Going solar in Louisiana
Louisiana’s sunny skies, mild winters, and above-average natural gas prices make it a natural fit for solar panels. Going solar in Louisiana reduces your carbon footprint and your reliance on the utility electric grid.
Factor in the federal solar tax credit, and Louisianans can cut the cost of solar by thousands of dollars, speeding up your payback period and increasing the value of your investment.

Cost
How much do solar panels cost in Louisiana?
Solar panels will save you a lot of money over time, but the upfront costs aren't cheap. The average Louisiana homeowner needs a 10.97 kW solar panel system to cover their electricity needs, which comes out to $27,683 before incentives. Prices range from $23,531 to $31,835, but after the federal tax credit, that drops by 30%.
Over 8,900 Louisiana homeowners have used EnergySage to receive and compare quotes for solar installations. You can expect to earn back your initial solar investment through electricity savings in about 13.17 years, while most systems last at least 25 years. You'll often see this number referenced as your solar payback period.
There are a few ways to finance your solar panel system so you don't have to provide all that money upfront.
Cash purchase: You'll own the system and pay for it upfront. This provides the best long-term savings.
Solar loan: Allows you to retain ownership of your system, while owing little to no money upfront. Solar loans aren't all created equal: If you have access to subsidized clean energy loans through local incentive programs, that's usually your best bet. A home equity loan or a personal loan are often your next best options – private solar loans typically come with higher interest rates or upfront fees.
Solar lease or power purchase agreement (PPA): A third-party company owns your system and either leases you the solar panels (solar lease) or allows you to purchase the electricity they generate (PPA). These generally provide the lowest savings and generate the most negative press about solar. If you choose this financing option, read the fine print: You can get trapped in them for longer than you'd like.

Incentives
What are the best solar rebates and incentives in Louisiana?
Incentives help bring solar's price tag down considerably in Louisiana. Here are the major ones to know about:
| Incentive | Average savings in Louisiana | Description |
|---|---|---|
Residential Clean Energy Tax Credit, formerly the federal investment tax credit (ITC) | $8,305 | Lowers your solar panel system's cost by 30% |
Louisiana solar property tax exemption | 0.55% of your system’s cost, annually on average | If you use solar energy as a source of power, you won't need to pay for the value your solar panels add to your property |
Is net metering available in Louisiana?
Louisiana doesn’t offer net metering, but if you connect your solar panel system to the grid, you can benefit from net billing. The catch is that the utility companies only offer partial credit for every kWh you send to the grid—you’re selling the electricity to them at a significant discount, compared to what they’ll charge you to buy that electricity back later.

Equipment
Equipment quality
Solar panels continue to get more efficient, meaning they produce more power per square foot. In 2025, the most popular solar panels can produce about 450 watts of electricity in full sunlight—you’ll want panels with at least that much power output to get the most out of your installation.
It’s also important to choose a solar inverter setup that works for your roof’s layout.
And if you plan to install a solar battery, pick one that can easily integrate with that inverter.
While premium equipment can result in sticker shock, it typically saves you more money in the in the long run: The highest-quality panels degrade at a slower rate and maintain more of their power output for longer, and the best warranty terms often guarantee up to 40 years of coverage in case you need repairs or replacements.
