Solar in Alabama

Alabama has no statewide net metering law. Export compensation is set utility by utility, and the dominant provider — Alabama Power — credits solar exports through its Solar Generation Buyback at a reduced rate well below retail. The northern counties served by the Tennessee Valley Authority fall under TVA's own dispersed-power and green-generation programs, which are likewise not retail-rate net metering. There is no state income tax credit, no SREC market, and no statutory property or sales tax exemption for solar equipment.

With the federal Section 25D residential credit expired (December 31, 2025), the only structural federal lever for 2026 owned systems is gone; leased and PPA arrangements may still access Section 48E through July 6, 2026. The policy direction has been neutral to cautious — Alabama has expanded utility-scale solar to meet corporate procurement goals but has not adopted residential-friendly export terms. Homeowners should model the system against Alabama Power's current buyback (or their TVA distributor's terms), size for self-consumption, and verify the interconnection tariff before committing.

Alabama's 5.2 peak sun hours place it among the sunniest states east of the Mississippi. The southern tier — Mobile, Dothan, the Gulf coastal plain — routinely exceeds 5.5, while the Appalachian foothills around Huntsville and the northern valleys run a touch below. Production is exceptionally even across the year, with long, humid summers driving heavy air-conditioning load that aligns naturally with midday solar output, and winters mild enough to keep shoulder-season generation productive.

Because Alabama Power's buyback pays only a few cents per exported kilowatt-hour, the design objective is to maximize on-site consumption rather than raw export volume. A system matched to daytime household load — particularly afternoon air-conditioning — captures the full $0.16/kWh retail value of every panel, whereas surplus pushed to the grid earns back a fraction. West and southwest orientations that carry production into the late-afternoon cooling peak can outperform pure south-facing arrays on a dollar basis. For TVA-territory customers in the north, the sizing logic depends on the specific TVA program in force, which has historically been less generous than retail net metering.

At $2.70/W, Alabama is among the cheaper markets for installed solar, with a typical 8 kW system around $21,600 before incentives. The 30% federal residential credit (Section 25D) ended December 31, 2025, and Alabama layers on no state tax credit, no property tax exemption, and no sales tax exemption, so there is effectively no structural offset beyond the federal 48E route available to leased or PPA systems beginning construction before July 6, 2026.

That sparse stack is why the buyback rate and system sizing carry the entire economic case. Payback near 11.5 years on the 8 kW model is respectable, but it depends on the household consuming most of its production at the full retail rate rather than exporting at the reduced buyback. Households with high daytime consumption — home-based workers, retirees, or those pre-cooling in the afternoon — fare best. Batteries are not subsidized here, so they are justified on outage-resilience grounds (Alabama's severe weather and tornado seasons) rather than tariff arbitrage.
