State Tax Credit Comparison
North Carolina offers no state income tax credit. Tennessee offers no state income tax credit.
Net Metering Policies
North Carolina: retail rate net metering active. Tennessee: 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
North Carolina: $38,900 over 25 years (avg payback 8.1 yrs). Tennessee: $28,900 over 25 years (avg payback 9.6 yrs).
Verdict: Which State Wins on Solar?
North Carolina edges out Tennessee on lifetime savings primarily due to higher solar irradiance.
