Solar incentives are meant to encourage people to switch their home over to renewable energy by offering financial incentives meant to lower the burden of solar panel installation and use. Incentives might include things like discounts, cash back or credit on your utility bill each month. Some incentives are offered federally, while others are provided by the Connecticut government or your specific utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Rebates: Rebates, or cash back after a purchase, are typically applied before any solar tax credits are calculated. Rebates may be offered by your local utility company, by your county or by your state.
  • Net Metering: Make sure you speak to your Portland utility company about signing a net metering agreement. This will allow you to receive credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, how much income tax you owe the federal government. These differ from tax deductions.
  • Tax Exemptions: Your solar system may qualify for both sales tax and property tax exemptions. Sales tax exemptions are applied at the time of purchase. Property tax exemptions allow you to ignore the value added by your solar panels when you are calculating property taxes on your home.

Federal Solar Incentives

When thinking about solar incentives, you likely think of federal incentives first. You might have heard of the Federal Solar Investment Tax Credit, or ITC. The ITC is a tax credit that reduces your taxes by a specified percentage of the money you spend installing solar panels.

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

To more fully understand how the ITC will apply to you, call your local Portland solar panel installation expert and request more information.

The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. Homeowners can now qualify for a credit of 30% of the total costs of solar system installation for projects started after January 1, 2022 and completed before the end of 2032. The percentage will then begin to decrease annually until the Clean Energy Credit expires in 2035. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

State & Local Solar Incentives

Some solar incentives may be provided at the state and local level. Like with federal incentives, these may include rebates, tax credits and more. Incentives may be provided by your county or municipality, or by the state of Connecticut. Certain incentives might only be available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Portland

You can receive solar incentives from the Connecticut government and the federal government, as well as from your local utility company. Growing availability of solar initiatives over the last 15 years has helped greatly increase nationwide adoption of solar energy. Your local Portland solar panel installation company can provide you with more details about which incentives you might qualify for, and get you feeling good about making the change to renewable energy today.

EcoWatch's Portland, CT Solar Incentives FAQs

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

Many solar incentives are intended to apply to a property you own that is located within the United States; most secondary residences will fall under this distinction. There may be other solar incentives available for commercial properties, depending on the specifics. We recommend getting in touch with your local solar installer and/or tax professional to fully understand what incentives may apply to your specific situation.

If I already have solar panels, can I still claim incentives?

If your solar system was installed after January 1, 2022, you may qualify for the newly increased 30% tax credit under the Inflation Reduction Act. If you installed your system between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the exact installation date. Speaking with the company that installed your system, or any local Portland solar installer, can help you learn more about what incentives you can apply for.

What are some of the environmental benefits of switching to solar energy?

You can decrease your carbon footprint by 200 pounds of CO2 annually when you install solar panels. This adds up to approximately 4,000 pounds in 20 years. In addition, solar power is a renewable energy source, meaning that switching your home over lessens the drain on our planet's resources.

If I switch my appliances out for ones that can use solar energy, are there any credits I can claim?

With the passage of the new Inflation Reduction Act, there are a number of new financial incentives for making eco-friendly improvements to your home. More details regarding these incentives, including information about incentives for purchasing new appliances, can be found here.

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

The order in which incentives are applied might vary depending on which incentives you receive but typically yes, you can receive multiple types of incentives for your solar project. Talk with your solar installer or a local tax professional to confirm you are claiming all the incentives you are eligible for and applying them in the correct order.
