The photovoltaic (PV) modules were integrated with the assembled concrete using a reverse molding process and the performance of the prepared prefabricated concrete PV facades were studied. The results showed that PV backsheet can meet the requirements of alkali resistance and tensile performance tests, proving that the PV panel can be fixedly bonded to the concrete and not corroded; when the PV module works, the temperature of its own was mainly influenced by the weather, while it was adversely affected by the heat storage in the concrete, the maximum temperature of the prefabricated concrete PV facades throughout one year was 60.4 °C, which was in line with the standard, and it was obtained through PVsyst that the efficiency of PV module's photovoltaic conversion decreased by 8%, whhich basically did not affect its normal use. Meanwhile, when the prefabricated concrete PV facades applied to the facade and generated electricity, the power output per unit area of PV modules was lowest in Summer and highest in Winter, with an increase of approximately 37% due to solar altitude angle and effective irradiance.
