Key takeaways


If you're driving an electric vehicle (EV), the chances are you're eyeing your roof for solar panels next. This interesting trend has been revealed by a recent study from the National Renewable Energy Laboratory (NREL), showing a strong connection between EV ownership and solar adoption.

In a detailed examination of 869 households in the sunny San Francisco Bay Area, NREL’s research paints a clear picture: among those who have EVs, a significant 25% have also installed solar photovoltaic systems at home, compared to just 8% of those without electric cars. Interestingly, having solar panels also nudges homeowners towards buying EVs, though the effect is somewhat subtler.

So, what makes electric vehicles and solar systems such a perfect match? Shivam Sharda, NREL's computational research scientist and the paper's lead author, explains that EV enthusiasts might be eyeing solar as a way to balance their home charging costs. But the rewards extend further: the synergy isn't just about savings; it's also about developing a more stable and efficient energy grid.

Another key aspect of the study is the power of social influence. “If you have a friend or a family member who owns a rooftop solar panel or an EV, you become more educated about the technology, so you know the pros and cons by talking to them,” Sharda said. “That has a significant influence on your owning EVs or PVs.”

The research points to the idea that policies encouraging the joint adoption of EVs and solar panels could fast-track the transition to sustainable technologies. This seems especially relevant for EV owners, who are already inclined to go solar, potentially leading to a swifter adoption of green tech solutions.
