Solar incentives mitigate the cost of installing a solar panel system on your home. Financial incentives like these are intended to encourage more Americans to make the switch to renewable energy. Incentives might include things like discounts, cash back or monthly utility bill credits. Some incentives are provided by the federal government, while others are handled by the state of South Carolina or by your specific utility company, county or municipality. Categories of solar incentives include:

  • Net Metering: Net metering is an incentive you can get after your solar system is up and running. If you have a net metering agreement with your Irmo utility company, it will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some areas, this credit is dollar-for-dollar, while in other areas you might receive a refund equivalent to a percentage of the value.
  • Tax Exemptions: Sales tax exemptions are effective at the point of sale for your solar system. Property tax exemptions allow you to ignore the added value of your solar system when you calculate how much property tax you need to pay on your house.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, how much income tax you owe the government. These differ from tax deductions.
  • Rebates: Solar rebates can be offered by your local utility company, or by your county or state. These rebates work as cash back that is applied after you pay for a solar system and before tax credits are calculated.

Federal Solar Incentives

When thinking about solar incentives, you likely think of federal incentives first. An incentive that most people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a given percentage of the cost of your solar system.

The ITC covers solar systems installed after January 1, 2006, and allows you to deduct from your taxes a percentage of the total cost of solar panels, equipment, accessories and labor. This credit can be claimed on solar panels installed on a primary or secondary residence that you own in the United States. The original claim amount was 30% of the total cost, although certain projects may qualify for only 26%, depending on the details. There is no maximum claim amount.

Speaking with your local Irmo solar panel installation expert is the best way to learn more about how the ITC may apply to your situation.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as retitling it the Clean Energy Credit). The new Clean Energy Credit is valid until 2035. Homeowners are now eligible for a 30% credit for solar systems that began installation on or after January 1, 2022, and will be done by December 31, 2032. This credit will then be decreased by a few percentage points every year until its expiration. Starting in 2023, it will also be easier to claim credits for energy storage systems under the new laws.

State & Local Solar Incentives

Some solar incentives are often also provided at the state and local level. Like with federal incentives, these might include tax credits, rebates and more. Certain incentives are ongoing, while others are offered for only a limited time. Your local solar incentives might come from the South Carolina government, or from your specific county or municipality.

EcoWatch's Irmo, SC Solar Incentives FAQs

How do I know if I qualify for specific solar incentives?

It's best to speak with your local Irmo solar installer to get an understanding of which incentives your project will qualify for. In most cases, solar incentives apply to new solar panel systems installed on a property you own (in the U.S.) within a specified date range. Some incentives, such as those given by the state of South Carolina, might have other requirements.

What are the environmental benefits of switching to solar?

You can lower your carbon footprint by 50 pounds of CO2 annually by installing solar panels. This adds up to around 1,000 pounds over 20 years. Solar is also a renewable energy source, meaning that switching your home over reduces the drain on our planet's resources.

If I trade in my appliances for ones that utilize solar energy, are there incentives I can claim?

The new Inflation Reduction Act introduces multiple incentives designed to reward homeowners who make eco-friendly upgrades. Some of these incentives include tax credits and rebates for installing new electric appliances. You can find more details about these incentives here.

Can I receive incentives both towards the initial cost of solar panels, and later as reimbursement?

Yes, you can receive both rebates and tax credits towards the cost of solar panels. Depending on which incentives you are eligible for, they may apply in a different order. Be sure to talk to your solar installer or a local tax professional to ensure that you are claiming incentives correctly and that you're getting the most money possible.

Can I use a combination of multiple types of renewable energy to power my home?

You can power your home with multiple types of renewable energy, or a combination of renewable and non-renewable energy. Be sure to discuss your ideas with your local Irmo solar installer. They can help you as you plan for your project and educate you on the various incentives that you will or won't qualify for.
