ABSTRACT
In the paper, the effects of shading on copper indium gallium selenide (CIGS) solar modules are presented.
The influence of different degrees of shading of CIGS thin-film PV modules on their performance is analyzed
after measuring their I-V and power characteristics. The results show that even small shading significantly af-
fects the efficiency of the modules.
