The basic characteristics of ground effects in aerodynamic force acting on a photovoltaic panel in shear flow were studied based on the measurements in a grid generated turbulent flow and past measurements in shear flows. The aerodynamic force coefficients of a two-dimensional flat plate model were measured in a wind tunnel with varied height and angle of attack. The effects of turbulence were similar in both the grid generated flow and the shear flows. The effects of shear were more apparent in wind force coefficients that is the coefficient of the force component normal to the plate rather than moment coefficients. The wind force coefficents became smaller near the ground, but the effects were weakened by the existence of wind shear.
