UR-SolarCap: An Open Source Intelligent Auto-Wakeup Solar/Wind Energy Harvesting System for Supercapacitor based Energy Buffering  

We present and share a versatile design for an energy harvesting system that couples solar panels or wind turbines with supercapacitor buffers for storage. The system is an attractive option for powering computational systems deployed in "field settings" where power infrastructure is inaccessible. In these scenarios, supercapacitors offer a particularly compelling advantage over electrochemical batteries because of their ability to survive many more charge-discharge cycles.

We continue our research on energy harvesting and will make updates to this page as new publications and open resources become available.
