4 Frequently Asked Questions about "Photovoltaic support equipment is unstable"

Do flexible photovoltaic support systems suffer from aerodynamic instability?

Flexible photovoltaic (PV) support systems have low stiffness, low damping, and may suffer from aerodynamic instability, especially fluttering, under wind loads. Reliable structural modal parameters are essential for studying aerodynamic instability.

What is flexible photovoltaic (PV) support?

Flexible photovoltaic (PV) support is a flexible support system composed of PV panels, flexible prestressed cables and steel rods, and so on. Compared with fixed PV support, it has the advantages of high headroom, large span, low cost and flexible site, etc.

Do PV inverters have stability problems on weak grid condition?

The corresponding equivalent grid impedance is rather large and easy to lead to stability problems of grid-connected inverters and many researches have been done focusing on the stability problems. In this study, a survey of stability problems of PV inverters on weak grid condition is given.

Why is flexible PV support better than independent PV support?

Compared with independent flexible PV support, the entire structure force performance and transfer mechanism of inter-row cables and inter-span rods of flexible PV support arrays are more complex, it is easy to have large vibration or even instability failure under strong wind.
