The 2026 Pricing Reality
Two big forces are pulling in opposite directions right now. On one hand, the federal 30% Investment Tax Credit (ITC) expired December 31, 2025 — that's $6,000-$10,000 you used to get back from the IRS that's no longer available. On the other hand, solar equipment prices have fallen roughly 18% since 2023. N-type panels now hit 22-25% efficiency at lower module prices than ever before.
Net result: you're paying more out of pocket than you would have in 2024, but you're getting more power per dollar of equipment. The economics still work for most homeowners — they just require more careful analysis than they did when a 30% federal check was automatic.
Here's the complete cost picture.
Average Solar System Cost by Size (2026)
Most homes use a 6kW to 12kW system. Here's what fully installed systems cost in 2026 — before any state incentives:
| System Size | Installed Cost (2026) | Avg. Monthly Savings* | Panels Needed (@400W) |
|---|---|---|---|
| 6 kW | $17,000 – $21,000 | $95 – $145/mo | 15 panels |
| 8 kW | $22,000 – $27,000 | $125 – $195/mo | 20 panels |
| 10 kW | $26,000 – $32,000 | $155 – $240/mo | 25 panels |
| 12 kW | $30,000 – $38,000 | $190 – $290/mo | 30 panels |
* Monthly savings estimated at $0.15-$0.22/kWh average electricity rate with net metering. Actual savings vary by state and utility.
The most common residential system is 8-10kW, suitable for homes using 900-1,200 kWh/month (typical for a 3-4 bedroom house with central air). If you're not sure what size you need, our solar sizing calculator will tell you based on your electric bill.
Cost Per Watt: The Real Pricing Benchmark
The industry standard way to compare solar quotes is cost per watt (fully installed). Here's the 2026 breakdown:
| Cost Component | $/Watt | % of Total |
|---|---|---|
| Solar panels (equipment) | $0.65 – $0.95 | ~27% |
| Inverter(s) | $0.20 – $0.35 | ~10% |
| Racking & mounting hardware | $0.15 – $0.25 | ~7% |
| Labor & installation | $0.60 – $0.90 | ~27% |
| Permitting & inspection | $0.15 – $0.25 | ~7% |
| Installer overhead & margin | $0.55 – $0.85 | ~22% |
| Total installed cost | $2.50 – $3.50 | 100% |
National average: ~$2.95/watt. If you're getting quotes above $3.75/watt, you're overpaying — shop around. If a quote is under $2.20/watt, scrutinize the equipment specs; cheap inverters or off-brand panels with low efficiency can negate the savings.
The biggest cost variable isn't the panels — it's installer overhead and margin. Getting 3+ quotes routinely saves homeowners $3,000-$7,000 on the same system.

Calculate My System Size →What About the Federal Tax Credit?
The Investment Tax Credit (ITC) — which gave homeowners a 30% federal tax credit on solar installations — expired December 31, 2025 under the One Big Beautiful Bill Act. If you're installing solar in 2026, there is no federal tax credit.
That means on a $28,000 system, you're paying $28,000 — not $19,600. Your total cost went up by $8,400 compared to a 2024 installation. That's significant, and it's the main reason payback periods stretched from 4-6 years to 7-10 years.
However, the ITC expiration was partly anticipated by the market — panel prices continued dropping in 2025 and 2026, partially offsetting the impact. You're buying better equipment at lower prices.
State Incentives That Still Apply in 2026
The federal credit is gone, but many states have their own programs that meaningfully cut costs:
- New York: NY-Sun Megawatt Block incentive + 25% state tax credit (up to $5,000). Net effective cost reduction: $5,000-$7,000+ depending on system size.
- Massachusetts: SMART Program pays you per kWh generated (in addition to net metering). Plus state income tax credit up to $1,000.
- New Jersey: SREC-II program — earn certificates for every 1,000 kWh your system produces, tradeable for cash. Can generate $500-$1,500/year.
- California: SGIP battery storage rebate ($150-$400/kWh of storage). Solar itself has no direct state credit, but property tax exemption on solar-added home value applies statewide.
- Florida, Texas, Arizona: Property tax exemptions on solar-added home value (typically $15,000-$25,000 in assessed value exempted). No direct cash credit, but real savings over time.
- Illinois: Adjustable Block Program (ABP) — state pays per kWh for up to 15 years. Upfront value varies by market pricing.
The best resource is DSIRE (dsireusa.org) — the Database of State Incentives for Renewables & Efficiency. It's maintained by NC State and is the most accurate source for current programs.
