Your Solar Strategy in Louisiana
Figuring out the best way to go solar in Louisiana can be a little daunting. From loans and leases to power-purchase agreements, there are a lot of options out there. To help you pick the one that might be best, we've created the handy decision tool below.
We'll ask you a few simple questions about you and your home. Once you're done, we'll recommend a good option. Further down this page, we provide cost estimates and example return-on-investment calculations for all the various options:
How to pay for solar panels in Louisiana
The chart above shows the 25-year returns for an investment in solar whether you choose to purchase a system with cash or pay over time with a loan. Before you scroll down, we'll get right to the point: unless you're willing to sink thousands of dollars into solar with little hope of a finacnial return, Louisiana is not a good place to invest in panels for your home.
Read more below about each of three options for solar in Louisiana.
How much can solar panels on roof save you?
Option 1: Paying cash for solar
Paying up front used to be the only way to get panels on your roof, and it's still the option that allows you the most control. But it isn't the best option from a percentage return on investment standpoint—that award goes to the solar loan option.
Still, an outright purchase means you own the system from day one and reap the benefits. You get the 30% Federal solar tax credit and electricity savings to bring your first-year costs way down. The trouble is, in Louisiana, these benefits are environmental; not financial.
In our example, you put down $20,000, but by the end of year 1, incentives and energy savings will erase a bunch of it. Over 25 years, your system will have produced more than $5,200 in income. But that late income makes the system not worth its cost, compared to an alternative investment. Check out the NPV:
Net Present Value: -$4,129
Net Present Value (NPV) measures how good of an investment something is, compared to the best alternative. We use a 6% return to evaluate all solar investments, and Louisiana's -$4,129 NPV on a 5-kW solar system means you'd be that much better off investing your money in stocks over 25 years than solar. Electricity is just so cheap in Louisiana right now, a solar system for you home isn't a good investment unless the environmental benefits are worth at least $4,129 to you.
Here’s how the numbers work for a Louisiana solar purchase of a 5-kW rooftop solar system:
- Installing a typical 5-kW solar system should start at about $20,000.
- The Feds calculate their 30% tax credit based on actual out of pocket costs, so you'll get $6,000 back as a tax credit, for a new price (after year 1) of $14,000. Note: you can take the credit over as many years as necessary if you don't owe $6,000 in Federal taxes this year.
- Next, you'll subtract your first-year energy savings, which will add up to about $544, bringing your cost after the first year to $13,456. Those savings will continue for the life of your system, and will only get bigger over time, considering that utility companies raise their rates 3.5% annually on average.
- By the time your system pays itself back in year 20, you’ll be seeing over $900 per year in savings until the end of your 25-year warranty.
- When all is said and done, our estimate shows a total net profit of $5,261, with an internal rate of return of 2.5%. That's not even half as good as a 25-year investment in the stock market, which means solar isn't the best investment option—but it is a way to make a little money while doing good for the environment.
- On top of those returns, your home's value just increased by just about $14,000, too (your expected annual electricity savings over 20 years)!
- And speaking of doing good for the environment... your system will create some green for the earth by not using electricity from fossil-fuels. In fact, the energy you’re not using has the carbon equivalent of planting 101 trees a year, every year your solar power system is humming.

Option 2: Using a loan to pay for solar
Usually, this is where we tell you that taking a loan for solar panels is a no-brainer, because it means investing in an income-generating asset. And technically, that's true in Louisiana, too. It's just not a sure-thing like it is in other states, because Louisiana has some of the lowest electricity prices in the nation, and the savings aren't as great.
As you can see from the chart above, you'll start out with a big windfall, because with a loan, you're not putting any money down, and you get the Federal 30% tax credit for the whole installed cost of your system. Then, over the 15-year repayment term of your loan, you'll be spending more than you're saving in electricity costs, to the tune of about $1,000 per year until you pay the loan off.
After that, you'll save over $800 per year in electricity costs from your paid-for solar panels, but by the end of the system's 25-year warranty, you still won't have broken even. That means a solar investment like this in Louisiana will cost rather than save you money over the long term.
Net Present Value: -$2,503
Net Present Value (NPV) measures how good of an investment something is, compared to the best alternative. We use a 6% return to evaluate all solar investments, and Louisiana's -$2,503 NPV on a solar loan means you'd be that much better off investing your money in stocks over 25 years than solar. We believe in the environmental benefits of solar, but $2,503 is a lot of money to pay for something that usually saves you money over the long term.
Here’s how the numbers pencil out for a Louisiana solar purchase with a solar loan:
- Installing a typical 5-kW solar system should start at about $20,000. That's how big your loan will need to be to cover it.
- The electricity you'll save in the first year of operation would have cost $544, but your loan payments will total $1,775, for a difference of $1,231, or about $102 per month.
- That's not so bad when you consider your tax savings for the year will be $6,000! You'll come out nearly $4,800 ahead in year 1, which should help ease the burden of loan payments for a few years, at least.
- When your loan’s paid off after year 15, you’ll start see over $800 year in savings until the end of your system’s life.
- Still, at the end of your 25-year panel warranty, you'll be in the hole about $1,400. That's not a huge amount of money, but considering what you could have made from an alternative investment, it ain't pretty.
- If you decide the cost is worth it, the environmental benefits might make you smile a little. Operating your system will take as much carbon out of the air as planting 101 trees every year!

Option 3: Buying the electricity, not the panels with a Power Purchase Agreement (PPA)
Louisiana does not offer solar Power Purchase Agreements or leases. Perhaps it would be a good idea to contact a solar advocacy organization and ask them to fight for solar in your state!

