Nissan said that drivers in sunny areas could reduce their charging frequency by up to 65%.AdvertisementAdvertisementThe solar-powered EV is a joint project between Nissan and Lightyear, which supplied the panels covering roughly 41 square feet above the cars.The concept is simple but striking. Solar cells built into the car help top off the battery without the need to plug in, potentially adding range while reducing the time needed to intentionally refuel the car.The Ariya also isn't the only EV to include a solar roof. The company showcased the Sakura, which also includes a rooftop solar charging system called the Ao-Solar Extender. The Sakura with the rooftop charging array was unveiled at the 2025 Japan Mobility Show, where Nissan said that it could add nearly 1,900 extra miles of range annually.The company is presenting this technology as a way to make EV charging more convenient, especially for commuters or anyone who leaves their car parked outside for long stretches of the day. For many people, that is the big selling point: free energy from the sun, with no charging cable required.Get TCD's free newsletters for easy tips, smart advice, and a chance to earn $5,000 toward home upgrades.
