On the evaluation of wind loads on solar panels: The scale issue
TL;DR: In this paper, the authors investigated the geometric scale and the inflow turbulence characteristics as potential causes of high uncertainties in wind tunnel data and proposed a proper testing protocol to eliminate such discrepancies in the test results and to allow for accurate wind load estimation.

Wind loads on photovoltaic arrays mounted parallel to sloped roofs on low-rise buildings
TL;DR: In this paper, the effects of geometry on the wind loads acting on photovoltaic panel arrays with modules mounted parallel to the roof surfaces of low-rise buildings were investigated, and it was found that larger gaps between modules, G, and smaller gaps between the panels and the roof surface, H, were found to yield lower net wind loads.

Wind loads on residential scale rooftop photovoltaic panels
TL;DR: In this article, large-scale models of rooftop photovoltaic (PV) panel arrays on residential buildings were tested in the Wall of Wind Research Facility and the results revealed that the critical wind directions that induced the worst maximum and minimum peak force coefficients were depended on roof type and panel tilt angle.
