The tests were carried out using two rigid scale models according to the chapter 6 of the CIRSOC 102 code (method 3 - Wind tunnel procedure). The first of these models is called isolated and was built with a scale of 1:10. The second represents a sector of approximately 115 m × 115 m of the Cordillera Solar plant and it was built with a 1/200 geometric scale.Wind pressure measurements were made in the wind tunnel test section, where the wind velocity reaches 25 m/s. The mean and fluctuating pressure on the upper and lower surfaces of the modules were measured by means of an Scanivalve 96-channel system. Local pressure coefficients corresponding to the pressure taps were obtained. The tests were carried out using incident wind from 0º to 180º at intervals of 15º and 45º, since the models are symmetrical. Finally, the net force coefficients and the application point the force were calculated for each wind direction analyzed by the measured pressures.
