Background: The solar field on our planet is inexhaustible, which favors the use of photovoltaic
electricity which generates no nuisance: no greenhouse gases, no waste.
Methods: It is a high value-added energy that is produced directly at the place of consumption
through photovoltaic (PV) solar panels. Notwithstanding these advantages, the maximum power depends
strongly on solar irradiation and temperature, which means that a Maximum Power Point
Tracking (MPPT) controller must be inserted between the PV panel and the load in order to follow
the Maximum Power Point (MPP) continuously and in real time. In this work, MPP’s behavior was
simulated at different temperatures and solar irradiations using seven techniques which identify the
MPP by different methods.
Results: The novelty of this work is that the seven MPPT methods were compared according to a
very selective criterion which is the MPPT efficiency as well as a purely digital duty cycle control
without using the PI controller. The simulation under the PSIM software shows that the FLC, TP,
FSCC, TG, HC and IC methods have almost the same efficiency of 99%, whereas the FOCV method
had a low efficiency of 96%.
Conclusion: This makes it possible to conclude that the best methods are FLC, HC and IC because
they use fewer sensors compared to the rest.
