Are solar panels worth it in South Dakota?

Solar energy isn’t as popular in South Dakota as in other states, but going solar is often worth it for homeowners who want to save money and reduce their carbon footprint.

One solar customer we talked to, Adi in Brookings, put it this way: “You spend money on this, but overall you end up saving money in the long run. It is good for you and your family and it is also good for our environment.”

Financially, solar panels are only worth it in South Dakota — or anywhere else — if what you’re paying for the panels is cheaper than your current electric bill. The panels also have to keep working for it to pay off.

You spend money on this, but overall you end up saving money in the long run. ”
— Adi in Brookings

Some solar customers we’ve talked to are understandably frustrated when their equipment doesn’t work and their solar company won’t help them. If you run into a production issue and can’t resolve it quickly, you might end up paying more than you are now. Your solar loan payment is due whether or not the panels are working.

People who go solar with a trustworthy solar company, though, generally have much more positive feedback. On average, South Dakota homeowners with solar panels get an estimated net savings of $22,923 over 25 years.

Cost factors of going solar in South Dakota

In South Dakota, as in other states, the cost of your solar energy system depends on the quality of panels you install, additional equipment and permits. Here's a breakdown of what to expect.

Size of your system

Your system's size is another major factor in how much you pay overall. The higher your typical energy usage, the bigger the solar energy system you’ll need to generate enough power for your household.

You can easily determine what size system you need. First, find out the amount of electricity you used in the last year in kilowatt-hours (kWh). You can find this information through your electric bill’s online account dashboard.

Then divide your annual kWh by 1,200 to find the system size you need. For example, the typical South Dakota household uses 12,228 kWh per year. Using this formula, the typical household would need a 10-kW system.


Solar equipment costs

Equipment prices vary due to the quality of the equipment, the size of your system and the company you buy it from. In South Dakota, the average cost per watt to install a solar power system works out to $2.39.

The other big expense to consider is storage batteries. Sometimes they cost almost as much or more than the panels themselves. Here are some typical costs for batteries and other equipment:

Condition of your roof

Quality solar panels last around 25 to 30 years. To make sure your roof can handle the load, have your roof inspected and repaired before installing solar. Otherwise, you may have to pay to remove the panels, fix your roof and reinstall the panels again if you need to make repairs later.

Local permits and fees

Most towns have their own set of rules regarding permits required for solar energy system installation, and these permits can contribute to your total costs. The good news is that South Dakota passed a bill to streamline permit procedures for solar energy facilities and help the state’s Public Utilities Commission (PUC) manage its docket.

If you're residing outside city limits, you might not need permits, but it's always best to check before planning your installation. Some solar companies handle your permit-related tasks, so don't forget to ask about this service when you're ready to sign your contract — it could save you a lot of hassle.

Solar incentives, tax credits and rebates in South Dakota

The federal solar investment tax credit (ITC) is the biggest factor in reducing the cost of going solar in South Dakota. The average ITC value in South Dakota is $7,528 in 2023.

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. The credit drops to 26% in 2033 and 22% in 2034. South Dakota also offers a property tax exemption that can save you thousands of dollars.

  • Is there a down payment?
  • How much will I pay per month?
  • Will monthly payments increase, and by how much?
  • Will there be a lien on my house?
