6 FAQs about [The distance between photovoltaic panels and parapet wall]

Does parapet height affect wind load of solar panels?

Wang et al (2018) studied the effects of parapet height on wind loads of solar panels on flat roof, and found that most critical positive peak pressure coefficients generally decrease with increase of parapet height. Meanwhile, Banks (2013) and Kopp (2014) claimed that conical vortices of buildings play a key role on wind effect of solar panels.

How does the parapet effect affect roof-top solar arrays?

Averaged ratios of peak uplift coefficients to no parapet case. The parapet effect on roof-top solar arrays results in peak wind load increases in all array zones. These increases are attributed to the impact on position, size, and strength of the vortices generated at the building corners.

Can a roof-top solar array have a parapet?

Designers should be cautious when determining wind loads acting on roof-top solar arrays with parapets present, particularly for parapet heights in the range of 1 – 7 Harray. Average peak loading increases of 1.7 times the no parapet case are possible.

Does roof height affect wind load of solar panels?

Stathopoulos et al (2014) studied wind effect on solar panels mounted on the roofs of 7 m and 16 m high buildings, and it was found that height of building has little effects on wind load of panels.

Do parapets shelter a solar array?

The corner vortices have been shown to dominate the peak wind loading of modules. The correlation between fluctuating pressures on top and bottom surfaces of the module is critical to the parapet effect. In general, there is no evidence that parapets shelter the array.

Does building height affect wind load on multi-row solar panels?

Kopp (2014) investigated wind load on Multi-row solar panels by adopting building with height ranging from 7.3 m to 21.9 m, influence of building height, aspect ratio and panels tilt angle on wind effect on panels are studied. Results show that wind loads do not obviously depend on tilt angle, for arrays with tilt angle of 10° and above.
