Solar Refrigerator-Solar Freezer
If you have five hours of sunlight per day you can now have refrigeration.
One of the problems of OFF GRID living has been keeping perishable
Food fresh. Early Pioneers used many ingenious methods to cool there
Perishables. I was told as a child of a contraption called a springhouse.
A building was constructed of rock and cement. Water was diverted
down the walls. Burlap was placed in the doors and windows. The
children were assigned to keep the burlap wet. The evaporation cooled
the food 15 to 20 degrees lower than day time temperature. Milk would
last several days longer than sitting out warm.
Modern Day OFF GRID pioneers have many of the same problems
That faced the first pioneers. Now there is a solution to keeping food
Cool and fresh, the SOLAR FREEZER. Conventional freezers use
A single speed AC motor connected to a conventional compressor.
To use PV power a converter had to be placed in the circuit. This
Used a lot of the PV power and had limited functionality on cloudy
Days. One of the advantages of DC motors is there ability to be
Variable speed. If the sunlight is low the DC motor will steel turn.
If connected to a variable speed compressor some cooling takes
Place even when sunlight is low.

combine state of the art Electronics and new refrigerants, which has
no Freon. The solar refrigerator’s thermal storage material provides
7 days of backup cold storage. the unit can to run on as little as 80
to 120 watts of PV power and can be either 12 or 24 DC volts.
