The operating temperature significantly affects the efficiency and degradation of the photovoltaic modules. Higher temperatures contribute to various degradation mechanisms, thermal cycling also have an impact on degradation rates. For the estimation of temperatures for the monofacial photovoltaic modules various models have been proposed, however, there are still not many studies on temperature estimation for the bifacial modules, which are going through a period of expansion in the market. In the present study, some steady-state models initially elaborated for the monofacial modules have been applied to the bifacial ones, evaluating the consistency of the estimation results with the measured temperature values. Some adjustments to monofacial temperature models are also proposed to take into account the irradiance on the back of the module. Finally, multi-variable polynomial models for the estimation of the bifacial module temperatures are proposed and tested.
