Cumulated yield 25 years aprox

[tecnun]

Hello friends,

Is it possible to calculate cumulated yields for a certain number of years (eg 25) taking into account % degradation (eg 0,5%)?

It would be very useful for optimizing certain input field variables...

Thanks in advance

Best Regards

This is a topic that has also been requested, recently, in a different thread.

I reiterate the need for this feature. LCOE calculations rely on the lifetime production results, not just year 1.

Yes... but nobody answers anything about this request.

This is a development that we should do rather shortly indeed.

However it is not straightforward, this represents significant work for doing correctly. This will not be in the next main release.

Thanks André!

we ll be looking fwd to it

Thank you for your response, André.

It will be an important improve.

In order to calculate 25 year approx yield, I have been running a batch simulation where I increase the module quality loss by 0.5% per year and then run the simulation 25 times. This way only the modules are "degrading." I'd like to get some feedback on what you think about this approach.

Well the way I've been doing this is just assuming that in each year from year 1 to 25 the production will be 0.5% less than the last year. I know it's not precise but might give you an idea about what happens with your yeld. It's the same concept as NPV- Net present value.

Hello Dauslend,

How do you do it? I really dont know how to make 25 simulations in batch mode, as the csv file only "write" SIM_1 so when i simulate it calculates only one year...

Thanks in advance my best regards
