Abstract

. To gain more solar energy the photovoltaic converter must be tracked relatively to the sun movement. The majority of the tracking systems use complicated and costly rotating mechanisms to build large angular strokes. This paper presents a new type of geared linkage composed of a triangular linkage fitted with a planetary gear pair able to reach high angular strokes. This linkage is used as basic mechanism for the azimuth tracking of a photovoltaic platform. The kinematic synthesis of the linkage shows that the azimuth angular stroke increases with the planetary gear internal ratio |i0|. The linkage is further implemented for an azimuth mono-axial tracked PV module located in a mountain location (case study - Brasov, Romania). Through numerical simulations, the amount of direct solar radiation on the PV module and the tracking efficiency are evaluated.
