The federal 25D tax credit is gone. Most installers haven't updated their quotes. NuWatt is licensed, bonded, and insured in Rhode Island — and we'll tell you exactly what your system costs in 2026 with no bait-and-switch. Plus, we maximize RI's excellent REF + REG incentives that most national installers miss entirely.
With the federal residential solar tax credit dead, the installer you choose determines whether you overpay, miss RI-specific incentives, or access the last remaining federal savings path.
Section 25D — the 30% residential solar tax credit — expired December 31, 2025. If you buy a system with cash or a loan in 2026, your federal credit is $0.
Any installer still quoting you a 30% federal credit for a purchased system is either uninformed or dishonest.
Section 48/48E — the commercial ITC — is still active for projects beginning construction before July 4, 2026. A third-party system owner (not you) claims the credit.
Through a solar lease or PPA, the financing company claims the 30% ITC and passes the savings to you as a lower monthly payment.
We offer both paths: honest cash/loan pricing at $0 federal credit, and our Propel lease program that accesses Section 48 savings on your behalf.
Either way, we maximize RI's REF rebate ($5,000+) and REG income ($0.27/kWh for 20 years) — programs national installers routinely miss.
The federal credit is gone, but Rhode Island still has one of the best state incentive stacks in New England. NuWatt enrolls you in every program you qualify for — most competitors skip at least one.
Commerce RI's Renewable Energy Fund pays $0.65 per watt, capped at $5,000. On an 8 kW system, that's the full $5,000. Plus a $2,000 battery adder if you add storage.
Learn moreThe Renewable Energy Growth program guarantees $0.27/kWh for every kilowatt-hour your system produces. At 8 kW, that's ~$2,400/year guaranteed for up to 20 years.
Learn moreExport excess solar and get credited at 80% of the retail rate (~$0.23/kWh). Grandfathered systems get 1:1 credits. 125% annual production cap.
Learn moreBattery owners earn $900-$1,100/year by allowing brief discharge during summer peak demand events. Pairs perfectly with the $2,000 REF battery adder.
Learn moreNo sales tax on solar equipment, installation labor, or batteries. On a $26,000 system, that's $1,820 in immediate savings.
Learn moreSolar panels increase your home value but your property tax stays the same for 20 years. Saves approximately $400-$700/year depending on your town.
Learn moreWe're not a marketplace. We're not a national chain with subcontracted crews. We're a New England solar company that knows Rhode Island's incentive programs, permitting requirements, and utility rules better than anyone.
We've been installing solar across New England since 2008 — through policy changes, panel shortages, and now the ITC expiration. We'll be here for your warranty.
The gold standard in solar certification. Only ~10% of solar installers in the US hold this credential. Every NuWatt RI project is supervised by a NABCEP-certified professional.
We handle your REF rebate application ($5,000), REG enrollment ($0.27/kWh for 20 years), net metering, and ConnectedSolutions signup — all included in our service.
One of the few RI installers certified to install Tesla Powerwall 3. We also install Enphase IQ and Franklin aPower batteries — all eligible for the $2,000 REF battery adder.
Our installation teams are NuWatt employees, not day-labor subcontractors. Same quality, accountability, and safety standards on every job across Rhode Island.
Published $/W rates. No hidden adders, no "system design fees," no surprise change orders. What we quote is what you pay — with $0 federal credit clearly stated.

Three ways to go solar in Rhode Island. Here's how they compare on the factors that matter most in 2026.
| Factor | NuWatt (Direct) | Marketplace (e.g. EnergySage) | National Chain (e.g. Sunrun) |
|---|---|---|---|
| Post-ITC Honesty | Transparent: $0 federal credit for cash/loan purchases in 2026 | Many listings still show outdated 30% ITC in estimates | Sales reps may reference expired credits to close deals |
| Section 48 Lease/PPA | Propel lease passes Section 48 savings to homeowner | Varies by installer — no guarantee of 48 access | PPAs available but lock-in terms may be unfavorable |
| RI Program Expertise | REF rebate, REG enrollment, net metering, ConnectedSolutions — all handled by us | Installer may or may not handle program enrollment | Often skip REF/REG enrollment entirely |
| Equipment Quality | Hyundai/Silfab/REC panels, Enphase microinverters | Equipment varies widely by installer | Proprietary or limited equipment choices |
| Pricing Transparency | Published $/W pricing, no hidden fees | Must request quotes from 3-5 installers to compare | Opaque pricing, high-pressure sales tactics |
| Local Presence | New England-based team, same-day service response | Connects to local installers (quality varies) | Subcontracted crews, limited local accountability |
| Warranty Support | 25-year panel + 25-year Enphase + 10-year workmanship | Depends on the installer you choose | Good panel warranty, but service via call centers |
Our Propel lease program lets a third-party financing company claim the Section 48 commercial ITC on your behalf. You get solar at a locked-in monthly rate lower than your current Rhode Island Energy bill — with the federal savings built in.
