How Much Do Solar Panels Really Cost After the Latest Incentive Changes? (2026)

Last updated: October 24, 2026

In the US, a typical 12 kW home solar system costs about $31,135 before incentives, or roughly $2.60 per watt (EnergySage marketplace data, October 2026). The 30% federal homeowner credit ended on December 31, 2025, so that sticker price is now close to what most buyers actually pay. Gulf and UK costs depend on local rules, covered below.

What changed, and when

Most “solar cost” articles still subtract 30% from the price. That is outdated for the US. Here is what has changed, region by region.

The IRS is explicit on the US credit: if installation is completed after December 31, 2025, the expense counts as made after that date, even if you paid earlier. Paying a deposit in 2025 does not save the credit.

How much do solar panels cost in the US in 2026?

The simplest way to compare quotes is price per watt:

System cost = system size in watts × price per watt

EnergySage’s marketplace data (quotes from competing installers, updated October 2026) shows these averages before any incentives:

The overall average for a typical 12 kW system is $31,135, with a range of about $27,500 to $33,900 across quotes. Larger systems cost less per watt because fixed costs (design, permits, sales) are spread over more panels.

The panels themselves are a small slice. EnergySage’s breakdown of a $31,135 system puts panels at about 12%, inverters at about 10%, and sales and marketing at about 18%. Permits and grid connection take about 8%. That is why two quotes with the same panel brand can differ by thousands of dollars.

Why online prices do not match your quote

Two numbers circulate in 2026 and both are correct, for different things:

• About $2.58–$2.60 per watt: the average quote on EnergySage, where installers compete for your project.
• About $3.50 per watt: the 2024 median price for cash purchases in Lawrence Berkeley National Laboratory’s October 2025 report, which covers completed projects across the wider market.

That gap of roughly $1 per watt is the price of shopping by comparison versus accepting the first offer. On a 10 kW system, $1 per watt is $10,000.

Financing also changes the contract price. Loan-financed systems often carry dealer fees inside the total, so the same roof and equipment can show a higher price than a cash quote. Always ask for the cash price and the financed price side by side.

Your real cost: before and after the credit

Here is a worked example for a 10 kW system. The prices come from the EnergySage table above. The annual savings figure is an assumption for illustration, not a forecast.

Assumptions: price $2.58 per watt; no state incentives; no loan interest; annual electricity savings of $2,400 (about $200 per month); the buyer could use the full credit.

The credit used to remove about $7,740 from this bill. For context, IRS data for tax year 2023 (as summarized by NAHB) showed an average claimed solar cost of $27,355 and a credit of about $8,200.

The result, about 10.8 years, is close to the roughly 10-year average payback EnergySage reports nationally. Your number depends on your electricity rate, how much of your solar you use yourself, and what your utility pays for exports. A high-rate state pays back faster. A low-rate state pays back slower. Put your own annual savings into the formula:

Payback (years) = net cost ÷ annual savings

Figures are estimates. Get quotes from licensed installers before you decide.

Leases and PPAs: what is left of the federal credit

The company that owns a leased or PPA system can still claim the commercial credit (Section 48E) and price some of it into your monthly payment. The deadline matters:

• Projects that began construction by July 4, 2026 qualify under the longer window.
• Everything else must be placed in service by December 31, 2027.

SolarReviews surveyed solar companies in early 2025 and found the average first-year lease cost was about $22 per kW per month. That is a 2025 data point, and its owners expected lease prices to ease. Another industry analysis warns that PPA prices in some regions could rise sharply once 48E ends. Treat both as forecasts.

Before signing a lease or PPA, check the annual escalator, what happens if you sell the house, and the buyout terms. Research on California home sales found that owned systems added roughly 5% to 10% to home value, while leased systems added little because the buyer inherits the contract.

What about batteries?

The old 25D credit covered qualifying batteries too, so a purchased battery now has no federal credit either. NRG Clean Power puts a typical 13.5 kWh battery at roughly $10,000 to $13,000 installed in 2026. Whether it pays off depends on your export rate and outage risk. Where your utility still pays good rates for exported solar, a battery is mostly a backup purchase, not a savings play.

State and local incentives matter more now

With the federal credit gone for buyers, state programs, utility rebates, property tax exemptions and net metering carry more weight. EnergySage lists Maryland, New York, Rhode Island, South Carolina and Washington, D.C. among the states with the strongest solar incentives. Check your state and utility rules before you compare quotes, because they can shift the answer more than panel brand.

Solar costs in the Gulf: what is verified

Gulf rooftop rules vary by country and sometimes by emirate, and several are changing. Here is what can be confirmed from official or primary announcements. Public price data in AED and SAR from independent sources is thin, so this guide does not quote a “typical” system price. Use the method at the end of this section instead.

Dubai (UAE)

Shams Dubai is DEWA’s net metering program. According to DEWA’s FAQ, surplus electricity that your system exports is credited and used to offset your future consumption. The incentive is lower bills, not a cash payment. All applications go through a DEWA-approved consultant or contractor, and DEWA inspects the system before the meter is installed. Ground-mounted systems were removed from the net metering scheme years ago, so residential projects are roof-based.

