solar powered refrigerator

Personally,I am glad to see people is actually thinking about how to use solar panels in to our life.From the picture design ,we can only see one solar panel is mounted on the frame of the refrigerator.I highly doubt that it is enough to power the whole refrigerator  as it requires a lot of electric power.There is a 12V 100Ah battery in the base of the refrigerator to make sure the freezer can work 24hours.They also claim that this freezer is able to maintain temperatures down to minus 20 degrees Celsius.
