Nissan has introduced the ‘Ao-Solar Extender’, an extendable, roof-mounted solar system designed for the Nissan Sakura Kei EV, capable of generating solar power for up to 3,000 km of annual driving. The system will be showcased at the Japan Mobility Show 2025.
Key Takeaways
- Roof-mounted solar system extends EV driving range by up to 3,000 km annually
- Developed in-house to reduce grid reliance and simplify EV charging
- Solar panels operate while driving or parked, generating up to 500 Watts
- Part of Nissan’s Re:Nissan strategy to enhance sustainable mobility
- Commercial launch planned, with timing to be announced later
Innovative Solar Integration
Nissan’s Ao-Solar Extender represents a breakthrough in sustainable EV technology. Developed for Japan’s top-selling electric vehicle, the Nissan Sakura, the solar array integrates directly into the roofline to maintain aerodynamic efficiency. The fixed panel collects sunlight during motion, while a second extendable panel deploys when parked, increasing surface area for optimal solar capture.
Practical Benefits and Performance
The system can charge the vehicle on the go and when stationary. When extended, the solar module provides shade, reducing cabin temperature and lowering air conditioning power demand. Designed to blend with the Sakura’s styling, the lightweight array adds minimal drag while delivering meaningful range gains and charging convenience.
Impact on EV Ownership
By generating up to 3,000 km of solar power annually, the Ao-Solar Extender significantly cuts dependency on traditional charging infrastructure. For many Sakura owners, who drive short distances for errands or school runs, solar power could nearly eliminate the need for plug-in charging. Additionally, the system doubles as an emergency power source during disasters — a valuable feature in Japan’s preparedness-focused market.
Strategic Vision
The concept underscores Nissan’s Re:Nissan strategy, focusing on innovation, customer experience, and environmental stewardship. Integrating solar technology within the Kei segment demonstrates Nissan’s leadership in eco-friendly mobility and its commitment to shaping the future of EV ownership through practical, accessible solutions.
Showcase and Future Plans
The Ao-Solar Extender will be on display at the Japan Mobility Show 2025, featured in the Tokyo Future Tour “City Life Zone”, organized by the Japan Automobile Manufacturers Association (JAMA). The project originated from Nissan’s 2021 internal idea contest and is now being developed for future commercial release.
Bottom Line
With the Ao-Solar Extender, Nissan moves closer to energy-independent mobility, combining solar innovation and customer-focused design to redefine what’s possible for compact EVs in Japan and beyond.
