The purpose of this work is twofold: first to investigate the accuracy of Photo-Voltaic (PV) modeling under non-standard test conditions (STCs), and then to estimate the inaccuracies on maximum power prediction for different PV technologies; this is achieved through the comparison between predicted and measured data under a variety of operating conditions. The developed technique is based on the identification of the modules parameters of the double-diode equivalent circuit. The model has been validated by experimental data taken on five different 2 kWp plants of the PV LABoratory (PV-LAB), with different interconnection schemes, and it predicts the power production for mono and poly crystalline Silicon (m-Si and p-Si) plants, while the prediction for CIGS and CdTe PV plants appears less accurate. Results of this comparison are then used to analyze the impact of prediction inaccuracy under real operating conditions.

Abstract
The purpose of this work is twofold: first to investigate the accuracy of Photo-Voltaic (PV) modeling under non-standard test conditions (STCs), and then to estimate the inaccuracies on maximum power prediction for different PV technologies; this is achieved through the comparison between predicted and measured data under a variety of operating conditions. The developed technique is based on the identification of the modules parameters of the double-diode equivalent circuit. The model has been validated by experimental data taken on five different 2 kWp plants of the PV LABoratory (PV-LAB), with different interconnection schemes, and it predicts the power production for mono and poly crystalline Silicon (m-Si and p-Si) plants, while the prediction for CIGS and CdTe PV plants appears less accurate. Results of this comparison are then used to analyze the impact of prediction inaccuracy under real operating conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
