Overview: What Is A Solar Attic Fan

A solar attic fan is a type of ventilation fan that uses solar energy to draw hot air out of an attic, thus, reducing temperatures and humidity levels inside the home.

The fan is powered by a solar panel, which uses sunlight to generate electricity and run the fan’s motor.

Solar attic fans are a cost-effective and environmentally friendly way to cool your home, reduce energy consumption, and protect your home from mold and mildew.

Interestingly, solar attic fans come in different sizes and styles, but all work on the same principle, that is, using the sun’s energy to power a fan that exhausts the hot air.

Both the appearance and functionality of solar attic fans often vary based on the manufacturer or model.

As such, they come in various sizes, shapes, and colors.

Furthermore, they are made of different materials. Some are built with monocrystalline contents, while others have polycrystalline contents.

That said, you should also know that these units can either be roof-mounted, curb-mounted, or gable mounted.

However, you should consult with a dealer to know which one is best for your home.

How It Works: What Is A Solar Attic Fan

I suppose by now you’re wondering how a solar attic fan works. That’s what am about to do for you.

I’ll explain to you how a solar attic fan works, and how you can make the most of it.

A solar attic fan works by using solar energy to power an electric motor, which then spins a fan blade.

Usually, the primary function of the fan blade is to draw hot air out of the attic and exhaust it to the outside.

This helps to reduce the temperature in the attic, which keeps the house cooler and more energy efficient.

In most cases, you’re required to mount the solar attic fan on the roof of your house.

Like every other solar technology, it is powered by a solar panel.

The solar panel collects energy from the sun and converts it into electricity, which is then used to power the fan.

Almost all solar-powered fans operate on the principle of a tiny photovoltaic solar panel, which supplies electricity to a small motor.

Solar attic fans function very well, even with the use of a power grid. There’s no need for it anyway.

They also do not require complex wiring, making them easy to install.

Most solar attic fans come with a pre-rated thermostat that often dictates when it goes on and off.

This helps to save both money and energy.

Pros And Cons: What Is A Solar Attic Fan

Here, you’ll find some of the pros and cons of a solar attic fan. However, I’ll begin with the pros before moving on to the cons.

Pros

No After-Installation Cost

One good thing I like about a solar attic fan is that you won’t have to spend too much on its operation after the initial installation cost.

In other words, there are no extra operating costs after the installation, except, of course, in situations where damage is incurred.

Also, if you are scared of high energy bills, let me put it forward to you that a solar attic fan will not add an extra cost to your energy bill. That is, it is energy efficient.

Doesn’t Steal Cool Air From Your Home?

Some people are still hesitant to invest in a solar attic fan because they fear that it may steal cool air from the rest of their house.

Away with that. Don’t be like some people. A solar attic fan will not steal air from the rest of your house. In fact, it helps to ensure that your home is kept cool at all times.

So, don’t waste your time contemplating whether or not to invest in this. Hurry up and get one for your home now.

Less Noise

Another thing worthy of note about solar attic fans is the noise level. For the most part, solar attic fans are relatively quiet.

They are not as loud and noisy as the powered attic fans. This alone gives them an edge over their counterpart (powered attic fans).

No Electrician is needed.

Thankfully, there’s no need for you to hire an electrician to install a solar attic fan in your home since it derives all of its energy from the sun.

This is actually good news for you. Not only will it save you money, but it will also save you from electricians who overcharge for the services they offer.

No Danger From Carbon Monoxide

Normally, powered attic fans are designed in such a way that carbon monoxide from combustion appliances can be pulled into the attic.

However, it’s not really the same with solar attic fans. With a solar attic fan, there’s little or no danger from carbon monoxide.

Visually More Appealing

Solar attic fans tend to look more aesthetically pleasing than powered attic fans. This is due to their magnificent design.

They have a lower profile than powered attic fans and are closer to the roof than their alternatives. This makes them popular among home users.

Save Your Roof

Usually, during winter periods, heat rises to the attic. A solar attic fan helps to pull the moisture in and heat out of the attic to prevent roof damage from mold, wood rot, and ice expansion.

