Solar economics in one paragraph
A typical 8 kW system in 2026 costs $20,000–$28,000 gross. After the 30% federal ITC, net is $14,000–$19,600. With average USA electricity at $0.17/kWh and rising 3% annually, payback runs 7–11 years and lifetime savings clear $35,000–$55,000.
Best solar states in 2026 (payback in years)
- California: 5–7 (rate escalation + TOU)
- Massachusetts: 6–8 (SMART incentive)
- New York: 6–8 (NY-Sun rebate)
- New Jersey: 7–9 (SREC-II)
- Texas: 8–11 (net billing varies by utility)
- Florida: 8–10 (net metering under threat)
Battery storage: still optional in most states
Add a battery only if (a) your utility has TOU with a 3x+ peak differential, (b) you have frequent outages, or (c) net metering was replaced by net billing. Otherwise batteries add $12–$18K and stretch payback by 4–6 years.
