The south gets more sun than most of the rest of the US, but some states along the Gulf Coast aren’t doing everything they could to take advantage of this nearly limitless resource. 

Among the states we’re covering here — Texas, Oklahoma, Louisiana, Arkansas, Tennessee, Alabama, Mississippi and Kentucky — some are experiencing a solar boom, while others actually try to restrict its spread. 

Jill Kysor, senior attorney with the Southern Environmental Law Center, said that increasingly key policies are being put in place to enable more solar in the south. 

“It’s a pretty direct relationship: If there’s net metering available, solar adoption rates tend to be pretty strong and if net metering is not available, it definitely has tended to lag.”

Even where there’s lag, there’s still plenty of solar potential to be found for those dogged enough to capture it.

Best national solar panel companies in the South

No matter how convincing reviews of solar companies are, you should always get multiple quotes before choosing one. These companies are the larger companies that CNET has put through its review process to good results. 

Local solar panel companies in the South

When it comes to available solar installers, the South is something of a hodge-podge, with some states well served and others, like Alabama and Mississippi, with just a handful of solar companies to select from.

How to determine which solar company in the South is best for me

Keep in mind that none of the above local companies, aside from NRG Clean Power, have gone through CNET’s review process. CNET’s reviews are based on our own research and industry knowledge; we do not directly test solar equipment or go through the ordering and installation process with any solar companies. 

When researching online, reviews like those from established organizations like the Better Business Bureau can sometimes be helpful. Keep an eye out for scams or overpromising salespeople.  

It’s imperative to do your own due diligence and research thoroughly before selecting a solar company, because each installation tends to be unique. Get multiple quotes from local installers before signing anything. Talk to friends and neighbors in your area about their experience with a solar installer. CNET has also broken down the solar scene in each state. You can find links to those articles above.

The cost of electricity

The cost of electricity in the South in June 2023 ranged from 11.243 cents per kilowatt-hour in Louisiana to 14.63 cents per kilowatt-hour in Alabama, according to the EIA. That’s slightly below the national average. In general, you’ll save more money quicker with solar if it’s replacing more expensive energy, but that’s also dependent on how much energy you use and the policies that support or deter solar adoption. 

Average cost of solar panels in the South

As of the first quarter of 2023, a finished solar installation was running $3.28 per watt on average nationwide, according to consulting firm Wood Mackenzie (PDF). The Lawrence Berkeley National Laboratory did its own analysis earlier this year and found the cost of a typical 8.6-kilowatt residential system was $31,558 to install before incentives, or about $3.67 per watt. Throughout the south, the cost of solar tends to run close to or below the national average, according to data from FindEnergy.com. A few exceptions are Louisiana, where the cost is above the national average, and Alabama, where state legislation disincentivizes solar installations and pricing data is hard to gather.

Solar panel incentives and rebates in the South

Overall, the south is lagging behind the rest of the country when it comes to solar incentives. According to Kysor, Alabama and its largest monopoly utility, Alabama Power, have some of the most punitive regulations in the country designed to discourage the spread of solar. That said, net metering policies and some incentives like property tax exemptions tied to solar systems, have slowly been put in place over the years and the region is catching up to the rest of the country slowly. 

Living in the South doesn’t exclude you from one of the most valuable incentives available: the US federal tax credit for solar. For any solar panels installed through the end of 2031, the federal government will credit you 30% of its cost on your income taxes.

How to pay for solar panels in the South

The process of paying for or financing a new solar system generally works the same in the South as anywhere else in the country. However, markets are influenced by the conditions set by local legislation, so you may find fewer financing options for solar in places where the policy climate is less favorable. 

Cash: Paying upfront is typically the quickest way to get your solar project moving forward, as with most things. It’s also a good way to keep more in your account by avoiding today’s high interest rates. 

Solar loan: There are a variety of financing products available designed specifically with solar systems in mind. They’re offered by both national and local financial institutions, so be sure to shop around for the best rates. A number of installers, particularly the larger national solar companies, may also have in-house programs to assist you, just ensure you read all the fine print. 

Other types of loans: All kinds of organizations are out there waiting to lend money for whatever reason. You can bring your own financing to many solar companies in the form of a personal loan, home equity loan or home equity line of credit, aka HELOC.

Lease or power purchase agreement: If a decades-long commitment isn’t your thing right now, ask about the possibility of leasing a solar system. Another popular arrangement is a power purchase agreement, that amounts to almost the same thing in practice, but with a different payment structure. Power purchase agreements availability varies state to state and location to location.

The solar potential of the South

The south may have a reputation for being cloudy compared to the desert southwest, but it still has some of the best solar potential in the country, especially in Texas. Some southern states, notably Alabama and Mississippi, have relatively high electricity prices, making solar potentially more attractive where policies like net metering are in place. 

Lots of solar panels and other equipment is currently manufactured in a few southern states, like Alabama.

“Without good solar policies, most of those panels are going to get shipped outside the state,” Kysor said. 

The region continues to lag behind with such policies, but Kysor is optimistic that nationwide incentives like the federal tax credit may provide needed momentum to change that.

Installation factors to keep in mind

Almost every home has solar potential, but there may be dealbreakers like a lack of line of sight to the east, south and west or other obstructions. Among the key things to consider as you begin to ponder going solar:

• Does your roof have life left in it? Be sure it’s got another 15-20 years remaining at minimum or consider reroofing before putting panels on top of it. 
• Check all local regulations and rules regarding solar, including state, municipal, county, neighborhood and homeowners’ associations. 
• Look into all available tax credits, favorable financing, net metering and other incentives that may make your solar dreams more attainable.
