Modeling of photovoltaic module and experimental determination of serial resistance

An explicit model is presented for accurate simulation of the I-V curve characteristic of photovoltaic (PV) module. The model is compared with the traditional I-V curve characteristic and to some experimental results to show the accuracy of the method. The explicit model proposed is found to be reliable and accurate in situations where this model is a good approximation of cell or module performance. Also, an experimental method is presented to determine the series resistance and shunt resistance of the PV cells and PV modules.
