The objective of this paper is to create a step-by-step tracking program which assures an increased energetic efficiency for a string of photovoltaic (PV) modules. This is achieved through various calculations, having as parameters: the solar angles, solar time, day of the year and turbidity factor, following to capture the maximum solar radiation, but with a small angular domain of the daily angle. For a motion law with high precision, the year is split into 8 time intervals and for each one it is found the optimum fixed elevation angle with the according daily angle field.
