What Solar Incentives and Rebates Are Available in Louisiana?
Going solar in Louisiana can cost less than you think — if you know which incentives to use. Between federal tax credits, state-level programs, and utility rebates, many Louisiana homeowners can cut thousands of dollars off the price of a residential solar installation. This guide breaks down what's available, how each program works, and what to watch out for.
The Federal Solar Tax Credit (ITC): The Biggest Savings Available
The most valuable incentive for any Louisiana homeowner going solar is the federal Investment Tax Credit, or ITC. As of 2025, this credit allows you to deduct 30% of your total solar installation cost from your federal income taxes.
For example, if your system costs $20,000, you could claim a $6,000 credit on your federal return. This is a dollar-for-dollar reduction in what you owe — not just a deduction.
Key things to know:
- You must own your system (not lease it) to claim the credit.
- If the credit exceeds your tax liability for the year, you can carry the remainder forward to future tax years.
- The 30% rate is locked in through 2032, then steps down in following years.

Louisiana State Solar Incentives: What's Still on the Table
Louisiana used to offer a strong state income tax credit for solar installations, but that program expired for most systems after 2021. As of now, there is no active Louisiana state income tax credit for new residential solar installations.
However, the state does offer one meaningful ongoing benefit:
Louisiana Solar Property Tax Exemption: Louisiana law exempts the added home value from a solar installation from your property tax assessment. In plain terms, even though solar panels can increase your home's market value, your property tax bill won't go up because of it. This is a real, ongoing financial benefit that lasts for the life of your system.
State programs can change, so confirm current rules with your installer or a local tax advisor.
Net Metering in Louisiana: Earn Credit for Extra Power
Net metering is a billing policy that lets you send unused solar electricity back to the grid in exchange for credits on your utility bill. When your panels produce more than you use — common on sunny Louisiana afternoons — those kilowatt-hours roll back your meter.
Louisiana requires investor-owned utilities to offer net metering to residential customers with systems up to 25 kilowatts. That covers the vast majority of home solar setups.
What this means practically: Your effective electricity cost drops significantly, and payback periods for your system get shorter. The exact credit rate varies by utility — Entergy Louisiana and CLECO customers should check with their specific provider for current net metering rates and caps.
Some utilities have enrollment caps on net metering programs, so it pays to act before limits are reached in your area.
Utility and Local Rebate Programs
Utility-level rebates in Louisiana are limited compared to some other states, but they do exist and change periodically. A few things to check:
- Entergy Louisiana: Has offered efficiency programs and may have solar-related incentives depending on your service area. Check their current program list directly.
- DEMCO and other co-ops: Some electric cooperatives in Louisiana have run their own solar or battery storage incentives. Terms vary widely by co-op.
- PACE Financing: Property Assessed Clean Energy financing is authorized in some Louisiana parishes, allowing homeowners to finance solar through a special property tax assessment. Not all parishes participate — confirm local availability.
Because utility programs change frequently, always ask your solar installer for the most current rebate opportunities in your ZIP code before signing a contract.
How to Stack Incentives and Maximize Your Savings
Smart Louisiana homeowners don't just pick one incentive — they layer them. Here's a simple approach:
- Start with the 30% federal ITC — this is the foundation of your savings.
- Confirm net metering enrollment with your utility before installation.
- Verify the property tax exemption applies in your parish.
- Ask your installer about any current utility rebates specific to your service territory.
- Explore PACE or other local financing if upfront cost is a barrier.
Getting multiple quotes from licensed Louisiana solar installers is one of the best ways to make sure you're getting both competitive pricing and full access to available incentives.
Frequently Asked Questions
Does Louisiana have a state solar tax credit?
The Louisiana state income tax credit for solar installations expired after 2021 and is no longer available for new systems as of 2025. The main state benefit now is the property tax exemption on added home value from solar.
How long does it take to get the federal solar tax credit?
You claim the federal ITC when you file your annual income tax return for the year the system is placed in service. There's no separate application — your tax preparer or software will include IRS Form 5695. If you can't use the full credit in one year, you carry forward the unused amount.
Will solar increase my property taxes in Louisiana?
No. Louisiana's solar property tax exemption means the added value of your solar system is excluded from your property assessment. Your property taxes should not increase as a result of installing solar panels.
What size solar system qualifies for net metering in Louisiana?
Residential systems up to 25 kilowatts are eligible for net metering under Louisiana's rules for investor-owned utilities. Most home solar systems fall well within this limit. Co-op and municipal utility rules may differ.
Is it better to buy or lease solar panels in Louisiana?
Owning your system outright — through cash purchase or a solar loan — lets you claim the 30% federal tax credit. Leasing typically means the leasing company takes the tax credit, not you. That said, leasing can reduce upfront costs. Compare total 25-year costs carefully before deciding.
Solar incentives move fast, and missing a rebate or filing deadline can cost you real money. If you're not sure which programs apply to your home or how to compare installer quotes, getting a second opinion is always a smart move.
