Nissan has unveiled an innovative solar power system designed to extend electric vehicle range, reduce reliance on grid charging, and enhance user convenience for daily commuters.
The prototype, named the Ao-Solar Extender, was showcased at the Japan Mobility Show. It was demonstrated on the Nissan Sakura, an electric “kei car” that has been Japan’s best-selling EV for the past three years.
The system mounts on the vehicle’s roof, allowing it to charge the battery whether the car is driving or parked.
It incorporates a fixed panel that continuously captures solar energy and an additional, extendable panel. This retractable element significantly increases the energy capture surface, boosting power generation up to approximately 500 watts.
The extendable panel also provides shade for the cabin, which helps reduce the interior temperature by limiting light entering through the windshield. This feature can decrease the need for air conditioning.
Nissan estimates the Ao-Solar Extender could generate enough energy to support up to 3,000 kilometers (approximately 1,864 miles) of additional range annually.
This substantial range extension could virtually eliminate the need for traditional grid charging for many users, particularly those who primarily make short daily trips such as school runs or grocery shopping.
The system’s design prioritizes aesthetics and aerodynamics, integrating harmoniously with the Nissan Sakura’s existing structure to minimize wind resistance.
The Ao-Solar Extender concept aligns with the second pillar of Nissan’s “Re:Nissan” strategy, which focuses on delivering innovative mobility solutions to improve customer experience. It also strengthens the brand’s position in Japan’s competitive kei car segment.
Beyond its daily charging benefits, the system is envisioned to function as an emergency power source during natural disasters. The idea for the Ao-Solar Extender originated from an internal Nissan ideas contest held in 2021.
Nissan plans for a commercial launch of the system in the future, with specific dates to be announced later.
