Maximum power point tracking is a method to trap maximum available power from a solar panel. Many algorithms have been developed based on the characteristics of solar panel in order to utilize maximum available power. But these algorithms do not consider local maxima and minima in the solar panel characteristics caused due to shading. In this paper an enhanced version of Perturb and Observe maximum power point tracking algorithm is explained which also considers local maxima and minima caused by shading and makes the solar panel to work at its peak maxima. This helps in improving the overall efficiency of the system. Algorithm is implemented on 50W solar panel using ATMega 8 microcontroller and a boost converter.
