This study presents a new method for controlling the flow rate of a fluid by enslavement of the circulator in the stand alone production systems of heat using solar energy (PV/Th). The electronic control developed using this method allows to adjust in real time the speed of the circulator for converge to the needed set by the user and/or maximize the energy exchange (following the sun) between the solar collectors and the use. It will be presented here the results obtained with stand alone solar collectors using air as a heat fluid.
