How much do solar panels cost?
The honest, complete breakdown — price per watt, cost by system size, what's actually in the price, and how financing and incentives change your real number in 2026.
Panels only. The 30% federal tax credit expired Dec 2025, so 2026 quotes no longer include it.
Educational estimate. Final price depends on roof, equipment & installer.
In the U.S., a solar panel system costs about $2.50–$3.50 per watt installed — roughly $20,000–$38,000 before incentives for a typical 8–11 kW system. The big 2026 change: the 30% federal tax credit expired at the end of 2025, so quotes no longer include it. Equipment is less than half the price; the rest is labor, permits, and soft costs — which is why the same system can be $2.75/W from a lean local shop and over $4/W from a national brand. Thinking about a battery too? See our dedicated solar battery cost guide.
Solar cost per watt, explained
Solar is priced in dollars per watt ($/W) — the single most useful number for comparing quotes. You take the system's total price and divide by its size in watts. A 9 kW (9,000-watt) system quoted at $27,000 is $3.00/W. This lets you compare a big system to a small one on equal footing, and it is how every installer and analyst talks about price.
In 2026, expect these ranges for a panel system:
Where you land in that range depends mostly on your installer's business model. Value-focused local shops sit near the bottom; national brands and premium full-service installers charge more for financing, brand-name equipment, and convenience. Same sun, same roof — the price gap is real, which is why getting multiple quotes matters.
Why "per watt" beats "total price"
A $30,000 system isn't expensive if it's a big 12 kW array ($2.50/W) — and a $20,000 system isn't cheap if it's a small 5 kW one ($4.00/W). Always convert quotes to $/W before you compare them.
Solar panel cost by system size
Most homes need somewhere between a 6 kW and 12 kW system, depending on electricity usage. Here's what each typically costs installed, before incentives, at representative 2026 pricing:
| System size | Installed cost* | Annual output | Best for |
|---|---|---|---|
| 6 kW | $15,000–$21,000 | ~8,700 kWh | Smaller homes, lower bills |
| 8 kW | $20,000–$28,000 | ~11,600 kWh | Average usage |
| 9 kW | $22,500–$31,500 | ~13,000 kWh | Most popular size |
| 11 kW | $27,500–$38,500 | ~16,000 kWh | Larger / all-electric homes |
| 12 kW | $30,000–$42,000 | ~17,400 kWh | High usage, EV charging |
*Panels only, before incentives, at $2.50–$3.50/W. Output assumes ~1,450 kWh per kW per year, typical for U.S. sun.
The right size isn't the biggest one you can fit — it's the one that covers your actual usage without overbuilding. An installer sizes it from 12 months of your electric bills, which is why uploading a recent bill produces a far more accurate quote than a rough online guess.
What's actually included in the price
One of the most common surprises for homeowners: the panels are less than half the cost. A solar price bundles hardware, labor, and a stack of "soft costs." Here's the full breakdown of where your money goes:
Panels (~25–30%)
The modules themselves. Tier-1 brands (Qcells, REC, Panasonic) cost more than budget panels but last longer.
Inverter (~10–15%)
String, microinverters, or optimizers. Micros and optimizers cost more but handle shade better.
Racking & mounting (~10%)
The rails and hardware that attach panels to your roof, plus flashing to keep penetrations watertight.
Electrical & wiring (~10%)
Conduit, wiring, a possible main-panel upgrade, and safety disconnects.
Labor (~15–20%)
Design, the actual installation crew, and electricians. Local in-house crews often cost less than subcontracted ones.
Soft costs (~15–20%)
Permits, inspection, the utility interconnection application, sales, overhead, and warranty backing.
Soft costs are why quotes vary so much
Two installers can buy the same panels for nearly the same price. The difference in your quote is mostly labor and soft costs — sales commissions, overhead, and marketing. That's exactly why the same system can be $2.75/W from a lean local shop and $4.45/W from a national brand.
What drives your price up or down
Two homes on the same street can get different quotes. These are the factors that move your number:
- System size. Bigger systems cost more in total but often less per watt, thanks to fixed costs spread across more panels.
