After the full federal solar investment tax credit, the average system is $20,944 in South Carolina, which is more expensive than in many other states. The national average is $16,715. The overall cost may be high, but there are some local incentives to help you go solar for less.

Key insights

  • The average federal tax credit value is $8,976 in South Carolina.
  • You can also use rebates and loan programs to make solar more affordable.
  • South Carolina residents who go solar receive an estimated average net savings of $24,561 over 25 years.

Solar incentives in South Carolina

The federal solar investment tax credit (ITC) helps you save big when going solar in South Carolina. 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 federal solar ITC drops to 26% in 2033 and 22% in 2034.

For example, the average system in South Carolina is $29,920. You can get a $8,976 credit if you take advantage of the ITC when you file your taxes.

The important part is that you must claim the ITC 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, which means it rolls over to the next tax year if your credit exceeds your federal tax liability.

Residential solar incentives in South Carolina

South Carolina offers its residents many money-saving incentives for solar. You can get tax credits, property tax exemptions, rebates and loans.

Tax breaks 

There are two money-saving tax breaks available statewide in South Carolina:

  • Personal tax credit: You can receive a state income tax credit equal to 25% of the costs of a new solar system. This includes equipment and installation, though the credit is capped at $3,500 or 50% of your tax liability for that taxable year. What’s left after the cap can be carried forward for the next 10 years.
  • Property tax exemption: You can also get a property tax exemption for the value your solar energy system adds to your home. Your system must be 20 kilowatts (kW) or less to qualify.

Santee Cooper incentives 

Santee Cooper Electric has rebates and loans to make going solar more affordable for its customers.

  • Santee Cooper Electric solar rebates let you get up to $5,700 back on the cost of your home’s new solar system. The catch is the system must be installed by a qualified Santee Cooper Trade Ally or NABCEP-certified photovoltaic (PV) installation professional.
  • Santee Cooper solar loans are available in amounts ranging from $500 to $20,000. If you borrow more than $1,000, you have up to 60 months to pay it back. There's no down payment required.

What to know about net metering in South Carolina

When your solar panels produce more energy than you can use and you don't have a solar battery to store it, that extra power goes back to the electrical grid. That's when net metering kicks in. This program gives you credits on your electric bill for the energy you send back to the grid.

How much each credit is worth varies depending on the time of year and your current electric rate. The compensation is added to your next month’s bill as a credit. If you don’t use all your credits, your utility company will pay you whatever is left over at the end of the year.
