What Is a Solar Attic Fan?

Solar Attic Fan is a fan that improves air circulation by drawing in calm air from your roof space to exchange for cooler air from outside. By this, a solar attic fan aids in keeping your home well ventilated and cooler even without turning on the air conditioner. As the name suggests, these devices utilize solar energy to work and are more efficient when exposed to direct and intense sunlight.

Buying the best solar attic fan can be an overwhelming task. There is a wide range of options you can choose from, making it a bit difficult to know the type and brand that will serve your needs fully.

This article has picked five of the industry’s finest solar attic fans for you to review and decide on. However, before we delve further on these appliances, we have also lined up a solar attic fan buying guide that touches on the device’s advantages and factors that you should consider when looking for the best solar attic fan in 2020.

Why Should You Buy a Solar Attic Fan?

Remember that a solar attic fan is an all-season device you can use in summer and winter. Since the device exchanges warm air in your living space with cooler air from outside your home, you are more likely to reduce energy bills in the house, mainly because you won’t need your air conditioning system that much. Accordingly, a solar attic fan is more energy efficient since it utilizes solar energy, which is a gift of nature.

Solar attic vents will also help get you cozier by improving the comfort of your home. Since the device improves ventilation, it helps in air circulation within your living space. And what is more impressive is that solar attic fans do not pull hazardous gasses from other parts of your house, for instance, your basement, the same way an electric fan does.

Buying a solar loft fan is also the best way to safeguard your roof from damage caused by moisture build-up and the creation of mold on the surface. Excess heat is likely to harm the asphalt shingles during summer, while winter comes with moisture problems. However, when you have a solar attic fan, your ventilation is sorted, abating any possible damage and therefore saving you a lot of money in repairs and extending your roof’s lifecycle.

Most electric fans are similarly deafening and may disrupt your home’s peace and serenity. That is never an issue when you buy a solar attic fan. Solar attic ventilators are tremendously noiseless and will offer you the environment you require to unwind and relax after a long day at work. 

Advantages of Solar Attic Fans

• Eco-friendly – As we had said earlier, a solar attic fan utilizes unpolluted and renewable solar energy, making it environmentally friendly. This means that you have significantly reduced your home’s carbon footprint if you buy a solar attic fan.
• Cost-efficient – With a solar attic fan in your home, you will not need to run the air conditioning system all along, which helps reduce your electricity consumption. Accordingly, the device maintenance cost protects your roof, reducing maintenance costs.
• Easy to install – Solar attic fans do not require wire installation, making them more straightforward to install. You can do the work by yourself or opt for professional help, which should not come at an extra cost.
• Noise-free – Unlike traditional fans, solar attic fans are noise-free, meaning you don’t have to be overly concerned about the device keeping you distracted due to its noise in the background.

Disadvantages of a Solar Attic Fan

• Relies on solar energy – These devices rely on sunlight to perform efficiently. It means that the performance is greatly affected if the conditions do not guarantee enough sunlight.
• Less powerful – Solar attic fans are not as powerful as conventional fans, meaning they may not offer the same degree of service as a motor-based or electric fan would.
• Costly – Solar attic fans are relatively more expensive upfront. However, they are more cost-effective in the long run.

Factors to Consider When Buying a Solar Attic Fan

Buying a solar attic fan may not be a walk in the park because they are available in a wide range of models, sizes, and types. Therefore, there are many issues you should keep in mind when you decide to buy one. Considering that you want to pick a solar attic fan that works best for your needs, you have to look into various factors.

We all have choices and preferences in everything. What you want is, therefore, entirely up to you to decide. Here are some factors that can guide you when buying the best solar attic fan for your home.

Material

Like any other thing that you would like to use for ages without replacement or frequent repairs, a solar attic fan should be durable enough. And the first thing that comes into the equation is the material used to craft it. The material helps you determine how durable the solar attic fan is. A solar attic fan made from the most durable and high-quality material, like aluminum, lasts longer since it is robust and tolerant of various environmental hazards. 

Stainless steel is also excellent for durability and better performance, as you will not have to worry about corrosion or rust. On the other hand, plastic materials may not be a good option since it breaks easily, piling up costs, which you should avoid as much as possible.

Additionally, you may want to check on the solar attic fan’s construction because it plays a significant role in the device’s performance.

Size

The size of a solar attic fan depends on various factors in your home. For instance, you will need to identify the size of your living space. Solar attic fans work better to recirculate air when used in a proportionate space. The best way to go about this is by measuring the length and breadth of your attic and multiplying it by ten.

Ease of Installation

It is crucial that you go for a solar attic fan that is easy to install in your home. This factor depends on other issues like the size of your living space, the material used to craft the solar attic fan, and the model. An easy-to-mount solar attic fan has all hardware you require to get it fixed in your home. This helps you to troubleshoot or detect problems when any arise and saves you time and energy.

Below is a video on how to install a solar attic fan:

Efficiency

Solar attic fans are more efficient than conventional fans because they run on solar energy. However, you may want to counter-check if this guarantees better performance without any hassle. Combining efficiency and cost-effectiveness should help you save a lot of money in the long run.

Performance

Solar attic fans with more powerful motors offer the best performance you can ask for. Your device should guarantee long-lasting solutions in terms of performance and noise reduction. Consider going for models that have more blades because they are less noisy. If you want to turn your room into a safe and serene haven for relaxation and unwinding after a long day at work, then you should consider solar attic fans that are not noisy.

Adjustability

You should buy a solar attic fan that can always assist you. A more significant factor that you should consider here is whether it is adjustable.

And talking about adjustability, we refer to the solar panel because it is the most massive part of your solar attic ventilator and by far the most vital since it is used to tap the solar power required to run the fan. Positioning the panel according to the sun’s position is much easier if it is adjustable, meaning that adjustability is an essential feature that should be ignored.

The Fan

Another vital part of the solar attic fan is the fan. This is a dynamic unit of the attic fan; therefore, you should be keen on how it is designed.

You need a fan that is easy to clean and makes the least noise. With that in mind, it is recommended that you go for a multiple-blade fan. More blades mean less noise and extensive unit coverage.

The Motor

This is the most crucial part you should consider other than the power source. As mentioned above, an inaudible motor is more efficient, depending on your attic’s dimension. You may consider buying many low-power solar attic fans or a single high-power one if you have a larger living space. However, a large solar attic fan will likely be noisier since the motor will be large enough to reflect its size.

For better performance, you may want to buy many lesser solar attic fans.

Safety Concerns

Safety should always be a priority consideration in everything you buy for your home. On top of that, you must be sure of the safety of the things you buy. Safety in solar attic fans is mostly assured if you buy a protected one. Protective units are essential in ensuring the fan is protected from corrosion and other factors that may damage it and lower its performance. Accordingly, such features help to ensure no bacteria get in with the air from outside.

All factors point to the device’s efficiency and safety; therefore, it is crucial to keep them in mind as you buy a solar attic fan for your home.
