Is Solar Worth It in Alabama in 2026?
Alabama gets a fair amount of sun — Birmingham panels produce around 1,382 kWh per installed kilowatt per year, a solid number for the Southeast. But sun isn't the problem here. Two other things are, and both matter more than they do in almost any other state.
First, the federal 30 percent tax credit that used to make the math work is gone, repealed for any system completed after December 31, 2025, with no phase-out. Second — the part most sales pitches leave out — if you're an Alabama Power customer, going solar means a monthly Capacity Reservation Charge of $5.41 per kilowatt of panels installed, on top of an export rate for extra power that runs a fraction of what you pay to buy electricity back. A federal judge upheld that charge in March 2026, so it isn't going anywhere soon. Between the missing credit, the weak buyback rate, and a fee that exists only because you have solar, Alabama is one of the harder states in the country to make rooftop solar pencil out. It can still work if your bill runs high and you use nearly everything you generate yourself — but run your own numbers here, not an installer's slide deck.
Alabama Electricity Prices Keep Climbing
Solar only pays off if it offsets electricity that would otherwise cost you money, so start with where Alabama rates have been. Here's the last two decades, from federal EIA data.

Alabama households paid about 16.1 cents per kWh in 2025 (EIA preliminary) — roughly double the 2005 rate, a 101 percent increase over 20 years, with the last decade compounding at about 3.2 percent a year. That's real money leaving your account every month, and it's why self-consumption still matters even where export credit is weak: every kWh your panels make and your house immediately uses is a kWh you didn't buy at 16.1 cents. The rate trend argues for solar. Nearly everything else on this page argues for caution.
The Alabama Sun, Month by Month
Alabama sits at roughly 33°N — solidly mid-South, with decent sun angles year-round and none of the harsh winter shortfall you'd see further north. Birmingham gets an estimated 213 sunny days a year, enough to make production respectable even if it will never rival Arizona or Florida.

Production peaks in late spring and holds up through fall, with a predictable winter dip. Because Alabama Power's export compensation is weak, that seasonal swing matters less for banking credits and more for timing your own usage — running the dishwasher, EV charger, or AC during peak-production hours captures far more value than exporting the same kWh ever will.
What Solar Costs in Alabama in 2026
Alabama installs run about $3.69 per watt on average as of mid-2026 (EnergySage marketplace data) — on the higher side nationally, and with no federal credit left to offset it for a buyer-owned system.
| System Size | Typical 2026 Cost | Roughly Offsets | Alabama Power CRC |
|---|---|---|---|
| 5 kW | $16,600 to $20,300 | ~6,900 kWh/yr (~$93/mo at 16.1¢) | ~$27/mo ($325/yr) |
| 8 kW | $26,600 to $32,500 | ~11,100 kWh/yr (~$148/mo) | ~$43/mo ($519/yr) |
| 12 kW | $39,900 to $48,700 | ~16,600 kWh/yr (~$223/mo) | ~$65/mo ($779/yr) |
That last column isn't optional for Alabama Power customers — it's a standing monthly charge for having solar at all, separate from anything you save or export. Weigh it against your expected savings before signing. The state's average-size system (about 14.6 kW) runs roughly $45,700 to $61,800 installed, all before incentives — and as the next section covers, there's very little incentive left to apply.
Estimate Your Alabama Payback
The calculator below is set to Alabama's average electricity rate and Birmingham-area sun production. Enter your own monthly bill to see an estimated system size, payback period, and 25-year outlook. Alabama rates have grown about 3.2 percent a year over the last decade — a reasonable starting point for the inflation field — though you should mentally subtract the Capacity Reservation Charge, which this tool doesn't model automatically.
Alabama Solar Incentives in 2026
This is a short section, and that's the honest answer.
- Gone — the 30 percent federal credit: The Residential Clean Energy Credit ended for systems completed after December 31, 2025. There's no state credit to fall back on — Alabama has no state income tax, so it never ran one.
