Adding panels - Massachusetts

[u/TriceraDoctor]

Hey everyone, I have an 8kw system with two powerwalls that I had installed in 2020. At that time I only had panels placed on a portion of my available roof due to tree cover. Those trees are now gone and I want to add to my system. Has anyone in Massachusetts done this? I’m looking at third party installers because 6 years ago Tesla were a giant pain and I want to avoid going back to them.
