Analytical modeling of current-voltage photovoltaic performance: an easy approach to solar panel behavior
2021
In this paper, we propose very simple analytical methodologies for modeling the behavior
of photovoltaic (solar cells/panels) using a one-diode/two-resistor (1-D/2-R) equivalent circuit.
A value of a = 1 for the ideality factor is shown to be very reasonable for the different photovoltaic
technologies studied here. The solutions to the analytical equations of this model are simplified
using easy mathematical expressions defined for the Lambert W-function. The definition of these
mathematical expressions was based on a large dataset related to solar cells and panels obtained from
the available academic literature. These simplified approaches were successfully used to extract the
parameters from explicit methods for analyzing the behavior of solar cells/panels, where the exact
solutions depend on the Lambert W-function. Finally, a case study was carried out that consisted of
fitting the aforementioned models to the behavior (that is, the I-V curve) of two solar panels from the
UPMSat-1 satellite. The results show a fairly high level of accuracy for the proposed methodologies.
