Louisiana is one of the most expensive states to get solar panels. Before using any tax credits, a typical residential system costs $32,126 (about $10,000 more than the national average). That price drops to $22,488 after using the full federal solar investment tax credit (ITC).

Louisiana also offers a property tax exemption for the value a solar energy system adds to your home, and there are low-interest solar loans through the Louisiana Department of Natural Resources.

Key insights

  • You can take advantage of solar tax breaks and loan programs in Louisiana.
  • The average federal tax credit value is $9,638 in Louisiana.
  • Louisiana residents who go solar receive an estimated average net savings of $13,646 over 25 years.

Solar incentives in Louisiana

The federal solar investment tax credit (ITC) is the biggest factor in reducing the cost of going solar in Louisiana. If you install a residential solar panel system by the end of 2032, you will receive a federal income tax credit equal to 30% of the system's total cost — including equipment, labor and permits.

ITC drops to 26% in 2033 and 22% in 2034.

For example, the average system in Louisiana costs $32,126. At this price, you can get a $9,638 credit when you file your taxes.

The solar tax credit is not a rebate or refund — you must claim it when you file federal taxes in the year that your solar panel system becomes operational. To do this, you have to complete Form 5695. The credit is also nonrefundable, so any unused portion rolls over into the next tax year.

Statewide residential solar incentives in Louisiana

Louisiana has two solar incentives for residents wanting to go solar. The property tax exemption includes solar panels and other solar equipment. The other is a way to finance energy efficiency improvements through a partially subsidized loan program.

Property tax exemption

Homeowners get a 100% property tax exemption on any value solar investments add to their properties. This means there’s no increase in property taxes if their property value increases after installing solar panels.

It’s an ad valorem tax exemption, which means “according to value” in Latin. The exemption applies to solar panels, solar water heaters, solar space heaters and solar pool heating.

Home Energy Loan Program (HELP)

Homeowners can get loans of up to $12,000 to pay for solar panels, solar water heaters, solar space heaters and geothermal heat pumps.

The Louisiana Department of Natural Resources (LDNR) funds half the loan amount. The LDNR portion of the loan has a fixed 2% interest rate. The other half of the loan is subject to the market interest rate set by the lender. The overall interest rate is calculated as a blend of the LDNR’s 2% rate and the market rate on the other half.

Each lender sets its own maximum loan amount and interest rate, so terms vary. The program is designed to give borrowers lower interest rates than they could otherwise get. Unfortunately, the number of participating lenders is limited.

What to know about net metering in Louisiana

If you don’t store the excess energy that your solar system produces, you have the option of selling it to your electric company. This is called net metering. The electric company gives customers credits on their power bill as compensation for the power. If the credits aren’t used, the customer can exchange them for money when they discontinue their electric service.

Louisiana models its net metering after Arkansas’ policy. It requires utility companies to offer net metering to residents who generate electricity with solar, wind and other natural resources. Residential systems up to 25 kilowatts (kW) in capacity qualify. Commercial and agricultural systems can be up to 300 kW.

How can I pay for solar panels?

You can pay cash, but most people finance solar panels with a solar loan. It works a lot like any other type of loan — there’s an application and approval process, and you pay it back over time (with interest). Two other options are a lease or power purchase agreement.
