The invention relates to a suitable control method for a system of photovoltaic concentration modules, which can be used to maintain the correct orientation of the modules in order to track the sun without requiring the use of positioning sensors. The sun is tracked by performing angular movements in relation to each of the degrees of freedom at given intervals, measuring the power or current supplied by the energy collection module(s). The estimation of the sun's position and the strategy for subsequent movements are determined as a function of the reading.
