Questions
The things people actually ask
What is the average electricity rate in Connecticut?
About 28 cents per kilowatt-hour all-in on Eversource and 29 cents on United Illuminating as of July 2026. Both utilities cut Standard Service supply rates on July 1, 2026 — Eversource by 8% and UI by 13% — but Connecticut remains among the most expensive states in the continental US, roughly 55% above the national average.
Is solar worth it in Connecticut?
At 28 to 29 cents a kilowatt-hour, yes for most well-oriented roofs. A kilowatt of panels produces roughly 1,168 kWh a year here, so a 9 kW system is worth about $2,943 annually before incentives. Connecticut also exempts solar equipment from sales tax and the added home value from property tax. The decision that matters most is Netting versus Buy-All under the RRES tariff, because it runs twenty years.
Does Connecticut have net metering?
Not in the traditional form. Connecticut replaced it with the Residential Renewable Energy Solutions tariff in 2022. You choose once between Netting, which credits exports against usage, and Buy-All, which sells all your production to the utility at a fixed rate. That choice locks for twenty years, so it is worth understanding your usage pattern before you make it.
Estimate what solar does against your Connecticut electric bill
Enter your bill and we’ll size the array that would cover it, and show the gross value of that production at your rate. It does not net off the customer charge, taxes or what you would still draw at night — for that, use the bill savings calculator. Nothing is sent anywhere; this runs in your browser.
An estimate from your own numbers, not a quote, and not a savings figure. It assumes 400 W panels, an 80% system derate and no roof constraints. Your real number depends on orientation, roof area and your utility’s export credit. Savings are not guaranteed.

What Connecticut homeowners pay
| Utility | All-in rate | Full breakdown |

The production side
What a roof in Connecticut produces
Connecticut averages about 4.0 peak sun hours a day. A well-oriented kilowatt of panels produces roughly 1,168 kilowatt-hours a year. A typical 9 kW residential system therefore produces around 10,512 kilowatt-hours annually, which at a rate near 28.0¢ is worth roughly $2,943 a year before any incentive.
Those are pre-shading figures. Trees, roof pitch and orientation move them, sometimes a lot, which is why we read your specific roof rather than quoting a state average at you.
What has actually moved
| Utility | Change | Effective |
|---|---|---|
| Eversource CT | −8% | July 1, 2026 — Standard Service supply, plus a May 1 public benefits credit |
| United Illuminating | −13% | July 1, 2026 — Standard Service supply |
| Connecticut all-in | 28–29¢ | Still among the highest in the continental US after the decrease |
Connecticut rates fell this summer. That is worth saying plainly, because most of the Northeast went the other way. A typical 700 kWh bill dropped about $38 a month on Eversource and $50 on UI. Even after that, 28–29¢ all-in is roughly 55% above the national average.
What Connecticut actually offers a homeowner
Connecticut replaced net metering with the Residential Renewable Energy Solutions tariff — a 20-year arrangement where you choose Buy-All or Netting once, at the start. A full sales tax exemption on residential solar equipment and a property tax exemption on the added home value. Energy Storage Solutions provides upfront and performance-based incentives for batteries. The federal residential credit ended for systems placed in service after December 31, 2025.
How export credit works in Connecticut
Under RRES you pick one of two structures and it runs twenty years. Netting credits your exports against your usage, closer to traditional net metering. Buy-All sells every kilowatt-hour you produce to the utility at a fixed rate and you buy back what you use. Which is better depends on your usage pattern — how to choose between Netting and Buy-All.
How Connecticut works
Why the number is what it is
Connecticut resets Standard Service twice a year, on 1 January and 1 July. The pattern is consistent: January goes up, July comes down.
Rates fell in July 2026 — Eversource about 8%, United Illuminating about 13%. The January 2026 reset had raised Eversource supply about 29%. Connecticut still has among the highest electricity costs in the continental United States.
The honest cost picture
Two ways to pay for solar
If you buy the system you own the equipment, keep any renewable credits, and carry maintenance. If you use a PPA it is $0 upfront — we install and own the system, you buy the power it produces, and you only pay for what it actually generates.
The residential federal tax credit (25D) ended for property placed in service after December 31, 2025.
You will still see ads promising a 30% credit that “ends December 31.” Read the date on them. What remains applies to the owner of the system — which, under a PPA, is us. SolarAmerica does not provide tax advice; talk to your tax professional.
