How Mississippi 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 Mississippi stands against the national average.
| Electricity rate | $0.13/kWh (22% lower than the $0.17 US avg) |
| Daily peak sun hours | 4.6 (3% more than the 4.5 US avg) |
| Net metering | Broadly available |
Mississippi 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.

Mississippi solar FAQ
How many solar panels do I need in Mississippi?
A typical Mississippi home needs roughly 20 standard 400-watt panels (about a 8 kW system) to offset its electricity use, given Mississippi's 4.6 daily peak sun hours. A higher bill or shadier roof pushes that number up.
Does Mississippi have net metering?
Yes — Mississippi broadly offers net metering, so the excess power your panels send to the grid credits your bill and improves your payback. Net metering with upfront performance incentive. Note: the federal residential solar tax credit was eliminated for new installations after December 31, 2025. Check your state's programs for available incentives.
What's the payback period for solar in Mississippi?
For a typical $117/month bill, the estimated payback is about 14.5 years, after which the power your panels produce is essentially free for the remaining ~10 years of the system's life.
