Solar by state › Louisiana

Home solar in Louisiana

New rooftop systems since 2020 earn only the utility's avoided cost for power sent to the grid (Entergy Louisiana: about 2.6 cents/kWh), and the state solar tax credit is gone; the main state perk left is a property tax exemption.

Harder case for solarLouisiana has some of the lowest power prices in the U.S., exports earn a low wholesale-based credit, and no state rebate or tax credit is open. The property tax exemption helps a little.

Net metering Replaced by a lower credit

Under the PSC's 2019 rules, systems that applied or were installed after Dec. 31, 2019 use two-channel billing: you pay retail for all power you buy, solar you use at home saves the full retail price, and each kWh you export is credited at the utility's avoided cost, updated yearly (Entergy Louisiana: $0.0259331/kWh from April 1, 2025). Credits can't cut the bill below the customer charge and roll to the next month. Systems installed by Dec. 31, 2019 keep 1:1 net metering until Dec. 31, 2034. Home systems up to 25 kW qualify.

Federal tax credits

The 30% federal tax credit for homeowners who buy solar (Section 25D) ended for systems placed in service after December 31, 2025, so buying no longer earns a federal credit. If you lease or sign a power purchase agreement (PPA), the panels belong to a company that may still claim a business credit under federal deadlines that tighten through 2027. Ask your installer whether that savings is in your price.
