How Much Do Solar Panels Cost in 2026?

The short answer: $2.58 per watt on average nationally, before any incentives. For a typical 12 kW system, that's roughly $30,500^[1].

But that number doesn't tell you much, does it? As a team that reviews hundreds of real solar quotes every month, we always tell homeowners: what you actually pay depends on your state, your roof, your equipment choices, and — this is the big one in 2026 — whether you buy the system or let someone else own it.

Because here's the thing: the 30% federal tax credit that made solar affordable for millions of homeowners? It's gone. Expired December 31, 2025. Since January 1st, our inbox has been flooded with panicked messages from readers asking if solar is dead. It's not, but it changes the math more than any price drop ever could.

Let's break it all down based on what we are seeing on the ground right now.

National averages: what people are actually paying

EnergySage, the largest solar marketplace in the US, tracks real quotes from real homeowners. Their latest data^[1]:

Notice something? The price per watt stays pretty flat. That's because most of the cost is labor, permits, and inverters — not the panels themselves. In fact, solar panels are only about 12% of the total installation cost^[1].

What you're actually paying for

When you get a solar quote, here's roughly where your money goes:

• Soft costs (~55%): Labor, permits, inspections, customer acquisition, installer overhead
• Inverter & electronics (~15%): Converts DC to AC, monitoring systems
• Racking & mounting (~10%): Hardware that holds panels to your roof
• Solar panels (~12%): The actual modules
• Misc (~8%): Electrical work, conduit, breakers

We constantly have to explain this to clients: this is why panel prices can drop 90% but your total installation cost only drops 30-40%. The panels are cheap. It's everything else that isn't.

Cost by state: where you live matters a lot

EnergySage's 2026 state-level data shows some wild variation^[1]:

Source: EnergySage Marketplace data, H2 2025. Costs are before any incentives.

When analyzing these numbers, three major anomalies jump out at our team:

• California has incredible savings ($132K over 25 years) because electricity is absurdly expensive there — not because solar is cheap.
• Texas is surprisingly affordable per watt ($2.36/W). Local installers we talk to attribute this to a competitive installer market driven by the state's deregulated electricity landscape.
• States with high $/W (like Illinois at $3.01) tend to have colder climates, stricter local permitting, and fewer installers competing on price.

What happened in 2026: the tax credit expiration

If you read our solar battery guide, you already know this. But it's worth covering again because it fundamentally changed solar economics.

The Section 25D Residential Clean Energy Credit — the one that gave you 30% back on your taxes — expired December 31, 2025^[2].

What that means in real dollars:

• 2025 (with 30% credit): $30,500 system → -$9,150 credit → $21,350 actual cost
• 2026 (no credit): $30,500 system → $0 credit → $30,500 actual cost

Same system. Nine thousand dollars more out of your pocket.

SEIA and Wood Mackenzie are forecasting an 18% drop in residential solar installations in 2026 as a result^[3]. In our recent interviews with regional solar companies, many admitted they are scrambling to restructure their sales strategies.

The financing workaround: PPAs and leases

There's still a way to get the benefit of a federal credit — just not directly.

Under a Power Purchase Agreement (PPA) or lease, a third-party company owns the solar system on your roof. They qualify for the Section 48E commercial tax credit (still active, 30-50% with bonus adders). The idea is that they pass those savings along to you through a lower electricity rate^[4].

Is it as good as owning the system and getting the credit yourself? Honestly, no. Historically, we have always championed ownership for maximum ROI. But given the reality of 2026, we've shifted our stance for certain homeowners. If you can't or don't want to pay $30,000 upfront, a PPA is currently the most viable option — and we're now recommending it more often than we used to.

Is solar still worth it in 2026?

Without the tax credit, the math is harder. But it's not hopeless. Let us give you our straight, unvarnished advice.

Yes, it's still worth it if:

• You live in a state with high electricity rates (CA, MA, CT, NY) — savings compound faster.
• Your roof gets good sun and faces south.
• You plan to stay in your home 10+ years.
• You go the PPA/lease route and your monthly payment is immediately less than your current electric bill.

Harder to justify if:

• Your electricity is cheap (under 12¢/kWh).
• You're planning to move within 7-8 years.
• Your roof needs replacement soon (that's an extra $8,000-$15,000 on top, and we always advise against installing panels on a roof with less than 10 years of life left).

Our insider tips to get the best price

Regardless of when you buy, these are the four rules we live by when vetting quotes for our community:

1. Get at least 3 quotes. Prices vary wildly between installers for the exact same equipment.
2. Compare price per watt, not total cost. A $25,000 10 kW system ($2.50/W) is a better deal than a $28,000 10 kW system ($2.80/W).
3. Don't oversize your system. A system that covers 80-90% of your usage is usually the sweet spot. We often see aggressive salespeople try to push 110% coverage, but selling power back at wholesale rates is a losing game.
4. Watch the add-ons. Some installers will try to sell you monitoring packages, extended warranties, or critter guards you don't need.

Bottom line

Solar panels cost about $2.58/W nationally in 2026. A typical 12 kW system runs about $30,500 before incentives. The 30% federal tax credit is gone, which makes the effective cost about $9,000 higher than it was last year.

But panel prices themselves keep falling. Installation is getting more efficient. And electricity rates aren't going down anytime soon.

If you're in a high-rate state with good sun, solar still makes financial sense — just with a longer payback period. If you're in a low-rate state, you might be better off waiting or going with a PPA.
