Such a fridge would open at the top, instead of at the front. The cool air is heavier and this way of opening the fridge reduces energy consumption. | Such a fridge would open at the top, instead of at the front.

The LOW←TECH MAGAZINE article mentions: "A study of direct solar refrigerators in very sunny regions (Texas and New Mexico, USA) showed that they maintained their cooling capacity for 6 or 7 days without power supply. The units operated year-round with solar panels of only 80W to 120W."<ref>Ewert, M., et al. “Photovoltaic direct drive, battery-free solar refrigerator field test results.” Proceedings of the solar conference.
