Benefits of a Solar Powered Fan

When it comes to solar attic fans, the major benefit is that you no longer need to depend on electricity for its operation. It is sure to cut down your overall energy consumption.

There are two types of solar vents available in the market. Each with their individual characteristics and conveniences. Now, let us take a look at how they benefit you.

Roof Mount Solar Attic Fan

The roof mount solar attic fans are supposed to be installed on pitched or flat roofs. These fans can also be placed in lofts, detached garages, barns, and workshops. Its roof hugging design can handle tornadoes and hurricanes without any panel adjustments. Even in scenarios where the panel gets damaged because of natural calamity, it can easily be replaced separately. You won’t feel the need to replace the whole unit.

Gable Mount Solar Attic Fan

The gable mount solar attic fans are mounted behind an already existing gable vent. Its solar panel can easily be set up to an exterior wall. These gable fans are larger in size compared to the roof mount attic fans. If the gable is absent, then the installation process of a gable mount attic fan is more technical.  

Looking at the bigger picture, solar power is an ultimate renewable energy source. The sunlight is sustainable energy that is fully renewable and has a low carbon footprint. Solar-powered attic fans have simple installation and are eco-friendly. These fans offer more mobility and are very low maintenance. They require no external electrical connections, so you won’t have to worry about additional electric wires and extension cords.

Furthermore, the solar-powered attic fans are pollution-free and will never cause any mishaps or accidents like a short circuit, outburst of flames, or shocks.

Things to Consider Before Buying a Solar-powered Attic Fan

The most important thing to keep in mind the size of your home attic. Here is a list of things to help you go through this whole process.

Attic Size

You can obtain this by multiplying the width and the length of the attic floor.

Fan location

You can either opt for a gable installation or a roof installation. It can just be in the middle of the main part of your attic.

Ridge Vents

These vents usually remove hot air from the attic. So, there is no point in installing a solar-powered attic fan, as it will end up drawing in air from the ridge.

Fan Thermostat

You can set the thermostat in order to cut in-between 100°-110°. Although, in situations when the moisture level rises in the attic even humidity sensors are helpful in cutting the fan on.

Cord Length

When you are choosing a solar-powered fan, the most important thing you need to determine is where the solar panel should be placed for it to get the most sun. Then you determine where the fan will go and measure the distance between that area and select a solar-powered fan that offers a cord that is long enough for you. Ideally, you can keep them relatively close together because an overlong cord could pose a tripping hazard.

Choosing the Perfect Solar Powered Fan

Any additional feature available with the product you buy can be an added advantage.

When you are comparing solar fans, you should focus on the space they are supposed to cool. The noise output, size of the fan, and its solar panel are the most important criteria to keep in mind before settling on a product.

Size of the Fan and Solar Panel

If you settle for a fan that is too large for your room, then it may dwarf the room. A poorly placed solar panel can ruin your decor and be an eyesore. The size of your solar panel can directly affect the fan’s performance. If the panel is large, then you may have trouble positioning it in full sun. In this case, you might not be able to gain optimum usage from the fan as it won’t last for a long time. The best solar-powered fans are available with compact solar panels. They also have a long cord, which gives you more freedom to position the fan.

Noise Output

All fans are known to produce some noise. It usually is not enough to bother you, but some really loud fans can make fun activities like listening to music, having a conversation, or watching TV more challenging. You should focus on fans that can deliver powerful, cooling air circulation without being loud.

Amount of Space the Fan Covers

When you are choosing a solar-powered fan for your home, it is important to consider the size of your space the fan needs and fits in in order to have an idea of the appropriate model. If you have a small space, you can get a tabletop or lightweight, portable solar fan. But larger areas require a freestanding or ceiling fan that can ensure adequate coverage.

FAQs on Best Solar Powered Fan

Solar power systems work by using stored energy that is collected from sunlight. The solar panels included are constructed with a series of photovoltaic cells. These cells can grab the sunlight and turn it into usable energy.

A solar attic fan can prevent your roof shingles and extends its overall life. During colder days, an attic fan helps to remove moist warm air produced after regular use of heaters.  This hot moist air makes a favorable circumstance to help mildew to grow on the interiors of your attic. It can also rot the underside of the roof sheathing.

A wide range of fans can be solar-powered. You can find a solar-powered box fan or a solar-powered room fan. Some of these fans can go in the attic, tents, or the RV. It can also be carried around as a personal fan anywhere outdoors.

These solar power options also offer several styles like clip fans, stand-alone fans, and even portable solar-powered ceiling fans.

You can find various portable personal fans that come with multiple functions like flashlight and table lantern functions.

Conclusion

Buying solar-powered attic fans can be complicated. We have sorted out a list of solar attic fans available for you to choose from. Available with different sizes ranging from short to long, with different capacities and functionalities. Although many solar-powered attic fans have similar features, deciding which one is best for you depends on your specific requirements.

After going over the solar attic fans compiled above, you can easily pick the one you like the most.
