Solar Battery for Low-Power Devices

Sol Chip combines solar power with microchip technology to harvest light energy to power autonomous low-energy devices.

Sol Chip developed a maintenance-free solar battery and microchip acting as a low-powered Internet of Things communication module. With self-sustaining energy harvesting Sol Chip provides a continuous supply of energy, even when no light is available. Sol Chip’s integration of a solar-powered battery in the chip-manufacturing process reduces overall system operation costs by more than 60% compared to alternatives in the market and eliminates the need for battery replacements, according to the company. Sol Chip’s technology is being integrated into smart streetlights in Israel, where the aim is to give lamp posts their own IP address and the option to install motion sensors, pollution sensors, cameras, and more.

Relevance of solution

The Internet of Things has the potential to connect more than 20 billion “things” to the Internet by 2020.1 Sol Chip’s integrated solar power harvesting in miniature chips addresses the needs of remote or mobile devices that require autonomous operation, eliminating the need for new batteries and reducing environmental hazards and waste.

Triple Bottom Line


Using solar energy extends the life of IoT devices, limiting the need to continuously replace batteries and reducing the associated costs and waste.


The solution enables new technology integration in healthcare, for instance, by powering smart monitoring wristbands.


By allowing battery life extension or battery elimination in low-power applications, Sol Chip reduces companies’ operation and maintenance costs.
