Best Solar Panel Installation Companies in South Dakota

South Dakota is no stranger to renewable energy. It was responsible for about 82% of electricity generated in South Dakota in 2021, with wind power supplying 52% and hydropower 30%. But when it comes to solar energy, the state receives less than 1% of its electricity from the sun; it's ranked second-lowest in the US for solar energy production, according to the Solar Energy Industries Association.

With very few solar incentives, cheaper electricity rates than many other states (11.29 cents per kilowatt-hour) and only 14 solar companies in the entire state, there aren't many reasons for South Dakotans to go solar.

South Dakota doesn't have a state net metering policy either, meaning any excess energy you sell back to the grid will typically be sold for less than the retail rate from the local utility company. You're able to get a property tax exemption on your solar panel system in The Mount Rushmore State, however, and all US residents are able to get a 30% rebate on the cost of their clean energy home alterations due to the federal solar tax credit.

How much money you'll save with solar depends on your location, energy usage, your roof's condition and other factors. Here's what you need to know if you're looking to go solar in South Dakota, starting with the best solar companies operating within the state.

Best national solar companies in South Dakota

You don't have too many solar company options to choose from in South Dakota. There are 14 solar companies in the state, and only six of them are solar installers or developers, according to data from SEIA.

Even though your options are limited, you should still get quotes from multiple solar installers for the best price possible. Make sure you also take customer reviews, solar panel maintenance fees and warranties into consideration when choosing your solar installer.

Here is one national solar company to consider based on our research and our rankings of the best solar companies nationwide.

Tesla Solar

Most affordable

Tesla's solar branch seems to be the least loved of Elon Musk's ventures. Even Tesla's Solar Roof seems to get more love.

If price is the thing you won't budge on, consider Tesla. By all accounts, Tesla installs quality panels and makes the closest thing there is to a household name in solar storage: the Powerwall.

Where you might miss out is customer service. Discussion online seems to suggest Tesla's service is a bit of a gamble.

Cost of solar panels in South Dakota

"The cost of solar has dropped significantly over the last decade, and it's now more affordable than it's ever been to install solar panels," Heidi Kolbeck-Urlacher, a policy manager with the Center for Rural Affairs, a rural and clean energy advocacy organization, told CNET.

The cost of solar panels depends on a wide variety of factors, so everyone's experience with pricing is usually a little different. The main factors affecting solar panel prices are your location, the size of your solar system, the type of solar panels installed and any add-ons you want, like a solar battery.

"A homeowner would want to take a look at calculating the amount of energy that they could produce from their solar panels and what their average electricity usage is. And also pricing out local costs from solar companies," Kolbeck-Urlacher said.

The solar industry in South Dakota is quite small, so state-level pricing on solar panels is tricky to gauge. However, Kolbeck-Urlacher said South Dakota solar prices have seen a significant decline over the past decade.

State solar data isn't readily accessible for South Dakota, but here's a look at the typical system size and prices nationwide, according to data from FindEnergy.com.

South Dakota solar panel incentives and rebates

Solar incentives can help relieve the financial burden of installing solar panels and encourage homeowners to invest in clean energy. The state only offers one state-level solar incentive: a property tax exemption.

South Dakotans who choose to install solar panels can also take advantage of the federal residential clean energy credit, which allows you to claim a 30% tax credit of the total cost of your home's solar system, assuming you meet the requirements.

Ask your solar installer for any other programs or incentives offered in your area.

South Dakota solar incentives

Program	Description
Residential clean energy credit	The residential clean energy credit offers 30% in tax credits of the total cost of your solar system. This credit will drop to 26% in 2033.
South Dakota property tax exemption	The state offers a local property tax exemption for renewable energy systems that are 5 megawatts in size or less. This continuous exemption applies to the exemption of real property tax on the first $50,000 or 70% (whichever is greater) of the assessed value of the solar system.
Rural Energy for America Program	This program is provided by the US Department of Agriculture, and offers guaranteed loan financing and grants to farmers and rural small businesses toward renewable energy systems.

How solar-friendly is your state?

CNET recently ranked states based on their residential solar policies: the laws and regulations affecting consumer-level solar panel installation and adoption. These policies play a major role in determining how accessible and affordable a solar panel system is to the average resident.

Each state was evaluated through a methodology and scored based on eight categories. The final score was converted to a letter grade.

Here's how your state scored on CNET's solar policy test.

South Dakota

Grade: F

Incentives available:

Solar panel systems exempt from 70% of property taxes (up to a cap of $50,000)

Strongest scoring categories:

South Dakota offers a large exemption on property taxes, helping tamp down costs over time by up to five figures. It's not a full exemption, but it will shave off the majority of the property taxes you have to pay.

Categories to improve:

A full exemption on property taxes would be a quick and easy way to improve state solar incentives. South Dakota is also missing any type of net metering program -- the state doesn't even have a solar buyback program offering an exchange at the wholesale rate. This is an absolutely crucial incentive, and it would be the best place to start building out more state incentives.

How to pay for solar panels in South Dakota

It's no secret that solar panels are expensive. With such a large investment, it's important to get a good grasp of your options. Here are a few ways to pay for your panels.

Cash: If you've got the money, paying for your solar panels upfront is likely your best option. There are no interest rates or high financing fees you'll need to worry about, and you'll always be eligible for tax incentives and rebates. If you're planning to go solar in the future, you could also consider putting money aside now in a high-yield savings account, which will net you more money over time.

Solar loan: Your solar provider will often offer financing options via a solar loan. These loans are usually through a third party, so keep an eye on the fees and interest rates associated with a solar loan.

Other loans: If you can't pay with cash, a solar loan isn't your only option. You can also take out a personal loan through your bank, or opt for a home equity line of credit (HELOC). Just be aware that if you go with a home equity loan or HELOC, your home becomes collateral -- and you could face foreclosure if you can't pay it back.

Lease or power purchase agreement: Leasing your solar panels means the solar company owns the solar system, and you pay for the use of the system. There's also the option of entering a power purchase agreement. This agreement means you'll pay for the electricity generated by a company's solar system at a fixed rate that is normally lower than the retail rate offered by your local utility company. Solar power purchase agreements are not available in some states. Ask your installer which options are available to you.

Installation factors to keep in mind

There are more factors to consider beyond the money to find out if solar is the right choice for you. Here are some things to think about:

The condition of your roof: Your roof should be in good condition before installing solar panels. Some roofs may not be suitable for solar due to age, damage, pitch or tree cover. Trustworthy solar installers will conduct a roof inspection before installation. The direction and pitch of your roof play an important role in the efficiency of your solar system. Solar panels perform best on south-facing roofs at an angle between 15 and 40 degrees.

Homeowners association regulations: Since solar panels impact the look of your home, some homeowners associations may not allow solar installation. Check with your HOA for rules and permissions before installing solar panels.

Insurance coverage: Check to see if your homeowner's insurance agency covers rooftop solar panels. If they do, consider including your solar panels on your insurance policy.

Your location: The longer the sun is at its peak, the more electricity your solar panels will generate. For such a cold climate, South Dakota is a surprisingly sunny state, getting an average of 5.23 peak hours of sunshine per day.

Rentals: Renters interested in solar don't have much authority over changes to the property they are renting. You might not be able to install solar panels, but you may be able to subscribe to a community solar program, which connects your home to power generated from nearby solar farms.
