Loading vaccine refrigerator and phase change material at Hai Phong port

Traditional solar refrigerator systems use batteries to store the sun’s energy for the night and cloudy periods. However, problems with battery maintenance have made solar refrigeration a challenge in many low-resource settings. To address the battery problem, refrigerator manufacturers have created a new category of solar refrigeration that eliminates the need for an energy-storage battery. Vietnam has piloted this battery-free solar refrigeration system to evaluate it as a vaccine storage solution, especially in areas where electricity is limited.
