Theoretical efficiency of a gear based azimuthal tracked photovoltaic platform

The paper presents the results of a theoretical analysis developed to estimate the energy produced by an azimuthal tracked photovoltaic (PV) system. The mechanical structure of the tracking system is build up by a worm gear serial connected to a double straight bevel gear. Sun tracking is attained through the sun’s trajectories tracking method. There are presented, simulated and comparatively analysed 5 series of tracking programs, characterized by different numbers of annual intervals and of the step performing intervals. The analysis is made in the hypothesis of clear sky for Braşov – Romania geographical coordinates: 45.65°N latitude, 25.58°E longitude. The conclusions can be directly used in the implementation stage of the optimum tracking program, to experimentally verify the energetic response theoretically estimated.
