*Mass Save rebate ($300-$800) subject to utility and managed-charging enrollment. The federal Section 30C credit for home EV chargers expired June 30, 2026.
Massachusetts is one of the best states for EV charger incentives. Here is how to maximize your savings with Mass Save, off-peak rates, and the MOR-EV vehicle rebate.
The Section 30C credit that gave residential EV charger buyers up to $1,000 (30% of equipment and installation costs, claimed on IRS Form 8911) expired June 30, 2026 and is no longer available for home chargers installed after that date. Massachusetts savings now come from Mass Save and off-peak EV rates.

$300 off a qualified Level 2 EV charger from participating utilities (Eversource, National Grid, Unitil, Cape Light Compact). Enroll in their managed charging program for an additional $500 off — the utility occasionally adjusts your charging schedule during peak demand (you set the boundaries). Total Mass Save savings: up to $800.
$300-$800
Ongoing program
Not a charger rebate, but worth noting: Massachusetts offers up to $3,500 for new EVs and $1,500 for used EVs through the MOR-EV program. Income-qualified buyers can receive up to $5,000. If you are buying an EV and a charger together, the combined savings are significant.
$1,500-$5,000
For the vehicle
*Mass Save managed charging requires enrollment. The federal Section 30C credit for home EV chargers expired June 30, 2026. Actual savings depend on install complexity and eligibility.
NuWatt installs EV chargers as part of our solar + storage + EV bundle. Here is why pairing solar with your EV charger is the smartest financial move.
Gasoline Car (12,000 mi/yr, 28 MPG, $3.50/gal)
$1,500/year in fuel
EV on Grid Power (12,000 mi/yr, $0.36/kWh Eversource)
$1,300/year in electricity
Saves ~$200/yr vs. gas
EV Charged from Solar (own your power)
~$0/year in fuel
Saves ~$1,500/yr vs. gas
One crew, one permit, one project
We install solar, battery, and EV charger in a single visit — saves $500-1,000 in separate mobilization costs.
Right-size the solar system
We add 2-3 kW to your solar array to cover EV charging. A typical EV adds ~3,000 kWh/year of demand.
Smart charging from solar
With the Emporia Smart Charger or JuiceBox, you can schedule charging during peak solar production hours for maximum self-consumption.
Panel capacity planning
We assess your panel capacity upfront. If you need a 200A upgrade for solar + EV, we do it once — no repeat electrician visits.
$1,200-$1,800/year in fuel savings
The average MA EV driver who charges from solar saves $1,200-$1,800 per year compared to gasoline. Over 10 years, that is $12,000-$18,000.
Massachusetts utilities are rolling out EV-specific rate plans that can cut your charging costs by 30-50% compared to standard rates.
Eversource offers a whole-home time-of-use (TOU) rate for EV owners. Off-peak hours (9 PM - 1 PM weekdays, all weekends) offer significantly lower rates, making overnight EV charging much cheaper than standard rates.
Smart chargers can auto-schedule to charge only during off-peak hours, saving you 30-40% on charging costs without any effort.
National Grid is expanding EV programs in Massachusetts, including managed charging incentives and potential future vehicle-to-grid (V2G) programs. Their off-peak rate options help reduce charging costs for residential customers.
National Grid customers pay more per kWh overall, making the solar+EV charger bundle even more compelling — generate your own power and avoid grid rates entirely.
A Level 2 EV charger at 48A needs a 60A breaker. If your panel is already near capacity, you may need an upgrade — or a smarter alternative.
You have a 200A panel with 40+ amps of available capacity. Most homes built after 2000 fall into this category.
Cost: $0 extra
A smart panel or load management device (like Span or Lumin) dynamically shares capacity between your EV charger and other loads. Avoids a full panel upgrade.
Cost: $500 - $1,500
If your home has a 100A or 150A panel (common in older MA homes built before 1980), a full upgrade is the safest option for solar + EV + heat pump loads.
