ABSTRACT A photovoltaic array (PVA) simulation model to be used in Matlab-Simulink GUI environment is developed and presented in this paper. The model is developed using basic circuit equations of the photovoltaic (PV) solar cells including the effects of solar irradiation and temperature changes. The new model was tested using a directly coupled dc load as well as ac load via an inverter. Test and validation studies with proper load matching circuits are simulated and results are presented here.

    • "An equivalent circuit model of photovoltaic cell with DC-DC boost converter is shown in Figure 4. The PV array is developed by the basic equations of photovoltaic cells including the effects of temperature changes and solar irradiation level [9] [10]. The output voltage of the PV cell is a function of photo current that is mainly determined by load current depending on the solar irradiation level. "

    • "The electrical system powered by the PV array requires DC–DC converter due to the varying nature of the generated solar power, resulting from sudden changes in weather conditions as shown in Table 3, which change the solar irradiation level as well as cell operating temperature. An equivalent circuit model of photovoltaic cell with low step-up DC– DC converter is shown in Fig. 4. The PV array is developed by the basic equations of photovoltaic cells including the effects of temperature changes and solar irradiation level [20] [21] [22]. The output voltage of the PV cell is a function of photo current that is mainly determined by load current depending on the solar irradiation level. "

    • "Many different studies have been conducted in the literature to obtain PV model [1] [2] [3] [4] [5] [6] [7] [8] that include single-diode model [1] [2] [3] and double-diode model [9]. Although doublediode model has the most accurate results; it includes too many parameters and complex expressions [9]. "

    ABSTRACT: A photovoltaic (PV) model is proposed on Matlab/Simulink environment considering the real atmospheric conditions and this PV model is tested with different PV panels technologies (monocrystalline silicon, polycrystalline silicon, and thin film). The meteorological data of Istanbul—the location of the study—such as irradiance, cell temperature, and wind speed are taken into account in the proposed model for each technology. Eventually, the power outputs of the PV module under real atmospheric conditions are measured for resistive loading and these powers are compared with the results of proposed PV model. As a result of the comparison, it is shown that the proposed model is more compatible for monocrystal silicon and thin-film modules; however, it does not show a good correlation with polycrystalline silicon PV module.
