| Abstract: | The various technologies presented herein relate to providing prognosis
and health management (PHM) of a photovoltaic (PV) system. A PV PHM
system can eliminate long-standing issues associated with detecting
performance reduction in PV systems. The PV PHM system can utilize an ANN
model with meteorological and power input data to facilitate alert
generation in the event of a performance reduction without the need for
information about the PV PHM system components and design. Comparisons
between system data and the PHM model can provide scheduling of
maintenance on an as-needed basis. The PHM can also provide an approach
for monitoring system/component degradation over the lifetime of the PV
system. |
