Average Solar Panel Cost in 2026
In 2026, the average cost of a residential solar panel system in the United States ranges from $2.50 to $3.50 per watt, depending on your location, the equipment you choose, and the complexity of your installation. For a typical American home that needs a 7kW (7,000-watt) system, that translates to a total cost of $17,500 to $24,500 before incentives.
The good news? Solar costs have dropped by over 70% since 2010, and the 30% federal solar Investment Tax Credit (ITC) remains in effect through 2032. After applying just the federal credit, your net cost for a 7kW system drops to approximately $12,250 to $17,150.
Many states also offer additional incentives — like property tax exemptions, sales tax exemptions, and local rebates — that can bring your cost down even further.
What's Included in the Cost?
When you see a “per watt” price quote for solar panels, it typically includes everything needed for a complete installation:
Solar Panels
25–30%The photovoltaic modules that convert sunlight to electricity
Inverter(s)
10–15%Converts DC power from panels to AC power for your home
Mounting & Racking
5–10%Hardware that secures panels to your roof
Labor & Installation
15–20%Licensed electricians and installers
Permitting & Inspection
5–10%Local permits, utility interconnection, inspection fees
Design & Engineering
5–10%System design, structural analysis, electrical plans
Solar Panel Costs by State
Solar costs vary significantly by state due to differences in labor costs, permitting requirements, local incentives, and market competition. Here's a breakdown for the top solar states:
| State | Cost/Watt | 7kW System | After 30% ITC |
|---|---|---|---|
| California | $2.80–$3.20 | $19,600–$22,400 | $13,700–$15,700 |
| Texas | $2.50–$2.90 | $20,000–$23,200 | $14,000–$16,200 |
| Florida | $2.45–$2.85 | $19,600–$22,800 | $13,700–$15,960 |
| Arizona | $2.40–$2.80 | $16,800–$19,600 | $10,760–$12,720 |
What Affects Your Solar Panel Cost?
System Size
Larger systems cost more overall but less per watt. Your energy usage determines the ideal size — most homes need 5–10kW.
Panel Brand & Efficiency
Premium panels (like SunPower or REC) cost more per watt but produce more energy per square foot, which matters if you have limited roof space.
Roof Type & Condition
Standard asphalt shingle roofs are the cheapest to install on. Tile, metal, or flat roofs may add $500–$2,000 in extra costs.
Battery Storage
Adding a battery (like the Tesla Powerwall) adds $8,000–$15,000 to your total cost, but provides backup power and can maximize self-consumption under net metering programs.
Local Labor & Permitting
Labor costs and permitting fees vary significantly by city and state. Urban areas with high competition may offer lower prices.
Installer Choice
Getting multiple quotes is essential — prices can vary 20–30% between installers for the same system. Voltmatch helps you compare quotes from vetted installers for free.
Solar Financing Options
You don't need to pay for solar panels all at once. Here are the most common financing options in 2026:
Cash Purchase
Pros: Best long-term ROI, own the system outright
Cons: Highest upfront cost
Solar Loan
Pros: No upfront cost, you own the system, eligible for tax credit
Cons: Interest adds to total cost
Solar Lease
Pros: No upfront cost, predictable monthly payments
Cons: You don't own the system or get the tax credit
PPA (Power Purchase Agreement)
Pros: Pay only for electricity produced, no maintenance
Cons: No ownership, savings may be lower than purchase
Are Solar Panels Worth the Cost in 2026?
