Solar Chill: Deploying Solar-Powered Environmentally Sound Freezers and Refrigerators in Off-Grid Areas

As of: July 2020

Objective and activities

Reliable cooling is essential for the shelf life of food and vaccines, but in tropical and subtropical climates, it is either not always guaranteed, or is achieved by appliances using climate-damaging refrigerants, insulating foams and batteries containing heavy metals. The SolarChill project develops solar-powered, environmentally friendly cooling devices that are affordable for the local population. The solar refrigerators are adapted to the climatic conditions in southern Africa and can cool food and vaccines for several days without being connected to the power grid. Around 400 devices are to be manufactured locally and delivered during the term of the project.

State of implementation/results

  • Solar-powered vaccine refrigerator developed and manufactured (MC72), which operates without climate-wrecking refrigerants
  • Several training courses carried out in Swaziland and Germany (e.g. on welding aluminium microchannel evaporator tubes)
  • Two types of solar refrigerators developed and marketed (around 400 during the project term)
  • Agreement concluded with The Fridge Factory (TFF) to cooperate on the further development of the vaccine refrigerator (MC72 to MC100); tested successfully by the Danish Technology Institute according to WHO criteria; technology to be transferred to commercial and household appliances
  • Several workshops carried out in Swaziland and Germany in cooperation with the project's partner focusing on redesigning the systems
  • Technology presented at various international Forums
  • Development and production of solar-powered refrigerators in cooperation with the partner Palfridge in South Africa
  • In order to test the vaccine coolers in the field, contact was made with rural clinics in Kenya
  • As part of the GIZ Innovation Fund 2018 the project team develops the the application "emmunize". It complements the vaccination cooling system with a software to increase immunization rates in remote areas.
