Extraction of Monocrystalline Silicon Photovoltaic Panel Parameters Based on Experimental Data

Abstract

The aim of this work is to develop models that reproduce highly precise I-V (Current-voltage) curves of photovoltaic (PV) panels, regardless of the temperature and sunlight conditions, using an experimental database installed at the PV PARK of Benguerir city, that allow the record an up to date current-voltage characteristics (I-V) of the PV. This paper presents three modeling approaches that simulate the PV arrays, two are classic models determined by the electrical behavior of the PV cell, while the last is based on experimental modeling us-ing the LUT (Look up tables) arrays and shows the performances results of the current-voltage characteristic obtained by the modeling approaches. To estimate the experimental parameters, we used the robust optimization algorithm Lev-enberg-Marquardt system, and a model based on the adaptive inference system ANFIS (Neuro-fuzzy adaptive inference systems) is developed to solve the problem of estimating of the experimental voltages V oc and V mp . We used MATLAB/ SIMULINK to build the mathematical model, and the experimental database is used to validate these models under Moroccan meteorological conditions.
