My Y is at 31k in Austin. Summer efficiency runs lower than your numbers — HVAC load in Texas heat is real, I'm seeing 255–270 Wh/mile in July versus 210 in March. The data logging habit is exactly right, and your service observation is also exactly right. Two weeks for an appointment to look at a door handle is not a support ratio that matches the vehicle price.

The insurance number is what every TCO calculator buries or omits. My Y LR came in $91/month higher than my previous F-150 after accounting for replacement cost. Three years of fuel savings nearly canceled by three years of insurance delta. The EV is still better on cost — but the honest math is a lot less dramatic than most forum posts make it look.

Texas has NEVI funds allocated but deployment has been painfully slow. Drove Austin to Denver in April and the Wichita Falls to Amarillo stretch was genuinely sparse — I ended up doing a 90-minute hotel Level 2 charge. The NEVI map shows stations planned on that corridor but nothing is open yet. Happy to share the full trip report if anyone's planning the same route.

Texas has no state storage incentive, so the federal 30% standalone credit is the whole story for me. Does the credit apply to individual cells purchased from importers, or only to complete packaged battery systems? I want to confirm the BOM I hand my CPA actually qualifies before I commit to the build.

Just contracted a 10kW rooftop install last month and my installer quoted $850/kWh for a Powerwall 3. At $42/cell for 280Ah LFP, a 20kWh DIY pack looks very compelling. Main question is inverter integration — going with SolarEdge and I'm not sure how a DIY battery plays with it versus a purpose-built AC-coupled unit like the SolarEdge Home Battery.

Year two on an R1T. Hardware build quality has genuinely improved from the early batches — anyone who touched a 2022 delivery can feel the difference. The weak point is software. Two of the last four OTAs introduced something that needed a follow-up patch. The truck is excellent. The software release process is still a startup's, not a truck company's.
