State solar guide
Alabama solar economics in 2026 depend entirely on your utility rate, available state incentives, and net-metering rules. The federal residential credit expired December 31, 2025. We present the honest picture for your location.

Net metering
Alabama has no statewide net metering mandate. Alabama Power (a Southern Company subsidiary) offers Rate PAE (Purchase of Alternative Energy) for residential solar customers. Under Rate PAE, excess generation exported to the grid is purchased at a rate below retail, approximately 3 to 5 cents per kWh, compared to the retail rate of 16.18 cents per kWh. Self-consumed solar energy retains the full retail value. TVA-served areas in northern Alabama access the TVA Dispersed Power Production (DPP) program, which pays approximately 2 cents per kWh for exports - among the lowest in the country. The Rate PAE and DPP structures make grid export financially negligible, reinforcing the need for self-consumption system design.
Alabama Power (Southern Company) serves the majority of Alabama. Rate PAE export credit is approximately 3 to 5 cents per kWh. TVA-served northern Alabama communities access the TVA Dispersed Power Production program at approximately 2 cents per kWh. Rural electric cooperatives may have different terms. Verify current Rate PAE pricing directly with Alabama Power before finalizing system size and economics.

Savings example
This example uses real Alabama market data. No federal residential credit is applied. Figures are illustrative; your in-home assessment uses your actual utility bills and the current rate schedule for your specific utility.
System size 14.6 kW at $3.13 per watt (EnergySage May 2026). Annual production estimated at 19,000 to 23,000 kWh based on Birmingham area peak sun hours of 4.5 to 5.0. Assumes 80% self-consumption at 16.18 cents per kWh retail (high retail rate is primary savings driver) plus 20% exported at Rate PAE approximately 4 cents per kWh. Federal residential credit: $0 (expired). Figures are illustrative; your in-home assessment will use your actual utility bills and current Alabama Power rate schedule.

Permitting
Alabama does not have a statewide residential solar permit fee cap. Permit requirements and fees vary by local Authority Having Jurisdiction (AHJ). Major metro areas (Birmingham, Huntsville, Mobile) typically have permit timelines of 2 to 4 weeks. Alabama Power interconnection review adds 4 to 8 weeks. Alabama has no RPS and limited statewide solar policy infrastructure, meaning AHJ familiarity with solar varies by jurisdiction. Contract to energization typically runs 10 to 16 weeks.
Alabama Power's Rate PAE interconnection process is the primary path for residential customers. TVA-connected northern Alabama customers access a different interconnection process through their local power company. Confirm which utility serves your address before beginning the permit and interconnection process.
Commercial solar in Alabama
The commercial solar credit (Section 48E, 30 percent) remains available for qualifying commercial projects. Construction must begin by July 4, 2026 to qualify for the full placed-in-service window. Combined with MACRS accelerated depreciation and 100 percent first-year bonus depreciation, the combined first-year federal benefit can reach 45 to 55 percent of project cost for many Alabama business owners. Direct Pay is also available for nonprofits, municipalities, and other tax-exempt entities.
Commercial solar overviewCommercial solar projects must begin construction by July 4, 2026 to qualify for the 30 percent Section 48E federal tax credit. After that date, the system must be placed in service by December 31, 2027.
