HELP!!! Estimation P50-P90

[alejolop1]

Hi guys, I hope you can help me. I find myself making the estimate of probabilities for a plant, but I must do it year by year for 25 years.

my question is: With what values should vary the following uncertainties year by year (during the 25 years)

- PV modules model and parameters (the main uncertainty after Meteo)

- Inverter efficiency (negligible)

- Soiling and module quality loss (highly depending on the site conditions)

- Long term degradation

thanks!!!!!!

These are not significant. You can let all these values to 0.
