11.3.1.2.1 Define Output Losses
Calculation > Economic Efficiency Calculation > Technical Input > System output reduction due to age
(degradation)
Here you are able to define power loss in the PV modules caused by ageing.
Enter the annual Output Losses as a percentage of the nominal output (power rating). In
the Remaining Output column you will then see the resulting output as a percentage of
the nominal output. The Output Losses defined first take effect at the end of a period, ie
losses for the first year first come into effect in the second year, etc. After 10 years, the
power output of the PV module remains constant.
If you wish to allow for deviation in the first year of the PV modules’ actual output from the
nominal output, then enter this figure in the field labelled Deviation of Module Output
from Nominal Output.
