PVsyst Hourly Data Export as P90

[WCrockett]

Hi,

I see that the Energy to Grid values add up to be the P50 value for Hourly and Monthly data in the Advanced Simulation section.

Is it possible to simulate and generate Energy values that add up to be the P90 or P95 total values? If it is not, can you show how to calculate these values in Excel?

Thank you.

Hello,

The P90 statistical estimations are based on yearly values. P90 for hourly or daily values (or even for monthly accumulations) doesn't provide meaningful results due to the high variability of short-term weather patterns.

Kind regards
