Abstract

A simple indoor hot spot test procedure for photovoltaic modules is described. Different cell connection configurations are considered : the simplest case of a single series string and more complex mixed serial parallel connections. For each configuration the proper test procedure is suggested. Typical results of tests of nearly eighty modules are reported. Scanning electron microscope experiments and chemical analysis have been performed to identify the basic phenomena which give rise to hot spots. Correlation between localized heating and visible light emission centers characterized by the presence of field concentrating defects (metallic impurities) has been found.
