Is Solar Worth It in Connecticut?

If you live in Connecticut, you already know your electric bill is one of the biggest checks you write each month. The question is whether solar actually lowers it, or just adds another payment. Here's a clear answer, the numbers behind it and the homes where it doesn't fit.

Is solar worth it in Connecticut?

Yes, for most homes with a good roof. A roof that gets steady sun, has room for panels and has years of life left is the starting point. If yours does, three things work in your favor.

• Electricity is expensive here. Every kilowatt-hour your panels make is one you don't buy from the utility at Connecticut prices.
• RRES sets your solar compensation for 20 years. Your rate is locked by the year your application is received.
• You can start with $0 down. With a loan, lease or power purchase agreement (PPA), a solar payment usually comes in below the electric bill it replaces from the first month.

That's the short version. Our guide to what solar costs and saves covers the basics for all of New England. This article goes deeper on Connecticut.

Why are Connecticut electric bills so high?

A big share of your bill has nothing to do with the electricity you use. When we broke down a sample Connecticut bill, about 70% of it was fees and charges rather than the power itself:

• Public benefits, 29%. State-mandated programs, such as low-income support and relief for unpaid bills.
• Local delivery, 29%. The poles, wires and equipment that bring power from the main line to your home.
• Transmission, 11%. Moving power across the high-voltage grid.

Solar can't change those charges, but it changes how much power you buy. When your panels cover much of your use, you buy far fewer kilowatt-hours from Eversource or United Illuminating. Our Connecticut solar incentives page walks through the full sample bill.

Rates also tend to climb over time. A solar payment that stays the same while the utility's price goes up is the main reason the savings grow year after year.

How does RRES pay Connecticut solar owners?

RRES (Residential Renewable Energy Solutions) is how Connecticut pays new home solar systems. It's open to Eversource and United Illuminating customers, and you pick one of two options when you enroll. Under the Public Utilities Regulatory Authority's 2026 decision, the terms are the same in both territories:

• Buy-All. The utility buys every kilowatt-hour your system produces at $0.3289 per kWh for applications received in 2026, locked for 20 years. You keep buying power for your home as usual, and the payment arrives as bill credits.
• Netting. Your panels power your home first, and every extra kilowatt-hour you send to the grid earns a bill credit at your retail rate. For 2026 enrollments, Netting systems also pay a production charge of $0.0402 per kWh. It's a charge, not a bonus.

PURA set the rates so both options give a similar return. The choice can't be changed later, and it stays with the house if you sell. Our article on RRES Netting vs. Buy-All explains which one fits which home.

How much does solar save in Connecticut?

Our Connecticut customers save about $1,285 a year on average. Across Evergreen Solar customers, savings average about 15% on day one, which means the solar payment plus the small utility bill that remains comes in lower than what you pay the utility today.

That first-month gap is only the start. Your solar payment stays predictable, while the price of utility power tends to rise. Each year, the bill you avoid gets bigger, so your savings grow without you doing anything.

You'll still get a small bill from the utility. It covers fixed customer charges and the power you draw at night and in winter beyond what your system covers. In summer your panels often make more than you use, and under Netting those extra credits help cover the darker months. Our guide to how net metering works explains how bill credits show up.

Before you commit, our Day One Savings Guarantee checks the numbers. We compare your solar quote with your average electric bill, and if the quote isn't lower, we'll contact you and offer to cancel your consultation, so nobody's time is wasted. It covers solar-only projects, and it compares the quote with your bill rather than guaranteeing production.

What are the ways to pay for solar in Connecticut?

Evergreen Solar offers five ways to pay, and three of them start with $0 down. The right one depends on whether you want to own the system and which incentives you want to use.

• Lease or PPA. You pay a fixed monthly amount (lease) or a set rate for the power your panels produce (PPA). Because the system qualifies for the 30% federal credit, you get a lower rate, which is often a better deal than buying. The company that owns the system handles maintenance.
• Solar loan. You own the system with $0 or little down and a fixed monthly payment, and you choose your RRES option as the owner. Connecticut's Smart-E loan, from the Connecticut Green Bank through local lenders, lends up to $50,000 and lists standard rates from 6.99% to 7.99% depending on the term, as of October 2026. Up to 25% of it can go to related work such as roof repairs before solar. Our guide to solar loans in Massachusetts and Connecticut compares it with private loans.
• Prepaid PPA. One payment up front covers the system's expected power, so there's no monthly solar bill.
• Cash. You own the system outright with no loan payments.

If you're paying cash or using a loan, note that the federal homeowner tax credit ended for systems installed after December 31, 2025. Owners now rely on RRES and their bill savings instead, and many find a lease or PPA comes out ahead.

Some Connecticut homes sit in federal energy communities, where a leased or PPA system can qualify for a larger federal credit. Under the Treasury list released June 10, 2026, those include all of New Haven and Windham counties, plus certain census tracts in Fairfield and New London counties. Our energy community guide shows how to check your address. For leases and PPAs, timing matters too: systems that begin construction after July 4, 2026 must be in service by December 31, 2027.

When is solar not worth it in Connecticut?

Solar isn't right for every house. It's a weaker fit in a few cases:

• Heavy shade. A roof shaded by tall trees for most of the day can't produce enough to beat your bill.
• Very low usage. If your bill is already small, there's less for solar to replace.
• A roof near the end of its life. Putting panels on a worn roof means paying to remove and reinstall them when it's replaced.

That last one has an answer. Our solar + roof program includes a new roof with your solar installation at a genuinely reduced price, and the total package often still costs less than your current electric bill. Roofs installed through the program carry a 50-year warranty.

The quickest way to know for your home is to check your roof and compare every way to pay on the same design. You can also call us at (508) 507-2908.
