The phrase "solar incentives" includes 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. Incentives may include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered federally, while others are handled by the Connecticut government or your utility company, county or municipality. Some broad categories of solar incentives include:

  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Tax Exemptions: Tax exemptions can 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 exclude the added value of your solar system when paying property tax on your home.
  • Net Metering: Don't forget to speak to your Stamford utility company about signing a net metering contract. This allows you to get a credit towards your utility bill every month for the value of excess energy your solar panels generate. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: Solar rebates might be offered by your state or county, or by your local utility company. These rebates work as partial refunds that are applied after you purchase a solar system and before tax credits are calculated.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have some knowledge of. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. This incentive is a tax credit equal to a specified percentage of the money you spend on your solar system.

The ITC is applied to the total cost of solar panel installation, including the panels themselves as well as labor, accessories and equipment. This credit can be claimed for panels installed after January 1, 2006 on a primary or secondary residence that you own and that is located in the United States. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum amount you can claim.

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

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as renaming it to the Clean Energy Credit). The new Clean Energy Credit now runs until 2035. Homeowners can now receive a 30% credit for solar systems installed between 2022 and 2032. This credit will then be decreased by a few percentage points every year until it expires. The expansion to the program also makes it easier to get credit for energy storage systems, beginning in 2023.

State & Local Solar Incentives

There are often state solar incentives available in addition to federal ones. Rebates, tax credits and more can be offered at a more local level. Some incentives are ongoing, while others are offered for only a limited time. These local incentives could come from your county or municipality, or from the Connecticut government.

Next Steps for Installing Solar in Stamford

You can qualify for solar incentives from the Connecticut government and the federal government, as well as from your local utility company. This increase in availability of solar initiatives over the last 15 years has helped greatly increase nationwide adoption of solar energy. Your local Stamford solar panel installation company can give you more information about which incentives you should apply for, and get you feeling good about making the change to renewable energy today.

EcoWatch's Stamford, CT Solar Incentives FAQs

Can I claim incentives for adding solar panels to a rental property, vacation home or commercial property?

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

If my house already has solar panels, can I still claim incentives?

If your solar system was installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If you had your system installed between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the year it was installed. Speaking with the company that installed your solar system, or any local Stamford solar installer, can help you learn what incentives you qualify for.

How much can I save on my electric bill annually if I add solar panels to my house in Stamford?

On average, homeowners in Stamford who install solar panels save approximately $1,207.35 per year, or approximately $22,939.62 over 20 years after they make the switch.

How long until the federal solar tax credit ends?

The Clean Energy Credit (previously called the federal solar tax credit, or the ITC), is slated to end on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

Can I use a combination of 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 talk through your ideas with your local Stamford solar installer. They can help you plan your project and also help you understand the various incentives that you may or may not qualify for.
