6 FAQs about [Requirements for the bending resistance of photovoltaic panels]

Why is bending behavior of PV panels important?

Which bending test is required for a PV module?

Only in the standard of PV module itself, IEC 61215 (2005) [ 9 ], the bending test under 2.4 KPa uniformly distributed force is required to all commercial PV module.

What is bending test of PV panel?

The bending test of PV panel is performed at room temperature to verify the structural analysis results aforementioned and detect the real mechanical properties. The 6 specimens are all the double glass photovoltaic modules (as shown in Fig. 9) which are provided by Suzhou Tenghui Photovoltaic Technology Co., Ltd (Changshu, P.R. China).

How big should a PV panel be under bending?

Since the width of the two steel beams and the frame cannot be ignored in that modified frame structure, the actual size of the PV panel under bending should be 1488 × 855 × 7.4 (unit: mm). And the later calculation and simulation should choose that size value.

Does classical lamination theory apply to bending behavior of solar panels?

Therefore, an accurate and systematic research on bending behavior of PV panels is important and necessary. In this paper, classical lamination theory (CLT) considering soft interlayer is applied to build governing equations of the solar panel.

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
