Is Solar Still Worth It Without the Federal Tax Credit? (2026 Analysis)

The federal Investment Tax Credit (ITC) is gone. On January 1, 2026, the 30% tax credit that had been the centerpiece of residential solar economics was eliminated. Without it, a $24,500 system now costs $24,500 — not $17,150.

Does solar still make financial sense? The short answer is yes, in most cases — but the math has changed. Here's our full analysis.

The New Solar Math: 2025 vs 2026

Here's how the elimination of the ITC affects the bottom line:

2025 (with 30% ITC): 7kW system cost = $17,150 after credit. Annual savings (at $0.14/kWh) = $1,470. Payback period = 7–9 years. 25-year net savings = $23,000–$30,000.
2026 (without ITC): 7kW system cost = $24,500. Annual savings (at $0.14/kWh) = $1,470. Payback period = 10–12 years. 25-year net savings = $14,000–$20,000.

Without the ITC, the payback period is roughly 3 years longer, and total lifetime savings are reduced by about 35%. But the system is still cash-flow positive over its 25+ year lifespan.

The Electricity Rate Escalation Factor

The key factor that keeps solar viable in 2026 is electricity rate inflation. US electricity rates have risen 3–5% annually over the past decade, and the trend shows no sign of slowing.

At 4% annual rate escalation, a system that saves you $1,470 in year one will save you $2,180 in year ten and $3,920 in year 25. Compounding utility rate increases dramatically improve solar's long-term ROI — even without the ITC.

State Incentives Can Bridge the Gap

While the federal ITC is gone, many states still offer meaningful incentives that can reduce your net cost by 10–30%:

New York: NY-Sun rebate of $0.20/W, up to $5,000
Massachusetts: $1,000 state tax credit + SMART incentive payments
New Jersey: Active SREC market generating $150–250/MWh
Colorado: Property tax exemption for solar installations
Maryland: State tax credit up to $1,000
Illinois: Adjustable Block Program with significant upfront incentives

Payback Period: With ITC vs Without ITC

States with strong incentives (NY, MA, NJ, IL, CO): 7–9 years (vs 5–7 with ITC)
States with moderate incentives (CA, MD, OR, MN): 8–11 years (vs 6–8 with ITC)
States with weak or no incentives (most of the South and Midwest): 10–14 years (vs 7–10 with ITC)

25-Year ROI Projections

Even without the ITC, the 25-year ROI for solar remains positive in most of the country due to electricity rate escalation. Here are typical 25-year net savings (assuming 4% annual rate escalation):

California (high rates): $35,000–$55,000 net savings
New York/MA/NJ (high rates, strong incentives): $25,000–$45,000 net savings
Texas/Florida (moderate rates): $12,000–$22,000 net savings
Midwest/South (low rates, weak incentives): $5,000–$12,000 net savings

In every category, solar still generates positive long-term returns. The question isn't whether solar works financially — it's whether you'll be in your home long enough to capture the savings.

When Solar Isn't Worth It Without the ITC

Solar may not be worthwhile if: you plan to move within 7–10 years, you're in a state with very low electricity rates (below $0.10/kWh) and no incentives, your roof needs replacement within 10 years, or you can only finance at high interest rates (above 8–10% APR).
