What Connecticut pays for your exported solar power
Export compensation is the single biggest payback lever in 2026. Here is Connecticut's current rule in plain words, with the official source.
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 West Haven homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
West Haven, Connecticut has about 55,379 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
The honest 2026 answer for West Haven: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Connecticut's export compensation, covered in the net metering section.
Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.
The 2026 numbers

| 8 kW | $20,640 | Typical starter system |
| 10 kW | $25,800 | Family home with AC |
| 12 kW | $30,960 | Large home / EV charging |
| Home battery (optional) | $12,000-$16,000 | Backup power + self-consumption |

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 West Haven 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.

Same-day contracts are a red flag in this industry. Legitimate CT installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions
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.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
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.
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.
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.
