Currently building a new house scheduled to be done in June/July timeframe. 2265 sq ft, two stories, rear of house faces almost directly south. South Carolina has a rather impressive 25% state tax credit on top of the 30% federal tax credit, so looking to install 8 kW solar panels + 1 Powerwall. Trying to guesstimate energy usage based on my current house, but I will have all electric heating and cooling at my new house vs natural gas heat at my current house. So I am expecting a hefty increase in the electric bill. I may up to 8.8 or 9.6 kW solar (22 & 24 panels vs 20 panels at 8 kW).
Anyone who has done this already have any tips, tricks, or advice? Are there still long wait times or did Tesla catch up on inventory now?
Is it worth getting 2 Powerwall's or is that overkill? I have read 1 Powerwall really can't support a central HVAC when the grid is down, but solar panels + 1 Powerwall can. You would need 2 Powerwall's to support central HVAC if the grid is down, I think. It's a new house so it'll have a 15 SEER unit which is pretty energy efficient. I have also heard they may move to LFP chemistry for Powerwall soon.
