Single diode PV circuit models have been used widely in the literature for their simplicity. Although they are sufficiently accurate at standard test conditions (STC), they exhibit deteriorated accuracy at low levels of irradiances. This paper enhances the accuracy of single diode models at lower irradiances without affecting their simplicity. It modifies the saturation current equation to improve the accuracy under irradiance variations. The accuracy improvement is demonstrated by comparing

His research interests include smart grids operation and control, power quality, distributed generation, power electronics, digital signal processing applications to power systems, and mechatronics. This paper is a revised and expanded version of a paper entitled 'Improving the accuracy of the single diode PV models at low irradiances' presented at IEEE
