Solar incentives encourage people to switch their home over to renewable energy by offering incentives that lower the financial burden of solar panel installation and use. Incentives can include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are provided by the federal government, while others are offered by the South Carolina government or by your utility company, county or municipality. Types of solar incentives might include:

  • Tax Exemptions: Your solar panel system may qualify for exemptions on both sales and property tax. Sales tax exemptions are effective at the time of purchase. Property tax exemptions let you exclude the value added by your solar panels when calculating property taxes on your home.
  • Rebates: Solar rebates might be provided by your county or state, or by your local utility company. These rebates work as partial refunds that are applied after your purchase of solar panels and before tax credits are calculated.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the federal government.
  • Net Metering: You can sign a net metering agreement with your North Charleston utility company that will apply to all or a percentage of the excess electricity your solar panels generate. Your utility company will then subtract this value from your monthly utility bill.

Federal Solar Incentives

When thinking about solar incentives, you probably think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is probably the best-known federal solar incentive. The ITC provides a tax credit for a set percentage of your solar system's cost.

The ITC was originally for 30% of the total cost of solar system installation, and has fluctuated slightly over time between 26-30%. The percentage you qualify for will depend on when your solar system was installed. The total cost of installation includes the panels themselves as well as the cost of equipment, labor and accessories. There is no maximum amount you can claim. The ITC can be applied to solar panels installed after January 1, 2006, on your primary or secondary residence. The residence must be in the United States and owned by you.

To best understand how the ITC will apply to your situation, call your local North Charleston solar panel installation expert and ask for more information.

The ITC was renewed and increased in scope after the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. The Clean Energy Credit has increased the current credit up to 30% for solar installation projects started after January 1, 2022, and completed by the end of 2032. After 2032, the credit percentage will be reduced slightly each year until the program expires in 2035. Starting in 2023, the program expansion will also make claiming credit for energy storage systems easier than ever before.

State & Local Solar Incentives

Rebates, tax credits and more can be claimed at multiple levels. Along with federal solar incentives, there are often state and local ones, too. These incentives may be handled by the South Carolina government, or by your county or municipality. Some incentives may be available for a limited time, while others are ongoing.
