An Improved Method to Predict the Position of Maximum Power Point During Partial Shading for PV Arrays

For a photovoltaic (PV) system, it is widely assumed that the peaks of a partially shaded P-V curve are located at the multiples of 0.8Voc, where Voc is the open-circuit voltage of the PV module. However, this assumption - known as the of 0.8Voc model for partial shading - is not necessarily true. If the same model is used to design the maximum power point tracker (MPPT), it is very likely that th...
