3.Dynamic irradiation
-
- In the previous slides it is shown
that even during minor shading effects, systems with ac-modules will
outperform system with string
systems
-
- But also in non-shaded systems the
output of PV-modules may vary
(paper Roland Brundlinger, Staffelstein 2008)
-
- For example on a cloudy day the
irradiation changes continuously when clouds are passing by.
-
- In the study of Roland Brundlinger
it is shown that in Austria roughly
50% of the power is collected during days with large changes in irradiation.
-
- The next two slides are taken from
his presentation.
