The term "solar incentives" covers a wide range of financial incentives implemented to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. Solar incentives may include upfront discounts, cash back or monthly credits towards your utility bill. Some incentives are given by the federal government, some by the Virginia government and some by your specific utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Tax Exemptions: Tax exemptions may come in two forms. First, there is sales tax exemption, applied when you purchase solar panels. The second is property tax exemption. This allows you to ignore the value added by your solar system when paying property tax on your home.
  • Solar Renewable Energy Certificate (SREC): SRECs and other performance-based incentives may be available to you if your solar system produces over a specified (generally small) amount of electricity. These types of incentives are normally handled at the state level. You can sell the SRECs you receive to your utility company or other buyers, and the money you make is generally considered part of your taxable income.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in the amount of tax that you owe the federal government.
  • Rebates: A rebate is a partial refund after the purchase of your solar panels. These may be offered by your local utility company, your state or your county. The rebates are usually applied before calculating tax credits.
  • Net Metering: Net metering factors in after your solar panels are up and running. If you have in place a net metering agreement with your Fairfax utility company, it will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some locations, this credit is dollar-for-dollar, while in other places you might make back a percentage of the value.

Federal Solar Incentives

Federal solar incentives are likely the first thing that comes to mind when you think about solar incentives. The solar incentive that you're most likely to have heard of is the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a certain percentage of your solar system's cost.

The ITC can be applied to solar systems installed after January 1, 2006, on a primary or secondary residence in the United States that you own. Initially, the credit applied to 30% of the total cost – for panels, equipment, labor and accessories – although it may range from 26-30%, depending on the installation date of your solar system. There is no cap on the amount you can claim.

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

The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as renaming it to the Clean Energy Credit). The new Clean Energy Credit extends until 2035. You can now receive a 30% credit for solar systems that began installation after January 1, 2022, and are completed by the end of 2032. This new credit will then see a slight annual decrease until the date of expiration. The expansion also makes claiming credit for energy storage systems easier than ever before, starting in 2023.

State & Local Solar Incentives

Tax credits, rebates and more might be provided at multiple levels. On top of federal solar incentives, there are often state and local ones as well. These incentives might be provided by the Virginia government, or by your county or municipality. Some incentives may be ongoing, while others are available for a limited time.
