6 FAQs about [Factors affecting the deflection of photovoltaic brackets]

How to improve bifacial photovoltaic module deflection?

The increased weight can cause deflection of photovoltaic (PV) module, which may lead to decreased cell efficiency. In this study, we developed a deep neural network (DNN)-based finite element (FE) surrogate model to obtain the optimal frame design factors that can improve deflection in large-scale bifacial PV module.

What factors affect the bearing capacity of new cable-supported photovoltaic modules?

The pretension and diameter of the cables are the most important factors of the ultimate bearing capacity of the new cable-supported PV system, while the tilt angle and row spacing have little effect on the mechanical characteristics of the new type of cable-supported photovoltaic modules.

What is the maximum deflection of a PV module?

At this point, the maximum deflection of PV module was 12.3 mm, and the weight of frame was 3.2 kg, with a displacement of up to approximately 2.8 mm in the opposite direction occurring due to the reaction force caused by deflection from the support point to the end of the module.
