6 FAQs about [The role of photovoltaic panel vibration sensor]
Why do photovoltaic panels vibrate?
Strong vibrations occur when the wind speed is above a critical value. The vibrations of the windward panels are much stronger than the leeward panels. The Photovoltaic panels mainly vibrate at the first vertical and torsional mode. A suppression measure is proposed and successfully controls the wind induced vibration.
Do photovoltaic modules withstand mechanical vibrations?
Two logistics processes by road of different photovoltaic modules have been monitored to assess the harshness of the mechanical vibrations they are subjected to, including loading and unloading operations. Modules of different models and c-Si technologies, transported through different paths and packaged in different positions were tested.
Why do photovoltaic panels vibrate in a wind tunnel?
Photovoltaic panels supported by suspension cables is tested in a wind tunnel. Strong vibrations occur when the wind speed is above a critical value. The vibrations of the windward panels are much stronger than the leeward panels. The Photovoltaic panels mainly vibrate at the first vertical and torsional mode.
Can a cable-supported PV module control wind induced vibration?
A suppression measure is proposed and successfully controls the wind induced vibration. Photovoltaic (PV) modules are mainly mounted on the ground and on roofs. Recently, cable-supported PV modules have been proposed to replace traditional beams using suspension cables to bear the loads of the PV modules.
How to reduce vibrations on PV modules?
In order to eliminate, or at least reduce the vibrations on the PV modules, several strategies can be adopted. A first option could be to reduce the vibration transmission between truck structure and PV modules through the packaging.
How does wind speed affect the vibration of PV modules?
The vibration of the PV modules decreased in the leeward direction. In the center and leeward rows, R7 and R1 to R3, the vibration of the PV modules gradually and slightly increased with the increment in wind speed. In addition, both vertical and torsional vibrations were much higher than those in Case 0°.
