6 FAQs about [Reasons for bending of glass photovoltaic panels]
Is double glass PV panel bending?
In present paper, the bending behavior of double glass PV panel is studied carefully by both experimental and theoretical research. Different from many previous researches, a special boundary condition which is two opposite edges free and the other two edges simply-supported (annotated as SSFF) is considered.
Why is bending behavior of PV panels important?
The wind and snow pressure are the usual loads to which working PV panels need to face, and it needs the panels keep undamaged under those pressure when they generate electricity. Therefore, an accurate and systematic research on bending behavior of PV panels is important and necessary.
How bending experiments are used in PV panels with two boundary conditions?
The bending experiments of PV panels with two boundary conditions are used to verify the accuracy of the proposed solutions. Finally, the influence of different boundary condition is stated by comparing the numerical results and some guides for the PV panel installation are proposed. 1. Introduction
How bending testing is performed for photovoltaic panels?
In order to verify the structural analysis results and test the real mechanical properties of PV panels, bending testing is performed for 8 specimens at room temperature. The specimens are all the double glass photovoltaic modules (as shown in Figure 3) which are provided by Suzhou Tenghui Photovoltaic Technology Co., Ltd (Changshu, China).
Which model is used to describe bending behavior of PV panel?
The Hoff model is adopted in this research to describe the bending behavior of PV panel. By using a modified Rayleigh–Rita method, a closed form solution is derived out and a calculation program is made for the PV panel with the special boundary condition. In experimental works, the special boundary condition is realized by a specific frame.
Which closed form solution should be used for PV panel bending?
The closed form solutions are obtained for PV panel with two boundary conditions. The bending behaviour of PV panel is studied by some improved tests. Deformation is linear and nonlinear in PV panel with SSFF and SSSS, respectively. SSSS should be considered as the primary choice in BIPV projects.
