Net metering, tax credits and incentives in 2026
Louisiana pays less than retail for exported solar power. Under Avoided-cost net billing, power you send to the grid earns about 2.7¢/kWh, against 13.4¢ for power you buy. We assume 40% of a no-battery system's output is used at home as it's produced (worth the full price) and the rest is exported, so each solar kWh is worth about 7.0¢. Using more of your solar yourself, by running appliances midday or adding a battery, raises that.
Louisiana PSC rules since 2020 credit exports at the utility's avoided cost, about a quarter of retail. Entergy New Orleans customers may still have retail net metering. Source.
There is no federal tax credit for buying home solar installed in 2026. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so the costs and paybacks on this page include no federal credit.
Louisiana and local utilities may still offer rebates, performance payments, property-tax or sales-tax exemptions. Search the DSIRE incentives database for Louisiana and ask installers which programs they apply for you.
