6 FAQs about [Investigation of photovoltaic brackets]

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.

Should a photovoltaic design consider a large deformation effect?

It is recommended that practical photovoltaic engineering designs fully consider the large deformation effects of the cables.

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 , .

Why are flexible PV mounting systems important?

Traditional rigid photovoltaic (PV) support structures exhibit several limitations during operational deployment. Therefore, flexible PV mounting systems have been developed. These flexible PV supports, characterized by their heightened sensitivity to wind loading, necessitate a thorough analysis of their static and dynamic responses.

Are flexible PV support structures prone to vibrations under cross winds?

For aeroelastic model tests, it can be observed that the flexible PV support structure is prone to large vibrations under cross winds. The mean vertical displacement of the flexible PV support structure increases with the wind speed and tilt angle of the PV modules.

Why are pre-stressed flexible cable-supported photovoltaic systems becoming more popular?

With the increasing adoption of mountainous photovoltaic installations, pre-stressed flexible cable-supported photovoltaic (PV) systems (FCSPSs) are becoming increasingly popular in large-scale solar power plants due to their evident adaptability to sloping terrain. The wind-induced deformation of FCSPSs significantly influences the wind field.
