What Connecticut still offers after the federal credit ended
Every incentive on this page is verified against Connecticut government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Waterbury systems completed in 2026 get $0 from it.
Under Connecticut's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Waterbury homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.

Connecticut rules that decide your payback
| Rule | Connecticut status |
|---|---|
| Export compensation (net metering) | Connecticut ended net metering for new residential systems - anything interconnected on or after January 1, 2022 is compensated under PURA's Residential Renewable Energy Solutions (RRES) tariff for a 20-year term, with the homeowner choosing either the Buy-All tariff (the utility buys 100% of production at a fixed rate while the home's consumption is billed normally) or the Netting tariff (monthly netting, but metered production carries a non-bypassable per-kWh 'Solar Energy Adjustment' charge set annually by PURA), and PURA reset both tariff rates for projects enrolling in 2026. |
| State incentive | Residential Renewable Energy Solutions (RRES) Program - the statewide 20-year Buy-All / Netting tariff administered by Eversource and United Illuminating under Conn. Gen. Stat. 16-244z, with income-eligible and other adders; it replaced both legacy net metering and the Connecticut Green Bank's Residential Solar Investment Program (RSIP) |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
Choosing the Netting tariff exposes the homeowner to the Solar Energy Adjustment, a non-bypassable charge PURA re-sets every year on every kWh the panels produce - it is not locked in at signing, and it rose sharply for 2026 enrollments, which materially changes payback math versus the Buy-All option.

What this means for Waterbury roofs
Whether solar still pays in Connecticut after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting Waterbury quotes
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.

Common questions
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
