It was shown that the mounting configurations impact both the static (deformation and strength) and dynamic performance (dynamic characteristics and responses). Moreover, the observed deformations and stresses were large enough to cause cracks in the solar cell wafer or even damage to the whole PV module.
stallations of PV panels are different and the boundary conditions are not always simply supported. 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 is adopted to build governing equations of PV panels under static .
The nonlinear elastic behavior of solar panel is predicted by the closed form solution. Simple support and clamped support are considered for deflection prediction. The sensitivity of the spring coefficient to the beam deflection is illustrated.
Proper controlling of aerodynamic behavior ensures correct functioning of the solar panel. Due to extreme pressure, delamination of interfaces happens inside the photovoltaic panel.
