Amazfit Puts Solar Charging on a Smartwatch AMOLED Screen With T-Rex Dual Solar

Wearable maker Amazfit has unveiled the T-Rex Dual Solar, a rugged smartwatch it says is the first to pair a solar-charging layer with an AMOLED display, with photovoltaic material on both the front of the screen and the rear of the case. The dual-panel approach is designed to extend battery life by topping up the watch’s charge from ambient light — the same photovoltaic principle, miniaturized, that underpins the utility-scale solar industry.

While consumer wearables represent a tiny slice of solar demand, the launch is a reminder of how photovoltaic (PV) technology — semiconductors that convert sunlight directly into electricity — continues to spread beyond rooftop panels and solar farms into everyday electronics. PV solar modules remain dominated by industrial manufacturers such as First Solar, which produces thin-film solar modules for utility-scale projects across the United States, India, Chile, France, and other markets.

Shares of First Solar closed at $203.10, down 4.85% from the prior close of $213.45, valuing the company at roughly $23.1 billion. The solar manufacturer operates in the technology sector’s solar industry segment, selling thin-film PV modules built on its proprietary semiconductor technology.

Small-scale solar in consumer devices

Solar assist charging has appeared on a handful of outdoor watches before, typically as a ring of small cells around the display. Amazfit’s claim of a first relates specifically to combining solar input with a full AMOLED screen — a display type prized for color and brightness but generally more power-hungry than the low-resolution memory-in-pixel panels common in solar-equipped sports watches. Capturing light on both the front and back of the device adds another charging surface, useful for a watch worn screen-down or resting on gear.

Amazfit has positioned the T-Rex line for outdoor use, with durability features aimed at hikers and field workers. The company did not announce utility-sector applications, and the wattage involved is orders of magnitude below grid-scale generation.

For the broader solar industry, consumer-device integrations remain a niche. Utility-scale PV demand — driven by power-purchase agreements, data-center electricity growth, and domestic manufacturing incentives — continues to set the sector’s financial tone, as reflected in the trading of publicly listed module makers like First Solar.

What to watch

• First Solar’s upcoming quarterly earnings report and any updates to full-year module shipment and revenue guidance.
• Announcements on new manufacturing capacity or module orders for thin-film PV technology.
• Amazfit’s pricing and availability details for the T-Rex Dual Solar, and independent battery-life testing of the dual solar charging claim.
