Solar incentives mitigate the cost of installing a solar panel system on your home. This category of financial incentives is intended to encourage more Americans to convert their home partially or fully to renewable energy. Various types of incentives, such as cash back, discounts or monthly utility bill credits, might be available to you. Some incentives may be provided via the Tennessee government, by your utility company or by county or municipality, while other incentives are federal. You might qualify for any of the following types of solar incentives:

  • Net Metering: Net metering becomes relevant once your solar system is up and running. If you have a net metering agreement with your Knoxville utility company, they will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some areas, this is a dollar-for-dollar credit, while in others you may receive a refund equivalent to a percentage of the value.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund of your purchase, for your solar system. States or counties will also sometimes offer limited-time rebates. The value of a rebate will usually be deducted from your total price before any tax credits are calculated.
  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Tax Exemptions: These might come in the form of property tax exemptions, which would allow you to ignore the value of your solar system when paying property tax on your house. You may also qualify for an exemption on sales tax at the time of purchase.

Federal Solar Incentives

Federal solar incentives are likely the first thing that comes to mind when thinking about solar incentives. One of the incentives that most people are likely to be familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a predetermined percentage of your solar system's cost.

The ITC can be applied to solar systems installed after January 1, 2006, and allows you to deduct from your taxes a percentage of the total cost of solar panels, labor, equipment and accessories. This credit can apply towards 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 the amount you can claim may range between 26-30%. There is no maximum amount you can claim.

To better understand how the ITC will apply to your situation, reach out to your local Knoxville solar panel installer and request more information.

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, 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 this, the credit percentage will decrease slightly each year until the end of the program in 2035. The expansion also makes credits for energy storage systems even easier to claim, starting in 2023.

State & Local Solar Incentives

Some solar incentives are often also provided by state and local governments. As with federal incentives, these can include rebates, tax credits and more. Incentives might be offered by your county or municipality, or by the state of Tennessee. Some incentives might only be available for a limited time, while others are ongoing.

EcoWatch's Knoxville, TN Solar Incentives FAQs

How can I learn if I qualify for solar incentives?

In most cases, solar incentives apply to:

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

Specific incentives, including those run by the Tennessee government or by your county/municipality, may have additional qualifications. Talk to your local Knoxville solar installer to learn more about what incentives your project will qualify for.

I already have solar panels. Does my system qualify for any incentives?

You should plan to talk to a representative from the company that installed your system – or reach out to a local Knoxville solar installer — to clarify which incentives you might qualify for. If your solar panels were installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Solar systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

What are some environmental benefits of adding solar panels to my home?

You can reduce your carbon footprint by 100 pounds of CO2 a year when you install solar panels. This adds up to approximately 2,000 pounds in 20 years. Solar is also a renewable energy source, which means that switching your home over lessens the drain on our planet's resources.

I want to switch my appliances out for ones that are more energy-efficient. Are there any incentives I can apply for?

The new Inflation Reduction Act introduces multiple incentives meant 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 use a combination of multiple types of renewable energy to power my home?

Yes, you can utilize multiple types of renewable energy to power your home, such as a combination of solar and wind power. You can also combine renewable energy generation with a backup source of non-renewable energy. Make sure that you discuss the details of your plan with your local Knoxville solar panel installer, so that you understand what you'll need and what incentives you may or may not qualify for.
