What the planet gets
Net metering credits exported power against what you draw from the grid. Rates vary by state, California's NEM 3.0 pays much less for exports than 1:1 states.

16¢/kWh
US average: 17¢/kWh
Cheaper power means each solar kWh saves less
Solar generation
~4.3 kWh/kW/day
US average: ~4.5 kWh/kW/day
Less sun per panel than the US average

18.2 years
US average: 10.6 years
Slower than the US average on a $150 bill
Solar cost & savings by system size in Alabama
Computed with Alabama's rate (16¢/kWh), sun (~4.3 kWh/kW/day), and its reduced export credit, at the 2026 national benchmark of ~$2.75/W with no federal credit.
| System size | Installed cost | Generation/mo | Annual savings | Payback |
|---|---|---|---|---|
| 4kW | ~$11,000 | ~516 kWh | ~$604 | ~18.2 yrs |
| 6kW | ~$16,500 | ~774 kWh | ~$907 | ~18.2 yrs |
| 8kW | ~$22,000 | ~1,032 kWh | ~$1,209 | ~18.2 yrs |
| 10kW | ~$27,500 | ~1,290 kWh | ~$1,511 | ~18.2 yrs |
Savings assume a home large enough to use this output. Figures last reviewed July 2026,size a system from your actual bill instead.
How exports are paid in Alabama
No statewide net metering; utilities credit exports near avoided-cost rates and may add a solar capacity fee.
Because Alabama pays less than the full retail rate for exported power, the numbers reward using more of your own solar, running big loads in daylight, or adding a battery to store the surplus instead of exporting it cheaply.
Policies change often, always confirm current rules with your utility or at DSIREbefore deciding.
Alabama solar FAQs
Is solar worth it in Alabama in 2026?
For a typical $150/month bill, we estimate a Alabama system pays for itself in about 18.2 years, with no federal tax credit assumed (the residential credit expired at the end of 2025). At 16¢/kWh with limited / utility-specific, the case is workable but depends on your roof, usage pattern, and quotes.
How much does a solar system cost in Alabama?
At 2026 benchmark prices (~$2.75/W), a 6kW system runs about $16,500 installed, generating roughly 774 kWh a month in Alabama's sun. Local quotes vary 20-40% between installers, so always collect several.
What is the net metering policy in Alabama?
No statewide net metering; utilities credit exports near avoided-cost rates and may add a solar capacity fee.
Does Alabama have a state solar incentive?
Sizing to maximise self-consumption matters most here. Since the federal residential credit ended in 2025, state and utility incentives are the main upfront help available.
How many solar panels do I need in Alabama?
A 7.5 kW system suits a typical $150/month bill in Alabama, that's roughly 18 modern 425W panels needing about 488 sq ft of unshaded roof. Enter your own bill in the calculator above for a precise size.
