A solar-powered refrigerator or solar powered fridge is a refrigerator/ fridge which runs on electrical energy directly from the sun (DC/ direct current), and is typically powered by photovoltaic (solar panels).
In addition to photovoltaics, they typically require a battery bank for storage of electrical energy to keep the solar refrigerator running during nighttime or cloudy days. A solar charge controller/ solar electric regulator helps to protect the system and regulate the electric charge from the battery bank and solar panels.
Solar-powered refrigerators or fridges are able to keep perishable goods such as meat and dairy cool and are used to keep much needed vaccines at their appropriate temperature to avoid spoilage. These products are available in a chest or upright styles.
