EV Ownership + Rooftop Solar Ownership — New Report & Charts

December 25th, 2019 by  

We were curious whether EV ownership/leasing correlated with rooftop solar panel ownership, and also whether driving an EV encouraged people to drive more efficiently or even conserve energy more at home, so we surveyed thousands of EV owners. Guess what the results were.

For years, it has been common for businesses, consumers, and environmental activists to link electric vehicles with solar power. In these 2019 surveys, our data again showed that many EV drivers do indeed have rooftop solar power, with more than 30% or even 40% of EV drivers in many of the surveyed countries and EV groups indicating they had rooftop solar.

The group with the highest share was Tesla drivers in the UK (52% of EV drivers had rooftop solar) while the group with the lowest share was plug-in hybrid drivers in North America (just under 32%). In general, a few percent of Brits have solar power and less than 1% of Americans do.

We also asked again whether having an electric car encouraged drivers to save energy while driving (beyond the huge efficiency boost you get inherently from driving electric). As you can see in the charts above, a large majority of drivers said it did, and a decent portion of the respondents were unsure of the connection.

Similarly, we asked if having an electric car encouraged drivers to conserve energy at home. A little more than half of respondents said it did. A bit less than half said it didn’t. Some were unsure of the connection.
