What Alabama does not have
No federal residential tax credit. Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase receives nothing at federal level.
No state solar tax credit. Alabama has never offered one, so nothing at state level replaced the federal credit.
No retail-rate net metering. Exported electricity is bought at roughly 3 to 5 cents per kWh against a retail rate closer to 16.
And on an Alabama Power account, a Capacity Reservation Charge of $5.41 per kW of installed capacity per month, upheld by a federal district court in March 2026.
What it does have
Good sun and low installed costs. Alabama averages around $2.80 per watt installed, among the lower figures in the country, and the solar resource is genuinely strong.
A retail rate closer to 16 cents per kWh, which is above the national average and makes each kilowatt hour of self-consumed generation worth more than it would be in Iowa or Washington.
Heavy summer air conditioning, which is a large daytime load that absorbs generation at full retail value exactly when the array produces most.
Those three together are what a viable Alabama project is built on. They are enough for many homes, but only if the design concentrates value where it exists.
What a viable design looks like here
Sized tightly to daytime consumption rather than to annual usage, because capacity costs $65 per kilowatt per year in charges and surplus earns 3 to 5 cents.
Paired with load shifting, so that as much generation as possible lands inside household demand at the full retail rate.
Quoted with the Capacity Reservation Charge shown as an explicit annual line, so the net savings figure is honest rather than gross.
And stress-tested. Ask to see the projection at a lower self-consumption share and at zero rate escalation. If it survives both, the case is real; if not, you have learned what it was resting on.
Costing it out with the recurring charge included
Strike the federal residential credit from any quote showing it, and do not expect a state credit in its place, because Alabama has none.
Rebuild from retail value for self-consumed generation at around 16 cents per kWh, 3 to 5 cents for exports, and the Capacity Reservation Charge at $5.41 per kW per month if you are on Alabama Power.
Ask your county assessor how residential solar is treated for property assessment at your address, since that is administered locally.
Then ask for that version in writing with all three lines visible. A quote that cannot show them separately is a quote you cannot check.
