6 FAQs about [Photovoltaic panels deflected by strong winds]

Do different roof types affect the net wind load of PV panels?

Different roof types cause different flow patterns around PV panels, thus change the flow mechanism exerted on PV panels. In this study, the effects of roof types, heights and the PV array layouts on the net wind loads of the PV panel is investigated.

How does wind load affect photovoltaic panels?

The wind load on the photovoltaic panel array is sensitive to wind speed, wind direction, turbulence intensity, and the parameters of the solar photovoltaic panel structure. Many researchers have carried out experimental and numerical simulation analyses on the wind load of photovoltaic panel arrays. Table 1.

Do flat roof PV panels have a high wind load?

They discovered that the wind load coefficient rose as the panel line spacing increased, while the wind load of the roof array decreased as the building edge perimeter spacing increased. Cao et al. carried out several wind tunnel tests to assess the wind stresses on flat roof PV panels.

How to reduce the impact of wind on photovoltaic structures?

At present, they do not provide comprehensive guidelines for reducing the impact of wind on photovoltaic structures. The present study contributes to the evaluation of the deformation and robustness of photovoltaic module under ocean wind load according to the standard of IEC 61215 using the computational fluid dynamics (CFD) method.

Do roof-mounted PV panels have a wind flow mechanism?

The wind flow mechanism related to the wind loads of the roof-mounted PV array was researched by Kopp et al. (2012) taking into consideration of two panel tilt angles. A wind tunnel experiment conducted by Cao et al. (2013) evaluates the wind loads on PV panels located on a flat roof.

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.
