6 FAQs about [Flexible photovoltaic bracket accident]

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.

Do Floating photovoltaic systems cause accidents?

Furthermore, despite previous experiments and numerical simulations, accidents have still occurred with floating photovoltaic systems. Fig. 1 shows a 2019 accident involving a floating photovoltaic system in Japan that was caused by a hurricane.

Do flexible PV support structures deflection more sensitive to fluctuating wind loads?

This suggests that the deflection of the flexible PV support structure is more sensitive to fluctuating wind loads compared to the axial force. 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.

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.

What is a Floating photovoltaic system?

Floating photovoltaic systems are usually installed on the coast or in a lake, so they are exposed to wave and wind loads. The structural design of the solar panels requires the calculated wind load, which is closely related to the wind speed, direction, and turbulence intensity (TI).

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.
