Aligning electric vehicle charging with the sun: An opportunity for daytime charging?

Recent studies show how a strategic shift towards daytime charging of electric vehicles (EVs) has the potential to be a powerful game-changer, leveraging flexible EV loads to maintain solar value on the grid and aligning EV charging energy load with solar generation. Also, recent studies show the benefits of expanding investment in daytime charging infrastructure and reforming time-of-use rates to promote daytime charging. By harmonizing energy consumption patterns with solar supply, we can increase the solar industry's economic appeal and sustain its growth trajectory while potentially reducing cost and improving convenience for charging vehicles that are parked during the day. This study integrates all these different studies and provides a comprehensive perspective on the benefits, challenges, and barriers to implementing daytime EV charging at scale. © 2025 The Authors
