Abstract

BATISTA, C. R.  and  URQUIZA, R. I.. Calculation and analysis of the maximum annual efficiency of solar trackers. Entre Ciencia e Ingenieria [online]. 2018, vol.12, n.24, pp.25-31. ISSN 1909-8367.  https://doi.org/10.31908/19098367.3812.

A standard methodology is proposed in this work to calculate the efficiency of solar trackers for any geographical latitude. A literature review was performed, and related articles were selected. Following an analysis of the information, a dispersion of the reported results with respect to the mean value was identified. An algorithm was developed to calculate theoretical maximum energy efficiency, based on a scientific review of the concept of efficiency. The algorithm was programmed and ran according to the latitude in the reports. Maximum values of theoretical efficiency were obtained for each of the reported latitudes, presenting significant differences regarding the data presented by the authors. No clear methodologies for calculating the efficiency of solar trackers were identified in the articles studied. The proposed methodology be used as a reference, given that the real efficiency cannot be greater than the theoretical.

Keywords : Efficiency of solar tracker; maximum theoretical efficiency; methodology calculation; mobile support.
