In this article is evaluates the different tracking and search methods of the maximum power point (MPPT) in photovoltaic solar systems (PV), these methods are very extensive and use different algorithms, some of them based on artificial intelligence between others with the objective of finding the MPPT in a PV system consisting of a solar panel accompanied by a direct current to direct current (DC-DC) converter. There are five wellknown algorithms that find the MPPT with their respective characteristics, and are assigned rating values using the Entropy method by weight (EW) based on the Shannon Entropy; in the end of this work, is it gets a table of scores of these methods.
