Description

Editor-in-Chief of Embedded Computing Design, Brandon Lewis, unpacks the Indoor/Outdoor e-peas Solar Development Kit

 

The Indoor/Outdoor e-peas Solar Development Kit (AEM-PF-EVK) makes integrating indoor solar into electronics simple. It includes e-peas high-performance energy harvesting PMIC with integrated power management designed and optimized for PowerFilm’s thin-film indoor and outdoor solar panels.

 

The AEM-PF-EVK efficiently extracts energy from the solar modules, which can be stored in a rechargeable element while also providing two independent regulated voltages to power IoT devices. The integrated power management supports multiple storage element charge configurations, including, Li-Po, Li-ion, LiFePO4, Solid State, and Single/Double cell supercapacitors. Configurations are easily selected by moving pin jumpers to desired positions. 

 

Harvesting indoor light with the paired LL200-2.4-37 panel provides approximately 80 µW in a low light luminosity (200 lux). After 8 hours of exposure, the AEM10941 harvester will collect about 1.8 J of energy.

 

Harvesting outdoor light with the paired  MPT2.4-21 panel provides approximately 6.8 mW under indirect or ambient sunlight (25% of direct sunlight). After 8 hours of exposure, the AEM10941 harvester will collect about 156 J of energy.
