EN The results of experimental verification of considerations conducted in [3] are presented, in terms of application single – axis tracking units, to increase the efficiency of the photovoltaic conversion, in comparison with fixed systems optimally oriented. The design and physical realization of a measurement stand is presented. A photovoltaic module inclination angle correlation algorithm, for a selected location and a measurement period, is described. The measurements were conducted in natural lighting conditions for different weather conditions. The current – voltage and power – voltage characteristics were compared for a fixed and vertically variable configuration. The value of the electric energy generated by tested photovoltaic modules in both cases was determined.
