With the Solar RoofBlaster Solar Attic Fan, you get the low-maintenance cooling for your attic that comes in an extremely durable as well as affordable package.
The major features of this solar attic fan are listed as follows:
Convenience
This solar attic fan comes with a mesh screen, which is essential in keeping any debris out. This will keep the fan functioning without any junk getting in its way. The installation is nearly effortless, and the fan blades will start spinning the second it receives any sun exposure.

Furthermore, it comes pre-installed on to a metal roof vent, so all you have to do is attach it on to your roof.

While other solar attic fans boast of high numbers in terms of square footage, attics are by and large, not the largest. This is where this relatively smaller attic fan comes in. Offering effective coverage for an area of 100 sq. ft. with a 39 Cfm, it is easy to doubt its performance when compared to other upscale models. However, with a 2700 rpm speed for the fan blades and a 3W solar panel, this is a rather efficient build that should work even if it isn’t the sunniest day out.
Durability
This galvanized metal build is sturdy and should be able to stand the test of time. The clips required during the attachment are also made of stainless steel. It comes with a 17-inch base to ensure a waterproof build. Not just this, but it has a rated operation life of 50,000 hours or 15 years with an estimated usage of 9 hours per day.

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.

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 2021
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.
