I have 2 inverters in parallell. To Slave is connecyed 9 panels south carport roof and 10 on west roof, to the 2 connections.

To Master is connected 17 panels on south roof and 10 on east roof.

That makes a big unbalance on south between inverters.

I have now added 3 of the south roof to the 9 on carport. So south roof now has 14 panels and carport have 12 panels.

Now to my question, is it very negative to add panels that are "far away", have different inclination and different energy?

I add 2 pictures that will show situation before and after.

I don't think the electrons care 😋

The distance between parts of a string is not a problem if the cable can handle the current without excessive volt drop.

However for parts with different orientation, the poorest producing part will dictate the whole string.

Current is the same through all panels in series. Just like a garden hose pipe if you pinch any part the flow of water drops for the entire hose.
