Need help with smart meter monitoring

Hardware
1

Hello to all,

I am currently doing a thesis on the monitoring of a smart meter. I used this tutorial to create the port p1 reader. : Studio Noorderlicht Building an ESP8266 DSMR5 reader for Home Assistant

Here is what my entities look like: https://raw.githubusercontent.com/daniel-jong/esp8266_p1meter/master/assets/p1_sensors.yaml

However I don’t understand how to get the values from the solar panels. Here is what my energy menu looks like.

These entities are already the ones I put for the power grid tab so I don’t know how to do it.

I looked several times at the OBIS codes but I can’t find anything that corresponds to the solar panels, is there a trick to do?

Thank you in advance for your help.
