Abstract

The concentrator photovoltaic (CPV) systems work to their highest efficiency only when they are provided with a tracking system of high accuracy. The sun ray’s projections on to an equatorial plane, with the primary angles have been extended on the other two planes of a polar/equatorial reference system. Three pairs of solar angles are discussed and analytically modeled. Based on these angles new tracking mechanisms have been generated and comparative analyzed by numerical simulations.
