Milford sits in United Illuminating territory on the Connecticut shoreline, so your solar is credited under the state RRES program, where you pick a Netting or a Buy-All tariff for 20 years. Connecticut power runs about 27 cents per kWh (EIA, May 2026), and a 6 kW roof here makes roughly 7,869 kWh a year (NREL PVWatts). Shoreline homes may also need coastal site plan review.
Milford is a New Haven County shoreline city of about 50,000 people, stretched along Long Island Sound from Silver Sands to the Housatonic River. For a homeowner the solar question is concrete: Connecticut has some of the priciest electricity in the country, a Milford roof makes real power, and the way that power gets paid for changed in 2022. This guide leads with the live production number for a Milford ZIP, then covers what Milford CT solar costs, how United Illuminating and Connecticut’s RRES program credit the electricity you send back, which incentives remain now that the federal homeowner credit has ended, and the coastal permitting details worth planning around before you sign anything.
Milford solar at a glance (2026)
According to MySolarFY’s analysis (August 2026), a 6 kW rooftop in Milford (ZIP 06460) should generate about 7,869 kWh in its first year, worth roughly $2,150 against Connecticut’s power at about 27.37 cents per kWh (production modeled with NREL PVWatts v8; rate from EIA, May 2026). Your actual output depends on roof pitch, orientation, and shading, and what you keep depends on the RRES tariff you choose, so treat this as a planning estimate and confirm your own numbers with a quote.
| Milford detail | What to know (2026) |
|---|---|
| Your electric utility | United Illuminating (UI), the delivery utility for Connecticut’s southwest shoreline including Milford (United Illuminating) |
| Electricity rate | Connecticut residential power averages about 27.37 cents per kWh (EIA, May 2026), among the highest in the nation |
| Estimated production | About 7,869 kWh per year for a 6 kW system at ZIP 06460 (NREL PVWatts v8) |
| How exports are paid | The statewide RRES program (Netting or Buy-All), which replaced retail net metering for new residential systems on January 1, 2022 |
| Permitting | Building and electrical permits through Milford’s Civic Access online portal; shoreline lots may also need coastal site plan review (City of Milford) |
| Federal tax credit | The 30% residential credit (Section 25D) ended for systems placed in service after December 31, 2025 (IRS) |
One thing to get straight first: your utility is United Illuminating, not Eversource. Inland Connecticut cities like Manchester and New Britain are Eversource towns, but Milford, along with Bridgeport, New Haven, West Haven, and Stratford, sits in UI’s coastal territory. The RRES tariff terms are the same statewide, but your interconnection, your bill, and your Permission to Operate all run through UI. For the utility-wide picture, see our guide to United Illuminating solar and the RRES tariffs.
Why solar pays in Milford
Connecticut’s power prices are the whole reason the math works. At about 27 cents per kWh, well above the national average near 18 cents, every kilowatt-hour a Milford roof makes offsets expensive grid power. Pair that with roughly 7,869 kWh a year from a typical 6 kW system, and the roof is displacing a meaningful chunk of a shoreline home’s bill. The catch is that Connecticut no longer pays you retail for everything you export, so the tariff you pick under RRES decides how much of that production actually lands on your bill. Estimate your own roof with the free PVWatts calculator, then have an installer model the RRES options for your usage.

United Illuminating RRES: Netting or Buy-All in Milford
Connecticut closed traditional net metering to new residential systems on January 1, 2022, and replaced it with the Residential Renewable Energy Solutions program, or RRES. Every new Milford system picks one of two tariffs, each locked for 20 years (United Illuminating RRES). For how these credits work in plain language, see our Connecticut net metering guide and the deeper netting vs buy-all math.
| RRES tariff (UI, 2026) | How you are paid | Worth knowing |
|---|---|---|
| Netting (net-metering style) | You use your own solar first, then any monthly net excess is credited at UI’s retail rate, supply and delivery included (UI RRES FAQ) | A Solar Energy Adjustment of $0.0402 per kWh applies to all your production for 2026 enrollees, and the separate REC rate is $0.000 |
| Buy-All | You sell all the power your panels make to UI at a fixed rate and buy your home’s power at the normal retail rate (UI RRES) | The 2026 Buy-All rate is $0.3289 per kWh, locked for 20 years; low-income and distressed-municipality adders can raise it |
Which one wins depends on how much of your own power you use. Netting tends to suit a home that consumes a lot of its solar on site, because self-used power offsets electricity at Connecticut’s high retail rate. Buy-All can suit a home that exports most of its production, because the fixed $0.3289 per kWh sell rate is locked for two decades even as retail rates reset about every six months (UI RRES FAQ). Ask your installer to model both paths for your specific usage before you commit, because the choice holds for 20 years.
