Utility rules and programs for Lafayette
Lafayette Utilities System (LUS), SLEMCO and Entergy Louisiana serve Lafayette County, so which rules apply depends on your address.
| Utility | Type | Solar export rule |
|---|---|---|
| City of Lafayette | city-owned | Lafayette Utilities System publishes an electric net metering rate sheet (December 2025 rate book, citing city ordinance section 94-209). We could not read its credit terms, so ask LUS before you buy. |
| Southwest Louisiana E M C | member-owned cooperative | SLEMCO exports are credited at avoided cost, $0.03930 per kWh (LPSC list, February 2026). We could not read SLEMCO’s own rider, so confirm its application steps and fees. |
| Entergy Louisiana LLC | investor-owned | Under Rider DG (systems requested or installed after 2019) you pay retail for power you buy, nothing for solar you use on site, and exports are credited at the avoided-cost rate, $0.0386407 per kWh from April 1, 2026; leftover credit carries forward. A one-time $100 meter charge applies. Systems in by 2019 keep one-for-one net metering through 2034. Homes are limited to 25 kW. |
Program details are from each utility’s own pages (read October 2026). See the Louisiana incentives table for statewide credits and a status for every program.

Solar Panel Installation in Lafayette FAQs
Is solar worth it in Lafayette?
The sun is strong (about 1,350 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Louisiana incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Louisiana’s state solar income tax credit has ended (Act 413 of 2017), but home solar equipment is exempt from property tax (R.S. 47:1706).
Do I need a permit for solar panels in Lafayette?
Usually yes, and the utility may need to approve solar and batteries. Lafayette Consolidated Government Permitting Division handles permits in Lafayette; see the permit information above.
