Nearly 1,500 California plug-in vehicle owners responded to the survey, which CCSE and ARB are calling the largest survey of its kind ever.
Zeroing in on EV + PV While the survey generated lots of interesting data, some of which you can view quickly and easily via the info-graphic at the bottom of this story, of greatest interest to SolarChargedDriving.Com are the numbers on PV + EV, or solar-charged driving.
In fact, it’s notable that the survey devotes more than a page – out of nine pages total – to various questions regarding EV owners and home solar.
This clearly shows, as do the survey numbers themselves, that solar-charged driving is a big deal, at least in terms of the admittedly somewhat out-of-the mainstream people who have tended to be those who’ve purchased or leased plug-in vehicles so far.
Among the survey’s most interesting EV + PV findings:
39 percent of respondents already have a home solar PV system;
An additional 17 percent said they plan to add home solar. This pushes the total of current and future solar-charged respondents to 56 percent, or more than 700 respondents! If this survey is representative of the U.S. as a whole, where, in the past 1 ½ years, about 20,000 new plug-in vehicles have been sold, there could be up to 10,000 solar-charged drivers in the U.S. right now. However, because it’s likely that a higher percentage of California plug-in vehicle owners have home solar than those in other states, the number of solar-charged drivers in the U.S. probably isn’t that high. Still, it seems virtually certain that, at the very least, there are several thousand EV owners currently plugging into solar-charged driving in the U.S. While that might not seem like a lot, it’s a lot more than when we founded SolarChargedDriving.Com approximately three years ago.
Approximately 60 percent of survey respondents who did not initially size their home solar PV system for their plug-in vehicle stated that they plan to expand their system within the coming year.
95% have gas car too Another notable survey finding is the fact that 95 percent of plug-in vehicle owners own at least one conventional fuel vehicle.
This fact almost certainly plays a significant role in another very interesting fact: Namely, the fact that 83 percent of respondents indicated that they use their plug-in vehicle as their primary car, driving, on average 800 pure EV miles per month.
The high percentage of respondents living in a two-car household (nearly 60 percent of American households are two-car households), with one being a conventional fuel vehicle, lends solid support to something we at SolarChargedDriving.Com have contended for a long time: Namely, that grand statements about range anxiety are overstated.
That’s because big generalizations about range anxiety fail to account for the fact that a majority of American households are two-car households, or for the fact that, in many, if not most, of these households, a plug-in vehicle used almost exclusively in electric mode for commuting, trips around town, etc. plus a gasoline car used for the occasional long trips works perfectly fine.
