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) + CHEAPR ($500) + Smart-E Loan (0.99% APR) + Energize CT rebates. The 30C credit expires June 30, 2026 and Smart-E runs through 3/31/2026.

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 CT solar production: 2,904 kWh / 1,175 kWh/kW/yr = 2.5 kW of additional solar capacity.
2.5 kW extraDivide by panel wattage: 2,500W / 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 / 1,175 = 2.5 kW
Extra panels: 2,500 / 420 = ~6 panels
Solar upgrade cost: 2.5 kW x $2,980/kW = $7,450
Charger net cost: $1,200 - $1,000 (30C) - $500 (CHEAPR) = $0
Annual electricity savings: 2,904 kWh x $0.27 = $784/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 Connecticut typically take 8-12 weeks from contract to completion (permitting, utility interconnection, inspection). To meet the June 30, 2026 deadline, sign a contract by early April 2026 at the latest.
Level 2 is the standard for home charging. Here is what to know.
Many older CT homes 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.
Connecticut follows NEC 2023 with strict local enforcement. EV chargers require a dedicated branch circuit, GFCI protection, and proper conduit for outdoor installations. All work must be permitted and inspected.
CT shoreline homes face salt air corrosion. Choose NEMA 4X rated chargers and stainless steel mounting hardware for coastal installations. This adds $50-$150 but prevents premature equipment failure.
Your utility determines your charging cost and which programs you can access.

Best for: TOU arbitrage — charge off-peak, export solar during peak hours
Greater Bridgeport & New Haven
Best for: Slightly higher rates mean faster solar payback from EV charging offset
Both Eversource CT and United Illuminating offer TOU rates. Set your EV to charge during off-peak hours (typically 8 PM-12 PM) when rates drop to $0.21-$0.22/kWh. Your solar panels generate during peak hours — that energy offsets your most expensive electricity. Then your EV charges overnight at the lower off-peak rate. This strategy maximizes the spread between what your solar earns and what your EV costs.
CT has unique advantages for EV owners going solar.
The CHEAPR program covers both EV purchase rebates (up to $7,500 for BEVs) and charger installation ($500). Stack the charger rebate with 30C for a $0 net charger while also reducing your EV purchase price.
CT Green Bank's Smart-E Loan offers 0.99% APR financing for solar + EV charger bundles, up to $50,000. This is among the lowest rates in the country for clean energy financing. Program runs through March 31, 2026.
Bundle solar + EV charger + heat pump through Energize CT. The Optimization tier offers up to $10,000 for heat pumps, and your solar system can power the heat pump, EV charger, and home together for maximum savings.
CT's 96-mile coastline means many homes face salt air corrosion on gas equipment. Electric systems (solar, EV, heat pump) with proper NEMA ratings last longer in coastal environments than combustion equipment.
Connecticut pioneered the nation's first green bank. Beyond Smart-E, CT Green Bank offers additional financing products and partners with local credit unions for competitive solar + EV loan packages.
CT's strict building code enforcement means your solar + EV installation is inspected thoroughly. While this adds a week to timelines, it ensures higher quality installations and protects your investment long-term.
Everything homeowners ask about bundling solar with an EV charger.
Most EVs need 2,400-4,900 extra kWh per year (12,000 miles). In Connecticut, that translates to 2-4.2 kW of additional solar, or roughly 5-10 extra 420W panels. CT averages 1,175 kWh/kW/year of solar production, slightly below Massachusetts due to similar latitude.
The Connecticut Hydrogen and Electric Automobile Purchase Rebate (CHEAPR) program offers up to $500 for Level 2 EV charger installation. This stacks with the federal Section 30C credit ($1,000), potentially covering your entire charger cost. CHEAPR is administered by the Connecticut Green Bank.
Yes. The CHEAPR $500 rebate and the federal Section 30C $1,000 tax credit are fully stackable. A typical Level 2 charger installation costs $800-$2,000, so with $1,500 in combined incentives, many CT homeowners pay $0 net cost for their charger.
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. Charger must be placed in service by this date.
Yes. The Smart-E Loan through CT Green Bank offers 0.99% APR for energy improvements including solar panels and EV charger installation. The program runs through March 31, 2026, with loans up to $50,000. This is one of the lowest rates available for solar financing in the US.
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 adds $400-$1,200, for a total of $800-$2,000. After the Section 30C credit ($1,000) and CHEAPR rebate ($500), most CT homeowners pay $0 net cost for their charger.
Eversource Connecticut offers time-of-use rates that benefit EV owners who charge during off-peak hours. The CHEAPR program (statewide) provides the direct EV charger rebate. Energize CT also offers broader home energy incentives that can complement your solar + EV project.
Only if you have a battery backup system with a solar+battery hybrid inverter that can island from the grid. Standard grid-tied solar systems shut down during outages for safety. CT experiences occasional nor'easters and summer storms, making battery backup particularly valuable.
Connecticut uses virtual net metering with 1:1 retail credits for residential solar up to 25 kW. Your solar panels generate credits during the day, which offset the electricity used to charge your EV overnight. Excess credits roll over monthly and are trued up annually.
Lock in the Section 30C credit before June 30, 2026. Our CT-licensed installers handle solar panels, EV charger, and all permitting in one project.
