The price leader
Tesla installs at $2.20–$2.60/W — consistently 10–20% below national competitors. A 10 kW system that costs $28,000 with Sunrun runs about $24,000–$25,000 with Tesla. The fully online ordering (design, price, schedule in ~20 minutes) cuts overhead and sales pressure.
Powerwall 3 is the differentiator
Tesla's Powerwall 3 combines battery + hybrid inverter in one unit, and the ecosystem integrates panels, battery, and the Tesla app. For NEM 3.0 states where self-consumption matters, it is a strong integrated package.
The trade-offs
Tesla is self-directed: no hand-holding, subcontracted install crews in some markets, and service can be slow. Workmanship warranty is 10 years; panels carry a 25-year performance warranty. Best for buyers who know what they want and want the lowest price.