- No state rebate program: Alabama has no statewide residential solar rebate. A few co-ops (Central Alabama Electric, Dixie Electric) offer small general efficiency rebates, but nothing solar-specific.
- No dedicated sales tax exemption: Alabama's pollution-control exemption targets industrial equipment, not rooftop solar. Assume standard state and local sales tax applies — commonly 8 to 10 percent combined.
- Partial — local-option property tax exemption: State law lets, but doesn't require, counties and cities exempt the added value of a solar system from your assessment, for up to 10 years and renewable for up to 10 more, minus the school-funding portion. Confirm with your county tax assessor that your jurisdiction has actually adopted it.
- Leases and PPAs: Third-party-owned systems can still capture a separate federal business credit (Section 48E) through 2027, but it belongs to the leasing company, not you. It may lower your lease rate, or it may not — compare against a cash or loan purchase before assuming it's the better deal.
Rate PAE: How Export Credit Works in Alabama
Alabama has no statewide net metering law requiring utilities to credit exported solar at retail rate. Alabama Power — the dominant investor-owned utility, serving about 1.4 million customers — compensates exports instead under Rate PAE (Purchase of Alternate Energy) for systems under 100 kW (larger systems use Rate CPE). PAE is an avoided-cost tariff, last reset by a Public Service Commission order dated March 4, 2025 (Docket 18005), paying roughly 3 to 5 cents per kWh depending on season and time of day — about 4.7 to 4.9 cents at summer weekday peak, closer to 3 to 3.6 cents off-peak. Against the 16.1 cents you pay to buy power, exported solar is worth roughly a quarter to a third of what it costs to avoid buying.
On top of that, Alabama Power charges self-generation customers a Capacity Reservation Charge — $5.41 per kW of installed solar capacity every month, a standby fee in place since 2020 (up from $5.00 set in 2012). For a 5 kW system that's roughly $325 a year, or about $9,000 over 30 years, regardless of how much you export or consume. The Southern Environmental Law Center sued over the charge as a PURPA violation; on March 25, 2026, a U.S. District Court judge in the Middle District of Alabama granted summary judgment for Alabama Power and the PSC, upholding the fee. Absent an appeal, that fight is effectively over. Rural co-ops and municipal utilities set their own buyback and interconnection terms — there's no PSC-mandated statewide rule they must follow, and in practice their terms tend to be similarly unfavorable. Confirm the specifics with your utility before signing anything.
Why Alabama Payback Runs Longer Than the Sun Alone Suggests
Alabama isn't short on sunshine or rising electricity prices — both usually point toward solar making sense. What actually holds it back is policy layered on top of the resource: a buyback rate around a quarter of retail, and a monthly per-kW fee that exists only because you generate your own power. Together they mean your return depends almost entirely on how much of your own production you consume directly, in the same hour it's made, rather than how much you export. A homeowner who runs the AC, laundry, and an EV charger during peak sun hours will see a meaningfully better return than one who's away at work all day exporting most of their output at 4 cents a kWh. Ask every installer to model your actual daytime usage pattern, not a generic annual offset number — in Alabama that distinction is the difference between a reasonable payback and a genuinely long one.
How to Go Solar in Alabama
If you've read this far and the math still looks interesting, work through these steps in order.
- Pull your last 12 power bills and calculate your average monthly cost and how much usage happens during daylight hours.
- Confirm your roof faces south, east, or west with minimal shading and has at least 10 to 15 years of life left. Replace an aging roof before you install, not after.
- Ask your utility which export tariff applies to you (Rate PAE, Rate CPE, or a co-op/municipal rate) and get the current per-kWh figures in writing.
- If you're an Alabama Power customer, have the installer show the Capacity Reservation Charge math for your system size as a permanent line item against your projected savings.
- Ask your county tax assessor whether your jurisdiction has adopted the local-option property tax exemption.
- Get at least three quotes, compare price per watt and warranties, and confirm none assumes a federal credit that no longer exists for a buyer-owned system.
