Abstract

This paper reports on the application of heuristic algorithms for one-dimensional bin-packing problems in solving current mismatch of concentrator photovoltaic (CPV) arrays that is caused by non-uniform solar flux distribution. As a case study, actual flux profile for a non-imaging planar concentrator (NIPC) is measured based on CPV cells´ location in a dense-array. Then, forty-four solar cells are reconfigured according to heuristic algorithm results. From this study, current mismatch is minimized from 1.03A to 0.07A resulting an increase in output power from 83.99W to 112.91 W. This reconfiguration method is tested by comparisons with Simulink current-voltage (I-V) curve results.
