Photovoltaic vaccine refrigeration at Centro De Salud. This photovoltaic system was designed to power a DC Vaccine Refrigerator at the hospital Centro De Salud in Parras, Mexico. Centro De Salud had a list of items that needed to be purchased at their hospital. Among these was a new vaccine refrigerator. After learning of this, the project group members set out to design a PV system for the hospital that could fulfill this need.

PV systems are well suited for vaccine refrigeration for a few reasons. PV arrays are becoming an increasingly popular alternative to gas generators for supplying energy to off-grid vaccine refrigeration because of their ability to create reliable energy that requires little system maintenance. LINK PDF According to the World Health Organization, PV refrigeration systems are much more efficient at maintaining internal temperatures in refrigerators than gas generators. This creates for an overall greater reliability of the refrigerator system. In the case of Centro De Salud, having a PV powered vaccine refrigerator could prevent vaccine spoilage due to grid power outages, which can be very costly.
