Answers to common questions about solar installers in Rhode Island.
The best solar installers in Rhode Island are NABCEP-certified, locally based, and transparent about 2026 pricing. NuWatt Energy is a New England solar company that handles REF rebate applications, REG enrollment, and net metering setup as part of every RI installation. Look for installers who disclose that the Section 25D federal tax credit expired December 31, 2025.
Solar installation in Rhode Island costs $3.05-$3.25 per watt in 2026. A typical 10 kW system costs $30,500-$32,500 before incentives. After the REF rebate ($0.65/W up to $5,000), your upfront cost drops to ~$26,500. The REG program then pays $0.27/kWh for 15-20 years. The federal 25D residential tax credit is $0 in 2026.
No. The Section 25D residential solar tax credit expired December 31, 2025. Cash or loan purchases in 2026 receive $0 federal credit. The only way to access federal incentives is through a solar lease or PPA where a third-party owner claims the Section 48 commercial ITC. NuWatt offers this through our Propel financing program.
Rhode Island has excellent state incentives: the REF rebate pays $0.65/W (up to $5,000), the REG program pays $0.27/kWh for 15-20 years, net metering credits at 80% of retail rate, a $2,000 REF battery adder, 7% sales tax exemption, 20-year property tax exemption, and ConnectedSolutions pays $225/kW annually for battery owners.
From signed contract to system power-on, most Rhode Island residential solar installations take 8-12 weeks. This includes design (1-2 weeks), permitting (2-4 weeks), installation (1-2 days), inspection, and Rhode Island Energy interconnection (2-4 weeks). RI is a small state with generally fast municipal permitting.
NuWatt Energy serves all of Rhode Island including Providence Metro, East Bay, South County, Aquidneck Island, Blackstone Valley, and West Bay. Rhode Island is served by a single utility (Rhode Island Energy), which simplifies the interconnection process statewide.
The Renewable Energy Growth (REG) program is a performance-based incentive that pays solar system owners $0.27/kWh for 15-20 years. NuWatt handles all REG enrollment paperwork as part of your installation. A 10 kW system earning REG payments receives approximately $48,600 over the program term.
