6 FAQs about [What are the factors of photovoltaic bracket deflection]

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.

Can a cable-supported PV system reduce vertical displacement?

Recently, the authors (He et al., 2020) proposed a new cable-supported PV system using three cables and four triangle brackets to form an inverted arch to reduce the vertical displacement of the PV modules.

What is the inflection point of a cable-supported PV system?

When the upward vertical displacement is less than 0.0639 m, the force first counteracts the self-weight of the cables and PV modules. Therefore, there is an inflection point at 0.0639 m. For the new cable-supported PV system, the lateral stiffness is much higher than the vertical stiffness.

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.

What is cable-supported photovoltaic (PV)?

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.