- Panel tier. Premium high-efficiency panels (SunPower/Maxeon, Panasonic) cost more than standard Tier-1 modules — worth it on small roofs where space is tight.
- Inverter type. Microinverters and optimizers add cost but recover production on shaded or complex roofs.
- Roof complexity. Steep pitches, multiple facets, tile or metal roofing, and tricky access raise labor.
- Electrical upgrades. An older main panel may need an upgrade to handle solar — a common few-thousand-dollar line item.
- Battery & backup. Storage is the single biggest add-on — covered fully in our battery cost guide.
- Installer model. Lean local shops vs. national brands — often the largest swing of all.
Don't forget the roof underneath
If your roof is near the end of its life, replacing it before (or with) solar avoids a costly panel removal-and-reinstall later. Factor roof condition into your real cost — see our roof health & solar guide.
How people pay for solar
The way you pay changes both your upfront cost and your long-term savings. There are three main paths:
| Option | Upfront | You own it? | Best for |
|---|---|---|---|
| Cash purchase | Full price | Yes | Lowest lifetime cost, fastest payback |
| Solar loan | $0–low down | Yes | Owning with monthly payments |
| Lease / PPA | $0 down | No (provider owns) | No upfront cost, less hassle |
- Cash gives the lowest total cost and the fastest payback — no interest, all the savings are yours.
- Loans let you own the system with little or nothing down; interest adds to lifetime cost, but you keep all production value and any incentives you qualify for.
- Lease / PPA means a third-party provider owns the system and you pay $0 down for the power. With the federal tax credit gone for cash buyers, third-party-owned models can still capture commercial incentives — though you don't own the system or directly claim its value.
Incentives: what changed in 2026
This is the part of solar cost that shifted most. The headline: the 30% federal Residential Clean Energy Credit expired on December 31, 2025. Systems installed in 2026 no longer qualify, which raised the real net cost for cash and loan buyers.
But homeowners still have meaningful incentives:
Local utility rebates
Some utilities and states offer rebates — often for solar-plus-battery systems installed by a participating contractor. Amounts and eligibility vary by area — details in our battery cost guide.
Property-tax exemption
Many states exempt the home-value added by solar from your property taxes — the resale bump doesn't raise your tax bill.
Net metering
Favorable net metering credits your exported power — an ongoing incentive that, over time, can be worth more than any one rebate. Rules vary by state and utility.
Local & co-op rebates
Some cities, co-ops, and states offer additional rebates that stack on local utility programs. A local installer will know which apply.
The bottom line on the federal credit
If you signed and installed before the end of 2025, you may still claim the 30% credit on your 2025 taxes — confirm with a tax professional. For 2026 installs, budget as if it doesn't exist, because it doesn't.
Cost vs. long-term savings
The sticker price is only half the story — solar is a long-term asset that produces value for 25-plus years. A typical system offsets $1,500–$2,400 a year in electricity costs, and that figure rises as utility rates climb. Over the system's life, lifetime savings commonly land in the $25,000–$55,000 range after payback.
Two levers move payback the most: securing favorable net metering and capturing any local storage rebates with a battery. And because electricity prices keep rising — driven by AI, data centers, and grid strain — every rate increase makes your own production more valuable and shortens payback further. Our is-solar-worth-it guide runs the full payback math.
How to read a solar quote
When the quotes come in, compare them on equal terms. Here's what to check on every proposal:
- Convert to $/W. Divide total price by system watts. This is the only fair way to compare quotes of different sizes.
- Check the equipment. Panel brand and wattage, and inverter type — not just the headline price.
- Confirm what's included. Permits, interconnection, a main-panel upgrade if needed, and monitoring should be in the price, not surprise add-ons.
- Read the warranties. Separate equipment, inverter, and workmanship warranties — and how long the installer itself stands behind the work.
- Verify the production estimate. Annual kWh should match your usage and roof; a wildly high estimate inflates the apparent savings.
- Match the financing. Compare cash-to-cash or loan-to-loan, and watch for dealer fees baked into financed quotes.
