ABSTRACT: Several studies on PV solar cells are found in the literature which use static models. Those models are
mainly one-diode, two-diode or three-diode models. In the dynamic modelling, a variable parallel capacitance is incorporated.
Unlike the previous studies which do not clearly establish a relationship
between the capacitance and the voltage, in the present paper, the link between
the capacitance and the voltage is investigated and established. In dynamic
modelling investigated in this paper, the dynamic resistance is introduced in
the modelling of the solar cell. It is introduced in the current-voltage characteristic.
The value of the dynamic resistance is evaluated at the maximum power point and its effect on the maximum power is
investigated. The study shows for the
first time, that the dynamic resistance must be introduced in the current-voltage characteristic, because it has
an influence on the PV cell output.
