Entities (W) for each PV Tracker

[HansPeterMeier]

Is it possible to extend the entities with energy (W) like
PV1 Voltage * PV1 Current= PV1 W
with the power per area I can later calculate the amount of energy by integral

I have a ktl30-m3
PV1+PV2+PV7+PV8 (25,5kWp) are southeast
PV3+PV5 (15kWp) are northwest

Thanks for the great extension.
