Solar incentives are designed to make renewable energy usage more affordable via financial incentives for individuals who install solar panels on their homes. The incentives could include upfront discounts, cash back or monthly credits towards your utility bill. Some incentives are provided by the federal government, some by the South Carolina government and some by your specific utility company, county or municipality. Some broad categories of solar incentives include:

  • Tax Credits: Different from tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.
  • Tax Exemptions: Your solar panels could qualify for exemptions on both sales and property tax. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions allow you to ignore the added value of the solar panels when you are calculating property taxes on your house.
  • Rebates: A rebate is a partial refund given after you've purchased your solar panels. These may be offered by your local utility company, your state or your county. The cash back that you get from the rebates is normally applied before calculating tax credits.
  • Net Metering: Be sure to speak to your Summerville utility company about signing a net metering contract. This will allow you to receive credit towards your utility bill every month for the value of excess energy generated by your solar panels. You might receive either a dollar-for-dollar credit or a percentage of the value.

Federal Solar Incentives

When thinking about solar incentives, federal incentives might be the first thing that comes to mind. The Federal Solar Investment Tax Credit, or ITC, is probably the most well-known federal solar incentive. The ITC provides you with a tax credit for a specific percentage of the cost of your solar system.

The ITC applies to the total cost of installing a solar system, including the panels themselves as well as equipment, labor and accessories. This credit can be claimed for panels installed after January 1, 2006, on a primary or secondary residence that you own, as long as it is located in the United States. The tax credit ranges from 26-30% of total costs depending on when your project was completed. There is no maximum amount you can claim.

To better understand how the ITC may apply to your situation, reach out to your local Summerville solar panel installation expert and request more information.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now titled the Clean Energy Credit. The new Clean Energy Credit now runs until 2035. Homeowners are now eligible for a 30% credit for solar systems that began installation after January 1, 2022, and are completed by the end of 2032. The credit will then decrease annually until it expires. The program expansion also makes credits for energy storage systems even easier to claim, starting in 2023.

State & Local Solar Incentives

Federal solar incentives are not your only option; tax credits, rebates and more are often offered at the state and local level.

What are some of the environmental benefits of switching to solar?

You can lower your carbon footprint by 100 pounds of CO2 annually by installing solar panels. This adds up to roughly 2,000 pounds over 20 years. In addition, solar power is a renewable energy source, meaning that switching your home over reduces the drain on our planet's resources.

When does the federal solar tax credit end?

The federal solar tax credit, previously called the ITC and now titled the Clean Energy Credit, is slated to end on January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.
