiency, however, there is rare unified analysis among the three. Therefore, many readers are apt to be confused with some relative concepts. As a result, this paper analyses the similarity and difference of the curves, and presents a practicable solution as well. |
