6 FAQs about [Photovoltaic support tilt test]

What is the tilt angle of a photovoltaic support system?

The comparison of the mode shapes of tracking photovoltaic support system measured by the FM and simulated by the FE (tilt angle = 30°). The modal test results indicated that the natural vibration frequencies of the structure remains relatively constant as the tilt angle increases.

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 can modal testing improve tracking photovoltaic support systems under different tilt angles?

Through field modal testing and finite element modal analysis, this study enables us to obtain dynamic parameters of tracking photovoltaic support systems under different tilt angles, including modes, damping ratios, and vibration patterns.

Do tilted flat PV panels increase wind load?

Banks et al. investigated the uplift wind loads on the roofs of wide, rectangular, low-rise, flat-roofed buildings using tilted flat PV panels in an atmospheric boundary-layer wind tunnel. The findings showed a significant difference in wind load between the corner vortices and the cases without them.

Do wind-induced vibration of PV modules increase with tilt angle?

Results show that wind-induced vertical vibration of the PV modules increased with tilt angle but reduced with increasing cable pretension. The fluctuating displacement shows a quasi-linear increase with the square of the wind speed. Negative aerodynamic damping was found for a tilt angle of 10° under high wind speeds.

Does tilt angle affect aerodynamic response of PV structure?

During the test, two tilt angles (α = 0° and 10°) and two initial pre-tensions (F = 120 N and 150 N satisfying the requirement of maximum sag ratio less than 1/200 as per the code JGJ 257–2012 ), were examined to show their effects on the aerodynamic response of the PV structure.
