Modelling and Optimization of A CPV System with Equatorial Tracking

Abstract

The paper presents research on modeling the influence of an equatorial tracking system on the efficiency of a low-concentrated Photovoltaic (CPV) system build-up of a PV module and two mirrors. This work sets the influences of the tracking system, the tracking accuracy, and the geometric parameters on the tracking efficiency of a CPV system. The main objectives of the paper are: to maximize the tracking efficiency of the direct radiation, to minimize the overall size of the CPV system, and to compare the equatorial to the previously discussed pseudo-equatorial tracking system. The geometric modeling and the numerical simulations allow the identification of the optimal solutions.
