研究目的
To study the bending behavior of photovoltaic (PV) panels with a special boundary condition, focusing on their deformation under uniformly distributed force to ensure their safety and functionality in building integrated photovoltaic (BIPV) applications.
研究成果
The Hoff model and modified Rayleigh–Rita method provide accurate predictions of the bending behavior of PV panels under the studied boundary condition. The experimental results validate the theoretical and numerical models, showing that PV panels behave linearly elastically under the tested loads. The middle of the panel is identified as the critical point for maximum de?ection and stress, which should be considered in design and safety assessments for BIPV applications.
研究不足
The study focuses on a specific boundary condition (SSFF) and may not cover all possible real-world scenarios. The accuracy of the experimental results for thicker glass panels is affected by operational errors during the unloading process.
1：Experimental Design and Method Selection:
The study uses classical lamination theory (CLT) and a modified Rayleigh–Rita method to analyze the bending behavior of PV panels under a special boundary condition (two opposite edges simply supported and the other two free).
2：Sample Selection and Data Sources:
Double glass PV modules of two different thicknesses (2 mm and 3.2 mm glass) were tested under uniformly distributed water pressure.
3：2 mm glass) were tested under uniformly distributed water pressure.
List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: The test frame simulates the special boundary condition, and water pressure is used to apply uniformly distributed force. Strain measurement points are set on the panels, and de?ection is measured with a laser displacement meter.
4：Experimental Procedures and Operational Workflow:
The panels are subjected to increasing water pressure levels, with de?ection and stress measured at each level. The loading and unloading process is carefully controlled to ensure accurate measurements.
5：Data Analysis Methods:
The experimental data are compared with results from finite element analysis (FEA) using ANSYS and analytical solutions derived from the proposed equations.
