Detailed effects of wind on the field performance of a 50 kW CPV demonstration plant

Abstract

The effect of the wind speed and direction on the arrays in a 50 kW plant was analyzed along several days. The wind is measured in different positions of the plant: the general plant meteorological station, the module's boundary layer and the close surroundings of the array. The averaged thermal resistance between the back of the module and the ambient is calculated and its dependence with the wind direction analyzed. Early results suggest that Northern wind has a better cooling effect than Western and Eastern winds.
