Abstract

In this paper a complete model of a-Si:H single junction module operating in partial shading conditions is presented. It is based on the typical single-diode model, properly adjusted for reversed operation and enhanced by a term describing the recombination phenomenon. Both single and multi-string modules are studied at partial shading operation and compared on power production and shaded cells voltage level. The simulation results are experimentally validated by measurements on two modules at various shading patterns.
