Eversource (Connecticut): how it credits the solar power you send to the grid
Retail credits with a Solar Energy Adjustment of about 4 cents per kWh for systems connected in 2026 (roughly 15% less). A replacement program must be finalized by April 2028.
Checked November 12, 2026. Utilities change these rules; check the current tariff before you sign.
How it works
Exported power earns roughly 85% of the retail price on average.
Connecticut's residential solar program lets you choose between netting, where exports offset usage, and selling all production to the utility.
The Solar Energy Adjustment trims the value of each exported kWh by about 4 cents.
A replacement program must be finalized by April 2028.
What it means for a typical Connecticut home
An average Connecticut home uses about 8,448 kWh a year. A 6 kW system costs about $15,420 at the 2026 median price and makes about 7,746 kWh in its first year, of which we assume about 4,648 kWh goes out to the grid because no one is home to use it.
| First-year savings | Payback | 25-year savings, after the price | |
|---|---|---|---|
| With Eversource (Connecticut)'s credit | $2,066 | 8 years | $48,026 |
| If every exported kWh earned the full price | $2,270 | 7 years | $54,560 |
The difference, about $6,534 over 25 years, is what Eversource (Connecticut)'s rules cost a typical system compared with full net metering. Using more of the power at home, while the sun is up, closes some of that gap. Uses Connecticut's average electricity price; Eversource (Connecticut)'s own prices may be higher or lower. Paid in cash, no federal credit, prices rising 2.5% a year, one inverter replacement.
