Rhode Island Solar Incentives & Tax Credits
Every solar incentive available to Rhode Island homeowners in 2026.
⚠️
Federal Tax Credit — Expired for Purchases
The 30% federal Residential Clean Energy Credit (Section 25D) expired on December 31, 2025. Homeowners who buy a system with cash or a loan in 2026 can no longer claim it — a $18,275 system that once carried a $5,483 credit now has none.
- ✅ Solar leases and PPAs can still capture a federal credit through 2027 — the installer claims it and lowers your monthly payment
- ✅ State incentives and net metering below still apply to purchased systems
- ✕ No federal credit for cash or financed purchases placed in service after Dec 31, 2025
$7,500