Financing: What It Actually Costs Per Month
Most homeowners don't pay cash for solar. Here are the three main options and what they mean for your monthly numbers:
Solar Loan (Recommended for Most Homeowners)
You own the system outright. Interest rates in 2026 run 6.9%-9.5% for qualified buyers on a 12-20 year solar loan. On a $25,000 system at 7.5% over 15 years:
- Monthly loan payment: ~$232/month
- Monthly savings (8kW system, average rates): ~$150/month
- Net monthly cost: ~$82/month above your current electric bill
- After loan payoff (year 15): $150+/month in pure savings for another 10+ years
The key is: you're trading a variable, rising electric bill for a fixed loan payment. Once the loan is paid off, your electricity is essentially free.
Cash Purchase
Highest ROI option long-term. On a $26,000 system with $150/month in savings: 14-year payback at zero financing cost, then 11+ years of free electricity. The internal rate of return typically runs 6-9% — better than a CD, lower risk than equities.
Solar Lease / PPA (Generally Not Recommended)
You don't own the system — you pay a monthly fee for the electricity it generates. While this avoids upfront cost, you don't build equity, don't get incentives, and complicates home sale. Leases made sense before the ITC expired; in 2026, ownership options (loan or cash) are almost always the better financial choice.

Calculate My Savings →What Drives Your Price Up or Down
The system size table above shows ranges — here's what puts you at the high or low end:
Factors that lower your cost
- Simple roof layout: Single-plane, south-facing, no obstructions = minimal labor. Can cut $1,500-$3,000 vs. complex multi-pitch roofs.
- Ground mount (if you have land): Easier installation, optimal angle — often 10-15% cheaper per watt than a challenging rooftop job.
- Competitive local market: States with many installers (CA, TX, FL, AZ) see more competition, lower quotes.
- Smaller system: Economies of scale work in reverse at the small end — a 6kW system costs more per watt than a 10kW system from the same installer.
Factors that raise your cost
- Battery storage: Adding a home battery (Tesla Powerwall, Enphase, etc.) adds $8,000-$15,000 to the system cost. Worthwhile if your utility has unreliable power or unfavorable net metering; otherwise optional.
- Roof work needed: If your roof needs replacement within 10 years, add it before solar — removing and reinstalling panels costs $3,000-$5,000 extra.
- Complex roof or shading: Dormers, chimneys, trees = extra labor and likely microinverters (more expensive than string inverters but required for partial shading).
- Electrical panel upgrade: Older homes often need a main panel upgrade ($2,000-$4,000) to handle solar output. Your installer will flag this in the site assessment.
Price Trends: What's Coming
Panel prices have fallen steadily for two decades, and that trend continues. Here's the rough trajectory:
- 2023: ~$3.60/watt installed (national average)
- 2024: ~$3.20/watt (ITC made net cost ~$2.25/watt)
- 2025: ~$3.05/watt (last year of ITC; net cost ~$2.14/watt)
- 2026: ~$2.95/watt (no ITC; full out-of-pocket)
- 2027-2028 (projected): ~$2.60-$2.80/watt as perovskite and tandem cell technology hits commercial scale
If you're on the fence: waiting 18-24 months could save 8-12% on equipment costs. But electricity prices are rising ~3.5% annually, and every month you delay is another month of full electricity bills. The optimal time to go solar is usually "now, if your numbers work." Use our calculator to check your specific payback period.
The Bottom Line on Solar Costs in 2026
A fully installed residential solar system costs $18,000-$38,000 depending on size, at roughly $2.50-$3.50/watt installed. No federal tax credit applies — the ITC expired December 31, 2025. State incentives still exist in many markets and can cut costs by $1,000-$7,000+.
The honest math: for homeowners paying above $130/month in electricity, in states with decent net metering, solar still pencils out — payback in 7-10 years, then 15+ years of free electricity. For homeowners in low-rate states without state incentives, the numbers are tighter and require careful analysis.
Run your specific numbers. The difference between "solar makes sense" and "solar doesn't make sense" is entirely about your electricity rate, your roof, and your state — not national averages.
FAQ
How much do solar panels cost in 2026?
A fully installed residential solar system costs $17,000-$38,000 before incentives, depending on system size. Most homes use 8-10kW systems, running $22,000-$32,000 installed. Cost per watt is $2.50-$3.50, down about 18% from 2023 prices.
How much does solar cost per watt in 2026?
