Based on the recent development of renewable energy utilization technology, in addition to centralized photovoltaic power plants, distributed photovoltaic power generation systems represented by building-integrated photovoltaic systems are frequently employed for power supply. Therefore, in the architectural design, the double-glass photovoltaic module used in the integrated photovoltaic building system puts forward a higher load-bearing capacity requirement and the corresponding simplified method of carrying capacity check. This article focuses on the simplified method of checking the bearing capacity of the four-sided simply supported double-glass photovoltaic module. First, the principle of equivalent stiffness is used to calculate the effective thickness. Then, the rationality of this approach is verified by comparing the bending states of sandwich panels under different shear moduli. The double-glass photovoltaic module is equivalent to a single-layer board, and its effectiveness is verified by comparing the impact test results of the double-glass photovoltaic module with the results of the single-layer board. But the comparison with the test results shows that, from the perspective of architectural design, the effective thickness results in this paper can ensure that the building structure has sufficient bearing capacity, but the four-side simply supported boundary theory cannot fully reflect the calculation of the bearing capacity of the four-side clamped double-glass photovoltaic module.
