How does the tilt angle affect a solar panel?

As the solar panel tilt angle increases from 0° to 60°, the support reaction wind-induced vibration coefficient (βz_f) ranges from 1.07 to 1.67, and the displacement wind-induced vibration coefficient (βz_u) ranges from 1.70 to 1.93, showing a clear impact of the tilt angle on these coefficients.

How does a tilt angle affect a PV system?

A change in the tilt angle simultaneously leads to a change in the amount of radiation reaching the surface of the PV panels . However, as a general rule, the tilt angle for a PV array installation is nearly equivalent to the latitude of the area [90,91].

Do panel tilt angles influence support reactions and displacement wind-induced vibration coefficients?

Quantitative exploration reveals distinct influences of panel tilt angles on support reactions and displacement wind-induced vibration coefficients in FCSPSs.

How does tilt angle affect wind pressure distribution?

As the wind pressure gradually increases, the variation in the wind pressure distribution tends more stable with the increase in tilt angle. The shielding effect on the mean wind pressure coefficient of the flexible PV support structure is most pronounced in the second row of the windward zone.

Does tilt angle affect wind tunnel vibration?

Xu and his team further conducted wind tunnel tests using aeroelastic and rigid models, showing that the vertical vibration of flexible cable-supported PV systems increases significantly with the tilt angle, and that the gust load coefficient of PV panels with a tilt angle of 10° ranges between 1.2 and 2.5.

Does tilt angle affect wind-induced vibration coefficients?

The results indicate that the tilt angle has a certain impact on wind-induced vibration coefficients (reaction force, displacement). The effect of the tilt angle on the internal force wind-induced vibration coefficient is more pronounced.
