Alabama Has No Mandatory Net Metering
Unlike most states, Alabama has never enacted a statewide net metering law. Utilities are not required to purchase your excess generation at any particular rate.
What This Means for You
Alabama Power buys exported energy under Rate PAE (Purchase of Alternate Energy), a PSC-approved tariff that implements federal PURPA avoided-cost purchases. Credit rates are reset periodically. TVA-served cooperatives in northern Alabama follow TVA's own avoided-cost programs. Rural cooperatives across the state set their own buyback terms. Verify your utility's current program before going solar.
Alabama Power, Rate PAE (Purchase of Alternate Energy)
Rate PAE is Alabama Power's voluntary program for customer generators up to 100 kW. Rates are time-of-use and seasonal. Source: Alabama Power Rate_PAE.pdf (official filed tariff, Tier 1).

One Bright Spot: Alabama Power Will Write You a Check
Under Rate PAE, if your accumulated credits exceed your charges, you can request a cash payment. This is unusual, most states that credit solar generation only allow bill credits that expire. Alabama Power's willingness to cut a check is worth noting, though the rate per kWh remains low.
Rate PAE Interconnection Fees
Systems 1 to 25 kW: no interconnection fee. Systems 25 to 100 kW: $500 one-time interconnection fee. Monthly base charge: $0.97/month (single-phase service). Annual program renewal, the tariff automatically renews unless you provide 30 days' written notice to cancel.
The Alabama Solar Math
With exports worth only 4.4 to 6.7¢/kWh against 14 to 15¢ retail imports, self-consumption dominates the economics.
Right-sized system: 90% self-consumption (Alabama Power territory, 8 kW, Birmingham)
| Category | Annual |
|---|---|
| Production | 10,800 kWh/yr (1,350 kWh/kW in AL) |
| Self-consumed (90%): 9,720 kWh × 14.5¢ | $1,409/yr savings |
| Exported (10%): 1,080 kWh × ~5.3¢ (blended) | $57/yr credit |
| Base charge (Rate PAE) | -$11.64/yr |
| Net annual savings | ~$1,455/yr |
| System cost (8 kW, no ITC) | ~$22,400 |
| Simple payback | ~15 to 16 years |
Alabama's Solar Advantage: High Production
Alabama averages 4.5 to 5.1 peak sun hours, more than most of the Midwest. A well-sited south-facing system in Birmingham or Mobile produces more kWh per panel than panels in Ohio or Indiana. High production helps offset the weak export rate, but doesn't fully compensate. Right-sizing for self-consumption remains the primary strategy.
All Alabama Solar Incentives
| Incentive | Status | Detail |
|---|---|---|
| Federal Tax Credit (ITC 25D) | EXPIRED | Section 25D expired December 31, 2025. Systems installed in 2026 or later do not qualify for the federal residential solar credit. |
| Alabama State Income Tax Credit | NONE | Alabama has never offered a state income tax credit for residential solar. No legislation pending as of mid-2026. |
| Statewide Property Tax Exemption | NONE | Alabama has no statewide property tax exemption for solar. Solar installations may increase your assessed home value. See local option below. |
| Local Property Tax Abatement | LOCAL OPTION ONLY | Alabama law lets cities, counties and industrial development authorities grant tax abatements to qualifying business projects, including some renewable energy facilities. These are not designed for residential rooftop solar. Ask your county assessor whether any local relief applies. |
| Sales Tax Exemption | NONE | Alabama's state and local sales taxes (combined typically 9 to 10%) apply to solar equipment purchases. No residential exemption exists. |
| Mandatory Net Metering | NO STATE LAW | Alabama has no statewide mandatory net metering law. Export compensation is at each utility's discretion. |
| Alabama Power Rate PAE | VOLUNTARY PROGRAM | Rate PAE credits exports at 4.41 to 6.73¢/kWh depending on season and time of day. Up to 100 kW systems. Cash payments available for credit balances. Source: Alabama Power Rate_PAE.pdf (Tier 1). |
| Utility Rebates | NONE | Alabama Power, TVA distributing utilities, and cooperatives do not currently offer solar rebates for residential customers. |
| USDA REAP Grants | FARM/RURAL BUSINESS ONLY | Agricultural producers and rural small businesses may qualify for USDA REAP grants covering up to 50% of project costs. Not available to typical homeowners. |
Alabama Solar Q&A
Why does Alabama pay so little for solar exports?
Alabama has no mandatory net metering law, so utilities aren't required to credit exports at retail. Alabama Power's Rate PAE is a voluntary tariff based on avoided cost, what the utility would otherwise pay to generate or buy that power wholesale. Avoided cost is far below what you pay at retail. The legal framework in Alabama gives homeowners very little leverage to demand higher rates.
Is Alabama Power the only option? What about north Alabama?
No. Northern Alabama, including Huntsville, Florence, Muscle Shoals, and Decatur, is largely served by local distributing utilities that buy power from the Tennessee Valley Authority (TVA). If you're in TVA territory, your utility's solar compensation follows TVA's Dispersed Power Production or other local programs. Rates and terms vary. Utilities like Huntsville Utilities, Athens Utilities, and Florence Utilities each have different policies. The Alabama Power Rate PAE does not apply to TVA-served customers.
Can I get a check from Alabama Power for excess solar credit?
Yes, Rate PAE explicitly allows cash payments for accumulated credits upon request. This is one of the better features of Alabama's solar framework, even though the underlying credit rates are low. If you have a large system or lower-than-expected consumption in summer, contact Alabama Power to request a payout rather than letting credits accumulate indefinitely.
Does solar affect my Alabama property taxes?
Potentially, yes. There is no statewide property tax exemption. If your county assessor decides solar increases your home's market value, your assessed value, and property tax bill, could rise. Some Alabama counties may not add solar value in practice, while others may. If your municipality or county has a renewable energy abatement program, applying before installation can protect you. Ask your county tax assessor's office before signing a solar contract.
Should I install solar in Alabama in 2026?
It can still pencil out, but it takes more care than states with retail net metering. You need: (1) high self-consumption, size for 85 to 90%+ of your load; (2) good sun exposure (Alabama has excellent solar resource); (3) an installer who runs honest math at Rate PAE credit rates, not inflated projections. Without the federal ITC in 2026 and with low export rates, the simple payback is 15 to 20 years in Alabama Power territory. If you plan to stay in your home long-term and have good roof exposure, it may still make sense. If you're comparing it to other states, know you're starting behind on incentives.
