Mississippi solar notes
Mississippi credits solar exports at avoided cost plus a small adder and offers a low-income solar bonus, but overall incentives remain thin.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and Mississippi may offer its own incentives — check locally.
