In this paper, we analyze the shape, orientation and spatial distribution of microcracks in 41 different PV-modules with the aim to further investigate the impact of microcracks to the reduction of power output. A first very important result is that there is a good correlation between the percentage of inactive areas (black areas given by electroluminescence test) and the power variation with respect to the nominal power value measured in PV modules. More information has been provided by the position and shape of the microcracks in the PV module.

Abstract
In this paper, we analyze the shape, orientation and spatial distribution of microcracks in 41 different PV-modules with the aim to further investigate the impact of microcracks to the reduction of power output. A first very important result is that there is a good correlation between the percentage of inactive areas (black areas given by electroluminescence test) and the power variation with respect to the nominal power value measured in PV modules. More information has been provided by the position and shape of the microcracks in the PV module.File in questo prodotto:
