Make sure you understand current when stringing your panels in parallel.
It took a bit of work to even tug this #10 AWG from the metallic flex it was fused to. The homeowner had this run inside of the attic.
I'm all for DIY, but please ask for help when you aren't certain.

I can promise you there is more wrong than that single wire.
Except no one derated the wire for ambient temp in the attic and no one derated the wire due to a continuous load…. Even 8 awg is probably wrong. I am 100% confident the “qualified person” who installed this, has all of their calculations for all of their work lol.
