Installing a solar system and EV charger together saves money three ways.
One electrician visit, one permit, one inspection. Bundled installation saves $500-$1,000 vs. separate projects. The charger circuit gets wired during the solar panel install.
Your solar installer runs the 240V circuit for the EV charger while they are already on-site for the panel and inverter installation. One disruption instead of two.
Stack Section 30C ($1,000) + National Grid EV rebate ($700) + REG ($0.27/kWh for 15-20 years) + ConnectedSolutions ($225/kW). The 30C credit expires June 30, 2026 - act now.

Four steps from daily driving to panel count.
Start with your annual miles (US avg: 12,000) and your EV's efficiency rating (kWh per 100 miles).
12,000 mi/yrMultiply: (miles / 100) x efficiency. A Tesla Model Y at 24.2 kWh/100mi x 12,000 miles = 2,904 kWh/year.
2,904 kWh/yrDivide by RI solar production: 2,904 kWh / 1,213 kWh/kW/yr = 2.4 kW of additional solar capacity.
2.4 kW extraDivide by panel wattage: 2,400W / 420W/panel = 6 additional panels on your roof.
~6 panels
Annual EV energy: (12,000 / 100) x 24.2 = 2,904 kWh
Additional solar: 2,904 / 1,213 = 2.4 kW
Extra panels: 2,400 / 420 = ~6 panels
Solar upgrade cost: 2.4 kW x $3,060/kW = $7,344
Charger net cost: $1,200 - $1,000 (30C) - $700 (NGrid) = $0
Annual savings: $842/yr electricity + $648/yr REG = $1,490/yr

The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, set the final expiration for the Section 30C EV charger tax credit at June 30, 2026. There is no extension provision. Here is what qualifies - and what does not.
Timeline tip: Solar + EV charger installations in Rhode Island typically take 4-8 weeks from contract to completion (permitting, utility interconnection, inspection). RI is a small state with faster permitting than many neighbors. To meet the June 30, 2026 deadline, sign a contract by early May 2026 at the latest.
Level 2 is the standard for home charging. Here is what to know.
Many older RI homes (especially in Providence and Newport) have 100A or 150A panels. Adding solar + EV charger may require a 200A panel upgrade ($1,500-$3,000). Your installer should assess panel capacity during the site visit.
Rhode Island follows NEC 2020. EV chargers require a dedicated branch circuit, GFCI protection, and proper conduit for outdoor installations. All work must be permitted and inspected by your municipality.
RI homes near the coast should use NEMA 4X (stainless) rated enclosures for salt air resistance. Coastal installations need marine-grade hardware to prevent corrosion. This adds $100-$200 to charger installation.
Your utility determines your charging cost and which programs you can access.
Statewide (~97% of RI)
Best for: Largest utility - full access to NGrid EV rebate, ConnectedSolutions, and REG
Burrillville area
Best for: Lower rate, but limited rebate programs. REG still available.
Block Island
Best for: Highest rate = highest solar savings per kWh. Island solar payback can be fast.
With the REG program, your solar earns $0.27/kWh for all production for 15-20 years. This means every kWh your panels generate - whether it charges your EV, powers your home, or exports to the grid - earns the REG rate. Size your system to cover both home usage and EV charging to maximize total REG income. A 2.4 kW EV solar adder produces roughly 2,911 kWh/year, earning about $786/year in REG income alone.
RI has unique advantages for EV owners going solar.
Rhode Island exempts solar equipment, installation labor, and batteries from the 7% state sales tax. On a $30,000 system, that saves $2,100 upfront. This exemption also covers EV charger equipment when bundled in a solar contract.
The Renewable Energy Growth program pays a guaranteed $0.27/kWh for all solar production for 15-20 years. Unlike net metering, REG pays for every kWh generated, including energy used to charge your EV. A typical solar + EV system earns $1,500-$2,500/year.
Add a battery to your solar + EV system and earn $225/kW per summer through ConnectedSolutions demand response with RI Energy. A 13.5 kWh Powerwall earns approximately $1,350/year in DR payments.
Going all-electric? Clean Heat RI covers 60% of heat pump costs (max $11,500) for standard households, or 100% (max $18,000) for income-eligible. Combine with solar + EV for complete home electrification.
Solar panels do not increase your property tax assessment for 20 years in Rhode Island. A $30,000 solar system that might otherwise add $300-$500/year in property taxes costs you nothing extra.
Rhode Island is the smallest state in the US. This means shorter utility interconnection queues, faster permit processing, and fewer bureaucratic layers than larger states. Most RI solar projects complete in 4-8 weeks.
Everything homeowners ask about bundling solar with an EV charger in RI.
Most EVs need 2,400-4,900 extra kWh per year (12,000 miles). In Rhode Island with 1,213 kWh/kW/yr production, that translates to 2-4 kW of additional solar, or roughly 5-10 extra 420W panels. Efficient sedans like the Tesla Model 3 need fewer panels; trucks like the F-150 Lightning need more.
Yes. Bundling saves on installation costs (one crew, one permit, one inspection), and right now you can stack Section 30C ($1,000 tax credit) + National Grid EV rebate ($700) to get your Level 2 charger for $0 net cost. Plus your solar earns REG income at $0.27/kWh for 15-20 years. The 30C credit expires June 30, 2026.
Section 30C is a federal tax credit for alternative fuel vehicle refueling property, including home EV chargers. It covers 30% of equipment and installation costs, up to $1,000 for residential. It applies to chargers placed in service by June 30, 2026.
The Section 30C credit expires June 30, 2026. The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, accelerated the expiration date. There is no extension mechanism - once it expires, it is gone.
Yes. The Renewable Energy Growth (REG) program pays you $0.27/kWh for all solar production for 15-20 years, regardless of whether that energy charges your EV, powers your home, or goes to the grid. All kWh generated earn the REG rate.
Level 2 (240V, 32-48 amp) is recommended for home charging. It adds 25-37 miles of range per hour, fully charging most EVs overnight. Level 1 (120V) only adds 3-5 miles per hour, which is impractical for daily commuters unless you drive under 30 miles/day.
A Level 2 charger unit costs $400-$800, and professional installation (240V circuit, wiring, permit) adds $400-$1,200, for a total of $800-$2,000. After the Section 30C credit ($1,000) and National Grid EV rebate ($700), many homeowners pay $0 net.
Yes. Add a battery to your solar + EV system and earn $225/kW per summer through ConnectedSolutions demand response. Your solar charges both the battery and your EV. The battery then earns DR income during peak events while your EV charges overnight.
Only if you have a battery backup system (like Tesla Powerwall) with a solar+battery hybrid inverter that can island from the grid. Standard grid-tied solar systems shut down during outages for safety. With a battery, you can charge your EV from stored solar energy.
No. Rhode Island exempts solar equipment, installation labor, and batteries from the 7% state sales tax. EV charger equipment purchased separately is subject to sales tax, but when bundled with a solar installation and included in the solar contract, the entire project typically qualifies for the solar sales tax exemption.
Lock in the Section 30C credit before June 30, 2026. Our RI-licensed installers handle solar panels, EV charger, and all permitting in one project.
