Home solar in Rhode Island: prices, net metering, what is left in 2026
What Rhode Island homeowners pay for solar in 2026, how the state's export rules work, and which incentives survived - verified against state sources, town by town.
Installed home solar in Rhode Island compares against the U.S. marketplace average of about $2.58 a watt - roughly $30,960 for 12 kW.
The 30% federal solar credit ended December 31, 2025 - Rhode Island installations completed in 2026 get $0 from it.
A home battery in Rhode Island runs about $12,000-$16,000 installed, before any state storage incentive.
Whether solar still pays in Rhode Island 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.
Rhode Island rules that decide your payback
| Rule | Rhode Island status |
|---|---|
| Export compensation (net metering) | Net metering credits are paid for generation up to 100% of on-site consumption (systems may be sized up to 125% of usage based on a three-year consumption average), anything produced above 100% is credited only at the utility's avoided-cost rate (the last-resort service charge), and for projects initiated after April 15, 2023 the renewable net-metering credit is reduced by 20%, subject to a 275 MW cap; homeowners may instead elect the Renewable Energy Growth tariff, but not both. |
| State incentive | Renewable Energy Growth (REG) Program - Small-Scale REG is open to homeowners for projects 25 kW and smaller, opens each year on April 1 and runs first-come, first-served until fully subscribed, paying a fixed long-term performance tariff instead of net metering; the Renewable Energy Fund (REF) Small-Scale Solar grant, administered by RI Commerce, is also available during open solicitation periods |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
Governor McKee's Executive Order 26-01 (February 9, 2026) orders a comprehensive review of both the Net Metering Program and the REG Program - citing 250%+ net metering growth over five years borne entirely by ratepayers - with findings and legislative options due to the Governor by October 1, 2026, so Rhode Island's residential solar compensation could change within the year.

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.
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.
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.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
How do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
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.
