Energy Harvesting Controls for Solar Direct-Drive Cooling Systems: A Laboratory Testing Report

Photovoltaic power generation (solar panels) can be a useful means to power equipment essential to storing, delivering, and supplying vaccines in settings where mains power is not available or is unreliable. This report presents the methods and findings from laboratory testing of two energy harvesting control (EHC) prototypes with three different solar direct–drive refrigerators prequalified by the World Health Organization's Performance, Quality and Safety team. The primary goals of the testing were to inform potential specifications for EHCs, test the specific prototypes, and collect data to answer a number of questions raised by the possible introduction of EHCs to vaccine cold chain systems.
