Louisiana vs Mississippi Solar Incentives: Which State Gets the Better Deal?
Side-by-side comparison of Louisiana and Mississippi solar incentive programs in 2026: state tax credits, net metering rules, exemptions, payback period, and projected 25-year savings.
| Metric | LA · Louisiana | MS · Mississippi |
|---|---|---|
| Avg Monthly Bill | $195 | $185 |
| Peak Sun Hours / Day | 4.9 | 4.9 |
| Avg $/Watt Installed | $2.85 ◆ | $3.05 |
| State Tax Credit | None | None |
| Net Metering | retail | None |
| SREC Market | No | No |

State Tax Credit Comparison
Louisiana offers no state income tax credit. Mississippi offers no state income tax credit.
Net Metering Policies
Louisiana: retail rate net metering active. Mississippi: no statewide net metering mandate.
Net metering is often the most economically significant solar policy because it determines how excess production is valued. Retail-rate states (where you receive full retail price for exported energy) have substantially better solar economics than avoided-cost or no-net-metering states.
Average 25-Year Savings
Louisiana: $34,700 over 25 years (avg payback 8.5 yrs). Mississippi: $27,100 over 25 years (avg payback 10.1 yrs).
Verdict: Which State Wins on Solar?
Louisiana edges out Mississippi on lifetime savings primarily due to more favorable net metering rules.