Cost: $2,000 - $4,000
We assess your electrical panel during the site survey — before you commit to anything. If you are bundling solar + EV charger (or adding a heat pump), we plan the panel capacity for all loads at once. This avoids paying for an electrician visit now and another one later. Many MA homes built in the 1960s-1980s have 100A panels that need upgrading regardless — doing it alongside your solar install saves $500-1,000 versus a standalone panel upgrade.
Massachusetts is accelerating EV adoption with strong state policy, generous incentives, and expanding charging infrastructure. Here is what is driving the shift.

Public charging stations statewide
Over 80% of EV charging happens at home. Public charging stations are convenient for road trips, but daily charging should happen in your garage or driveway. A Level 2 home charger provides:
The economics are clear: home charging costs 50-70% less than public fast charging and is infinitely more convenient. Add solar panels and your marginal charging cost drops to effectively zero.
Annual Charging Cost Comparison (12,000 mi/yr)
Total cost ranges from $700 to $5,200 depending on your electrical setup. A basic install with an existing 240V outlet near the panel runs $700-1,200 (charger + labor). A standard install requiring a new dedicated circuit costs $1,200-2,200. Complex installs needing a panel upgrade to 200A or long wire runs to a detached garage can reach $2,500-5,200.
No. The Section 30C Alternative Fuel Vehicle Refueling Property Credit, which provided up to $1,000 for residential EV charger installations, expired June 30, 2026 and is no longer available for home chargers installed after that date. Massachusetts homeowners can still save through Mass Save: $300 off a qualified Level 2 charger plus up to $500 for enrolling in a managed charging program (up to $800 total), along with off-peak EV rates from Eversource and National Grid.
Yes. Mass Save offers $300 off a qualified Level 2 EV charger through participating utilities (Eversource, National Grid, Unitil, Cape Light Compact). Enrolling in a managed charging program can earn an additional $500 off — up to $800 total off your charger installation. Pair it with off-peak EV rates and a solar+EV bundle for the biggest long-term savings.
Not always. A 48A Level 2 charger needs a 60A breaker and draws significant capacity. If your home has a 200A panel with available capacity, no upgrade is needed. If you have an older 100A or 150A panel, you may need an upgrade ($2,000-4,000) or a smart panel/load management device ($500-1,500) that dynamically shares capacity between your EV charger and other high-draw appliances.
A 48A Level 2 charger (11.5 kW) adds about 35-44 miles of range per hour. A typical EV with a 60 kWh battery charges from 20% to 80% in roughly 4 hours. Most MA drivers commute 30-40 miles/day, so overnight charging easily replenishes daily driving. Even a slower 40A charger (9.6 kW) at ~30 miles/hour handles most daily needs.
Yes, and it is one of the biggest cost advantages of pairing solar with an EV charger. A typical 8 kW solar system in Massachusetts produces about 9,500 kWh/year — enough to power both your home and 10,000-12,000 miles of EV driving. Charging from solar effectively gives you $0 fuel costs, saving the average MA EV driver $1,200-1,800 per year compared to gasoline.
The Tesla Wall Connector uses the NACS (Tesla) connector natively. Non-Tesla EVs with NACS ports (newer models from Ford, GM, Rivian, etc.) can plug in directly. Older EVs with J1772 ports need a NACS-to-J1772 adapter ($35-50). The ChargePoint Home Flex or Emporia Smart Charger with J1772 connectors are more universal if you have mixed EV brands in your household.
Buy a Level 2 charger on the Mass Save Qualified Product List and have it installed by a licensed electrician, then apply through your utility (Eversource, National Grid, Unitil, or Cape Light Compact) for the $300 rebate. To earn the additional $500, enroll the charger in your utility managed charging program, which lets the utility make limited adjustments to your charging schedule during peak demand within limits you set. Combined, that is up to $800 off your installation.
NuWatt installs EV chargers across Massachusetts — standalone or bundled with solar and battery storage. We handle permitting, electrical work, and utility coordination. Average install time: 2-4 hours. Average booking lead time: 2-4 weeks.
