Solar energy is one of the most important renewable energy, and it will not cause pollution and damage to the environment, using PV solar energy collection devices to generate electricity for
Currently, the photovoltaic (PV) panels widely manufactured on market are composed of stiff front and back layers and the solar cells embedded in a soft polymeric interlayer. The wind and snow pressure are the usual loads to which

In Fig. 12 a clear portrait of stress vs. structural deformation has been plotted to show that how structural deformation is increasing linearly when stress is building inside a PV panel. Overall view of maximum internal stress vs. maximum total deformation when the wind speed is varying from 10 to 260 km/h
Delamination is highly the lifetime of photovoltaic panel. This kind of delamina- tion is extremely dependent on internal stresses. This type of stress is called peeling stress. It has been observed from the panel. As the deformation increases the internal atoms. Due to huge pressure and stress the structural

It means there is no residual deflection and so the whole deformation is an elastic deformation. After the test, all the specimens were checked carefully and there was not nay cracks or breakages on the surface glass. Therefore, the whole deformation of PV panel during the test is a linear elastic deformation.
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. The proposed method is better in small deformation range and maximum deflection.
