PV panel current-voltage curves provided by measurement devices usually suffer from noise and other inaccuracies such as uneven distribution of the measurement points. This might complicate the curve fitting process by deteriorating the fit quality and making the diagnosis based on the curve misleading. This paper provides a stepwise preprocessing method for PV panel measured current-voltage curves. The method improves the quality of the measured current-voltage characteristic data, which has been verified by examining its effects on the fitting process.
