As of February 2024, the average solar panel system costs $3.17/W including installation in Connecticut. For a 5 kW installation, this comes out to about $15,863 before incentives, though prices range from $13,484 to $18,242. After the federal tax credit, the average price drops by 30%.

You'll probably pay even less than what we show here. It doesn't include the federal ITC or Connecticut state incentives, which will lower this price by at least a few thousand dollars.

Your solar panel cost depends on your system's size

It may seem obvious but larger solar panel systems cost more money. We use cost per watt ($/W) so you can easily compare quotes, controlling for slight variations in system size.

While a 5 kW system will only cost you $15,863 in Connecticut, doubling the system size effectively doubles the price, so you'll pay about twice that for a 10 kW system. The higher the price tag, though, the more you'll get back as a credit towards your federal tax bill.

6 kW$19,036$13,325
7 kW$22,208$15,546
8 kW$25,381$17,767
9 kW$28,553$19,987
10 kW$31,726$22,208

Are solar panels worth it in Connecticut?

Solar panels are worth it in most areas, including Connecticut. Certain factors, including the cost of electricity, incentives, climate, and the angle at which the sun hits your roof impact how quickly you break even on your investment relative to other areas around the U.S. 

If you pay for your system with cash, you'll save about $68,664 over 20 years on electricity costs with a 5 kW system in Connecticut. We generate this estimate based on real solar quote data from our Marketplace. It considers your system's cost, the federal tax credit, and inflation rates.

If you don't have access to net metering, these estimates don't account for utility net billing rates.

If you can't shell out $15,863 in cash to pay for solar, don't sweat it. You can choose to finance your system with a loan instead. Some companies even offer $0-down loans so you can start saving on day one if your loan payments are less than your current electric bills. Just keep in mind that your long-term savings will be lower with a loan due to interest rates.

Solar is a major purchase, but you can get the price tag to come down a bit by being an educated shopper. Taking advantage of incentives and rebates and shopping around for quotes can bring down your cost of solar in Connecticut.

Take advantage of federal and local solar incentives

As long as your federal tax bill is high enough, you can take advantage of the federal tax credit in Connecticut. This incentive allows you to apply 30% of your solar installation and equipment costs toward your federal tax bill. If the amount exceeds your tax bill, you can roll over the remaining credit to the following year. Many states also offer great local incentives and rebates.

Get quotes from multiple installers

Comparing multiple solar quotes can save you money through competition and transparency. Each additional quote you receive for solar will help you find the right solar panel system at the right price.

This is where EnergySage can help. With funding from the Department of Energy’s SunShot Prize, EnergySage opened the country’s first (and now the largest) marketplace for home solar panel installations. We gather custom solar quotes from local installers on your behalf and put them in an easy-to-compare format. When you compare quotes for solar panels on the EnergySage Marketplace, you can expect to see prices up to 20% lower than if you work with a single solar company.
