[RE-wrenches] Off Grid Refrigeration

[Steve McCarney]

Hi Drake

Probably the biggest development in off grid solar refrigeration is the
growing use of battery free solar direct drive (SDD) fridges and freezers.
These are now in widespread use by the global immunization community for
vaccine refrigeration and some ice pack freezing.  It is believed there are
over 10,000 already deployed with many more planned in the next few years.

There are 7 manufacturers around the globe that have earned WHO
"pre-qualification" after passing stringent testing focused on conserving
vaccine.  Some also offer SDD for other uses.  To see who they are go the
WHO website and see their catalog with approved fridges and freezers at
http://apps.who.int/immunization_standards/vaccine_quality/pqs_catalogue/

Best wishes

Steve McCarney, Director of Cold Chain Solutions, Solar Electric Light Fund
