How safe are flexible PV brackets under extreme operating conditions?

Safety Analysis under Extreme Operating Conditions For flexible PV brackets, the allowable deflection value adopted in current engineering practice is 1/100 of the span length . To ensure the safety of PV modules under extreme static conditions, a detailed analysis of a series of extreme scenarios will be conducted.

How are photovoltaic modules tested?

All tests were carried out using rigid models of the photovoltaic modules, that is, the experimental analysis is limited to static wind tunnel testing. A detailed numerical evaluation is performed using the finite element method (FEM) to identify critical structural sections.

What is the design method for photovoltaic structures?

Currently, the design method for photovoltaic structures is based on controlling the stress at the limit state of bearing capacity and the displacement at the limit state of normal use. Therefore, Point 4 is selected as the analysis object for displacement wind-induced vibration response in this study.

What are the different types of photovoltaic mounting systems?

Apart from fixed photovoltaic brackets, tracking photovoltaic mounting systems are widely recognized as one of the most common types of PV support. Single-axis trackers (SATs) remain the economically viable option for developers in various situations and global locations when establishing solar farms , .

Which structural component is most important in photovoltaic module design?

For the case of the photovoltaic module array, it is observed that the wind loading over the leading panels is decisive for the design. According to the numerical results, the central support device is the most critical structural component. 1. Introduction Flow over inclined bluff bodies are of particular interest in wind engineering.

Does a flexible PV support structure exhibit a consistent response trend?

However, for mid-span acceleration, the wind suction condition results in greater values than the wind-pressure condition. Overall, it can be concluded that the flexible PV support structure exhibits a consistent response trend under both wind-suction and wind-pressure conditions. Figure 10.
