How We Chose The Best Solar Refrigerator

In our search for the best solar refrigerators, we looked for elements like style options, energy efficiency, and ease of use.

Style Options

Solar appliances are not just for people who are trying to transition to an off-the-grid lifestyle. Many camping enthusiasts depend on solar power for things like cooking, charging their electronic devices, and keeping their food cold. That is why we looked for a variety of units, both stationary and portable, to show you the full range of what is available.

Energy Efficiency

Energy efficiency is paramount when it comes to solar-powered appliances, so we looked for stationary refrigerators with energy-efficient motors and compressors. We also looked for models that were well-insulated since more insulation means more consistent cooling with less energy use.

For the portable refrigerators, we looked for models that were energy-efficient enough to be used with any average solar power station. We also looked for models that were well built and well insulated, so they would require even less energy to maintain cold temperatures.

Ease of Use

As you would probably expect, most solar refrigerators are pretty straightforward. Simply connect them to a power source and they keep your food cold. That being said, we looked for stationary models that offer easy set-up with user-friendly installation instructions.

We also used specific criteria when looking at portable solar refrigerators. These fridges can be used at home, but in many cases, they will be used for camping which is why we looked for durable models that were designed to go with you on even your most off the road adventures. We also looked for multiple power options and wide temperature ranges because these features allow you to use a single unit for every situation instead of needing multiple units.

What You Need To Know About Solar Refrigerators

When looking for a solar refrigerator, there are a few key things that you should know before making your purchase.

Power Not Included

If you are new to the world of solar-powered appliances, it is important for you to know that unlike many smaller solar products, solar refrigerators do not usually come with a power source, meaning that the solar panels are not included.

There are a few simple reasons for this. Firstly, even though these refrigerators are designed to be super energy efficient, they still use quite a bit of electricity compared to other common solar products or lights or water pumps. This makes it difficult and costly for manufacturers to provide solar panels large enough to power a stationary refrigerator. Secondly, most people who are looking to purchase a solar refrigerator already have a solar system set-up in their home, so there would be no need for them to pay extra for solar panels they don’t need.

When it comes to portable solar refrigerators, these can easily be plugged into your portable solar power station or solar panels. Some manufacturers sell models that come with detachable solar panels that plug directly into the solar refrigerator, but this will increase the cost of the unit.

Solar Versus Propane

For those who are researching and comparing other off the grid refrigeration options, you may have run across propane refrigerators. Propane-powered refrigerators were the best off the grid option up until about 15 to 20 years ago because solar power technology was so expensive and inefficient.

Thankfully, solar power options have changed a lot over the last couple of decades. This has caused solar refrigerators to quickly overtake their propane-powered counterparts as the best option for off the grid homes. Propane-powered refrigerators are within a similar price range as solar-powered models, but they cost substantially more to run. The average propane refrigerator can cost up to $30 to $35 per month, making free solar power a much better option.

Beware The Extras

With many of the products we review, the extra features section just contains a few fun features that you may like. In the case of solar refrigeration, extras are not a good thing. Features like automatic defrost and ice makers can use a lot more energy than they are worth. When it comes to solar refrigeration, simplicity is your best choice.

Also, be conscientious when considering how much space you need in your refrigerator because extra space is not always a good thing either. More room in the fridge means more space that has to be cooled and there is no sense in wasting energy to cool space that you aren’t using. When choosing your solar refrigerator, be realistic about the amount of space you need so you don’t end up wasting energy.

How to Choose The Best Solar Refrigerator For You

Choosing the best solar refrigerator for you is a fairly simple process. The first step is to determine the style you need, then move on to power requirements.

Style

Choosing a style is pretty straight forward, but there are a few things you should know about each style to help you choose between models.

When it comes to stationary models, you have a few options to choose from, just as you would with a regular fridge. Do you need a freezer or just a refrigerator? Are you looking for an upright model or chest-style? If you do want a model that includes a freezer, choose one with the freezer on the top. Just as heat rises, cold air will drift down. The cold air from the freezer will settle into the fridge, helping to keep the refrigerator cold without the need for an extra fan to move the air.

Portable solar refrigerators are basically like coolers, but without the need for ice. They are compact and usually fairly easy to move. This is another situation where you can decide which model is best based on your preferences. If you do plan on traveling and carrying your solar fridge from place to place, you may want to choose a more lightweight model that has wheels and a sturdy handle. If you are traveling in an RV or just want to use your solar fridge at home, then you may want to choose a more heavy-duty model. These usually have a larger capacity but are heavier, making them less portable.

Power

Once you have determined the style you need, it’s time to talk about power again. If you have gotten to this portion of the article, you already know how important it is to look for an energy-efficient model, but here is a quick tip to help you do that. If you’re looking for a stationary solar refrigerator, just look at the EnergyGuide sticker. It should show the number of kWh that the unit uses per year. As long as that number is under 365 kWh, you should be able to run your refrigerator with approximately 1000 watts of solar modules, even with higher ambient temperatures.

Portable units are much easier when it comes to powering them because most models are 12/24v and are simple enough to plug into your solar power station. Just remember that they do not come with a power source, so plan ahead and make sure you have a proper power source available.

Bottom Line

Thank you for choosing solar power! Not only is it better for your budget, but it is better for the environment, meaning that every time you use solar energy you’re helping everyone. When it comes to refrigeration, solar power may not be the first thing that comes to mind, but thanks to many brands like Unique and Alpicool, it is now a feasible option.

Choosing the best solar refrigerator for you is as simple as choosing a style and then ensuring that you have the right power source to keep it going. If you already have a solar system in your home and want a permanent solar refrigerator, make sure you choose a simplistic model that uses less than 365 kWh per year. If you want a portable unit, just make sure you don’t forget to pack your solar power station when you’re loading up the camping gear.
