Trevor has worked in home improvement and residential solar since 2016 and maintains the EcoGen Solar Cost Index.
Alabama has good sun, electricity about 8.5% cheaper than the US average, and the hardest solar math in the South. For most Alabama Power customers the answer is no; for the roughly four in ten households billed by a TVA distributor, a municipal utility or a co-op, the answer starts from different rules. What drives it is one line item: Alabama Power bills solar customers a monthly charge based on the size of their system, whether or not they use the grid that month. It comes to about $646 a year on the typical system, so ask whether your quote shows Rider RGB as a line item.
The Charge That Reverses the Arithmetic
Alabama has no statewide net metering. Alabama Power, which serves roughly 57% of households here, buys exported power under Rate PAE at time-of-day rates running about 3.05¢ to 4.93¢ depending on season and hour, against a retail rate near the 16.38¢ statewide average (Alabama Power files its own residential rate; the figure on your bill is the one you offset). That gap alone would make Alabama difficult.

Rider RGB is what makes it prohibitive. It applies a back-up charge of $5.41 per kW of nameplate capacity per month to customers with on-site generation. It is not a fee for power you draw. It is a standing charge for owning the array.
| Line | Annual effect on a 9.95 kW Alabama system |
|---|---|
| Power the house uses directly, valued at the 16.38¢ statewide average | Worth roughly $1,900 at high self-consumption |
| Power exported, at Rate PAE | Worth roughly 4¢ per unit, a quarter of retail |
| Rider RGB back-up charge | Minus about $646 every year, regardless of output |
Roughly a third of the best-case gross saving is removed before the first bill arrives. Worse, the charge scales with system size rather than with anything you produce or consume. A cloudy year does not reduce it; the only lever is nameplate, so a smaller array sized to daytime use is the design the tariff tolerates.

What That Does to Payback
A typical Alabama system runs 9.95 kW at about $31,641, among the largest in the country because households here use around 1,143 kWh a month. It produces roughly 13,711 kWh a year.
Share your house uses directly | Value after Rider RGB | Simple payback |
|---|---|---|
Around 85%, a very well-matched system | $1,345 | 24 years |
Around 60% | $921 | 34 years |
Around 40%, out during the day | $581 | 54 years |
Rerun the top row with the rate on your own Alabama Power bill; a lower filed rate lengthens every figure here. If someone is home most weekdays and the house runs daytime cooling, a water heater or a pool pump on a timer, you are near the 60% row; an empty weekday home with no load shifting is the 40% row; the 85% row needs a battery or a system sized well below your usage.
Panels carry production warranties around twenty-five years. Only the top row of that table returns its cost inside the warranty, and it describes a household that is home nearly all day with a system sized precisely to its load. The middle and bottom rows describe most people, and for them the equipment wears out before it pays for itself. Even the top row only returns its cost if you own the home for roughly 24 years; sell sooner and you are relying on resale value to recover the balance.
The Market Is Already Saying This
Alabama homeowners have been voting with their money. Installed residential rooftop capacity here stands at roughly 3.5 MW and fell 14.4% over the past year, one of only two that shrank among the 17 states with no third-party ownership market.
For scale, Arkansas next door has about 169 MW and grew 18.7% over the same period, on cheaper electricity and comparable sun. The difference is the tariff.
A shrinking market also compounds the problem, because fewer installations mean fewer installers competing and higher travel cost per job. Alabama’s installed price of $3.18 per watt is among the highest anywhere, and a contracting market is unlikely to bring it down.
There Is No Incentive Coming to Fix This
Worth stating plainly, because hope about incentives is what keeps bad Alabama quotes alive.
- No Alabama state solar tax credit, no statewide rebate and no state performance payment. There is nothing at state level to offset any of the above.
- The federal residential credit is $0 for purchased systems whose installation is completed after December 31, 2025, under Public Law 119-21. An Alabama quote showing 30% off is describing rules that no longer exist.
- Residential power purchase agreements are prohibited in Alabama, which closes the third-party route to the separate Section 48E business credit. Any no-money-down offer here is an offer of a prohibited contract; walk away.
Where the Answer Changes
Three situations genuinely differ from everything above.
- Northern Alabama, in TVA territory. Rider RGB is an Alabama Power tariff and does not apply. TVA offers an optional sale of output at avoided cost through its Dispersed Power Production arrangement, with no stated residential rate per kilowatt-hour. The back-up charge disappears. Strip the $646 charge and the same three rows shorten to roughly 16, 20 and 26 years at the same assumptions, before your local power company’s own retail and export rates are applied, so ask for both in writing and rerun the top row.
- A municipal utility or cooperative. Huntsville Utilities, Baldwin County Electric and others set their own terms. None of the Alabama Power numbers above describe your bill, and the only way to find out is to ask them directly.
- Someone whose priority is not the money. Backup power through an outage, or emissions, are legitimate reasons to install and they do not need a payback to justify them. Name that as the reason and judge the proposal on it.
The Question to Ask First
Before anything else: does Rider RGB apply to me, and what will it cost per month on the system being proposed? Any Alabama installer working in Alabama Power territory knows the answer. Ask whether the quote shows Rider RGB as a line item; a proposal that leaves it out has a savings figure wrong by several hundred dollars a year.
If the answer is that it applies, the figures above are your figures. Our Alabama incentives guide covers what the state does and does not offer, and the Alabama installer list covers who works here if your circumstances are among the exceptions.
Ask for the back-up charge as a line item before you compare any two quotes.

