The development of photovoltaic (PV) energy throughout the world this last decade has brought to light the presence of module mismatch losses in most PV applications Such power losses, mainly occasioned by partial shading of arrays and differences in PV modules, can be reduced by changing module interconnections of a solar array This paper presents a novel method to forecast existing PV array production in diverse environmental conditions. In this approach, field measurement data is used to identify module parameters once and for all The proposed method simulates PV arrays with adaptable module interconnection schemes in order to reduce mismatch losses The model has been validated by experimental results taken on a 2 2 kW(p) plant, with three different interconnection schemes, which show reliable power production forecast precision in both partially shaded and normal operating conditions Field measurements show interest in using alternative plant configurations in PV systems for decreasing module mismatch losses (C) 2010 Elsevier Ltd All rights reserved
