How Much Do Solar Panels Cost in 2026? (Real Numbers)

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.
