Key takeaway
Charging at home on a Level 2 charger is how most Milford EV drivers fill up, and rooftop solar can cover most of that cost. Panels produce during the day, National Grid credits whatever you don't use through net metering, and those credits pay for the overnight charge. For trips around town, Milford has fast chargers clustered near I-495, on Fortune Boulevard, Cedar Street, Medway Road and East Main Street.
Who this is for: Milford homeowners with an electric car, or one on the way, who'd rather power it from their own roof than from the grid.
Using Solar to Pay for Home EV Charging
An EV is basically a big new appliance. Plug it into your garage outlet every night and your National Grid bill jumps, because driving a few hundred miles a month takes a lot of electricity.
Solar changes who's paying for those miles. While you're at work or out running errands, the panels on your roof keep producing. Your house uses what it needs and the rest flows out to the grid, where net metering turns it into a credit on your National Grid account. When the car charges overnight, those banked credits cover it. The timing doesn't matter, so you can keep charging after dark like everyone else.
The result: your commute runs on power you made instead of power you bought at a rate that keeps rising. For many Milford households, buying an EV is what tips the math in favor of going solar in Milford, since the panels now have two big loads to offset instead of one.
Tell Your Designer About the EV Early
The most common slip-up is designing the system around last year's bills, then buying a car a few months later. Suddenly the panels are undersized for how the house uses power. If you expect to drive electric anytime soon, bring it up at the first conversation so the system is built for the house and the car together.
Where the Rest of Your Power Comes From
Anything your panels don't cover gets billed through your Milford electricity supply, whether you're on National Grid basic service or Milford Community Electricity. The bigger the share solar handles, the less a rate increase stings.
How Many Panels Does an EV Need?
Figure an EV travels roughly 3 to 4 miles per kilowatt-hour. At 12,000 miles a year, that's somewhere between 3,000 and 4,000 kWh of extra electricity for the house. A kilowatt of solar on a sunny Massachusetts roof produces in the neighborhood of 1,100 to 1,300 kWh a year.
| Yearly miles | Extra electricity (rough) | Added solar to match (rough) |
|---|---|---|
| 8,000 | 2,000 to 2,700 kWh | Around 2 kW |
| 12,000 | 3,000 to 4,000 kWh | Around 3 kW |
| 15,000 | 3,750 to 5,000 kWh | Around 3.5 to 4 kW |
Ballpark figures only. The car you drive, your roof angle, any shade and your driving habits will move the numbers, so a real design should be based on your own usage.
Put simply, a modest bump in system size can cover a daily run on I-495 or out to Worcester.
Level 1 or Level 2?
| Level 1 | Level 2 | |
|---|---|---|
| Power source | Standard 120-volt household outlet | 240-volt circuit, the kind a dryer uses |
| How fast | Adds just a few miles each hour | Fills most batteries overnight |
| What it takes | Usually just plug in | An electrician, a new circuit and a permit |
| Good match for | Plug-in hybrids and short daily drives | Most fully electric cars |
A smart Level 2 charger also works nicely alongside solar. You can schedule charging from an app, and on days you're home you can line it up with the hours your panels are producing the most.
Getting a Level 2 Charger Installed in Milford
- Have your panel checked. An electrician confirms there's capacity for a 240-volt circuit. Older Milford homes sometimes need a panel upgrade first, and if solar is also on your list, doing both at once saves a second round of electrical work.
- Choose a qualifying charger. To collect National Grid's rebate, pick a Wi-Fi smart charger from the utility's approved list.
- Pull the permit. Milford's Department of Inspections issues the electrical permit, and your electrician typically applies for it.
- Install and pass inspection. Once the charger is wired in, the town inspector signs off.
- Send in the rebate paperwork. File with National Grid after the job is done.
National Grid EV Rebates and Other Help
Milford is a National Grid town, so its EV offers are the ones you'll use, alongside the other energy programs in Milford:
- Residential EV Charging Upgrade Program. National Grid offers rebates toward a qualifying smart Level 2 charger and the wiring, for installs done in 2026. Enrolling in National Grid's Off-Peak Charging Program is part of the deal.
- Off-Peak Charging Program. National Grid rewards drivers who charge outside the busiest hours, which the utility puts at about $100 a year.
- MOR-EV. The state's rebate for buying or leasing an eligible electric vehicle. It's a separate program from the charger rebate.
- Solar incentives. Solar incentives in Massachusetts, including net metering and a 15% state tax credit capped at $1,000, stack on top of the EV programs.
EV rebates change often. Confirm the latest rules on National Grid's Massachusetts EV pages and the MOR-EV site before buying anything. There's no longer a federal tax credit for home chargers.
Where to Charge in Public Around Milford
You'll do most of your charging at home, and solar takes care of most of that cost. When you need a quick top-off around town, Milford has a surprising number of fast chargers, many of them close to I-495:
- Target, Fortune Boulevard. Milford's largest fast-charging spot, with six DC fast chargers that work with all EVs, near I-495.
- Nouria, Cedar Street (Route 85). A DC fast charger on the way north toward Hopkinton.
- Nouria, Medway Road (Route 109). Fast charging on the east side of town, heading toward Medway.
- East Main Street. Milford Nissan and Imperial Hyundai both have public fast chargers.
- Level 2 stops. Slower chargers at the Sonesta Select on Fortune Boulevard and by Milford Regional's cancer center on Prospect Street, good if you'll be parked a while.
Public chargers come and go, and some break down. Check PlugShare or the U.S. Department of Energy's station finder before you drive over to see what's working, which plugs it has and what it costs.

Mark, run my numbers!FAQs About EV Charging at Home in Milford
Does solar still help if my EV charges overnight?
Yes. Net metering credits your National Grid account for the extra power your panels make during the day, and those credits are used up when the car charges at night.
How much solar should I add for an electric car?
Plan on roughly 3 kW more for a driver covering around 12,000 miles a year. The exact amount depends on your car, roof and habits, so start the design from your real usage.
Is a permit required for a home EV charger in Milford?
Yes. Installing a Level 2 charger takes an electrical permit from Milford's Department of Inspections, which a licensed electrician usually handles.
Can Milford homeowners get a National Grid EV charger rebate?
Yes, for qualifying smart Level 2 chargers and wiring, as long as you sign up for National Grid's Off-Peak Charging Program. Check the current terms before buying.
What are the best public EV chargers in Milford?
Target on Fortune Boulevard has the most fast chargers. You'll also find fast charging on Cedar Street, Medway Road and East Main Street, plus a few Level 2 stations around town.
