Connecticut solar notes
Connecticut replaced net metering with its 'Residential Renewable Energy Solutions' tariff (buy-all or netting options); high retail rates still make solar economically attractive.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and Connecticut may offer its own incentives — check locally.
