Solar-Powered Refrigeration: "Designed to function in arid to semi-arid regions with at least 5 sun-hours per day, the PV direct-drive, or “PV direct,” SunDanzer™ solar refrigerator is a chest-type cabinet with a 105-liter (3.7 cubic feet) internal volume, a lockable top-opening door, a corrosion-resistant coated steel exterior, and a patented low-frost system. It uses thermal storage for cooling efficiency, with a direct connection between the vapor compression cooling system and the PV module. This is accomplished by integrating a phase-change material into a well-insulated refrigerator cabinet and developing a microprocessor-based control system that permits the direct connection of a PV module to a variable-speed compressor. The integration allows for peak power-point tracking and the elimination of batteries.. The solar refrigerator's thermal storage material provides 7 days of reserve cold storage, even in tropical climates, or during extensive periods of cloudy weather .. Light indicators on the front of the refrigerator inform users of the status of the thermal reserve.

For frequently cloudy regions or areas with less than 5 sun-hours per day, SunDanze Refrigeration offers highly efficient battery-powered refrigerators, as well as freezers. These units run on 12 or 24 volts, direct current, and require a smaller PV or renewable energy system. "  Current retail price $900.
