energy harvesting

AIoT energy harvesting solution

The solar box, Arc-solar, is an energy harvesting device for LPWAN/4G(Gateway) IoT with no angle limitation that we can collect scattered light very efficiently. In a sunny day, the solar energy we provide is more than an AAA battery. 

Just like Iron man’s power source Arc reactor, Flexwave’s Arc-solar is a solar energy harvester of IoT devices. The lifetime is 10 years so that let battery free and help companies be more economical.


High performance

with the specialized developing solar power management system, there is more 40% energy harvesting into the battery.

UV protection & Waterproof

Using durable PC materials and Flexwave's patented waveguide packaging technology, our Arc-solar box is capital of protection against uv rays and waterproof. It's not yellowing after being at outside for a long time.

10 years lifetime

Lifetime is up to ten years. Our Arc-solar box sustainably provides solar energy harvesting to collect data without interrupted.

Battery free

Because of the excellent solar charge controller, our arc-solar box is available of self-powered with rechargeable battery. No maintenance should be paid.

Plug & play

Providing all accessories needed for solar energy harvesting. You just plug & play.
