Woluld be great an option to simulate in batch mode a long term period of time (i.e. all simulations for 20 or 25 years, for example), by increasing PV module degradation year by year automatically, and geneating pdf reports.

Regards.

I also agree, this would be very helpful for financial calculations.
I hope it is a planned feature.

Yes... this complete set of simulations is a very demanded info from financials. It wolud be very useful.

I use the module quality field in batch mode to simulate DC degradation over time. I dont get PDFs, but have a macro to assemble the csv files together into a spreadsheet.

It is an idea, but module quality is not the same than degradation. The behavior is different...

Totally agree! I was about to make the same suggestion... I have to estimate the system production over 20 years, and sometimes 2 or 3 different configurations, so I have to run 60 times and save 60 different files, with every loss number on them. And if by chance I notice that I made any mistake, I have to start from zero, it's a torture! :mrgreen:

I am doing at this moment 5 different configurations, for a period of 25 years each. This is 125 PVsyst simulations.
I patiently hope PVsyst developers would take this suggestion into account.

Here's a solution that fitted me! It gives slightly different results, but almost the same! ;)

Before a perform a simulation, I go to the "degradation losses" section and take note of all degradation and mismatch values for a given time horizon (in my case, 20 years), in a Excel spreadsheet. Then I untick the option to use degradation in the simulation.

Then I go to the batch simulation and change the variables "module quality" and "mismatch", and paste the values given in the spreadsheet.

But one should never forget the initial values (eg. if I use module quality -0.4% and mismatch 1%, these values have to be added every year)!

I don't know if I was clear enough, but if anyone have a question, feel free to ask!

Regards,
Rafael

From version 6.60, the Degradation (year number for a simulation and degradation parameters) is indeed part of the parameters you can use/modify in the batchs.

This is a really good news! Thanks a lot, André!