Abu Dhabi (UAE)

On March 31, 2026, the Department of Energy – Abu Dhabi launched the second phase of its Solar Energy Self-Supply Policy. For the first time it covers villas and residential buildings, and it lets them generate and store electricity from rooftop solar and connect to the grid. The announcement describes simplified procedures and standardized technical requirements. Details on export compensation were not in the sources reviewed, so confirm them with the DoE and your utility before relying on any payback estimate.

Saudi Arabia

Saudi Arabia’s regulator, SERA, proposed a self-consumption framework on October 20, 2026. As proposed, surplus electricity would be credited at SAR 0.07 per kWh (about $0.019) for residential customers in the first two categories, with credits valid for 12 months. Systems up to 11 kW would be exempt from demand and grid connection charges. This is a draft. Rules may change before they take effect, so do not build a final decision on it.

The lesson for any Gulf buyer: when exports earn little or only offset future bills, your savings depend mostly on how much of the solar power you use yourself. Size the system to your daytime consumption, not to your roof.

Other Gulf states

Bahrain’s net metering has operated since 2017 and gives energy credits rather than cash, according to an OGN News analysis. For Kuwait, Qatar and Oman, the independent public information found while preparing this guide was limited and mostly from commercial blogs, so check with your national regulator or utility before you plan.

Heat and dust change the math

Heat and dust reduce output in the Gulf, and quotes should account for both.

• Heat: panel output falls as panels get hotter. A typical module might lose about 0.4% of power per °C above 25°C. One manufacturer example shows roughly 16% lower output at a 65°C module temperature. Ask for the temperature coefficient on the datasheet. A lower (less negative) number is better.
• Dust: a UAE study found that up to 13% of power can be lost to dust without regular cleaning. A Sharjah experiment measured soiling loss rising by 12.7% over five months of dust build-up. Budget for cleaning and ask how your installer models it.

How to get a fair Gulf price

1. Get at least three written quotes from licensed or utility-approved installers (DEWA-approved in Dubai).
2. Divide each total by the system size in watts to get the price per watt in your currency.
3. Ask for expected annual production in kWh, including heat and dust assumptions.
4. Compare against your own bills: annual savings = kWh you use yourself × your tariff, plus any credit value.
5. Divide net cost by annual savings to get your payback.

Currency note: the UAE dirham is pegged at about AED 3.67 per USD, and the Saudi riyal at SAR 3.75 per USD.

Solar costs in the UK

In Great Britain, installations of home solar and batteries are VAT-free (0%) until March 31, 2027. From April 1, 2027 the rate returns to 5%, according to HMRC’s manual and industry bodies. Northern Ireland follows different rules.

A secondary guide using MCS-certified installation data from February 2026 puts the typical system for a three-bedroom home at about £7,279. Another source cites a DESNZ median of £7,504 for a 4 kW system in 2024/25. On a £7,279 system, the move from 0% to 5% VAT would add roughly £364 if the price were otherwise unchanged. Real quotes may move for other reasons too, so ask any installer what VAT rate is in your quote and what happens if installation slips past March 31, 2027.

You can also earn from exports through the Smart Export Guarantee (SEG), which has no end date. Rates vary by supplier, and a smart meter that records exports is required. The Warm Homes Plan, announced in January 2026 with £15 billion in funding, targets eligible households rather than everyone. Check gov.uk for current eligibility.

How to compare solar quotes in 2026

A fair quote shows:

• System size in kW and the price per watt
• Modeled annual production in kWh
• Panel and inverter brands and model numbers
• Warranty terms for equipment, workmanship and roof penetrations
• A cash price and a financing breakdown, including any dealer fees
• Panel layout and shading assumptions
• Permitting and grid-connection timeline

Warning signs include no production estimate, pressure to sign today, a loan quote with no fee disclosure, and savings based on unrealistic electricity-price growth.

Frequently asked questions

Is there still a 30% federal solar tax credit in 2026?

Not for homeowners who buy their system. The Section 25D credit does not apply to expenditures after December 31, 2025. Companies that own leased or PPA systems may still claim the commercial 48E credit under a December 31, 2027 placed-in-service deadline.

Are solar panels still worth it without the tax credit?

Often yes, but payback is longer. In our 10 kW example, simple payback moves from about 7.5 to about 10.8 years at the same savings. The result depends on your electricity rates, export rules and state incentives.

How long is the payback period in 2026?

EnergySage reports an average of about 10 years in the US. In the Gulf and UK it depends on your tariff and export rules, so calculate it from your own bills.

Is a lease or PPA cheaper than buying now?

It can lower your upfront cost and may include a share of the federal credit, but total savings are usually lower than owning. Check escalators and resale terms.

What changed for home solar in the Gulf?

Abu Dhabi extended its self-supply policy to homes on March 31, 2026. Saudi Arabia’s regulator proposed a net billing framework on October 20, 2026 that is still a draft. Dubai’s Shams Dubai net metering credits exports against future bills.

Final note

All prices, incentives and regulations above are dated and can change. Figures are estimates, not offers. Get quotes from licensed installers and confirm current rules with your tax adviser, utility or regulator before you buy.
