On the PV Module Characteristics Conference Paper uri icon


  • © 2016 IEEE. Photovoltaic (PV) renewable energy resources are of interest for researchers today. An investigation of the PV characteristics is useful to understand its behavior. In this paper, the characteristics of the PV module have been explored and analyzed for different values of temperature at constant insolation (1kW/m2), and with different values of irradiance at constant temperature (25°C). Moreover, the characteristics of the PV module have been compared to an ideal voltage source in many cases by varying the ripple and average value of the PV voltage, current and power. The maximum power point (MPP) of the PV module is found graphically and analytically. Then, the duty ratio at which the PV module operates at maximum power, effect of changing the inductance value and switching frequency are explored for the PV voltage, current and power. The results show that the PV module behaves like an ideal voltage source at the MPP in case of average value comparison. Furthermore, the two sources have approximately the same ripple current. The effects of increasing the inductance value as well as the switching frequency values are investigated. As the inductance value and frequency increase, this will give very low ripple current, voltage and power, and thereby a better approximation for the MPP.
