The light harvester development board is here!

The full micro-panel delivers about 5V @ 10uA = 50 uW on a cloudy day behind a dual-pane window.

The same panel delivers 10V @ 1mA = 100mW on an average sunny day outdoors.

This means a 3V @ 100mA (300mW) battery can be fully re-charged in a few days of sunny exposure, or maintained at a state of charge in a normal office environment.

A lot more work needs to be done to properly design a circuitry to accommodate partial shading and dark current, however, so far the powerplant basic premise is a total success!
