You’re standing in the aisle of a home improvement store or scrolling through a specialized wholesale site, looking at a single, sleek rectangle of glass and silicon. You want to know the price. Simple, right? Well, sort of.
The thing is, asking how much does one solar panel cost is a lot like asking what a single car tire costs. You can buy one for fifty bucks to put on a trailer, or you can spend five hundred on a high-performance Michelin for a Porsche. In the solar world, that "sticker price" for one panel usually floats between $200 and $450 for a standard residential module.
But here’s the kicker: nobody really buys just one panel to power a house. If you're looking at a full rooftop installation, that single panel price is basically a ghost. It gets swallowed up by labor, permits, inverters, and the guy who has to climb onto your roof with a heavy harness.
The Raw Hardware: What’s on the Label?
If you’re a DIYer building a van setup or a small shed, you’re looking at the "uninstalled" price. Honestly, this is where you see the most variety.

For a standard 400-watt monocrystalline panel—which is pretty much the gold standard in 2026—you’re likely shelling out about $0.70 to $1.20 per watt. Do the math, and that’s roughly $280 to $480 for that one piece of hardware.
Now, if you go for the older polycrystalline stuff (the blue-tinted ones that look a bit like glittery static), the price drops. You might find those for as low as $0.60 per watt. They’re cheaper, sure, but they’re also less efficient. You’d need more of them to get the same juice, which eventually eats up more of your roof space.
Why some panels cost way more
- Bifacial technology: These panels catch light on both sides. They’re great for ground mounts where light bounces off the grass or snow, but they’ll run you about 15% more.
- Efficiency ratings: A panel that hits 22% efficiency is going to be pricier than one that hits 17%. You're paying for the engineering that squeezes more power out of the same square inch.
- Brand name: Going with a Tier 1 manufacturer like Maxeon or Hanwha Q Cells usually means a better warranty, but you'll pay a premium for that peace of mind.
The "Installed" Reality
Most people aren't buying panels at a retail shop. They’re buying a "system." When you look at a professional quote, that single solar panel doesn't cost $300 anymore. It costs more like **$1,000 to $1,200**.
Wait, what?
Yeah, it sounds like a rip-off until you break down the "soft costs." According to recent data from EnergySage and NREL, the actual solar module—the physical panel—only accounts for about 12% to 15% of your total bill.
The rest of the money goes to:
- The Inverter: These are the brains. They turn the DC power from the sun into AC power for your toaster.
- Mounting Hardware: The rails and bolts that keep the panels from flying off during a windstorm.
- Labor: This isn't just the guys on the roof; it's the engineers who designed the layout and the electricians who handled the high-voltage wiring.
- Permitting and Interconnection: Your local utility and city council want their cut and their paperwork. This can easily add $1,000+ to a project.
How much does one solar panel cost across the US?
Location matters. A lot.
If you're in Arizona, you might see lower prices because the market is saturated and installers are fighting for your business. In a place like South Dakota or Alaska, things get pricier because the supply chains are thinner.
In 2026, the average cost per watt installed is hovering around $2.50 to $3.30. For a typical 10 kW system (which is about 25 panels), you're looking at a gross price of roughly $25,000 to $33,000 before any incentives.
If you divide that by the 25 panels, you get a "per panel" installed cost of $1,000 to $1,320.
A quick look at state-by-state averages (Before Credits)
- Texas: ~ $2.64 per watt
- California: ~ $3.06 per watt
- Florida: ~ $2.53 per watt
- New York: ~ $3.30 per watt
It's weirdly inconsistent. You'd think sunny states would always be cheapest, but labor costs and local regulations often play a bigger role than the actual sunshine.

The 2026 Incentive Landscape
Don't panic at those big numbers. As of right now, the Federal Investment Tax Credit (ITC) is still a massive player. For residential systems installed this year, you can usually claim a credit for 30% of the total cost.
If your "per panel" installed cost was $1,200, the tax credit effectively brings it down to **$840**.
But there’s a catch for 2026. There’s been a lot of talk about the Foreign Entities of Concern (FEOC) rules. These are new regulations that might limit tax credits if the panels contain too many components from certain countries, specifically China. This has some people worried that prices might tick up as installers scramble for "domestic content" panels that meet the new requirements for extra bonuses.
Is it worth just buying one?
Honestly? Probably not for your home.
The "truck roll" cost is real. An installation company isn't going to send a crew, a truck, and an electrician to your house to install one panel for $1,200. They’d lose money.
If you're just looking to charge a phone while camping, buy a portable 100W folding panel for $150. If you want to offset your $200 monthly electric bill, you’re looking at a commitment.

What to check before you buy
- Roof Age: If your roof needs replacing in three years, don't put solar on it now. You'll pay thousands just to take them off and put them back on later.
- Your "Why": Are you doing this to save money or for backup power? If it's for backup, a single panel won't help without a battery, which can add another $8,000 to $15,000 to the bill.
- Shading: One tree can kill the production of an entire string of panels if you don't use microinverters.
Actionable Steps for Your Solar Journey
Don't get hung up on the price of a single panel. Instead, focus on the Levelized Cost of Energy (LCOE). This is basically how much you're paying for electricity over the 25-year life of the system compared to what the utility company charges.
- Check your last 12 months of electric bills. Find your average kWh usage. This tells you how many panels you actually need, not just what the salesperson wants to sell you.
- Get at least three quotes. Use a platform like EnergySage or just call local installers. Prices vary wildly even within the same zip code.
- Ask about the "Adders." If your electrical panel is 40 years old, you might need a "Main Panel Upgrade" (MPU), which can add $2,000 to your total before a single solar panel even touches your roof.
- Verify the warranty. Make sure it covers "labor" for replacements, not just the hardware. Replacing a "free" panel under warranty can still cost you $500 in labor if you aren't careful.
By looking at the total system value rather than just the price of a single silicon wafer, you'll get a much clearer picture of whether the investment actually makes sense for your wallet.
