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

As of: December 2020

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, which operates without refrigerants that are harmful to the climate.
  • Several training courses carried out in Eswatini and Germany (e.g. on welding aluminium microchannel evaporator tubes)
  • Two types of solar refrigerators developed and marketed (around 400 during the project term)
  • Several workshops were carried out in Eswatini and Germany in cooperation with the project's partner focusing on redesigning the systems
  • Technology presented at various international Forums
  • In order to test the vaccine coolers in the field, contact was made with rural health clinics in Kenya, and the idea of a mobile application linking parents and nursing staff was born.This has resulted in the app "emmunize" (see link), which is supported and developed by the GIZ internal innovation fund. www.emmunize.org
