For an Ageing (degradation) general
description: see
Ageing, PV modules degradation
Main
dialog
When you open the Ageing tool (page
"Degradation" in the
"Detailed losses" dialog),
you have the following dialog:
| - Uses degradation in the simulation: |
when you check this option, the
simulation will be performed for the specified year. |
|
|
The report will mention the
operating year, the loss diagram will show the Degradation losses
at the module level, as well as the contribution of the evolutive
mismatch. |
| - Simulation for year: |
Specify the desired year. |
| - Global Degradation factor:
|
Average degradation factor for
the individual module, cumulated from beginning to the specified
year, |
| - Mismatch degradation factor: |
Cumulated Mismatch loss (as
computed by the Monte Carlo model) for the specified year,
|
General PV
module ageing parameters, used by the Monte Carlo model:
| - Average degradation factor:
|
Annual average factor (not the
extreme value from the datasheets), |
| - ISC dispersion RMS:
|
Width of the ISC dispersion |
| - Voc dispersion RMS: |
Width of the Voc dispersion. |
The dialog
shows a graph of the loss factors evolution according to these
parameters.
"Mismatch
calculation" page
On a
second page "Mismatch
calculation", you have the main conditions for the
calculation, as well as a numeric result of the mismatch loss along
the years.
| - Keep these MC values:
|
As the Monte Carlo is a
stochastic process, the results will be different at each
execution. This option allows to keep the calculated mismatch
curves within the variant. |
|
|
When checked, the options "ISC
and Voc dispersion RMS" are no more modifiable.
|
| - Read / Save model:
|
You have the opportunity of
saving the results as a model file, for use in another
project. |
"Module
warranty" page
The third
page "Module Warranty" defines
the conditions usually specified by the PV module manufacturer, as
well as the conditions of showing them on the graph (curve,
steps)
