About Standard value of flatness of photovoltaic bracket
Flatness The flatness of an optical element generally refers to the flatness accuracy of the element surface, which can also be expressed by local aperture, PV value (peak valley value), RMS (root mean square), power (defocus / astigmatism), PV (stable peak valley value), PSD (power spectral density), GRMS (gradient root.

The optimized main beam adopts a section height of 100mm, a section width of 36mm, and a section thickness of 2mm. Compared to the original bracket, the optimized bracket has reduced weight by 8.459kg, with a weight reduction rate of 14.45%.
Cable-supported photovoltaic (PV) modules have been proposed to replace traditional beam-supported PV modules. The new system uses suspension cables to bear the loads of the PV modules and therefore has the characteristics of a long span, light weight, strong load capacity, and adaptability to complex terrains.
the optimized bracket is reduced by 0.0531mm and the maximum stress is also reduced by 1.587MPa. This indicates that the solar panel bracket enhances the overall performance of the bracket while achieving lightweight. Keywords: Solar panel bracket; Ansys workbench; Finite element analysis; Response surface; Multi-objective optimization.