Louisiana Solar Policy Information
Ever wonder why solar seems to be everywhere in some states, but not in others? We did too.
State legislatures and public utilities commissions can enact rules to make solar power accessible for everyone. Favorable rules explain why some of the cloudiest states—New York, New Jersey, and Connecticut, are doing so well with solar, and yet some of those with the most natural solar resources—like Alabama, Mississippi, and Georgia—are doing so poorly.
Below is important information about the public policy, rules, and economic reasons that affect your ability to go solar here in Louisiana:
Louisiana's Renewable Portfolio Standard
A Renewables Portfolio Standard (“RPS”) requires utilities in the state to eventually source at least a certain percentage of their electricity from clean, renewable sources like solar panels. Typically you can tell how strong a state’s solar incentives are just by looking at the RPS. A strong RPS means strong rebates and other cash incentives. A weak, or worse, no RPS at all generally means little to no incentives for solar power. Fortunately that’s not the case here, thanks to that tax credit we’ll get to in a second. But even still, a strong RPS could help shift some of the cost of incentivizing solar power to the utility companies that are still chugging along on fossil-fuel based power.
An RPS is critical to strong renewable energy policy. Utility companies aren't really all that gung-ho about you producing your own power. After all, it costs them money when you use less of their electricity. They also don’t naturally want to give you big payments for energy you're feeding back into the grid. The main reason the utilities are aiding the transition to lower electric bills and offering incentives to put solar on roofs is because the state forces them to. Without an RPS, Louisiana is missing opportunities to help homeowners take advantage of clean, reliable solar power.
Even without a strong RPS, there is still good reason to go solar in LA. Read on to find out why.
Louisiana's Solar carve-out and SRECs
The best states for solar mandate that a certain percentage of the RPS comes directly from solar energy. Without a mandatory RPS in Louisiana, this is another area that falls short. If an RPS contains specific carve-outs for clean and efficient technologies like solar panels, or mandates for the environmentally necessary increases in distributed generation, you see even stronger incentives for residential solar power.
Louisiana Electricity Prices
Louisiana pays just 9 cents per kWh for electricity—the cheapest rate in the nation. Cheap electricity rates mean you’re probably not feeling too much of a strain in your pocketbook... yet. Just don’t forget why electricity is so cheap.
Most of our electricity still comes from burning millions of tons of fossil fuels. The cost of those fossil fuels in dollars and cents may be low (for now), but the environmental costs are astronomically high. New regulations on carbon emissions and dwindling supplies will likely drive the cost up over the next few decades. But while everyone else is paying through the nose for the fuels of the past, you’ll be rocking that sweet, shiny solar power system on your roof, and making money! Just remember to thank us.
Louisiana Net Metering
Buy-all sell-all wholesal
Unfortunately for homeowners in Louisiana, state lawmakers decided to completely gut the net metering policy which existed in the state. Granted, the rules before were kind of a joke with arbitrary caps on credits issued, and 50% credit for any non-used kilowatt hours of home solar electricity. Until the legislature gets this figured out, the state is not ideal for new home solar.
Louisiana Interconnection Rules
Louisiana’s net metering law includes basic interconnection requirements, but does not establish any set any actual interconnection rules beyond those basic safety compliance requirements. As a result, there is no standard interconnection process here. The net metering law does not address insurance requirements. Sadly the law does require a redundant external disconnect switch, though many inverter-based systems (as yours almost certainly will be) can qualify for an exemption if other safety shutdown features are in place.
Louisiana Solar Incentives
Next to high electricity prices and net metering, solar incentives have traditionally been the most important factor for whether home solar power makes financial sense in a state. In the past, some states with otherwise lousy policy had tremendous incentives that drove down the up-front cost of going solar so much that homeowners could save oodles of money even without net metering or a good RPS.
These days, the big incentive most people can get is the Federal Solar Tax Credit that earns you 26% of your total system costs back after just 1 year. State incentives play less of a role than in the past, but some really good ones are still out there, ready to help homeowners go solar and save money before you know it.
Let's see how Louisiana measures up:
The availability of state solar incentives for residential solar systems was sourced from the Database of State Incentives for Renewables and Efficiency, utility company websites, and the state public utility commission.
Louisiana Solar Power Rebates
Like we said, this is where you really see the effect of having no RPS here. Without mandatory minimum levels of renewable energy, the utility companies are happy to keep relying on all those fossil fuels so long as the profits keep coming in. If they have no incentives to encourage solar power, the utilities aren’t very motivated to give you any incentives either. That’s why there are no performance payments or utility rebates available here.
Louisiana Solar Tax Credits
This is where Louisiana used to shine, but no longer. The state once offered huge solar income tax credits that cut people a CHECK for any portion over their tax bill. It made going solar here a really good idea, but the gravy train has been parked in the garage, disassembled, and sold for scrap. No more tax credits mean Louisiana's solar industry is all but dead.
Property Tax Exemption
Louisiana also offers tax exemptions to help make solar power more attractive. You are 100% exempt from all property taxes associated with the increase in home value caused by installing a solar power system. And there is an increase. That’s going to save you a pretty nice chunk of change every year.
Sales Tax Exemption
Unfortunately, there is no sales tax exemption here, meaning you’ll pay an extra 4% up front on the cost of your system.

The consensus on Louisiana solar power rebates and incentives
Louisiana is a state run by fossil fuel interests. They finally succeeded in killing home solar power for all but the most stalwart environmentalists who can afford to take a financial hit for their love of the natural world we currently enjoy. The state gets an F this year, and we don’t expect that to change any time soon. It’s a sad commentary on the ability of business and government to work in collusion to stiff ordinary folks who’d just like to be financially and environmentally smart.
