Solar Panels in Louisiana (2026 Guide)

Q: How much do solar panels cost in Louisiana in 2026?

About $2.50–$3.10 per watt installed — roughly $15,000–$18,000 for a 6 kW system and $25,000–$31,000 for a 10 kW system, before incentives.

Q: Does Louisiana have net metering?

Louisiana has moved away from full retail net metering. New residential solar customers are generally credited at a lower avoided-cost rate rather than the full retail rate, which lengthens payback and makes self-consumption more important.

Q: Does Louisiana have a state solar tax credit?

No. Louisiana's generous state solar tax credit ended years ago. There is no active state income-tax credit for residential solar in 2026.

Q: Is solar worth it in Louisiana?

It can be, but the case is weaker than in top solar states. With limited incentives and reduced net-metering credits, payback is longer — so it depends heavily on your electricity usage, rate, and whether you add a battery.

We'll be straight with you: Louisiana is a tougher solar market than the hype suggests. The sun is good and install costs are reasonable, but state incentives are thin, net-metering credits have been reduced, and electricity here is relatively cheap — which means less to save. Solar can still pay off for the right home, but the numbers need a closer look than in states like New York or California.

How Much Do Solar Panels Cost in Louisiana?

Louisiana sits near the national average, around $2.50–$3.10 per watt before incentives:

6 kW system: ~$15,000–$18,000
8 kW system: ~$20,000–$25,000
10 kW system: ~$25,000–$31,000

See our 2026 cost breakdown for what goes into that price.

What drives your cost in Louisiana

Your quote depends on system size, roof type and condition, equipment tier, and whether you add storage. With cheaper grid power and lower export credits, sizing the system to match your own usage (rather than overbuilding to export) usually makes the most financial sense here.

Net Metering in Louisiana — What Changed

Louisiana used to offer full retail net metering, but the state moved away from it. New residential solar customers are now generally credited for exported power at a lower avoided-cost rate rather than the full retail rate. Practically, that means the power you use yourself is worth much more than the power you export — so right-sizing your system, shifting usage to daytime, and considering a battery matter more than they would under full retail net metering.

Major Louisiana Utilities

The largest utility is Entergy Louisiana, alongside Cleco, SWEPCO (northwest LA), and several co-ops and municipal systems. Net-metering and interconnection terms are set under state rules and can vary by utility, so confirm the current export-credit rate for your specific provider before you buy.

Louisiana Solar Incentives in 2026

No state tax credit

Louisiana once had one of the most generous state solar tax credits in the country, but it ended years ago. There is no active state income-tax credit for residential solar in 2026 — be cautious of any installer or old article implying otherwise.

Limited local programs

Incentives are sparse. A few utilities or parishes may offer minor programs, and standard interconnection applies, but there's no broad state rebate to count on. Verify anything specific before assuming it's available.

No federal residential credit in 2026

The 30% federal residential credit expired December 31, 2025. A federal benefit still flows through leases and PPAs (commercial 48E). See our 2026 incentives guide.

Is Solar Worth It in Louisiana?

Honestly — it depends, and more so here than in top solar states. With limited incentives, reduced export credits, and relatively cheap grid power, payback periods run longer (often 12+ years for cash purchases). Solar makes the most sense in Louisiana if you have high electricity usage (big summer cooling load), a good south-facing roof, and you plan to stay in the home long-term — and especially if you self-consume most of your production. If those don't describe you, the math may not work yet. A custom quote will tell you honestly. See also Is Solar Worth It in 2026?
