What makes an EV good for solar
Any EV can run on solar power. But some make it much easier, and cheaper, than others. If you have solar panels or plan to get them, three things matter most:
How efficient the car is: fewer kWh per mile means fewer panels.
How well it works with your solar: can it charge only from spare solar, or does it pull from the grid when a cloud passes?
Whether it can power your home in a blackout.
Here are our picks for 2026, and how to choose the right one for your home.
Our picks at a glance
EPA ratings are for the versions named. Panel counts use the same assumptions as our calculator: 15,000 miles a year, the US average of about 4.98 peak sun hours a day, 18% system losses and 400 W panels, rounded up. Home backup needs the carmaker's equipment, bought separately.
| Car | EPA energy use | Panels for 15,000 mi | Solar charging and home backup | Best for |
|---|---|---|---|---|
| Tesla Model Y Long Range | 29 kWh/100 mi | 8 | Charge on Solar built in (needs a Powerwall). Home backup on new cars with a Powerwall 3. | Best all-round choice |
| Hyundai IONIQ 6 Long Range RWD | 24 kWh/100 mi | 7 | Needs a solar-aware charger. No home backup. | Fewest panels |
| Chevrolet Equinox EV (FWD) | 31 kWh/100 mi | 8 | Needs a solar-aware charger. Home backup with GM Energy V2H Bundle. | Efficient SUV with home backup |
| Chevrolet Silverado EV | 48 kWh/100 mi | 13 | Needs a solar-aware charger. Home backup with GM Energy V2H Bundle. | Longest home backup |
| Ford F-150 Lightning (2022–2025, used) | 48 kWh/100 mi | 13 | Needs a solar-aware charger. Ford's home backup system no longer sold new. | Job-site power |
Tesla Model Y: best all-round choice
The Model Y is efficient, at 29 kWh per 100 miles, and it's the only car here with solar charging built into its own app. Tesla's Charge on Solar feature lets the car charge only with your spare solar, adjusting about every 10 seconds, as long as you also have a Tesla Powerwall at home. New Model Y cars ordered in the US from October 1, 2026 can also back up your home in an outage when paired with a Powerwall 3.
Hyundai IONIQ 6: fewest panels
The IONIQ 6 Long Range RWD (with 18-inch wheels) is one of the most efficient cars sold in the US, at 140 MPGe, or 24 kWh per 100 miles. That means fewer panels: about 7 for 15,000 miles a year, compared with about 13 for a big truck. It doesn't have built-in solar charging or home backup, but pair it with a solar-aware charger and it's the cheapest car here to run on sunshine.
Chevrolet Equinox EV: efficient SUV with home backup
The front-wheel-drive Equinox EV uses about 31 kWh per 100 miles, close to the Model Y. It also works with GM's V2H Bundle, so it can power your home during an outage. If you want an affordable family SUV that can double as a backup battery, it's a strong choice.
Chevrolet Silverado EV: longest home backup
The Silverado EV is thirsty on the road, at about 48 kWh per 100 miles, so it needs many more panels. But its biggest battery holds about 200 kWh, enough to run an average home for several days with GM's V2H equipment. If you live with hurricanes, ice storms or long outages, that's a big plus.
Ford F-150 Lightning: job-site power (used only)
Ford stopped making the electric Lightning in December 2025, so it's now a used-market buy. Its built-in outlets (Pro Power Onboard) are great for running tools on a job site. Owners who already have Ford's home backup system can keep using it, but it's no longer sold new.
Efficiency decides how many panels you need
The EPA measures EV efficiency in kWh per 100 miles; lower is better. For 15,000 miles a year with average sunshine, a truck at 48 kWh per 100 miles needs about 13 panels. A sedan at 24 needs only about 7. At $3.00 per watt with no tax credit, that difference is about $7,200 in solar costs.
Smart charging decides how much of your solar you actually use
A basic charger pulls full power the moment you plug in. If your panels aren't making enough, say when a cloud passes, the rest comes from the grid. A solar-aware setup speeds up and slows down to match your spare solar.
Tesla does this in the car's own app, with a Powerwall. For any other car, you can use a solar-aware charger such as the Emporia Pro, Enphase IQ EV Charger 2 or Wallbox Pulsar Plus with its power meter. These work with almost any EV.
Choose based on your situation
Your car is at work all day: daytime solar charging won't help much on weekdays, because you'll charge at night. Focus on efficiency (like the IONIQ 6), since a thrifty car uses less of the solar credit your panels earn during the day.
You already have solar: if you have Enphase microinverters, Enphase's charger is easy to add. A clamp-based charger like the Emporia Pro works with almost any inverter brand. Either way, you don't need a Tesla to charge from spare solar.
You live somewhere cold: all EVs lose range in freezing weather, mainly to heat the cabin and battery. A heat pump helps, so check the version you're buying has one. Look at real-world winter data, such as Recurrent's, before you decide.
Outages are common where you live: pick a car with home backup (V2H), and budget for the equipment, which costs several thousand dollars. See our guide to EVs that can power your home.
An example: same Saturday, two different results
It's a sunny Saturday afternoon. Ryan and Lisa both plug in their cars at home. Both roofs are making about 5 kW, and both homes are using about 1 kW.
Ryan has an electric crossover and a basic charger. The charger immediately pulls 9.6 kW. His panels have only about 4 kW to spare after running the house, so about 5.6 kW comes from the grid at his normal electricity rate.
Lisa has a Tesla Model Y, solar and a Powerwall, and she's turned on Charge on Solar. Her car charges at about 4 kW, just what her roof can spare. When a cloud passes, it slows down; when the sun returns, it speeds up again. Her charging runs almost entirely on her own sunshine.
Ryan doesn't need a new car to get the same result. A solar-aware charger would do the same job for his crossover.
