Electric Vehicle Charging

When you pair solar power with EVs, you break the connection between driving and carbon pollution and take a big step toward energy independence. By budgeting a PV system as part of an EV’s cost, you create a valuable charging package that gives you a better return on investment, and produces free energy for your car and home for years to come.

Most all-electric vehicles on the market are capable of over 100 MPGe, and with the average eGallon price of $1.85 in Northern New England, it’s easy to visualize significant savings.

But what about the solar gallon? It’s like the eGallon, but thanks to solar power it emits no carbon, has no significant hidden environmental costs, and leaves a much lighter footprint on society. A solar gallon also happens to cost $0.84.*

The best part? The solar gallon is locked in over the lifetime of your solar array! With an EV, your cost savings on gas accelerates the payback of your solar investment, and after the array is paid for in fuel savings, you will essentially receive free power for the life of the system. A fixed rate of $0.84 per eGallon is evidence of the unbeatable synergy of solar and EVs.

*The solar gallon is a slightly conservative estimate based upon average efficiencies of both motor vehicles and EVs, factored with the levelized cost of a typical residential solar array that provides charging. It uses the average fuel efficiency of American cars from 2020 from the EPA (25.4 mpg) and compares to average efficiency of EVs (0.346kWh/mile).

Solar Powered EVs: Transportation's Clean Future 

With electricity, we now have a choice as to how to power our cars. Using electricity produced within the United States for our transportation needs is a big leap away from reliance upon foreign oil, and when we use locally generated solar electricity to power vehicles – drastically reducing the greenhouse gases involved before – we leap to where we really ought to be.

Driving on sunshine is the fullest realization of EVs on the road. By unifying EVs and solar, we create enormous savings, greatly reduce environmental harm, and strengthen America’s energy independence – that, is the world’s first truly reliable car.

If you want to drive an electric vehicle, you’re going to need an electric vehicle charging point at home, either mounted in the garage or on the driveway.

To charge your electric vehicle with solar, you need two components: a solar electric system and a Level Two electric vehicle charging station. ReVision Energy can install both for you. A wall-mounted Level Two charger can deliver about 25 miles of range per hour of charging, allowing you to wake up every morning to a fully-charged vehicle.

Level Two charging is much faster than, and highly preferable, to Level I plug-in outlet charging which typically delivers 4-5 miles per hour of charging. A Chevy Bolt, for example, takes only 8.5 hours (overnight) to recover its 238-mile range with a Level Two charger, and over 36 hours with a Level One charger.

A grid-tied solar electric system is the best way to put solar to work for your electric car. A grid-tied system will produce power whenever the sun is out, regardless of whether your house needs it that moment. So, if you are at work (and charging there!), the power generated at your home will be sold to the grid. You get that power back in the form of a credit, which you can use at night while re-charging your EV.

Major automakers like Volvo and GM have recently declared the future to be all-electric. There are many all-electric cars already available in the US, as well as hybrid EVs. Battery ranges have increased, model types have diversified, and costs have come down. So what’s out there?

Perhaps everyone has heard of Tesla by now. They continue to push the market ahead, and the Model 3 has brought their great battery range and design closer to the reach of an average American income, but the top contender for best American EV might just be from one of the oldest gas-powered vehicle makers: Chevrolet. The Chevy Bolt was the 2017 Motor Trend Car of the Year, as it is a powerful combination of quality, efficiency, and value.

Another strong all-electric option is the Nissan Leaf, or there are many plug-in hybrids like the Chrysler Pacifica, Toyota Prius Prime or Kia Niro. Plug-in hybrids (PHEVs) offer gasoline power as a backup to battery range. The average American commute is usually short enough for a PHEV to drive on electricity most of the time, however, there is still an engine that needs to be maintained. In contrast, all-electric EVs are free from many maintenance needs we have become accustomed to with car care.

Erik, a Solar Designer for ReVision, has a Tesla Model 3 and Clipper Creek Level Two charging station:

Driving electric has been an awesome experience and I have zero regrets in making the switch. I was honestly a bit hesitant at first because it was such a foreign concept to me, but it has made driving fun again and my commute to work is one of the best parts of my day. Merging onto the highway on an on ramp and blasting out of a toll booth with rapid acceleration are especially fun, it never gets old!

I put a Clipper Creek Level Two charging station in my garage which gets me about 25 miles of range per hour of charge, so fully recharging overnight is easy. I can also charge at work at one of the multiple Level Two Charging Stations there.

Maintenance? Well, in the 2 years that I’ve owned the Tesla Model 3, I’ve rotated the tires once and refilled the windshield washer fluid 3 times. Oil changes and noisy mufflers are a thing of the past for me. Warming the vehicle up inside the garage in the wintertime without filling the entire garage with Carbon Monoxide is pretty nice too.

Cleaning up New England’s transportation sector is critical in the fight to lower our region’s CO2 emissions. Driving an electric vehicle that is oftentimes charged by the solar array at my home or at work gives me entertaining, guilt free driving and I can’t recommend it enough!

Dylan, another Solar Champion, has had a great experience driving a Bolt:

Two years and 43,000 miles into owning a Chevrolet Bolt, I have only paid $50 to charge at a couple of DC fast chargers.

After weekends full of events and staying with friends, while driving from Portland to Boston, to the White Mountains, I have taken breaks from driving and fully charged while eating lunch.

How have I gotten away with zero tailpipe emissions and near zero fuel cost? Home rooftop solar, and visiting businesses that provide complimentary charging.

At home, I wake up with 240 miles in my “tank” every day, so I really only need to charge once or twice a week. I am no longer going out of my way to search for a gas station to stand in the cold, sideways rain or snow, fiddling with a credit card at a sticky gasoline pump. Chargers are conveniently located at my destinations — I just check PlugShare!

When in cities, garages that offer charging get my business. When at ski slopes, I can even preheat my car from the chair lift on the last run, while it’s still plugged in, so it’s fully charged and warm when I’m ready to leave.
