Abstrakt
The on-grid photovoltaic system was installed at the Faculty of Engineering in 2015.
The monitoring system developed in our laboratory monitors data and can also detect failure and
type of failure. The evaluation of the data shows that the amount of electricity produced slightly
exceeds the expected values predicted by the internationally used internet application PVGIS.
The effect of the aging of PV panels has so far had a minimal effect on the electricity produced.
Immediate output power is affected by multiple parameters. Higher temperatures reduce the
efficiency of energy conversion, so in summer the instantaneous power may be lower even at
higher radiation intensity and smaller angle of incidence.
