At MWC 2025 in Barcelona (Spain), Lenovo introduced an impressive new idea, a laptop powered by solar energy.
Called Yoga Solar PC, this Lenovo product is equipped with a high-efficiency solar panel that can convert up to 24% of energy, equivalent to the best solar panels currently on the market. According to information from Lenovo, with just 20 minutes of direct sunlight exposure, users can use the computer to watch videos for 1 hour.
Equipped with solar panels, the Yoga Solar PC still ensures a thin and light design.
Even in low light conditions, the solar panel can still generate enough energy to maintain the battery charge when the device is idle. “Back Contact Cell” technology and advanced tracking system optimize the device’s energy saving and stability.
What's special is that, despite being equipped with a solar panel, this laptop still maintains a thin and light design with a thickness of only 15mm and a weight of 1.22kg, making it the world's first ultra-thin solar-powered PC. Lenovo plans to equip this product with an Intel Core Ultra CPU, up to 32GB of RAM, 1TB of storage, and an OLED display. Other specifications include a 50.2Wh battery, a 2M IR camera, 4 speakers and microphone, and 3 USB-C ports.
The conversion efficiency of the solar panel is the best available.
Lenovo also showed off a portable solar panel and power bank that lets users charge the battery by plugging the panel into USB-C and placing it anywhere there’s sunlight. This will be useful for those who want to use the Yoga Solar PC without sitting in direct sunlight.
While it’s unclear how much energy users will be able to harvest from the sun, any amount of energy counts. With this prototype, Lenovo has proven that it can build a solar-powered PC without sacrificing size, design, or specs.
Through the Yoga Solar PC, Lenovo has demonstrated its breakthrough in sustainable PCs.
However, the price of the product has not been announced yet, and the high price may affect the accessibility of consumers. Hopefully, Lenovo will bring this product to the market soon, which opens a new direction for sustainable computer technology.
