Introduction to Solar Attic Fans

The Cleaning King team knows that keeping your house cool and well ventilated is a big concern. The best solar attic fan is not just great for the hot summer months, you can also use it during winter.  

The colder months can bring mold and other issues into your home because of moisture build-up. A solar attic fan will help you with air circulation and ventilation to prevent this from happening. 

So what exactly are solar attic fans? Simply put, solar attic fans pull in the warm air from your attic and exchange it with the cold air from the outside.

They help to cool down the temperature inside your home so that you do not have to rely heavily on your air conditioning system. Solar attic fans use solar power, making them extremely energy efficient and budget friendly. 

A solar attic fan is easy to install and will not require any rewiring of your electrics or changes to the structure of your home. If you are hunting for an eco-friendly, cost-saving option to cool and ventilate your house, solar attic fans are a great option.

We at Cleaning King know that buying the best solar attic fan can be a challenge that is why we wrote this guide for you. We’ve created a comprehensive buying guide that will give you a bit more information about how to choose the best solar attic fan for your needs. We have also created a review of the 7 best solar attic fans on the market to get you started. 

Let’s take a look at the different types of solar attic fans currently on the market. 

Types of Solar Attic Fans

Some types of solar attic fans include:

Roof-Mounted

These types of solar attic fans need a vent hole in your roof. The fan is installed over the hole and sealed with shingle sheets. These types of fans are easy to install and are very energy efficient.  

You can purchase roof-mounted solar attic fans either as a standard or as hybrid models that offer the option of using electricity so you can still use them at night. 

Gable-Mounted

Gable-mounted solar attic fans are easier to install than roof-mounted ones. Just connect the wires, screw the unit into the gable, and the solar attic fan is ready for use. Some models come with electrical adapters that you can plug in so that you can use the fan at night.  

Portable

As the name suggests, you can take these types of solar attic fans anywhere. They are cheaper to purchase. The only disadvantage however is that they are not as powerful as the other types of fans available. 

 

How does a Solar Attic Fan work?

A solar attic fan uses solar power technology. The solar panels on these types of fans take energy from the sun and convert it into electricity that propels the movement of the fan.

Using solar energy, a solar powered attic fan can ventilate and cool down your roof and attic by taking hot air out of your space and pushing it out to the outside. This reduces overheating, moisture build-up and circulates fresh air throughout your home. 

Hot, humid environments not only breed bacteria, they also breed mold, which is very dangerous to people’s health. 

What are the Benefits of a Solar Attic Fan?

There are several benefits of purchasing and installing solar attic fans in your space. Because you can use them in all climates and seasons depending on the type you buy, the benefits of solar attic fans cannot be understated. These benefits include the following: 

  • They enhance the comfort of your home

An uncomfortable, hot and stuffy or extremely cold home is not what anyone aims for. If the temperature of your home is not ideal for you, purchasing a solar attic fan can improve the situation rapidly.

A home that is well ventilated and cool is a very comfortable home. Not only are you getting rid of unpleasant living conditions, you are also preventing other dangerous particles such as mold and bad smells from making an appearance in your home.

If you live in an area that experiences really harsh winters, you are unlikely to be opening your windows to let air in. A solar attic fan will be great in this situation because it will circulate the air inside your home regardless of what the weather is like outside. 

  • They Can Help Save Your Roof

Roof replacement is not cheap, so the longer you can stretch the lifespan of your roof, the better. Solar attic fans are great for roof preservation because they get rid of trapped moisture that causes rot, mold and mildew and ice damming that causes damage to the eaves of the roof.  

These unwanted conditions can cause a lot of damage to your roof. A solar attic fan will ventilate and circulate air in your attic and prevent excess heat buildup from the sun during summer and from moisture during winter. 

  • They are energy efficient and eco-friendly

Solar power is better for the environment, and it is a sustainable form of energy. As long as the sun is there, you will have energy. It will also reduce your electricity consumption because your air conditioner will not be working as much. This leaves you with a lower electric bill at the end of the month. 

