The Chinese tech company Lenovo recently unveiled a prototype of the ultra-slim Yoga Solar PC laptop at the Mobile World Congress (MWC) 2025, the annual tech trade show in Barcelona. With integrated solar panels on the concept laptop's top panel, solar energy is used for extended battery life.
The Yoga Solar PC features 84 solar cells integrated into the laptop's lid, achieving a solar energy conversion rate of over 24%. This efficiency enables the device to convert 20 minutes of direct sunlight into approximately one hour of video playback. Lenovo's proprietary Dynamic Solar Tracking system optimizes energy absorption by continually monitoring current and voltage adjusting settings to maximize efficiency.
Despite its advanced solar technology, the Yoga Solar PC maintains a slim profile, measuring just 15mm in thickness and weighing 1.22 kilograms. It boasts a 14-inch OLED display and is powered by Intel's high-efficiency Lunar Lake Core Ultra 200 platform, complemented by 32GB of RAM.
Currently, the Yoga Solar PC is a proof-of-concept with no immediate plans for commercial release. However, its introduction highlights Lenovo's commitment to integrating renewable energy solutions into consumer electronics, potentially reducing reliance on traditional power sources.
The concept has garnered attention for its potential to revolutionize mobile computing. By enabling users to recharge their devices using ambient light, Lenovo addresses both convenience and environmental concerns, paving the way for more sustainable tech solutions. Lenovo's Yoga Solar PC exemplifies the possibilities at the intersection of technology and sustainability, offering a glimpse into a future where devices are not only smarter but also more eco-friendly.
ThinkBook, another concept laptop featured at MWC, boasts a flexible display that folds out vertically, doubling the length of the screen. These both follow Lenovo's recent announcement of its "rollable" laptop at the Consumer Electronics Show in Las Vegas earlier this year.
