Makes sense, that’s like 80% more solar capacity and you’re probably paying the Tesla markup on the batteries. You’d also need a larger inverter, as 2 powerwalls inline would give 10kW output (5kW each). My battery and inverter are Solaredge, and the inverter is only 7.2kW.
Sounds like the price was relatively in line with mine, just different parts and larger scale.
Just finished installing a 11kw system with 2 Powerwalls in MA and it was closer to $70k. Rebates, tax credit, etc. will help a lot though.
