How Much Do Solar Panels Cost in 2026? (Real Numbers)
By SunSavvy Team · Updated July 20, 2026
Short answer: A typical US home pays about $21,000–$27,000 for a 7–9 kW solar system before incentives, or roughly $14,700–$18,900 after the 30% federal tax credit. The fairest way to compare quotes is cost per watt, which usually lands between $2.50 and $3.50.
The short answer: most US homeowners pay roughly $2.50–$3.50 per watt for an installed solar system before incentives. For a typical 8 kW system, that’s about $20,000–$28,000 gross, or noticeably less after any tax credits and incentives you qualify for.
But averages hide a lot. Here’s what actually drives the number.
Cost by system size
At a mid-range $3.00 per watt, gross cost scales roughly like this:
| System size | Gross cost (before incentives) | Rough home fit |
|---|---|---|
| 5 kW | ~$15,000 | Small home / low usage |
| 8 kW | ~$24,000 | Typical US home |
| 10 kW | ~$30,000 | Large home / high usage |
| 12 kW | ~$36,000 | Very high usage / EV |

What’s included in the price
A quoted price almost always bundles:
- Panels (the cheapest part these days).
- Inverter(s) — string inverter or microinverters.
- Racking and mounting hardware.
- Labor and installation.
- Permitting, inspection and utility interconnection.
- Installer overhead and warranty.
“Soft costs” — permitting, sales, labor, overhead — often make up half or more of the total. That’s why the same panels can cost very different amounts depending on who installs them.
What makes your price higher or lower
- Roof complexity: steep, multi-facet or shaded roofs cost more.
- Panel and inverter tier: premium equipment adds cost but can add output.
- Battery storage: adds roughly $10,000–$18,000 for a home battery.
- Your state and installer market: competitive markets are cheaper.
Incentives change the real cost
Federal, state and utility incentives can cut the sticker price substantially. Incentive rules change frequently, so treat any percentage you read (including in our calculators) as a starting assumption and confirm current eligibility — see our solar tax credit guide and a licensed tax professional.
Is it worth it?
Cost is only half the equation — what matters is payback and lifetime savings versus your rising utility bill. We walk through that in Is solar worth it?, or you can jump straight to the Solar Payback Calculator.

Frequently asked questions
- How much does a solar system cost in 2026?
- Most US residential installs run $2.50–$3.50 per watt before incentives. A typical 8 kW system is therefore around $20,000–$28,000 gross, or roughly $14,000–$19,600 after the 30% federal tax credit.
- Is solar cheaper than it used to be?
- Dramatically. Panel prices have fallen by around 90% since 2010. Hardware is now a minority of the total — labour, permitting, sales and overhead make up most of an install, which is why prices have flattened in recent years.
- Why do solar quotes vary so much?
- Different system sizes, equipment tiers, roof complexity, local labour rates, and very different sales and financing markups. A dealer fee on a financed quote alone can add 15–30% to the price.
- What is not included in a solar quote?
- Commonly a main electrical panel upgrade ($2,000–$4,000), roof repair or replacement, tree removal, ground-mount trenching, and battery storage. Ask which of these apply before signing.
