Solar charging comes to the wrist: a first look at the world’s first solar AMOLED sports watch
A wearable that pairs solar charging with an AMOLED display has landed, and ZDNET recently went hands-on with what is being described as the first sports watch to combine the two technologies. The review focuses on a long-standing engineering tension: AMOLED screens, prized for their contrast and color, are typically power-hungry, while solar cells on a watch face have historically forced makers to compromise display quality.
According to the review, the device integrates photovoltaic capability directly into the watch design, allowing ambient light to supplement battery charging during everyday wear and outdoor activity. The core question the testing addresses is practical: how much does solar input actually extend the charging cycle, and how does the watch manage the power demands of a bright AMOLED panel?
While the product itself sits in the consumer electronics space, it draws on the same underlying photovoltaic (PV) technology — materials that convert sunlight directly into electricity — that powers the utility-scale solar industry, albeit at a vastly different scale and efficiency tier. Small-format PV in wearables remains a niche application compared with the utility and commercial installations that dominate global solar deployment.
Broader solar market context
The mainstreaming of solar into consumer devices arrives as large solar manufacturers navigate a choppy public-market stretch. First Solar (FSLR), one of the largest US-based PV module makers, traded at $203.10 recently, down 4.85% from its previous close of $213.45, with a market capitalization of roughly $23.1 billion. First Solar manufactures thin-film solar modules for utility-scale projects across the United States, India, France, Chile, and other international markets.
The contrast illustrates the breadth of the solar supply chain today: from gigawatt-scale module manufacturing feeding power grids, down to miniature cells flexible enough to sit behind or around a curved smartwatch display. Each application places different demands on cell efficiency, durability, and cost.
Why display-plus-solar matters
For wearables, the appeal is straightforward — reduced dependence on wall charging, particularly for athletes and outdoor users who wear a watch for days at a time. The trade-off, as the ZDNET testing explores, is whether solar top-ups are meaningful enough to change user behavior, or simply a supplementary feature. Performance will hinge on factors such as panel area, light conditions, and how aggressively the display manages its own power draw.
