SolarChill – a solar PV refrigerator without battery

Solar Chill

Solar Chill

This is a refrigeration unit made primarily for storing vaccines in 3rd world countries where it is difficult to find refrigeration units to keep the vaccines chilled.

SolarChill still costs about $1500 but it is expected that the price will drop as the technology advances.

It works by generating ice in the daytime while solar is available and then using the ice for cooling at night.  This means you don’t need a battery to store energy.

It can also run off of other energy sources such as wind or from energy off of the grid.

Can’t wait until we can all have these.

The patent has been made public.  Here is a document describing how it works.
