The phrase "solar incentives" refers broadly to financial incentives implemented by the government and by solar companies to encourage the use of renewable energy by making solar panels more affordable. These incentives may include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are given by the federal government, some by the state of Connecticut and some by your utility company, county or municipality. Some broad categories of solar incentives include:

  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Rebates: Solar rebates can be provided by your county or state, or by your local utility company. These rebates are essentially cash back that is applied after your purchase of a solar system and before tax credits are calculated.
  • Tax Exemptions: Your solar panel system may qualify for both sales tax and property tax exemptions. Sales tax exemptions are effective at the time of purchase. Property tax exemptions allow you to ignore the added value of the solar panels when calculating property taxes on your home.
  • Net Metering: Be sure to speak with your Danbury utility company about signing a net metering agreement. This allows you to get a credit towards your utility bill every month for the value of excess energy your solar panels generate. You may receive either a dollar-for-dollar credit or 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 may be most familiar with is the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a percentage of the cost of your solar system.

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, equipment, labor and accessories. This credit can apply towards solar panels installed on a primary or secondary residence that you own in the United States. Originally, you could claim 30% of the total cost, although depending on when the project was completed, your credit may range from 26-30%. There is no maximum claim amount.

Reaching out to your local Danbury solar panel installation expert is the best way to understand how the ITC may apply to you.

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. The Clean Energy Credit re-raises the credit up to 30% for solar systems installed between 2022 and 2032. After 2032, the percentage will be reduced slightly each year until the end of the program in 2035. Starting in 2023, the program expansion will also make claiming credit for energy storage systems easier than ever before.

More information about the new Inflation Reduction Act can be found here. Your local Danbury solar panel company can answer any questions you have and explain how the new Clean Energy Credit applies to you.

State & Local Solar Incentives

Rebates, tax credits and more might be claimed at multiple levels. Along with federal solar incentives, there are often state and local ones as well. Some incentives are offered for only a limited time, while others are ongoing. Your local solar incentives might come from your county or municipality, or from the Connecticut government.

Next Steps for Installing Solar in Danbury

Nationwide solar energy use has increased enormously in the last 15 years, in part due to the increase in availability of solar incentives. You can obtain these incentives from your local utility company, the federal government or the Connecticut government. We recommend talking to your local Danbury solar installation company to learn more about these incentives and to be sure that you're getting the largest number possible for your solar panels.

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

Solar energy is a renewable energy source — by changing where you get your energy, you help reduce the strain on our planet's resources. A solar system can also reduce the CO2 emissions from your home by 200 pounds a year, or around 4,000 pounds over 20 years.

Can I receive incentives both towards the up-front cost of solar panels, and later as reimbursement?

Yes, you can receive both rebates and tax credits towards the cost of solar panels. Depending on precisely which incentives you are eligible for, they may apply in a different order. Be sure to talk to your solar installer or a local tax professional to verify that you are claiming incentives correctly and that you're getting the most money possible.

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 geothermal and solar. You can also combine renewable energy generation with a non-renewable backup source of energy. You should discuss your proposed plan with your local Danbury solar installation expert, to make sure you know what you'll need and what incentives you might or might not qualify for.
