To obtain maximum power generation by PV plant thefollowing setting parameters of PV modules are essential:tilt angles, azimuth orientation, distances between modulerows. In this paper, the algorithm and the program inMATLAB for optimizing the tilt angle and azimuth ofreceiving surfaces are. The mathematical model is basedon maximization of the theoretical expression for the totalsum of solar radiation on the atilted surface. The experimentalhourly data for irradiance on a horizontal surface providedby meteorological stations are used as parameters. Transpositionto data on a tilted surface is carried out with aidsof anisotropic radiation models of Hay-Davies, Reindleand Klucher. The program allows calculating the optimalangles for any calendar operational period and any regionfor which the long-term radiation data are available. For astand-alone PV plant, the influence of the electric load andthe constrained battery capacity on the optimal tilt is considered.In the article the results of calculations for severalregions and typical calendar operational periods are given.
