6 FAQs about [Photovoltaic bracket static oscillation test specification]

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.

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.

What is a fixed adjustable photovoltaic support structure?

In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed.

Can a crystalline silicon PV module be tested with a continuous sun simulator?

No: Modification according to the IEC TS 62915: Test programs for crystalline silicon PV modules Supplementary information: Continuous Sun Simulator. x = 0.01 shall be used for crystalline silicon PV modules. ------------------ End of the Test Report n.

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 wind-vibration coefficient should be used for flexible PV support structures?

Considering the safety of flexible PV support structures, it is reasonable to use the displacement wind-vibration coefficient rather than the load wind-vibration coefficient. For the flexible PV arrays with wind-resistant cables discussed in this study, a recommended range for the wind-vibration coefficient is 1.5 to 2.52.