Ask for 2026 numbers, not last year’s. The Solar Energy Adjustment rose for 2026 Netting enrollees and applies to all your production, not just exports. It does not sink solar against 27-cent power, but it changes the Netting-versus-Buy-All comparison, so make sure any quote uses current RRES figures and shows your estimated bill after solar.
Coastal permitting in Milford: what shoreline homes should plan for
Milford runs solar permits through its Civic Access online portal, and rooftop solar is a listed permit type. A residential install generally needs a building permit for the roof attachment and an electrical permit for the new circuits, inverters, and disconnects (City of Milford Plan Review and Permits). What makes Milford different from an inland CT town is the shoreline. If your property falls inside Connecticut’s coastal boundary, the project can trigger coastal site plan review through Milford Planning and Zoning under the state Coastal Management Act (City of Milford Coastal Site Plan Review).
Flood-zone rules add another layer near the water. Homes in a FEMA coastal flood zone such as VE or AE face elevation and documentation requirements, and Connecticut’s Public Act 18-82 requires certain structures in the 100-year coastal flood zone to be elevated two feet above the base flood elevation to account for sea level rise (CT DEEP Solar Permitting Factsheet). Rooftop solar by itself rarely triggers new elevation work, but if your install ties into a structure being rebuilt or substantially improved in the flood zone, plan for it. Verify your parcel’s zone and any coastal review with Milford’s Building and Planning and Zoning departments before you schedule work.
Connecticut incentives a Milford homeowner can stack
Beyond the RRES tariff, Connecticut adds two tax breaks and a battery program, and none of them depend on the federal credit that ended after December 31, 2025. One note up front: Connecticut does not offer a state income tax credit for residential solar, so do not expect one. For the full stack, see our Connecticut solar incentives guide, the Connecticut solar hub, and our general guide to solar incentives.
| Incentive | What it gives you | The Connecticut detail |
|---|---|---|
| Sales-tax exemption | Waives Connecticut sales tax on residential solar equipment | 100% of the state sales tax on qualifying systems (DSIRE) |
| Property-tax exemption | Excludes solar’s added value from your assessment | The added home value is exempt from local property tax (DSIRE) |
| Energy Storage Solutions | An upfront and performance incentive for home batteries | Statewide battery program; verify current incentive levels, which change by enrollment period (CT PURA) |
| Federal residential (Section 25D) | A 30% homeowner credit | Ended for systems placed in service after December 31, 2025 (IRS) |
Confirm before you count on it. Incentive levels and program rules change, so verify each figure with the linked source and ask a tax professional about your own situation. MySolarFY does not provide tax advice.
Frequently asked questions about Milford CT solar
Who is my electric utility in Milford, CT?
United Illuminating (UI). Milford is part of UI’s coastal service territory in New Haven County, so your interconnection, billing, and Permission to Operate run through UI, not Eversource.
How much power does a solar system make in Milford?
A 6 kW rooftop system at ZIP 06460 produces about 7,869 kWh in its first year, per NREL PVWatts v8. Your actual output depends on roof pitch, orientation, and shading.
Does Milford still have net metering?
Not the old retail version. Connecticut replaced it on January 1, 2022 with the RRES program, where you choose a Netting or a Buy-All tariff for 20 years. The 2026 Buy-All rate is $0.3289 per kWh.
Do I need a special permit for coastal solar in Milford?
Rooftop solar needs building and electrical permits through Milford’s Civic Access portal. If your property is inside Connecticut’s coastal boundary, the project may also require coastal site plan review, and flood-zone lots have elevation rules.
What happened to the 30% federal solar tax credit?
It ended. The Section 25D residential credit ended for systems placed in service after December 31, 2025, so most 2026 buyers cannot claim it. Connecticut’s own sales-tax and property-tax exemptions are separate from the federal credit and are not affected.
