Benefits of buying solar-powered attic fan

If the list above has got you curious, but you are still on the fence about whether or not buying a solar-powered attic fan is the correct choice for you, then we have got this covered. These attic fans with all their list of features might sound like they are simply too good to be true. It is understandable that you want to be fully convinced before shelling out hundreds of dollars on a product. Which is why we have below, a list of the benefits of buying a solar-powered attic fan.

Cost-Efficient

At first glance, you may have seen the price-tag and immediately wondered if going with solar power is really worth it. However, you have to account for the fact that these will require zero operational costs. This means that you can simply install them and enjoy the benefits. Most of these come with long-term warranties, so you won’t have to worry about any faults. Additionally, you can get a 30% federal tax credit for using solar-powered units.

Peaceful

As these solar-powered attic fans function as soon as the sunlight hits the panels, they are gentler than their electric counterparts. This means that they can promise a more noiseless operation, both in terms of the fan blades as well as the motor. This will allow these attic fans to keep your attic fresh without having to get used to the constant whirring noise.

Low-Maintenance

Most of these solar attic fans come with the required installation kit. While some may need you to drill some holes in your roof to fit them, there are other options, such as a gable-mounted attic fan. So installation as a whole, should not cause you much hassle or require you to hire a handyman. As there are minimal to no wirings, you will not have to worry about water damaging any circuits or any weather damage. They do not require any battery changes either, so all you have to do is clean the panels every now and then for a smooth performance.

High-Efficiency

When you hear that these solar attic fans promise a noiseless operation, it is easy to doubt that they can be high-functioning as well. However, once you look at the values, it is hard to deny how impressive they are. These solar fans can provide a very high airflow rate, some even averaging between 1700-2000 Cfm. These can effectively cover large areas of up to 2500 sq. ft. with just a single fan. So you are definitely getting a high value for your money. 

Features to Look for When Purchasing Solar-powered Attic Fan

So you have decided to go for a solar-powered attic fan? This is not only a great decision for the environment but also for your wallet. However, with so many options available in the market, it can be tempting to go for one that boasts of the most impressive line-up of features. It’s not always necessary that you actually need all these features. So to make it easier for you to pick out a solar-powered attic fan that is most suitable for you, here is a list of features that you should look out for: 

Space Coverage

Before you hit that ‘Add to Cart’ button, you need to do a proper assessment of the square footage of your attic. The typical way to go about this is that for an area under 2500 sq. ft., one attic fan should serve you just fine. However, if the area is bigger than this, then you will need more than one to see a noticeable difference. Another value to be on the lookout for is the CFM or Cubic Feet per Minute of airflow that the fan can provide. For an average estimate of your needs, you can calculate the square footage of your attic and multiply that by 0.7. This should help you get an accurate estimation of whether or not a solar attic fan will be able to efficiently cool your space.

Adjustability

When it comes to solar-powered devices, it is no surprise that adjustability is a very important feature. As most solar attic fans are designed for slanted roofs, it is difficult to ensure that your rooftop could provide the panels the ample coverage it was designed for. Therefore, it would be a bonus for a solar panel to offer a tilt feature. This would allow for maximum sun exposure, especially if you live somewhere where daylight hours are short.

Noise Generation

While most people would like to keep their attic fresh and moisture-free during the hot summer days, very few might be okay with the unpleasant whirring of the fan and the motor throughout the day. It is easy to get swayed by the high CFM values without checking if the attic fan can deliver a good cooling system without too much noise pollution.

Thermostat

Usually, most solar attic fans come with the option to get an additional thermostat with the solar attic fan. You may have glossed over this feature as it would add some cost however, it would make your overall usage much smoother. The accompanying thermostat would help to save energy by auto-switching the fan when the temperature or humidity reaches above-average levels. Some models come with a pre-installed thermostat as well.

Materials Used

When you invest in a product, it is only fair that you expect a long-lasting service. With this in mind, you should properly scan through the list of materials that have gone into the build of this attic fan. A cheaper build will not be able to withstand the constant UV exposure or offer the weather resistance that a solar attic fan needs. It needs to be able to withstand the changing weather as well as provide a certain degree of protection from rust. Many solar attic fans offer stainless steel or other strong coatings, which should be given preference over cheaper builds that erode easily.

FAQs on the Best Solar Powered Attic Fan of 2019

While brushed motors are primarily made from carbon, these brushless motors utilize magnets for power. This helps them function smoothly without excessive heating and minimal friction for all-around better performance.

Generally, attic fans should be installed on the top of the roof. The solar panels should be facing wherever they can get the maximum amount of sunlight. In terms of placement, they should be stationed at least two feet behind the ridgeline to ensure that they are not visible on the front face of the house.

As hot air gathers into your attic, there is likely to be high humidity and moisture gathered here. You can check your ceiling for dampness as well as the corners for mold. The other sign can be rusted metal bits such as screws or nails.

There are many solar attic fans that promise to provide the most noiseless operation. However, one of the factors you should look into can be the fan blades. When a fan has more fan blades, it means that each blade will have to put less strain and can promise a much smoother functioning. A wider width, too, can provide this benefit.

Wrapping up,

Solar attic fans are a great investment for keeping your attic properly ventilated and free from any rust or mold growth. Requiring no running costs and equipped with a sturdy build, these are likely to serve you for a long, long time. We hope this list above, as well as the buying guide, is able to help you make an informed decision and help you find a solar attic fan that perfectly suits your needs.
