AN ANALYTICAL MODEL FOR MISMATCH LOSSES IN PV ARRAYS

Abstract
Variations in the I-V characteristics of photovoltaic modules can lead to significant power loss. This study deals with an analysis of series-string losses. The current parameter of a set of PV modules is considered as a random variable following the Weibull distribution. An analytical expression has been obtained to predict these losses. A preliminary experiment that shown a good agreement with the proposed model is also presented.
