Solar in Louisiana: how the rules work
How Louisiana credits the power solar panels send back to the grid, what homes there pay for electricity, and what to check when a home with solar is bought or sold.
How exported power is credited
Power sent to the grid is credited at an export rate well below retail, often tied to the utility’s avoided cost.
Under the LPSC General Order of September 19, 2019, customers who installed or applied after December 31, 2019 are on two-channel billing. All grid purchases are billed at retail, self-consumed solar offsets retail, and every exported kWh is credited at the LPSC avoided-cost rate: the 12-month average LMP, updated each April. Entergy Louisiana's rate is $0.0259331/kWh effective April 1, 2025, down from $0.0619905 in April 2023. The bill can go down to the customer charge or minimum bill, with leftover credit carried to the next month. Systems installed by December 31, 2019 keep 1:1 retail net metering with monthly rollover through December 31, 2034. That status transfers with the property but is lost on material modification. No solar-specific fixed fee was identified. Share basis: ~2.6 cents vs ~11-12 cents residential retail. The 2026 avoided-cost update was not located.
What changes for a home with solar
A savings estimate that assumes full retail credit for exported power overstates the value of that power for systems on the current rules. Power used in the home still offsets the full retail rate.
Older systems are often grandfathered on earlier, better terms for a set number of years. Which rules a particular system is on depends on its interconnection date, stated in the note above.
Electricity here costs about 13.4¢ per kWh (2026) and has risen about 2.1% a year over the last decade. A lease or PPA escalator above that pace makes the solar payment rise faster than utility rates have.
When a home with solar is sold in Louisiana
- Owned outright: proof it is paid off, the warranties, and the utility’s interconnection or net-metering agreement, which has to move into the buyer’s name.
- Loan: a payoff letter, and whether the buyer can assume the loan. Many solar loans are secured by a UCC-1 fixture filing that title will find.
- Lease or PPA: the transfer process and how long approval takes, the buyer’s credit check, the current payment or rate and its yearly increase, and a buyout quote.
- Every case: whether the export-credit terms above stay with the home after the sale, and the last 12 months of production from the monitoring app.
