At MWC 2025, Lenovo showcased an innovative and eco-friendly concept: the Yoga Solar PC Proof of Concept. This groundbreaking laptop features an integrated solar panel, which allows users to charge their devices outdoors without having to rely completely on traditional chargers.
But how much power can it harness? Well, the solar panel can actually add some juice to your battery. According to the company, the solar panel absorbs enough direct sunlight in 20 minutes to power up to one hour of video playback.
This particular setup runs on Intel’s “Lunar Lake” Core Ultra 200 platform. So a future consumer PC with a Snapdragon SoC could potentially run even longer with a similar solar cell.
Alongside the laptop, Lenovo also introduced a Yoga Solar PC kit, a portable solar charging solution compatible with any USB-C device. The panel is remarkably thin at 15 mm, and the entire laptop weighs just 1.5 kg, making it portable and practical for outdoor use.
How it works
The Yoga Solar PC Proof of Concept features a solar panel that can charge the laptop both during use and when idle. The solar panel leverages Back Contact Cell technology, which moves mounting brackets and grid lines to the back of the solar cells, increasing efficiency to 24%—higher than the 19-20% efficiency of most commercially available solar cells. Additionally, the Dynamic Solar Tracking system optimizes energy absorption by adjusting the panel’s settings based on sunlight intensity.
While people generally do not work outdoors in direct sunlight or leave their PC in that situation, this proof of concept will at least allow you to stay connected when the power grid is not active or when you’re outside.
The prototype in the venue was in black, but the company seems to be experimenting with different colors too before commerical release.
Lenovo has not yet announced pricing or availability for the Yoga Solar PC Proof of Concept.
