Since you failed to give any spiicfecs, this is a general idea of what is needed, assuming a standard home type refrigerator!1. take wattage of refrigerator, and add 50% to cover starting surge.2. buy inverter large enough to start and run fridge, and determine amperage required.3. buy enough batteries for inverter to handle a full 24 hours of running fridge, (measured in amp/hours)4. buy appropriate charge controller for batteries5. buy sufficient panels to generate at least twice, preferably 3 times, what is drawn from batteries to run inverter, since they only supply power during the daylight hours.NOTE: it will require MORE than a single panel to run ANY large appliance.
