Abstract :
A well-known limitation of the perturb and observe (P&O) MPPT method is that it can get confused and track in wrong direction during rapidly changing irradiation. The present work offers a simple and effective solution to this problem, by using an additional measurement of the solar array´s power in the middle of the MPPT sampling period. The method has been experimentally tested and compared with the traditional P&O method
