The energetic efficiency of the PV panels can be sensibly increased using tracking systems. In their control program design the main parameters are the motions amplitude and the tracking steps number which are subject of optimization based on maximization of the received direct solar radiation on panel, on minimization of the driving energy for tracking, on PV type and on local meteorological conditions. In the paper, these parameters are analyzed for the azimuthal tracking, based on maximization of the received direct solar radiation on panel for a specific day and cloudless sky. An appropriate numerical simulation model, based on MatLab software, was implemented. The results and the correlations between the parameters, obtained for the daily orientation are in designing the seasonal and yearly tracking control program design.
