Peak power of day Forecast.Solar

I have setup Forecast.Solar with two panel setups.
How do i setup sensor, so that it will give me peak power today (or tomorrow), not time, just power?
I can see that figure in 12h and 24h graph, but dont know how to extract that to sensor.

E. I would use this data to tweak evcc actions, specially on winter times, to change enable/disable thresholds.

EE. Found statistics integration and got right values.
