Solar Panels in Louisiana (2026 Guide)

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

Roughly $2.50–$3.00 per watt installed — about $13,000–$16,000 for a 5 kW system and $25,000–$34,000 for a large 11–12 kW system, before incentives. Louisiana has few incentives, so that price is close to your final cost.

Q: Does Louisiana have a solar tax credit?

No. The state credit expired at the end of 2015 and was not renewed, and the 30% federal credit expired December 31, 2025. Solar buyers in 2026 don't get either.

Q: Does Louisiana have net metering?

Not full-retail net metering. Since 2020, utilities aren't required to offer it, and most credit excess power at avoided cost — about 3 cents/kWh. Using your own solar power, or storing it in a battery, is worth much more than exporting it.

Q: Is solar worth it in Louisiana?

For some homeowners — especially those with high bills, a good roof, and a right-sized or battery-paired system. With limited incentives, the payback is tighter than in other states, so run the numbers for your specific home.

Louisiana gets plenty of sun, but it's an honest "do the math first" state for solar. There's no state tax credit anymore, the federal credit ended for 2026 buyers, and utilities aren't required to offer full net metering. That doesn't mean solar can't pay off here — it means the numbers depend heavily on your usage, your roof, and how you finance the system.

How Much Do Solar Panels Cost in Louisiana?

In 2026, installed residential solar runs roughly $2.50–$3.00 per watt before incentives:

5 kW system: ~$13,000–$16,000
8 kW system: ~$20,000–$26,000
11–12 kW system: ~$25,000–$34,000

Because incentives are limited, the sticker price is close to what you actually pay — so getting competing quotes matters more here. See our 2026 cost breakdown.

Louisiana Solar Incentives in 2026

No federal tax credit for 2026 buyers

The 30% federal residential credit (Section 25D) expired December 31, 2025. The only remaining federal benefit reaches homeowners through leases and PPAs (48E through 2027).

No state solar tax credit

Louisiana once had a generous 50% state solar tax credit, but it expired at the end of 2015 and was never renewed. It does not exist in 2026 — be cautious of any installer or article that still mentions it.

Property tax exemption (this one helps)

Louisiana exempts the added home value from property tax, so going solar won't increase your property tax bill.

Energy-efficiency financing (HELP loan)

Louisiana's Home Energy Loan Program has historically offered low-interest loans for energy improvements. Terms change, so confirm current status. See our 2026 incentives guide.

Net Metering in Louisiana — Read This Before You Buy

The single most important factor here. Since 2020, utilities are no longer required to offer true (full-retail) net metering to new solar customers. Most plans credit exported power at the utility's "avoided cost" — around $0.03 per kWh, roughly a quarter of the retail rate. So power you use yourself is worth far more than power you export. The best-value systems are sized to match daytime usage and often paired with a battery. Always confirm the current buyback rate with your utility before signing.

Is Solar Worth It in Louisiana?

It can be — but it's case-by-case, not automatic. Solar tends to make sense if you have high electricity usage, plan to stay long-term, have a good sun-facing roof, and either buy a right-sized system or add a battery to get around weak export credits. Because Louisiana lacks payback-shortening incentives, a custom quote is the only way to know your real payback.
