Lenovo has introduced a groundbreaking concept laptop at Mobile World Congress, the Yoga Solar PC, designed to encourage outdoor work by reducing reliance on power cables. This innovative device features a solar panel integrated into its lid, capable of absorbing light from any source to extend battery life.
The Yoga Solar PC is an early proof-of-concept device that leverages 84 solar cells with a Back Contact cell design, allowing for over 24 percent conversion efficiency. This means it can absorb and convert enough sunlight in 20 minutes to power up to one hour of video playback. While this efficiency surpasses many silicon-based solar panels used in consumer electronics, it still lags behind cutting-edge perovskite-enhanced panels, which can achieve up to 43 percent efficiency. Lenovo is still testing performance under lower-light conditions.
Powered by Intel’s Lunar Lake processor, the Yoga Solar PC comes with 32GB of RAM, a 1TB SSD, and a 14-inch OLED display. The laptop is designed to be thin and lightweight, measuring just 15 millimeters thick and weighing approximately 2.29 pounds. It also features Lenovo’s Dynamic Solar Tracking System, which monitors solar power generation to help users optimize charging.
For current Yoga users, Lenovo also showcased an external Solar Power Kit, a foldable, portable solar panel that can charge devices via USB-C or store energy in an included power bank. However, like the Yoga Solar PC, there are no confirmed production plans yet.
While solar power alone may not fully replace traditional charging, Lenovo’s concept bridges functionality and environmental awareness, offering an alternative energy source for users who work remotely or in unpredictable environments.
Whether the Yoga Solar PC reaches consumers remains to be seen, but it signals a promising shift toward more sustainable computing solutions.
