目前市场上存在的光伏（PV）面板是一种层压板结构，由两层硬质玻璃表皮和一层软质夹层组成。其中一些面板安装在建筑物上并集成为结构的组件，例如墙壁和屋顶。在不同的地点，面板的安装是不同的，并且不再简单地支持边界条件。电池板的发电要求需要其机械行为在任何边界条件下都是稳定的。本文分析了不同边界条件下光伏电池板的弯曲行为，并仔细研究了边界条件的影响。采用经典层压理论（CLT）之一的基尔霍夫理论建立静力作用下光伏板的控制方程。改进Rayleigh-Rita方法来求解控制方程并计算静态变形和应力。不同的边界条件需要对偏转函数进行不同的假设，并且开发了修正的通用函数来解决该问题。推导出理论解并用于数值计算。通过对两个相对边缘简支、另外两个自由的光伏电池板进行弯曲实验来验证所提出解决方案的正确性和准确性。最后，通过比较数值结果来说明不同边界条件的影响，并提出一些光伏电池板安装指南。
The photovoltaic (PV) panels currently existed on market are a kind of laminated plate structure, which is composed of two stiff glass skins and a soft interlayer. Some of those panels are installed on the buildings and integrated as the components of the structures, such as wall and roof. In different locations, the installations of the panels are different and the boundary conditions are not simply supported any more. The generating electricity requirement of the panels needs the mechanic behaviour of them is stable with any boundary condition. In this paper the bending behaviour of PV panels with various boundary conditions is analysed and the influence of boundary condition is studied carefully. The Kirchhoff theory which is one of the classical lamination theory (CLT) is adopted to build governing equations of photovoltaic panels under static force. A Rayleigh-Rita method is modified to solve the governing equations and calculate the static deformation and stress. Different boundary condition requires different assumptions of the deflection function and a modified general function is developed to solve that problem. A theoretical solution is derived out and used to do the numerical calculation. A bending experiment of PV panel with two opposite edges simply supported and the other two free is used to verify the correctness and accuracy of the proposed solution. Finally, the influence of different boundary condition is stated by comparing the numerical results and some guides for the PV panel installation are proposed.
