If you have solar panels you mostly use a, so called, string inverter. All the cells of the panels are connected in series and the DC power is converted in one single inverter to AC. The disadvantage of such a system is that, if one panel, e.g. because of shadow, produces less power then the others, the whole system switches back to that lower level. You can solve this by means of optimizers.
Another solution is to use micro-inverters. Each single solar panel gets its own inverter and the DC power is directly converted on the roof to AC.
You don't have a (larger) inverter in your house.
This system has several advantages, but the disadvantage is that it is more expensive if you have a large number of solar panels.
One of the advantages is that you can read the individual power production of each panel.
As recently the functionality of the Enphase Envoy-S has been extended and now also support the Envoy-S metered, I suggest that the software for Enphase S is extended once more so that we are able to read the power production of each individual solar panel.

In this case it will give you all the results for the individual panels.

I have made it this way with Node Red and it works fine for about 3 months now.
Would be a good idea to have this natively implemented in the Enphase "hardware".
I'm open for discussions and other suggestions.
