Looking for a solar-powered fan that strikes the perfect balance between versatility, portability, and cooling power? Take a look at these best solar fans out in the market.

Whether you need to cool off the attic, basement, or bedroom, camping in the great outdoors, fishing on a hot summer day, or need to cool off while watching your kid’s soccer game, there are different situations that require a good fan. 

Unfortunately, like most other gadgets and appliances, normal fans run on either electricity or batteries, meaning that they are more costly to use and maintain and have a negative impact on the environment. This is where a solar-powered fan comes in.

Solar fans have a plethora of benefits which we look at later in this guide. As expected, there are tons of solar-powered fans in the market, so it can be daunting to find the ideal one that ticks off everything you are looking for in a solar fan. 

Well, not to worry, because we went ahead and put together an all-inclusive guide with comprehensive reviews of the best solar fans, advantages of purchasing a solar fan, and what to look out for when buying one. So, let’s jump right in.

Types of Solar Fans

There is a wide range of different types of solar fans. Among them include:

1.    Solar Powered Attic Fans

The best solar-powered attic fan regulates an attic and the entire building’s heat levels by expelling out hot air, allowing cool air to come in. A solar attic fan is beneficial in many ways, including:

  • It is very effective. Research has it that a solar-powered attic fan can reduce attic temperatures by up to 50 percent. This means that the cooler the attic is, the cooler the whole building is. 
  • A solar attic fan significantly reduces the risk of ice damming on the eaves of the roof, which may cause damages to your roof, gutters, wall paint, to name a few. 
  • It prevents moisture build-up on your roof, making it last longer.

Typically, there are two types of solar-powered attic fans; a roof-mounted solar attic fan and a gable-mounted solar attic fan.

Roof-Mounted Solar Attic Fan

As the name suggests, this type of solar attic fan is mounted on the roof. Roof-mounted fans work by exhausting heated air, allowing cool air to flow in. 

Gable-Mounted Solar Attic Fan

Gable-mounted solar-powered attic fans are mounted behind existing louvered gable vents. They are suitable for barns, RVs, cabins, greenhouses, or places where moisture is likely to be present. This type of solar attic fan is installed and works differently from roof-mounted solar attic fans.

2.    Solar Power Outdoor Fans

Solar-powered outdoor fans are designed to enable you to enjoy the great outdoors while keeping yourself cool. They are lightweight and more compact, making them easily portable. This type of solar fan is perfect for camping, fishing, and other outdoor activities. 

3.    Solar-Powered Fans for Barns and Greenhouses

Solar fans for greenhouses are crafted to regulate the greenhouse temperature and enhance photosynthesis and pollination so the plants thrive.

Solar-powered fans for barns keep the barn cool, reduce moisture inside, and enable fresh air to flow in, therefore preserving the crops. 

4.    Solar-Powered Fans for Chicken Coops

You may not have realized it, but excess heat also makes chicken uncomfortable. Solar fans for chicken coops help keep the air inside cool, circulate air, provide extra ventilation, therefore, reducing the ammonia and moisture levels in the chicken coop. This keeps them comfortable and healthy.

Advantages of Solar Fans

While most solar fans, especially solar power ceiling fans and solar-powered attic fans are costly upfront, they have many advantages over traditional fans. Among these advantages include:

  • They are eco-friendly. Most people might not realize it, but fans that run on either batteries or electricity negatively impact the environment. 

For starters, when the batteries are disposed they release harmful metals like lead, cadmium, and mercury into the environment, causing water and soil pollution. On the other hand, those that use power from the electric power grid contribute to causing air and water pollution. 

Using a solar-powered fan helps reduce your energy consumption and environmental pollution, therefore reducing your carbon footprint. 

  • They are more affordable. Solar fans are cheaper than ordinary fans because they only run on renewable energy from the sun. According to research, using solar fans can help you save up to 30 percent on air conditioning costs. 
  • They are portable. A cordless solar fan provides much more mobility compared to normal fans. 
  • Using a solar-powered attic fan minimizes the amount of strain on your Heating, Ventilation, and Air Conditioning (HVAC) system, making it last longer.

What to Look out for Before Purchasing a Solar Powered Fan

To ensure that you buy the best solar fan that suits your needs, you have to keep in mind a couple of things. 

The Purpose of the Solar Fan

Before buying a solar fan, it’s important to ask yourself why you need it. There are different types of solar-powered fans, each designed for a specific purpose like cooling off the attic, cooling you off while you are outdoors or cooling the house. So, determining why you need to purchase a solar fan will help you pick out the right one that suits your needs. 


Now that you’ve figured out why you need a solar-powered fan, the next key aspect to consider is its size. If you require a solar fan to cool your house, a large fan would be the perfect one. On the other hand, if you need a solar power fan for camping, then a small one would be okay. 

However, it is essential to keep in mind that the larger the fan, the more power it needs. That is why it is important to place it where there is plenty of sunlight available. 

The Amount of Space it Needs to Cover

Another vital thing to keep in mind before purchasing a solar fan is how much space it is required to cover. So, if you need a fan that cools down a large room, it’s only best that you buy a large one with a higher CfM. Just ensure that the amount of space does not exceed the capacity of the solar fan.


This is an important factor, especially if you want to keep your solar fan with you. So, before buying one, make sure that it is lightweight and comes with features like handles for easier portability. 

Heat Vents

The main role of solar fans, especially solar-powered attic fans, is to expel heated air, allowing cool air to come in. During that process, it can collect a lot of heat that can cause some major damages to the fan if it is not released. This is where heat vents come in. 

Heat vents allow the heat to flow out easily, preventing the solar fan from overheating. So, before purchasing a solar-powered fan, make sure that it has enough vents.

Does it Need to be Installed?

Solar-powered fans, especially solar power ceiling fans, require to be installed. The process can be complicated, especially if you have never installed one before. That is why it is important to seek assistance from an expert if you have a solar fan that needs to be installed.


The Noise Levels

One of the major differences between solar fans and electric fans is that solar-powered fans run more quietly. While they make very little noise, some are louder than others. 

So, before purchasing a solar fan, check how loud it runs and see whether you will be comfortable with that noise. 

Frequently Asked Questions About Solar Powered Fans
