An Alabama solar panel cost runs about $3.03 per watt in 2026, so a 6 kW system is near $18,200. It makes about 8,200 kWh a year in Birmingham, but Alabama Power’s $5.41 per kW monthly solar fee and no net metering stretch a cash payback to roughly 18 years. The federal tax credit ended December 31, 2025.
If you are pricing rooftop solar in Alabama, here is the honest 2026 math, and it is different from most states. An Alabama solar panel cost is about $3.03 per watt installed, the federal homeowner tax credit ended on December 31, 2025, and Alabama has no retail net metering. On top of that, Alabama Power charges rooftop solar customers a monthly fee tied to system size. That combination pushes payback well past what net-metered states see, so this page prices it straight: what a system costs, what it produces in the Birmingham sun, what the utility fee and export rules do to the return, and how long payback really takes. For Alabama’s full net-metering and incentive picture, see our Alabama solar guide.
What an Alabama solar panel cost looks like in 2026
Alabama sits a touch above the national average on price. EnergySage puts the state at about $3.03 per watt installed before incentives (EnergySage Alabama). Your real number moves with roof pitch, shading, panel and inverter choice, and how much you sign up in one contract, so treat the table below as a starting point and get written quotes to confirm.
| System size | Typical gross cost (at $3.03/W) | Best-fit home |
|---|---|---|
| 5 kW | About $15,200 | Smaller or efficient home, lower usage |
| 6 kW | About $18,200 | Average Alabama single-family home |
| 8 kW | About $24,200 | Larger home or higher electric use |
| 10 kW | About $30,300 | All-electric home, EV charging |

What an Alabama system produces, and what it really saves
Birmingham gets strong sun, but the utility rules cap the payback. According to MySolarFY’s analysis (August 2026), a 6 kW rooftop system in Birmingham (ZIP 35203) produces about 8,200 kWh a year and would offset roughly $1,375 on an Alabama power bill at the state residential rate of 16.77 cents per kWh, if every kWh replaced power you would have bought. We build that figure from NREL’s PVWatts production model and the EIA residential rate, not a sales estimate. But two Alabama-specific rules cut into that number, so read the next two sections before you bank on it.
| Figure | Value | Source |
|---|---|---|
| Alabama residential rate | 16.77 cents per kWh (May 2026 data) | EIA |
| 6 kW production, Birmingham (35203) | About 8,200 kWh per year | NREL PVWatts v8 |
| Alabama Power solar fee | $5.41 per kW per month, so about $390 a year on 6 kW | Alabama Power Rate Rider RGB |
| Net annual benefit (6 kW) | About $985 a year, before any export haircut | MySolarFY estimate (offset minus fee) |
| Simple payback (6 kW, cash) | About 18 years, often longer | MySolarFY estimate (cost / net benefit) |
The Alabama Power solar fee, and why it matters
Alabama Power charges rooftop solar customers a monthly fee, and it is real money. Under Rate Rider RGB, a residential customer with on-site generation pays a Capacity Reservation Charge of $5.41 per kW of installed capacity per month on standard secondary service (Alabama Power Rate Rider RGB). On a 6 kW system that is about $32 a month, or $390 a year, charged whether the sun shines or not. A federal court upheld the utility’s right to keep charging it in March 2026 (Alabama Reflector). That fee is the single biggest reason Alabama payback runs longer than in states without one, and you should confirm your own rate rider and fee with Alabama Power in writing before you sign. For the full account-level picture, see our Alabama Power solar and net metering guide.
No net metering: how Alabama pays for your extra power
Alabama does not have retail net metering, so exported power earns far less than you pay. When your panels send more power to the grid than your home is using, Alabama Power credits that excess at a wholesale avoided-cost rate. The utility’s own consumer solar guide says that rate can be “quite small, perhaps less than 2 cents per kilowatt-hour,” not the 16.77 cents you pay to buy power (Alabama Power Rate Rider RGB). The Alabama Public Service Commission did not adopt a retail net-metering standard, so there is no state rule forcing full-retail credit (Alabama Public Service Commission). The takeaway: a system that offsets power you use in real time earns full value, but every kWh you export is worth pennies. That is why oversizing hurts here, and why the payback above assumes self-use. For how the mechanics work in states that do offer it, see how net metering credits your solar exports.

What changed federally, and what it means for the cost
The 30% federal homeowner credit is no longer part of a 2026 Alabama quote. The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so an Alabama homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS). A system finished by that date could claim 30% on a 2025 return, but a 2026 buyer cannot, so run the numbers at full price. For the full timeline, see what the federal solar tax credit change means in 2026.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the homeowner. On a lease or PPA the provider owns the panels and files for that credit, while your benefit is a lower or fixed power price with little or no money down. That is a different path from a cash purchase, with different math, and it is covered in our solar financing and comparisons guide. The 25D homeowner credit, by contrast, ended after December 31, 2025.
How to make the Alabama math work
With the federal credit gone, a monthly utility fee, and no net metering, the levers that matter in Alabama are specific:
- Size to your daytime usage, not the whole roof. Because exports earn only pennies and the fee scales with system size, a system matched to what you use during the day returns far more per dollar than a big one.
- Count the solar fee in every quote. Ask each installer to show payback with Alabama Power’s $5.41 per kW monthly charge included, not left out.
- Compare at least three written quotes. The price-per-watt spread between installers is often wider than any single line item, so shopping is where the real savings live.
- Weigh cash versus a loan versus a lease or PPA. Each changes payback and who keeps the tax benefit. See the financial case for whether solar panels are worth it, and the checklists in our solar resources hub.

Frequently asked questions
How much do solar panels cost in Alabama in 2026?
About $3.03 per watt installed before incentives, according to EnergySage, so a typical 6 kW system runs near $18,200 and a 10 kW system near $30,300. Your real price depends on roof, equipment, and installer, so get written quotes. With the federal tax credit ended after December 31, 2025 and no state solar rebate, most 2026 Alabama buyers should price the system at full cost.
What is the payback period for solar in Alabama?
For a 6 kW cash purchase, simple payback is roughly 18 years, and often longer. That comes from a system near $18,200 producing about 8,200 kWh a year in Birmingham (NREL PVWatts) valued at 16.77 cents per kWh (EIA), then reduced by Alabama Power’s solar fee of about $390 a year and by the fact that exported power earns only avoided cost, not retail. Alabama payback runs longer than in net-metered states without a solar fee.
Does Alabama Power charge a fee for rooftop solar?
Yes. Under Rate Rider RGB, residential solar customers pay a Capacity Reservation Charge of $5.41 per kW of installed capacity per month on standard secondary service, about $390 a year on a 6 kW system. A federal court upheld the charge in March 2026. Confirm your exact rate rider and fee with Alabama Power in writing before you sign.
Does Alabama have net metering?
No. Alabama has no retail net-metering standard. Alabama Power credits power you export at a wholesale avoided-cost rate that its own consumer guide says can be less than 2 cents per kWh, far below the retail rate you pay. Because exports earn so little, a system sized to your real-time usage returns much more than an oversized one.
Is solar worth it in Alabama without the tax credit?
It can be, but the math is tighter than in most states. A payback near 18 years on a cash 6 kW system means solar can still save money over a 25-year panel life, especially if rates rise, but the utility solar fee and lack of net metering make honest sizing and quote-shopping essential. The answer depends on your usage, roof, and financing, so run your own numbers rather than trusting a single savings promise.
