Abstract:
In these days the diagnostic about the state of health of PV module is done
through EL and IRT imaging. These techniques are quite expensive and at the time very
difficult to perform. Practically very little research has been done to certain to find out
the state of health of PV Modules through MPPT. The key objective of this thesis is to
propose a method that can predict the possibilities of any defects in string inverter
architecture. The MPPT algorithm proposed in (REF) is used to find the presence of
defective module in a PV string. The MPPT algorithm in (REF) is extended to utilize
for the purpose of diagnosis.
