Key takeaway
For most Medway drivers, home is where the EV gets charged, and home solar is a great way to pay for it. Your panels produce power during the day, net metering turns the extra into credits on your Eversource bill, and those credits cover your car's overnight charging. Out and about, Medway has public Level 2 chargers at Town Hall, the library, Choate Park and Medway Commons, with faster charging a short drive away.
Who this is for: Medway homeowners who drive electric, are shopping for an EV or want their roof to handle the cost of charging.
How Solar Covers Your EV Charging at Home
Switching to an electric car moves your fuel bill from the gas station to your electric bill. Every night you plug in, the house buys more electricity from Eversource, and with basic service at 17.32 cents per kWh (as of November 2026) before delivery, that adds up fast.
Rooftop solar turns that around. Your panels generate power all day, while the car is at work with you or parked in the driveway. Whatever the house doesn't use flows back to the grid, and net metering gives you a credit on your Eversource bill for it. When the car charges overnight, those credits pay for the electricity. You don't need to time anything. The bill takes care of it.
That's why so many Medway families end up looking at solar for their Medway home right after buying an EV. There's a new, steady electric load, and solar is the most direct way to cover it.
Build the EV Into Your Solar Design
If you size solar off old bills and add an EV later, the system comes up short. If you expect to drive electric in the next couple of years, say so when you get your design. It's much easier to plan for the car now than to add panels to the roof later.
What About the Rest of Your Electricity?
Any power your panels don't cover still comes through your supply, whether that's Eversource basic service or the town's Medway Community Choice program. The more of your charging solar covers, the less a supply rate increase matters.
How Much Solar Do You Need to Charge an EV?
An electric car usually goes about 3 to 4 miles per kWh. Drive 12,000 miles a year and you'll use roughly 3,000 to 4,000 kWh more electricity. In Massachusetts, each kilowatt of solar on a good roof produces about 1,100 to 1,300 kWh a year.
| Annual miles | Electricity the car uses (about) | Extra solar needed (about) |
|---|---|---|
| 8,000 | 2,000 to 2,700 kWh | 2 kW |
| 12,000 | 3,000 to 4,000 kWh | 3 kW |
| 15,000 | 3,750 to 5,000 kWh | 3.5 to 4 kW |
Ballpark figures. Your car, your roof and how you drive will change the real numbers.
For a Medway commuter heading out Route 109 to I-495 every day, that often works out to just a handful of extra panels.
Level 1 vs. Level 2 Charging
| Level 1 | Level 2 | |
|---|---|---|
| Uses | A normal 120-volt outlet | A 240-volt circuit, like a dryer |
| How fast | A few miles of range per hour | A full charge overnight for most cars |
| Installation | Usually none needed | A licensed electrician, a new circuit and a permit |
| Good for | Plug-in hybrids and short trips | Most full-electric drivers |
Smart Level 2 chargers let you schedule charging. If someone's home during the day, you can set the car to charge while your panels are producing.
Installing a Level 2 Charger in Medway
- Check your electrical panel. An electrician makes sure there's room for a new 240-volt circuit. Some homes need a panel upgrade first. If solar is in your plans too, have both looked at together.
- Pick an eligible charger. For Eversource's rebate, choose a qualifying Wi-Fi smart charger from its approved list.
- Get the wiring permit. The Medway Building Department issues wiring permits online, and only a licensed electrician can pull one.
- Install and inspect. The electrician installs the charger and the town's electrical inspector checks the work.
- Apply for the rebate. Submit your Eversource rebate after the charger is up and running.
EV Charger Rebates and Programs in Medway
Eversource delivers power in Medway, so its EV programs apply here, along with other Medway home energy programs:
- Eversource charger rebate. Eversource helps cover a qualifying smart Level 2 charger and the wiring work. The current program requires signing the charger up for managed charging, which moves charging to off-peak hours.
- MOR-EV. The state offers rebates when you buy or lease an eligible electric vehicle, separate from the charger rebate.
- Solar incentives. Net metering and the 15% Massachusetts solar tax credit, up to $1,000, are separate from EV programs, so you can use both.
Rebate rules change often, so check Eversource's Massachusetts EV pages and the MOR-EV website before you buy. The federal tax credit for home chargers is no longer available.
Public EV Charging in Medway
Charging at home is cheaper and easier, especially with solar. When you need a top-off around town, here's where to look:
- Town Hall and the library. The town installed public Level 2 chargers at Town Hall, 155 Village Street, and the Medway Public Library on High Street, funded mainly by a state Green Communities grant.
- Town parks. Medway also lists public chargers at Choate Park on Oak Street and Oakland Park on Oakland Street, plus one at the police station on Village Street.
- Medway Commons. Level 2 chargers in the supermarket parking lot at 65 Main Street let you charge while you shop.
- Main Street. More Level 2 charging is listed at 68 Main Street.
- Faster options nearby. For a quick DC fast charge, head west on Route 109 to the Nouria station on Medway Road in Milford, or north to the fast-charging site on Church Street in downtown Holliston.
Before you go, check PlugShare or the U.S. Department of Energy's station locator for status, plug type and cost, since chargers sometimes go offline.
