The term "solar incentives" generally refers to financial incentives implemented by the government and by solar companies to encourage the use of renewable energy by making installing and using solar panels more affordable. Incentives can include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered federally, while others are handled by the state of Connecticut or by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Net Metering: You can sign a net metering agreement with your Greenwich utility company, that may apply to all or a percentage of the excess electricity your solar panels generate. They will then subtract this value from your utility bill each month.
  • Rebates: Solar rebates can be offered by your county or state, or by your local utility company. These rebates work as partial refunds that are applied after your purchase of a solar system and before tax credits are calculated.
  • Tax Exemptions: These may come in the form of property tax exemptions, which can let you ignore the value added by your solar panels when calculating the taxes you pay on your house. They may also include exemptions on sales tax at the time of purchase.
  • Tax Credits: Tax credits lower, dollar-for-dollar, the total amount of tax you owe the federal government. Tax credits differ from tax deductions.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some familiarity with. The Federal Solar Investment Tax Credit, or ITC, is likely the most commonly known federal solar incentive. The ITC offers a tax credit for a predetermined percentage of your solar system's cost.

The ITC is applied to the total cost of solar system installation, including the panels themselves as well as labor, equipment and accessories. 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. The tax credit ranges from 26-30% of total costs depending on when your project was completed. There is no maximum claim amount.

Talking to your local Greenwich solar panel installer is the best way to understand how the ITC could apply to you.

In August 2022, the ITC (now titled the Clean Energy Credit) was bolstered by the passage of the Inflation Reduction Act. Under the new program, solar installation projects started after January 1, 2022, and completed by the end of 2032, might qualify for a 30% tax credit. This credit amount will then decrease slightly each year until the current Clean Energy Credit expires in 2035. Starting in 2023, the expansion to the program will also make it easier to get credit for energy storage systems.

More information about the new Inflation Reduction Act can be found here. The best way to understand how the new Clean Energy Credit will apply to you is to speak with your local Greenwich solar panel installers directly.

State & Local Solar Incentives

There are more than just federal solar incentives; tax credits, rebates and more are often offered at the local or state level. Some incentives are ongoing, while others are available for a limited time. These incentives may be given by your county or municipality, or by the Connecticut government.

Next Steps for Installing Solar in Greenwich

Speaking with your local Greenwich solar panel installation expert is the best first step towards getting the most money possible when you switch to solar energy.

How do I learn if I qualify for different solar incentives?

It's best to speak with your local Greenwich solar installer for a better understanding of which incentives your project may qualify for.

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

You can decrease your carbon footprint by 200 pounds of CO2 a year by switching to solar panels. This adds up to approximately 4,000 pounds over 20 years. Solar is also a renewable energy source, which means that switching your home over reduces the drain on our planet's resources.

I want to trade in my old appliances for ones that are more energy-efficient. Are there any benefits I can claim?

The new Inflation Reduction Act introduces multiple incentives that reward homeowners who make eco-friendly upgrades. Some incentives include rebates and tax credits for installing new electric appliances. You can find more details about these incentives here.

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

Yes, you can receive both tax credits and rebates towards the cost of solar panels. Depending on which incentives you are receiving, they may apply in a different order. Make sure that you talk to your solar installer or a local tax professional to confirm that you are claiming the correct incentives and getting the most money possible.
