Now that the price dropped 30%+ it's economical for me to add more panels. I would keep the same inverter (mine doesn't clip), gets to about 5.5kw max on 7.1kw inverter. It's my understanding that oversizing the system is the most economical route to expansion. What's the best way to go about this? I feel like I could even DIY it since all the conduit is in place. Just add some more next to existing panels? Or is this something tesla would agree to do for a price.
