Lenovo introduced the Yoga Solar PC prototype at MWC 2025 in Barcelona, showcasing a potential future for solar-powered laptops.
The Yoga Solar PC features a high-efficiency solar module for direct sunlight charging, reducing reliance on traditional power outlets.
Initial tests suggest 20 minutes of solar exposure can generate enough power for one hour of video playback.
It uses Back Contact Cell technology, placing electrical contacts on the cell's rear to maximize light exposure and energy absorption.
An energy optimization system constantly monitors panel current and voltage, automatically adjusting charging settings.
The system can extend laptop autonomy and maintain battery charge in standby mode under low light.
The prototype is compact (15mm thick) and lightweight (1.22 kg).
It includes a 14-inch OLED display and supports Intel Core Ultra processors, up to 32GB RAM, and a 1TB SSD.
Solar panels can capture ambient light, potentially adding an hour of use to an eight-hour workday.
