Comparison of photovoltaic array maximum power point tracking techniques

Abstract—The many different techniques for maximum power point tracking of photovoltaic (PV) arrays are discussed. The tech-niques are taken from the literature dating back to the earliest methods. It is shown that at least 19 distinct methods have been introduced in the literature, with many variations on implementa-tion. This paper should serve as a convenient reference for future work in PV power generation. Index Terms—Maximum power point tracking (MPPT), photo-voltaic (PV). I
