Equilibration algorithm for maximum power point tracking in solar panels

Solar irradiation that hits the photovoltaic modules has a variable character depending on the latitude of the earth, sun angle etc. The energy produced by the PV modules depends on the irradiation and temperature. Thus the changing environment creates a necessity to identify the point for every instant on the IV characteristics of the PV generator in which there is the maximum amount of power transfer from the source to the load. Proper tracking algorithm is needed to achieve the maximum power from the PV cell. In this paper, a new methodology called Equilibration Algorithm is proposed. This algorithm is formed by extracting the essence of two different conventional algorithms called incremental conductance algorithm and relative position algorithm. The algorithm gives good convergence speed and less hardware complexity. Thus, the advantages of the Equilibration algorithm has been compared and verified.
