Estimation of the series resistance (Rs) is an important factor to detect degradation on photovoltaic (PV) systems. Currently, there are several methods to estimate Rs of a PV module. However, the accuracy is still not satisfactory. Therefore, this study has validated the estimation accuracy using the conventional method of calculating the slope of a current–voltage (I–V) characteristic. The results indicated that the Rs was overestimated. Therefore, the equivalent circuit equation was used in an attempt to improve the accuracy. The result showed that Rs can be estimated accurately by using a slope of a single I–V characteristic.
