What is a solar cooler

Solar coolers sound futuristic, but they’re here to stay. What is a solar cooler? How can it be used? We’ll be looking at this unique product in this article. 

A solar cooler is a portable container designed to harness the sunlight to cool your food and drinks. It runs on a compact refrigeration system that is connected to solar panels.

This is clean and free solar energy you can use anywhere.

The solar cooler collects solar energy through the solar panel, stores its power bank, and then sends this energy to the cooler’s refrigeration system.

Who needs a solar cooler?

  • Solar coolers are great for beachgoers, RV owners, campers, boaters, fishers, and backyard parties. 


  • For people living in off-the-grid locations without AC power, or for folks in places where electricity is unreliable. You don’t have to worry about your food going bad after power cuts ever again.


  • For emergency preparedness people. During natural disasters like floods and hurricanes, power is likely to go off for a couple of days. Harnessing solar to cool your food and drinks during time is smart. 

Why you need it

A solar cooler offers the easiest way to keep your food and drinks fresh while being outside your home. 

If you’re someone who enjoys the outdoors, you will understand how ineffective regular ice-filled coolers are. The ice melts, and everything becomes soggy after a couple of hours. 

However, a solar cooler can keep your food cold at temperatures as low as -4°F without an electric outlet for 24 hours. And because the temperature can be adjusted, solar coolers provide more value to users. 

They also come in rugged designs that make them durable for parties and trips. Solar coolers don’t need cooling packs or ice, so this means more space for you to store your food and drinks. You don’t have to bother about replenishing your ice supply every other hour.

Of course, solar coolers don’t need fuel, gas, or AC power. They produce no waste or carbon dioxide. 

The best solar coolers come with handles that make them portable. Asides keeping your beer or wine cold for the party, a solar cooler can even be used to preserve medicine while traveling to remote regions with no access to electricity.
