Power generation data of Probability (P90,P70 etc)

[Lunatic09]

Q1 Is there any way to achieve the power generation data of probabilities such as P90, P70

Q2 How to connect arrays with different tilt and azimuth to 1 inverter ?

The P50 - P90 concept is explained in the help "Project design > P50 - P90 evaluations"

It is a probabilistic interpretation of your simulation result. It is only applicable to an annual result.

You can connect at most 2 orientations on an inverter input. Please define these 2 orientartions, and you can choose (Mixed orientations 1 + 2) in the sub-array.

NB: All module of each string should be in the same orientation. You cannot mix orientations within a string.

Thank you for your response,

Do you have a plan to support a hourly data output of Probability ?

And I tried mixed orientation system setting, I can only adapt mixed #1, #2 but other #3, #4 can't adjust

If I have 4 mixed orientations, how can I set up 2 inverter with #1,#2 and #3,#4?

Should I simulate project separately ?

Can I also simulate two differnt type of modules with 1 inverter ?

Thanks,

Depending on the inverter you can use the multi mppt feature to model across different sub-arrays assigned to different orientations. This can be done to model different orientations, modules, etc.

Applying the probabilistic evaluation P90 to hourly, daily of even monthly values doesn't make sense.

P90 is an annual evaluation.

Please see our FAQ "What is the P50-P90 probability production ?".

PVsyst only allows mixing the orientation #1 and #2 on a same inverter input. This is a limitation.

Now you can define several sub-arrays, with different MPPT inputs, for different orientations.

The sub-array - i.e. inverter MPPT input - may only be defined in an homogeneous way (same module, same number of modules in series).
