6 FAQs about [Photovoltaic bracket wind tunnel test model diagram]

What is a boundary layer wind tunnel test?

Boundary layer wind tunnel tests were performed to determine wind loads over ground mounted photovoltaic modules, considering two situations: stand-alone and forming an array of panels.

How are photovoltaic modules tested?

All tests were carried out using rigid models of the photovoltaic modules, that is, the experimental analysis is limited to static wind tunnel testing. A detailed numerical evaluation is performed using the finite element method (FEM) to identify critical structural sections.

What is the scale ratio of wind tunnel test model?

The geometric scale ratio of wind tunnel test model is 1:25. A building with size Lp×Bp×Hp = 20 m × 20 m × 10 m and flat roof is adopted in this study, and the scaled model size is Lm×Bm×Hm = 800 mm × 800 mm × 400 mm. PV panel arrays are arranged symmetrically along the center line of the building, and each row includes 16 panels.

Do panel array parameters influence wind load characteristics of PV panels?

In this study, the influences of panel arrays' parameters such as tilt angle and array spacing, as well as parapet height on wind load characteristics of PV panels are specially studied.

How can wind tunnel pressure be measured?

During the wind tunnel tests, the PV panel model was equipped with 28 pressure taps to measure the overall pressure distribution on the panel. Net aerodynamic force coefficients were determined from the simultaneous wind tunnel pressure time histories measured from upper and lower solar panel surfaces using the pressure integration method.

What is wind tunnel testing?

Wind tunnel testing is a key experimental method for the evaluation of wind effects on rooftop PV panels of lowrise buildings and most findings were incorporated in the ASCE 7-16 Standard.
