Of all the appliances in a typical home, the refrigerator and freezer rank the highest in terms of electricity requirements. But what if you could replace the conventional fridge with one that fulfills the same functions for free? That’s exactly what a solar powered refrigerator can do for you.
At present, most fridges that work on solar power are relatively small and not necessarily suitable to replace their more traditional counterparts in an average-sized home. However, they make perfect additions to any off-grid boat, RV, cabin, and more.
What Are the Best Solar Powered Refrigerators in 2019?
The hallmarks of a good solar powered refrigerator include durability, efficiency, and the ability to double as a freezer in order to save space. All items on the following list meet these requirements and have additional useful features to boot.
