These guys sell some solar equipment as well as low energy and other off-grid technology freezers, fridges, and so on. They seem reasonably cheap.

SunDanzer make a few low energy refrigerators and freezers as well as some more wacky refrigeration stuff. They make the DDR165 which can be hooked directly to a solar panel bypassing the need for batteries and other equipment. Very cool. Around $1000.
