10.3 Evaluation of the measuring results

The current/voltage characteristic curve (I/U characteristic curve)
of a photovoltaic system is used to identify and analyse different
features and problems of a generator. It helps detect partial shad-
ing of the generator field, defective bypass diodes, excessive ad-
ditional module resistance, soiling of the modules and problems
with individual cells in the PV modules. Interpreting characteristic
curves requires some experience and basic knowledge of semicon-
ductor technology. To facilitate the interpretation, examples of
characteristic curves from the evaluation software are compiled
at www.tri-ka.com.
