The term "solar incentives" refers broadly to financial incentives put in place by solar companies and the government to encourage increased use of renewable energy by making installing and using solar panels more affordable. Various types of incentives, such as cash back, discounts or credit towards your monthly utility bill, may be available to you. Some incentives may be handled by the state of Pennsylvania, by your utility company or by county or municipality, while others are federal. Some solar incentives you might qualify for are:

  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. Counties or states will also offer limited-time rebates at various times. The value of a rebate will usually be deducted from your total price before tax credits are calculated.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government. (This is different from a tax deduction.)
  • Tax Exemptions: Sales tax exemptions go into effect at the time of purchase for your solar panels. Property tax exemptions let you exclude the added value of your solar system when you calculate how much property tax you need to pay.
  • Solar Renewable Energy Certificate (SREC): In general, solar systems that produce over a specific (generally small) amount of electricity will qualify for SRECs or other performance-based incentives. SRECs and the like are typically provided at the state level. You can sell SRECs to your utility company or another buyer, and this is usually considered part of your taxable income.
  • Net Metering: Net metering is an incentive you can get after your solar panels are up and running. If you've signed a net metering agreement with your King of Prussia utility company, the company will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some places, this credit is dollar-for-dollar, while in others you may be refunded a percentage of the value.

Federal Solar Incentives

Federal solar incentives are probably the first thing that you think of when thinking about solar incentives. The Federal Solar Investment Tax Credit, or ITC, is likely the most well-known federal solar incentive. The ITC provides a tax credit for a specific percentage of the cost of your solar system.

The ITC originally covered 30% of the total cost of solar system installation, and has fluctuated slightly over the last few years between 26-30%. The percentage you qualify for will depend on when your solar system was installed. The total installation cost includes the panels themselves as well as the cost of labor, equipment and accessories. There is no maximum claim amount. The ITC applies to solar panels installed after January 1, 2006, on your primary or secondary residence. The residence must be owned by you and in the United States.

Your local King of Prussia solar panel installation expert can provide more information about the ITC and how it might 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 Clean Energy Credit has increased the current credit up to 30% for solar systems installed between 2022 and 2032. At this point, the credit percentage will decrease slightly each year until the program expires in 2035. Starting in 2023, the expansion to the program will also make credits for energy storage systems even easier to claim.

More information about the new Inflation Reduction Act can be found here. The best way to understand how the new Clean Energy Credit might apply to you is to get in touch with your local King of Prussia solar panel installers.

State & Local Solar Incentives

Some solar incentives may be provided at the state and local level. Like with federal incentives, these could include rebates, tax credits and more. These incentives may be distributed by your county or municipality, or by the Pennsylvania government. Certain incentives are ongoing, while others are available for a limited time.
