In this paper a direct method to estimate maximum power points (MPPs) in PV arrays subjected to mismatching conditions is presented. The method uses the lossless single-diode model (SDM) which is parameterized using the data of inflection and maximum power points of each panel. The reconstruction of power vs. voltage curve is obtained by one explicit equation, thus avoiding the use of recursive non-linear equations solver. The performance of this technique has been validated in terms of computation time and accuracy by means of the comparison with other existing methods.
