Cost of Solar Panels in Louisiana

The cost of solar panel systems in Louisiana is around $2.57 per watt, which is below the national average of $2.66. However, Louisianans use a lot more energy than residents in most states to combat the hot, muggy summers and cold winters. Most Louisiana homeowners need a system that is around 12.5 kW to offset their electricity costs.

This is a larger system size than the national average. As a result, all-in costs in Louisiana are higher overall despite a lower per-watt price and relatively low electricity rates, even in busy cities like New Orleans and Baton Rouge.

What Determines the Cost of Solar Panels in Louisiana?

If you’re looking to install solar panels on your home in Louisiana, you can expect to pay anywhere from $19,018 to $30,429 on average after the federal tax credit. 

There’s over an $11,000 range in typical pricing because your system cost depends on a few factors that can bring your price up or down by thousands. We’ll discuss these cost factors below.

Solar Equipment

The brand of solar panel you choose is among the most significant cost factors to consider. There are many brands to choose from, and some brands can be twice as expensive as others. 

It’s important to choose a brand that suits your budget and can also satisfy your energy needs, as they range in their level of efficiency as well.

Louisiana residents experience around 214 sunny days per year, which is above the national average. With the abundant sunlight in the area, most major solar brands, regardless of efficiency, will be suitable. 

This means that most homeowners can opt for more affordable, less efficient brands without sacrificing much in the way of power production. Overall, this equates to a slightly lower overall price for panels statewide.

The type of equipment you install can also bring your price up by thousands or more. Unfortunately, Louisianians often need to add solar batteries to their systems to stay protected against prolonged and often dangerous power outages caused by the severe weather of the region.

A fragile infrastructure combined with hurricanes, tornadoes, cyclones and intense thunderstorms can all cause hazardous blackouts, so many homeowners end up paying more for systems that can provide energy, and safety, through an outage.

Solar Financing in Louisiana

How you’ll pay for your solar panels is another key consideration that can decide where in the normal range your system price falls. 

  • Paying with cash means you’ll spend the least amount possible on your system over time, although this option is prohibitively expensive upfront for many people. 
  • Choosing a solar loan is far more accessible, but it means your total system cost will increase because of the interest you’ll pay.

Louisiana does offer several affordable solar loan options available to homeowners. One such program is the Property-Assessed Clean Energy (PACE) program, which provides low-APR loans for solar equipment to minimize interest payments. 

Low-income households in Louisiana can also take advantage of the Home Energy Loan Program (HELP), which provides up to $12,000 in funding with low interest rates and little or no money down for qualifying homeowners. 

Additionally, the New Orleans Solar for All initiative offers accessible loan and lease options to those who cannot secure financing. 

Louisiana Solar Installation Company

The company you hire to install your panels can have an impact on your pricing as well, sometimes in ways you might not expect.

Much like you’d see in any other industry, every solar installer can customize their pricing with equipment upcharges, discounts and variances in labor charges. Every company’s pricing will be different, even when installing the same equipment.

What you might not expect is that the quality of equipment in a company’s product portfolio can also affect your system price. 

For example, Solar Alternatives, a regional provider and one of the top solar companies in Lousiana, installs equipment from many manufacturers, including Tesla, Silfab, SMA, Enphase and Mission Solar Energy. These products run from very affordable to very expensive, but since it offers a wide variety of options, the average price of its services will be on the more affordable end relative to its larger competitors.

SunPower, a national solar company serving Louisiana, only installs Maxeon panels. Its panels are considered some of the best in the industry, but they’re also the most expensive. 

Without offering budget-friendly options like Silfab and Mission, the average price of SunPower systems is much higher than a company like Solar Alternatives. 

Additional Considerations and Costs in Louisiana

Some additional things you might want to consider prior to installing solar panels are explained briefly below

  • Permits: The State of Louisiana requires building (and sometimes electrical) permits for all solar panel systems. You should confirm with your installer if it will be pulling the permits and closing them out or if that responsibility will fall on you as the homeowner. In most municipalities, your installer will handle the permit.
  • Interconnection: All solar installations in Louisiana must be cleared with the local utility before they can be powered on. In most cases, this will be with Entergy. Think about this as getting a permit from your electrical company. You’ll also need to pass an inspection. Entergy, the largest electricity provider in the state, charges a one-time fee of $100 for interconnecting. 
  • Warranties: Solar panel systems usually come with warranties — both from your installer and manufacturer. You should understand yours fully and choose the best one that fits your budget. Solar panels are costly, and a warranty can help provide peace of mind and guaranteed performance — especially in a state with severe weather like Louisiana.
  • HOAs: Louisiana passed solar rights laws in 2010, so no homeowners’ association (HOA) or other entity can prohibit you from installing panels. Most homeowners, regardless of HOA status, should have no issues.
  • Environmental zoning: The zoning laws in Louisiana are generally supportive of solar installations. However, you might run into some issues if you’re looking to install ground-mounted panels, as flood risk will come into play.

Louisiana Solar Incentives

Paying upfront or financing a photovoltaic system in Louisiana might seem overwhelming from a cost perspective, but there are a number of incentives available to Louisiana residents that make switching to clean energy more accessible. We’ll discuss the solar rebates and incentives available in Louisiana below.

Federal Solar Tax Credit For Louisiana Homeowners

The most significant tax credit you’ll receive for Louisiana solar panels is offered by the federal government in the form of the federal solar investment tax credit (ITC). This rebate is for a massive 26% of your entire costs for switching to a renewable energy source, which, in Louisiana, averages out to $8,353.

The federal tax credit will drop to 22% in 2023, at which point the average rebate in LA will be $7,068. The credit is set to expire in 2024 unless Congress renews the bill.

Net Metering Policies in Louisiana

Net metering is a policy that compensates you for any excess energy your solar array produces. Through interconnection, your home will receive power from the grid if your panels ever fail to produce enough energy to meet your home’s needs — like at night or on a cloudy day. If your panels produce more than your home is using — like on a sunny day — then your home is powered off-grid, the excess gets routed to the electric provider and your meter runs backward.

Unfortunately, net metering in Louisiana is not required by state law, so not every utility company offers it to consumers. Those that do often have a lower rate of compensation than the price you pay for energy coming in. Every utility company has a different policy and buyback rate, so it’s best to check yours before committing to a net metering program.

For example, Energy Louisiana, a company that serves an enormous part of the state, changed its net metering policy in 2020 due to new regulations. The change saw a lowered buyback rate from retail prices to wholesale prices or what it calls an “avoided cost rate.” Ultimately, policies like this lower the overall value of solar power in Louisiana, but converting to solar is still considered a good investment for most homeowners.

Local Solar Rebates in Louisiana

First, and most importantly, is the solar property tax exemption. Installing rooftop solar on your home, provided you buy the system outright or finance it, will increase your property value. Usually, increases in property value also bump up your tax assessed value and property taxes. The property tax exemption promises that your taxes won’t go up from the value added to your home when you go solar. For many customers, this can mean thousands of dollars in savings.

Second, the Department of Natural Resources in Louisiana has established the Home Energy Loan Program (HELP). This program provides access to low-APR financing options for home improvements that increase energy efficiency, including solar conversions, up to $12,000. The program further lowers the barrier to entry and makes solar more accessible to homeowners throughout Louisiana.
