Abstract
This paper presents a numerical method for estimating four physical parameters of a single-diode circuit model
based on manufacturer’s datasheet. A system of four non-linear equations are formed based on three key
points of PV characteristics. The photocurrent, saturation current, ideality factor and the series resistance are
solved iteratively using the proposed method. The suggested method is validated using RTC France solar cell,
Chloride CHL285P and Photowatt PWP210 modules and the results are verified with respect to the in-field
outdoor measurements. The proposed method shows a good agreement with the experimental data. Lastly,
The model chosen is simulated under MATLB environment to assess the effects of external physical weather
conditions, that is, temperature and solar irradiance. The advantage of the proposed method with respect of
existing numerical techniques is that it converged faster than the widely used Newton method. Modeling of
PV cell/module is essential in predicting performance of photovoltaic generators at any operating condition.
