Comparison of traditional MPPT techniques for solar panels

With the increase in reliance on solar energy to produce electricity, so many maximum power point tracking techniques for photovoltaic panels were developed to maximize the produced energy and a lot of these are well established in the literature. These techniques vary in many aspects such as: simplicity, convergence speed, digital or analogical implementation, required sensors, cost, range of effectiveness, as well as in other aspects. This paper presents a comparative study of ten widely-adopted mppt algorithms; their performance is evaluated from energy point of view using the simulation tool (Matlab), considering different solar irradiance variations. Also, an economic evaluation has been made to make a comparison according to performance and cost, to determine the optimal choice.
