How Alabama compares to the rest of the US
Two numbers drive solar economics: your electricity rate and how much sun your roof gets. Here's where Alabama stands against the national average.
| Electricity rate | $0.15/kWh (10% lower than the $0.17 US avg) |
| Daily peak sun hours | 4.5 (1% more than the 4.5 US avg) |
| Net metering | Limited / utility-specific |
Alabama enjoys plenty of sun but relatively cheap electricity. The abundant sunshine means a smaller system can cover your usage, though the lower rates mean each kWh you save is worth a bit less — so the bigger your monthly bill, the better solar pencils out.