  • They run silently

Traditional attic fans are very noisy and loud, unlike the silent running solar fans. All solar powered attic fans do not make any noise so you can have your cool home without a lot of racket from your fan. 

This means you can enjoy some peace and quiet throughout the day and have silent nights as well. You won’t even be able to tell whether the fan is running. 

  • They help save money

The only costs that you are likely to pay are for the upfront purchase and installation of the solar attic fan. Once this is concluded, the only running costs that you have to think about is the occasional maintenance.

You do not need to use electricity for this fan, and it will regulate your home temperature in a very cost effective way. Your air conditioner and heating system will have less work to do, and this means more money in your pocket at the end of the month.

Additionally, a solar attic fan preserves the lifespan of your roof so you are not likely to be forking out money for roof repairs or other issues regularly.

Buyers’ Guide – Solar Attic Fan

We at Cleaning King know how challenging it can be to know the technical aspects that you need to look for when searching for the best solar attic fan. That is why we have put together this buying guide to help you navigate your way around these products. 

Factors to consider when buying a solar attic fan

The perfect solar attic fan for you depends on the environmental conditions of your space, your needs, and your budget. Some factors that you need to consider when looking for the right solar attic fan for you include: 

  • The type of roof you have

Solar attic fans can be installed either on the gable or on the roof. If you have a flat or pitched roof, then a roof mounted attic fan would be best. If you have a gable, already go for the gable mounted fans.

  • How big your attic is

Attic size matters because it determines how efficient your solar attic fan will be at cooling and regulating the temperature in your space. Measure the size of your attic and ask about the minimum cubic feet of air per minute that the fan that you are interested in covers.

  • The roof and attic shape 

Generally speaking, steep roofs need a powerful solar attic fan to move the air around compared to a flat roof.  

  • Costs

Make sure you know the costs required not just for purchasing the fan but for installation as well. If you are going to engage the help of a professional, then you need to factor that cost in too. 

  • The position of the solar attic fan

Solar attic fans run on solar energy. Where to position the fan is critical to the efficiency of the fan. It needs maximum exposure to the sun so that it can run well. So make sure that wherever you place it, the fan will have access to the sun throughout the day. 

 

Features of a Solar Attic Fan

The Cleaning King team figured that you might not have an idea of what features you need to look for when purchasing a solar attic fan. The list below gives you a better understanding of the important features you should consider. 

  • Adjustable solar panels

Your solar panel should have an adjustable bracket. This will help you to manipulate it better for maximum sun exposure. 

  • Number of fan blades

The more fan blades the solar attic fan has, the more efficient it will be at circulating air. This also means that the unit will be quieter because each blade will not be working as hard. A minimum of five blades is what you should consider when buying. 

  • Durability

The solar attic fan panel is always exposed to the elements, so you will need to make sure that the product you are buying is of high quality and can withstand the heavy exposure to these extreme weather conditions.

  • Warranty

Check the manufacturer’s website to see the warranty that they provide. Usually the longer the warranty, the higher the quality of the unit. Because it is going to be exposed to harsh elements, a high-quality product with a long warranty is a good solar attic fan.

  • The motor  

A good quality motor will make sure that the fan is running smoothly and quietly. 

  • Check for Solar tax credits

Check whether the country or state you live in offers solar tax credits or some form of solar tax rebate that will save you some money on the purchasing and installation costs. 

  • Versatility and Easy installation

A solar attic fan that is designed for a wide range of roofs and spaces is a wonderful product to buy. In addition, look for a fan that will not need major changes to your roof, house structure and wiring. 

Conclusion – Best Solar Attic Fan

Whether you should buy a solar attic fan or not depends on your location and climate. If you receive a lot of sunlight, investing in a good quality solar attic fan is a worthwhile investment.
