2026 RHODE ISLAND INCENTIVES
Rhode Island Solar & Battery Incentives Are Stacked Higher Than Ever in 2026
Rhode Island homeowners can combine the Renewable Energy Fund grant and the new Energy Storage Rebate for up to $19,500 off a typical solar-plus-battery system. NEC Solar handles the paperwork.
Funding is limited and first-come, first-reserved
The Rhode Island Energy Storage Rebate Program operates on a reservation basis — once the funding is claimed, it's gone until the next allocation. The state's Renewable Energy Fund also runs in cycles. The homeowners who lock in their rebates are the ones who start the process now.
Four Programs. One Stack. Real Money Off Your System.
Rhode Island lets you combine multiple incentives on the same project. A typical solar-plus-battery install qualifies for tens of thousands in grants, rebates, and credits.
$1.65/W for residential solar up to 8.8 kW. Covers 20–35% of total project cost. Requires a TSRF shade score of 80%+ and a Rhode Island Energy electric account.
Add a qualifying battery concurrently with your REF solar project and receive an extra $5,000 on top of your base grant. Stacks directly — no separate application needed.
Rhode Island's net metering program credits you for every kilowatt-hour your solar system sends to the grid — rolling unused credits forward month to month to offset future bills.
Enroll your battery in Rhode Island Energy's demand-response program and earn automatically each summer — getting paid for sharing stored power with the grid during peak hours.
What This Looks Like on an Actual Rhode Island Home
Here's a real-world example for a typical Rhode Island residential solar-plus-battery system. Numbers are rounded for illustration your NEC consultant will run exact figures for your home.
Are You Eligible?
NEC Solar will verify everything as part of your free consultation — here's a quick checklist.
Stacking four different incentive programs sounds complicated because it is. Most homeowners who try to navigate it alone leave money on the table or miss deadlines. callnec runs the entire process end-to-end.
Free Site Assessment
We measure your roof, run a shade analysis, and confirm your TSRF score qualifies for the REF grant.

Incentive Specialists
Since both programs launched, We've helped our customers receive both the REF grant and ESR rebate with a 100% approval rate. You don't pay extra for the paperwork — it's part of the install.
Workmanship That Holds Up
RI weather is hard on roofs. Our installs are engineered for nor'easters, ice dams, and salt air, with a workmanship warranty backed by NEC Solar — not a third party.
The 30% federal Residential Clean Energy Credit (ITC) expired at the end of 2025 and is no longer available for residential solar installations. Rhode Island homeowners can still access the REF grant plus a battery incentive — either the REF Energy Storage Adder or the ESR rebate — which together cover nearly half the cost of a typical system. Note: the federal ITC may still apply to commercial installations; ask NEC Solar for details.
Total Solar Resource Fraction (TSRF) is a shade analysis score. Your roof must score 80% or higher to qualify for the REF grant. NEC Solar performs this analysis as part of your free site assessment at no cost.
The Energy Storage Rebate (ESR) pays $250 per kWh for residential and small-business systems up to 25 kW, capped at $8,000 per project. Income-eligible households may qualify for $500/kWh, up to $16,000. Note: ESR and the REF Energy Storage Adder cannot be combined — NEC Solar will model both options and recommend which is better for your system.
No. The ESR rebate is available for stand-alone battery installations as well as solar-paired systems. However, if you want the additional $5,000 REF Energy Storage Adder, you'll need a concurrently funded solar project.
Yes. Both the REF and ESR programs operate on a reservation system with capped funding. When the allocated budget is claimed, applications close until the next funding cycle.
Yes. The ESR rebate is available to homeowners with existing solar who want to add storage. Since the REF Energy Storage Adder requires a concurrent solar grant, you'd apply for ESR only — and the two programs can't be combined on the same project regardless.
ConnectedSolutions is a Rhode Island Energy program that pays you for letting the utility briefly draw from your battery during peak demand events. Enrolling can earn you several hundred dollars per year on top of your rebate.
Typical timeline is 8–14 weeks: 1–2 weeks for design and incentive applications, 4–8 weeks for permitting and utility approval, and 1–3 days for the actual install. NEC keeps you updated at every step.
