Which material is idealized to a PV module?
The PV module is idealized to a stack having a superstrate of 0.7 mm EXG® glass, Crystalline Silica (cSi) wafer (0.2mm) sandwiched between EVA encapsulant (0.5mm) and a substrate of Soda Lime Glass (3.2mm). The material property of each of the layers is given in the Table 1.
How do PV panels work?
In the direct method, typically, PV cells are sandwiched between two glass substrates and the sandwich panel is installed and positioned towards sunlight. The PV panel is subjected to rigorous loading cases designed to predict the mechanical reliability before it can be approved for a commercial use.
What are the optimal design parameters for a glass-glass PV module?
This study finds the optimal design parameters of the support structure consisting of two C-Chanel that support the Glass-Glass PV module having thin glass on top and SLG at the bottom. Based on analysis described here, it was found that optimal channel location from free edges is close to L/5 that gives mechanical reliability of 0.99.