A solar attic fan also helps to protect your roof against ice damming. All these, among numerous others, are the pros of solar attic fans.

Cons

Very Expensive

One of the major drawbacks of solar attic fans is their cost. They are usually very expensive and cost a great deal for their installation.

A single solar-powered attic fan can cost around $600-$700, with an added installation cost of about $300. That’s a huge sum.

In some cases, your home may require more than one solar attic fan. That means you may be spending twice the price.

Less Efficient if Overcast

Sadly, solar energy isn’t always effective, especially when the sun goes down. This, no doubt, is one of the major drawbacks of solar technology.

If you live in an area with often overcast or cloudy weather, a solar attic fan may not be the best option to meet your cooling needs.

Therefore, you may be forced to explore other options or alternatives.

May Cause Roof Leaks

If the solar attic fan is not installed in the right and appropriate way, your roof may end up paying for it.

So, ensure that the installation is done by a professional attic fan installation company. This will help to minimize cases of roof leakage.

Low Monetary Savings

With a solar attic fan, you can save both energy and money you would have otherwise channeled to other resources to meet your cooling needs.

For instance, with solar attic fans in a 1000-square-foot air-conditioned house, you can save up to 460 kWh worth of energy in a year. Convert it to money, that’s about $40 in a year.

Important Factors To Note When Buying Buying A Solar Attic Fan: What Is A Solar Attic Fan

Before buying any solar attic fan, it’s important that you consider these factors.

Efficiency

Solar attic fans are highly rated for their efficiency. You don’t need to connect them to electricity. They are powered by energy from the sun.

Due to their efficiency, you may qualify for Federal Solar Tax Credits by purchasing one of these units for your home.

Now that’s amazing. And I can assure you that solar technology is the way to go. Not only will you save money and energy by using this solar technology, but you’ll also contribute to the ecosystem.

Material Quality

The material makeup of a unit often determines how durable it will be in the long run. However, for a unit like this, you cannot expect anything less than high-quality material makeup.

Just like I said earlier, this unit is made up of both polycrystalline and monocrystalline contents. Below are some other materials used in the manufacture of solar attic fans.

  • Seamless, commercial-grade, pure-grade aluminum powder-coated flashing.
  • Stainless steel protective animal screen
  • High-impact, adjustable solar panel
  • Direct current, long-lasting quiet motor
  • 5-wind precision balanced fan blade made of non-corrosive aluminum

Warranty

Another factor you should consider before buying a solar attic fan is the manufacturer’s warranty or dealer’s warranty.

Once your solar attic fan has been installed in your home, follow up with your contractor to ensure that the new unit is registered for warranty.

The warranty, as you know, helps to provide parts and labor coverage for the unit in case there’s any minor damage or even malfunction.

So, it’s really important that you buy from a trusted manufacturer or dealer with a good buyer’s review. This will indeed help to put your mind at ease.

Adjustable Solar Panel

Another thing you should look out for when buying a solar attic fan is the adjustable panel.

Because the solar attic fan operates best when receiving direct sunlight, it is, therefore, important that you go for one with an adjustable panel for maximum collection of sunlight.

There are different kinds and models of solar attic fans with adjustable panels for you to choose from. You can also check out the ones I’ve listed in my recommendation table.

Ease of Installation

Generally, solar attic fans are very easy to install. They don’t require any complex wiring before you can start using them.

However, when installing a solar attic fan in your home, it’s best you hire a professional solar attic installation company to carry out the job for you.

This will actually help in preventing any complications that may likely occur during the installation process.

Also, by hiring a professional solar attic fan installation company, you may even be lucky to enjoy the maximum discounts and other benefits they offer.

Noise Level

There’s nothing as painful and annoying as being disturbed by the noise that comes from your home appliances or equipment.

Although, there are people who don’t find those noises really disturbing.

However, there are some who can’t stand even a whisper, especially if they want to take a nap or study.

Thankfully, with a solar attic fan, you won’t have to worry about noise as it has a very quiet operation, with a noise level usually below the sound of a normal conversation.

That’s quite impressive. So, don’t hesitate to make the right choice today. Invest in one of these units, and in time to come, you’ll be glad that you did.
