In a bold move toward self-sustaining electric mobility, Nissan has unveiled a prototype of the ‘Ao-Solar Extender’, an innovative onboard solar power generation system installed on its best-selling electric vehicle, the Nissan Sakura, at the Japan Mobility Show 2025.
Developed entirely in-house, the Ao-Solar Extender aims to reduce dependence on conventional charging infrastructure by allowing the vehicle to generate its own electricity. According to Nissan engineers, the system can produce enough solar energy annually to power up to 3,000 kilometers of driving, highlighting the automaker’s ambition to make EV ownership more convenient, efficient, and eco-friendly.
The concept embodies the second pillar of Nissan’s Re:Nissan strategy, which emphasizes innovation and customer-centric mobility solutions. Designed to enhance the everyday practicality of EVs, the solar system can charge the vehicle both while driving and when parked. When stationary, an additional extendable solar panel deploys from storage, increasing power generation capacity to around 500 watts while also shading the cabin to reduce air conditioning load and energy consumption.
Aesthetically integrated into the Sakura’s design, the system minimizes drag and performs effectively under varying weather conditions — from bright sunlight to light rain. Data from existing Sakura owners suggest that for many urban drivers, who typically cover short distances daily, this solar integration could nearly eliminate the need for grid-based charging. The system also doubles as an emergency power source during natural disasters, offering an added layer of resilience.
The Ao-Solar Extender will be showcased in the “City Life” zone of the Tokyo Future Tour, coordinated by the Japan Automobile Manufacturers Association (JAMA). Originating from a 2021 Nissan internal innovation contest, the project has now evolved into a near-commercial prototype, with launch details to be announced later.
By merging solar energy with EV technology, Nissan reinforces its position as a pioneer in sustainable, intelligent mobility, aligning its vision with a cleaner, self-reliant future for everyday drivers.
