    Question about solar refrigeration

    Hi
    I have a small solar set up (770 watts) and I'm looking at how to have some sort of refrigeration.
    I'm look at a refrigerators that are for solar application. There a little pricey but I figure I only need
    to pay for it once. I have had a few people tell that I would be better off using a small freezer chest
    and converting it to a refrigerator. I have had a few people say that it will take about the same
    amount of power to run. I don't know but that just doesn't sound right.
    I would like some input on this.

      it is common to take a chest freezer, put a different thermostat in it and use it as a chest fridge.

      The cold air does not fall out when it is opened, it is thought to be a cheaper alternative to a an energy efficient fridge, but not as convenient to use.

      Saying that your system is 770w does not really mean much, you will need to list your panel and battery specs, current usage and where you live to allow someone to give you an idea of what power you have available therefore what refrigeration you can add to the system.

          Thanks for the reply but my question is when a small freezer is converted to a refrigerator how
          does it compare to a refrigerator made for solar use far as how much power it uses?

              A little more or a little less. You give nothing to compare.

                  I dont think of a fridge made for solar use, rather a very energy efficient fridge is better suited for solar use.

                  But very energy efficient fridges will generally be very expensive compared to a converted chest freezer.

                  I have an expensive type fridge so dont have power consumption figures for a converted freezer but unless we lived in the same climate and had the same usage pattern then the figures would be meaning less anyway.

                  I think it really the price factor that makes people go with the freezer conversion. If you can afford a suitable fridge then they are much more user friendly.
