Aerodynamic characteristics of a scale model of a concentrator photovoltaic system built near the ground were investigated for a wide range of yaw and attack angles. For smaller angles of incidence, aerodynamic forces are proportional to projected area in the transverse and lateral direction to the free stream. However, as the angles increase, separated shear layers reattach on the rear surface of the panel, and some deviations appear from the sine or cosine curve of the aerodynamic coefficients. Measurements revealed the effect of blockage by the ground on the aerodynamic forces and moment.
