A New Fuzzy-Based Maximum Power Point Tracker for a Solar Panel Based on Datasheet Values

الملخص EN

Tracking maximum power point of a solar panel is of interest in most of photovoltaic applications.

Solar panel modeling is also very interesting exclusively based on manufacturers data.

Knowing that the manufacturers generally give the electrical specifications of their products at one operating condition, there are so many cases in which the specifications in other conditions are of interest.

In this research, a comprehensive one-diode model for a solar panel with maximum obtainable accuracy is fully developed only based on datasheet values.

The model parameters dependencies on environmental conditions are taken into consideration as much as possible.

Comparison between real data and simulations results shows that the proposed model has maximum obtainable accuracy.

Then a new fuzzy-based controller to track the maximum power point of the solar panel is also proposed which has better response from speed, accuracy and stability point of view respect to the previous common developed one.
