Alabama solar notes
Alabama Power imposes a controversial monthly capacity fee (~$5/kW) on solar customers and pays only avoided-cost rates for exports, one of the weakest net-metering setups in the South.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and Alabama may offer its own incentives — check locally.
