The term "solar incentives" refers broadly to financial incentives designed to encourage the adoption and use renewable energy by making installing and using solar panels more affordable. Different kinds of incentives, including discounts, cash back or credit towards your monthly utility bill, may be available to you. Some incentives may be offered by the state of South Carolina, by your utility company or by county or municipality, while others are federal. Types of solar incentives might include:

  • Tax Credits: Unlike tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government.
  • Rebates: Rebates, or cash back after a purchase, are usually given prior to any solar tax credits being calculated. These rebates may be given by your local utility company, by your state or by your county.
  • Tax Exemptions: These may come in the form of property tax exemptions, which can let you exclude the value of your solar system when paying taxes on your house. They may also include exemptions on sales tax at the time of purchase.
  • Net Metering: Net metering is an incentive you can get once your solar system is up and running. If you have a net metering agreement with your Union utility company, they will subtract the value of the excess energy produced by your solar system from your utility bill each month. In some areas, this credit is dollar-for-dollar, while in other places you may be refunded a percentage of the value.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some knowledge of. One of the incentives that most people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specified percentage of the cost of your solar system.

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

Your local Union solar panel installation expert can give you more information about the ITC and how it applies to your situation.

In August 2022, the Inflation Reduction Act made revisions to the ITC, now titled the Clean Energy Credit. The new Clean Energy Credit is valid until 2035. You are now eligible for a 30% credit for solar systems installed between 2022 and 2032. This credit will then see a slight annual decrease until its expiration. Starting in 2023, it will also be easier to claim credits for energy storage systems with the new act.

State & Local Solar Incentives

Some solar incentives may be provided at the state and local level. Similar to federal incentives, these might include rebates, tax credits and more. These solar incentives — which might be handled by the state of South Carolina, or by your county or municipality — may be offered for only a limited time, or on an ongoing basis.

Next Steps for Installing Solar in Union

The large number of solar incentives available has contributed greatly to the increase in the nationwide adoption of solar energy over the past 15 years. You can get solar incentives from your local utility company, the South Carolina government or the federal government. We suggest talking to your local Union solar installation company for more information about these incentives and to make sure that you're getting the largest number possible for your solar system.

EcoWatch's Union, SC Solar Incentives FAQs

What if I want to add a solar system to a vacation home, rental property or commercial property? Do I still qualify for incentives?

Many solar incentives apply to a property located within the United States that you own, and most secondary residences will fall into this category. There may be other solar incentives available for commercial properties, depending on the details. We recommend talking to your local solar installer and/or tax professional to better understand what incentives will apply to your specific situation.

How can I learn if I qualify for certain solar incentives?

Typically, solar incentives apply to:

  1. a new solar panel system
  2. installed on property that you own
  3. within the U.S.
  4. between the dates specified by a particular incentive.

Specific incentives, including ones handled by the South Carolina government or by your county/municipality, may have additional qualifications. Get in touch with your local Union solar installer to learn more about what incentives your project may qualify for.

Can I use 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. Make sure you go over your ideas with your local Union solar installation expert. They can help you plan your project and give you an understanding of various incentives that you might or might not qualify for.