Alabama Power or a TVA Distributor: The Two Lines That Set Your Payback
If Alabama Power bills your house, two tariff lines decide the answer. Rider RGB charges $5.41 per kW of nameplate every month, about $646 a year on a typical 9.95 kW system, whether or not the array produces. Rate PAE then buys anything you export at 3.05¢ to 4.93¢/kWh, about a quarter of the 16.38¢ statewide average you avoid on power used at home. Make the company model your Alabama Power rate, Rider RGB as its own line, and the Rate PAE export credit in writing. In TVA territory, Huntsville Utilities included, the back-up charge does not exist, so ask that distributor for its own export terms instead.
Alabama Solar FAQs
Are solar panels worth it in Alabama?
For most Alabama Power customers, no. Our modeling puts simple payback between about 24 and 54 years depending on how much output the house uses directly, against equipment warranted for around 25. The reason is Rider RGB, a back-up charge of $5.41 per kW of nameplate capacity per month that costs about $646 a year on a typical 9.95 kW system regardless of what the panels produce. Northern Alabama in TVA territory is a different case.
What is the Alabama Power solar fee?
Rider RGB is a back-up charge of $5.41 per kW of nameplate capacity per month applied to customers with on-site generation, in effect since April 2022. It applies whether or not you draw power from the grid in a given month. On a 9.95 kW array it works out to roughly $646 a year, and because it scales with system size rather than output, a cloudy year does not reduce it; the only lever is nameplate, so a smaller array sized to daytime use is the design the tariff tolerates.
Does Alabama have net metering?
No. There is no statewide net metering law. Alabama Power buys exported power under Rate PAE at time-of-day rates of roughly 3.05¢ to 4.93¢ per kilowatt-hour depending on season and hour, against a retail rate near the 16.38¢ statewide average (Alabama Power files its own residential rate; the figure on your bill is the one you offset). That means power leaving your property is worth about a quarter of the power you would otherwise buy, before the Rider RGB charge is applied on top.
Why is Alabama rooftop solar shrinking?
Installed residential capacity in Alabama is roughly 3.5 MW and fell 14.4% over the past year, one of only two declines among the 17 states with no third-party ownership market. Arkansas next door has about 169 MW and grew 18.7% on cheaper electricity and comparable sun, so the difference comes down to the tariff. A contracting market also keeps installed prices high, and at $3.18 per watt Alabama is among the most expensive places to buy a system.
Are there any Alabama solar incentives?
None at state level. Alabama has no state solar tax credit, no statewide rebate and no state performance payment. The federal residential credit under Section 25D is $0 for purchased systems whose installation is completed after December 31, 2025 under Public Law 119-21, and residential power purchase agreements are prohibited in Alabama, which closes the third-party route to the separate Section 48E business credit.
Methodology: figures use the EcoGen Solar Cost Index for Alabama, $3.18 per watt as of March 1, 2026, 9.95 kW producing 13,711 kWh a year, self-used power valued at the 16.38¢ statewide average (labeled context; your Alabama Power rate governs), exports at an assumed 4¢ average inside the Rate PAE 3.05¢ to 4.93¢ band, Rider RGB at $5.41 per kW-month, and no federal residential credit. Payback figures are simple payback before financing, rate escalation (the state five-year average is 3.91%) and degradation. The 4¢ export average is generous if most of your exports land in off-peak hours.
