How Many Solar Panels Do I Need to Charge My Electric Vehicle?

The use of EVs, or electric vehicles, is on the rise in the U.S. Electric
vehicles offer not only performance but environmental benefits as
well. If you drive an EV it’s likely you have or are in the market for a
charging port for your home.

You’re more likely to find a gas station rather than a charging station when on the road. While some gas stations offer EV charging there are fewer EV stations than traditional gas stations. Having an at-home charging station makes charging your EV always readily available.

Most home charging ports source energy from the grid, but it’s more
efficient and environmentally friendly to source your power through
solar. Some EVs require large amounts of energy to charge, meaning going solar will save you money in the long term.

What’s My EV’s Battery Size?

Before you can figure out how much electricity is required to charge
your vehicle it’s important to know the size of your battery. The battery capacities of EVs are measured in kilowatt-hours, or kWh.Here are the five EVs with the highest capacities:

1. GMC Hummer EV: 200 kWh battery with 329 to 350 miles of range

2. Rivian R1T and R1S: 135 kWh battery with 314 miles of range for the R1T, and 316 miles of range for the R1S

3. Lucid Air: 118 kWh battery with 520 miles of range

4. Mercedes-Benz EQS: 115 kWh battery with 350 miles of range

5. Tesla Model S and Model X: 100 kWh battery with 387 to 520 miles Rhode Island solar quiz see if you qualify

Does Solar Panel Efficiency Matter?

The number of panels you need to power your home and charge your EV depends on three things: Manufacturer/type of panels, the amount of sunlight in your area, and your home/driving energy usage.

Some solar panels are more efficient than others, some panels don’t
require you to own as many.

How Many Solar Panels Do You Need to Charge Your EV?

A typical solar panel is 250 watts and will generate about 30 to 42.5 kWh of energy on a monthly basis. On the lower end of that, you’ll be making about one kWh of energy per day. This means you’d need around 75 solar panels to charge a Tesla Model S to 100% every day if it starts at 0%. Your EV likely won’t be as low as 0% every time you charge it, making this a conservative estimate.

However, if you drive less than the average 39 miles per day and own more efficient solar panels, you’ll need fewer than 12 panels for your
EV charging needs. Investing in high-quality, efficient solar panels is better in the long run.

Additionally, the average home in the U.S. requires between 19 and 34 solar panels to fully cover electric bills. You should expect this
number of panels to increase with the addition of an EV to charge.
