To clarify the influence of near-ground wind fields on tracking photovoltaic （PV） structures， wind tunnel tests and Computational Fluid Dynamics （CFD） simulations are conducted in this paper for the analyses of shielding effects and shape factors under different tilt angles， wind direction angle， and height of PV arrays. Building upon this analysis， the paper investigates the impact of shielding effects of multi-row PV arrays on the values of shape coefficient under different wind direction angles. Results show that the surface wind pressure of a single-row PV component follows a trapezoidal distribution. For multi-row PV arrays， as the tilt angle increases， the shielding effects increase significantly. The shape coefficients tend to be stable when the number of upstream PV arrays becomes large. The height of their heights has a certain impact on the shape coefficient of both individual PV components and arrays.
