Power Without Plug or Battery
We don’t often think about the moments when technology fails. A sensor that goes dark. A digital price tag that needs a battery replaced. A dead remote in a meeting room. But all these small power gaps add up to bigger inconvenience, lost time, high maintenance costs, and growing piles of batteries we’re still not recycling enough
In the beginning of Epishine’s journey we asked a simple question:
What if devices could continuously power themselves from the light that’s already around them?
A New Kind of Solar
Traditional solar is built for rooftops and open fields where there’s plenty of light and no need to adapt to indoor environments. Epishine’s solar cells are built for indoors, to quietly capture energy from surrounding light like LEDs or indirect sunlight. They are thin, flexible, ultra-light, and designed to fit into devices where batteries once ruled.
Our indoor solar cells are:
- Optimized for low-light performance
- Thin and flexible, easy to integrate in small electronics
- Durable and stable, even in challenging indoor environments
- Available in multiple sizes and formats, ready for integration
What It Powers
Epishine’s indoor solar cells are designed to power the kind of devices that quietly run our world, especially the small, smart electronics that make up the backbone of today’s connected environments.
Our technology is already enabling a wide range of low-power devices that operates without batteries or charging, including:
- Electronic shelf labels in retail environments, which need constant updates and long runtimes
- Asset tracking tags in warehouses and logistics systems, where maintenance access is limited
- Environmental sensors that monitor air quality, temperature, or occupancy in smart buildings where down-time could be critical
- Consumer and commercial electronics where seamless, maintenance-free power adds both convenience and sustainability
These are products that usually rely on small batteries, and in large deployments, those batteries add cost, complexity, and environmental burden. With Epishine’s indoor solar, these devices can run continuously using the light that’s already in the room. No disposable batteries needed.
It’s a small change with massive ripple effects: fewer service calls, longer lifespans, lower total cost of ownership, easier freight, user convenience and smarter systems that just work.
Designed for Integration
We work closely with product developers to make solar integration as easy as possible; we offer design support, technical documentation, and a growing set of developer tools.
No solar expertise required. Just the vision to build smarter and better.
