Performance analysis and reliability of grid-connected PV systems
in IEA countries
(2003)Zusammenfassung
This paper presents operational performance results of grid-connected
PV systems, as collected and elaborated for the Photovoltaic Power
Systems Programme of the International Energy Agency (IEA). Performance
ratios (PR) obtained from 334 PV installations in 14 different countries
are compared and discussed. In Germany, there is a significant rise
of PR between early installations in the nineties and new installations.
For Switzerland, BIPV and other types show high PR > 0.80, but average
PR values lower than expected were obtained. For Japan, lessons learnt
from the current monitoring programmes are used to improve PV system
performance showing constant performance at high level. As an outcome
of this work, reliable and worldwide monitoring performance data
and results are available for future developments of financing schemes
(e.g. feed-in-tariffs) in order to stimulate the PV market.
