Is there still a solar tax credit for Stonington homeowners in 2026?
The 30% federal credit is gone for 2026 installations. What survives for Stonington: Connecticut's own incentives and tax treatment - verified against state sources.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Stonington systems completed in 2026 get $0 from it.
Installed home solar for Stonington homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Stonington, Connecticut has about 1,012 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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.
If a salesperson in Stonington tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Connecticut's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

The 30% federal tax credit is gone for 2026 installations
The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts 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 Stonington roofs
The honest 2026 answer for Stonington: 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.

Getting Stonington quotes
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
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.
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
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.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
