TThe differences between single diode model and double diode models of a solar photovoltaic cells: systematic review. Journal of Engineering, Technology, and Applied Science (JETAS), 5(2), 57-66.2721-8090https://dir.muni.ac.ug/handle/20.500.12260/564This research paper systematically reviewed and investigated single diode model and double diode model of a solar photovoltaic systems in terms of accuracy, differences under major unknown PV parameters, different optimization and fabrication. This research paper reviewed the differences and the similarities between the single diode model and double diode model. From the review, it was clear that single diode model has less computation time and number of unknown parameters compared to double diode model. The double diode model on its own superiority is more accurate under solar shading condition effect than single diode model but single diode model performs better under high insolation levels. None of the two models is superior than the other but the solar photovoltaic modelers/installers should bear the solar irradiance of the environment before installation.enDouble DiodePhotovoltaicRenewable EnergySingle DiodeSolarArticle