From first call to power-on in 8-12 weeks. We handle everything — including REF applications and REG enrollment.
Satellite analysis + optional site visit. We evaluate your roof, shading, electrical panel, and RI Energy rate. You get a detailed proposal with real 2026 pricing — $0 federal credit clearly stated.
Custom engineering, structural review, building permit, utility interconnection application, REF rebate filing, and REG enrollment. We handle every piece of paperwork.
Our own certified crews install panels, inverters, and battery (if applicable). Most residential installs in Rhode Island complete in 1-2 days.
Municipal electrical inspection, utility meter swap, and final interconnection with Rhode Island Energy. You flip the switch and start generating clean energy.

Rhode Island's solar market includes national chains, local installers, and marketplace-connected companies. Here are the red flags and green flags for 2026.
Common questions Rhode Island homeowners ask about going solar in 2026 — answered honestly.
Yes. NuWatt Energy is licensed, bonded, and insured to perform solar installations in Rhode Island. We are NABCEP-certified, Tesla Powerwall Certified, and A+ BBB rated. We have completed over 400 residential and commercial solar installations across Rhode Island.
No. The Section 25D residential solar tax credit expired on December 31, 2025. Cash and loan purchases receive $0 in federal credits. The only way to access federal incentives in 2026 is through a Section 48 lease or PPA, where a third-party system owner claims the commercial ITC and passes savings to you as a lower monthly payment. NuWatt offers this through our Propel lease program.
Rhode Island has excellent state-level incentives: the REF rebate pays $0.65/W (up to $5,000) plus a $2,000 battery adder, the REG program guarantees $0.27/kWh for 15-20 years, net metering credits at 80% of retail rate, ConnectedSolutions pays $225/kW for battery demand response, 7% sales tax exemption on equipment and labor, and a 20-year property tax exemption. With REF + REG combined, RI has one of the best incentive stacks in New England.
Without the federal ITC, Rhode Island solar costs $3.05-$3.25 per watt installed in 2026. A typical 8 kW system costs $24,400-$26,000 before state incentives. After the $5,000 REF rebate, REG income, and net metering savings, payback is typically 7-9 years. With a Section 48 Propel lease, monthly payments start lower than your current electric bill with $0 down.
The Renewable Energy Growth (REG) program pays solar system owners $0.27/kWh for every kilowatt-hour their system produces, guaranteed for 15-20 years. Enrollment opens annually on April 1 and fills quickly. NuWatt handles the entire REG application process, including system sizing to maximize your allocation, paperwork submission, and compliance. Our REG acceptance rate is over 95%.
NuWatt is a direct New England solar installer — we design, permit, install, and maintain your system with our own crews. National chains like Sunrun or Tesla use subcontracted labor and centralized call centers. Most critically, NuWatt handles REF rebate applications, REG enrollment, and ConnectedSolutions signup — programs that national installers often skip because they lack local expertise. Our team knows Rhode Island permitting, utility rules, and incentive programs inside and out.
NuWatt serves all of Rhode Island including Providence Metro, East Bay, South County, Newport County, Northern RI, Kent County, Blackstone Valley, and Block Island. We handle installations in Rhode Island Energy territory (which serves ~99% of the state), as well as Pascoag Utility and Block Island Power areas.
From signed contract to power-on, most residential installations take 8-12 weeks. This includes engineering (1-2 weeks), permitting (2-4 weeks), installation (1-2 days), electrical inspection, and utility interconnection (2-4 weeks). NuWatt handles all permitting, utility paperwork, REF rebate applications, and REG enrollment.
Yes. We are Tesla Powerwall Certified Installers and also install Enphase IQ batteries and Franklin aPower systems. Rhode Island is great for batteries thanks to ConnectedSolutions, which pays $225/kW annually for participating in summer demand response events. A Powerwall can earn $900-$1,100/year in ConnectedSolutions revenue. Plus, the REF program offers a $2,000 battery adder on top of the base $5,000 solar rebate.
The Propel lease lets a third-party financing company own your solar system and claim the Section 48 commercial ITC (still active for projects starting construction before July 4, 2026). The 30% federal credit savings are passed to you as a lower monthly lease payment. You get $0 down solar with day-one savings on your electric bill. The system uses FEOC-qualified Silfab 440W panels to maximize the ITC bonus. NuWatt installs and services the system locally for the full 25-year term.
