Benefits of a Solar Powered Attic Fan

Benefits of a Solar Powered Attic Fan

Roofs are made in such a way that they absorb the heat from the sun. So what happens is that since the attic is located between the roof and the ceiling, the absorbed heat radiates to the attic location. What you don’t know is that the temperatures of the attic can rise up to 150 degrees with high levels of solar heat with poor ventilation. This leads to higher electricity bills.

When the attic overheats, it can have catastrophic effects on your home. The excess heat will lead to more work being exerted on the air conditioner for it to be able to balance the air in circulation. Besides, the extreme heat in the attic could combine with moisture leading to wood rot, mildew, rust, and mold on the roofs and other parts of the house. In addition, the rooms that are adjacent to the attic will experience extreme heat, especially during the summer, even with an air conditioner at hand.

To avoid all that, you can opt to install a solar-powered attic fan in your home. This, too, works wonders when it comes to enabling effective ventilation in the attic space. It does so while saving you on the electricity bills. It works by creating a balance between the extra hot and cooler air. The fans in the solar attic are made in such a way that they can force the extra heat out.

Solar-powered attic fans offer an effective and convenient option to cool an attic on any property.

How Do Solar Powered Attic Fans Work

To learn how a solar-powered attic fan works, you first need to understand the importance of ventilation and the role of an attic in all that. During cooler seasons, the attic provides an escape from the extra moisture in the house. In hot seasons like summer, the ventilation helps bring a cooling effect by allowing the hot air to get out via the attic. If you live in an area that experience different seasons all year round, proper ventilation is key for a healthy, comfortable and safer home.

Ventilation helps to bring an air balance in your home. Besides, it ensures that the structures in your home, especially those around the ventilation room like the roof, have a longer lifespan. Poor ventilation leads to moisture accumulation, rotting of the roof, rusting, and roof failure. Accumulation of molds and mildews in the attic could also tremendously decreases the air quality all the way to the living room.

A solar-powered attic fan works by allowing an exchange of air between the hot air in the attic and the cooler air from outside. While the hot air gets out, the venting present in the attic receives cooler air creating a balance. Because of that air exchange, the solar attic helps lower the heat in the space to up to 50 degrees. It also helps reduce the moisture content present in the attic. This lessens the effort put in by your HVAC system in ventilating the upstairs.


Benefits of a Solar Powered Attic Fan

Compared to the traditional attic fans, solar-powered attic fans have been proven to have a slew of benefits. Read through to see the advantages it will have in your home.

Heat Removal

It helps rid of the excess heat in the attic and consequently in the whole home. Extra heat in the attic leads to overworking your HVAC system. This, in turn, leads to more bills. By removing the excess heat, it ensures proper ventilation, which makes the home comfortable. Having one properly installed can have you experiencing a temperature drop to up to 40 degrees which is a huge win, especially during summer. Enabling a drop in the attic temperature gives room for the heat in the rest of the house. This principle is what makes the home comfortable.

Reduced Heat Damage

The temperature in the attic can go as high as 160 degrees Fahrenheit on a single day. The heat can end up in other parts of the house, leading to heightened temperatures. Other things that can lead to a buildup in temperature in the attic include laundry, showering, and cooking. During the winter season, water gallons reaching the attic could go all the way to 28 gallons which may result in wood rot, mildew, and molds.

The solar-powered attic fans are made in such a way that they force extra heat and moisture out of the attic. The outcome is that your roof says intact, which makes it last longer. Without the heat and moisture control, the areas near the attic could be brittle and susceptible to cracking and collapse.


Solar Tax Credit Benefits

Another advantage is that it helps keep your home safe from dust and other disastrous allergens that could otherwise be harmful to your health. As the heat and moisture are forced out of the attic, it carries with it harmful allergens.

Also, those seeking to install the solar attic fan can access the federal tax credit to up to 26 percent.


Eco-Friendly

Solar-powered fans can lead you to the energy independence that you’ve been longing for. By relying on the sun to power your attic, it will help you cut your electricity costs. As a green component, it helps lower your carbon footprint, which tremendously adds to the longevity of your roof and the structure.

Since a huge percentage of electricity relies on carbon fuels, while a chunk of roofing products come from petroleum ingredients, this will be a good way for property owners to move towards a green economy as they strive to head towards zero-carbon.

Money Saver

Installing a solar-powered attic fan will also save you some money. Who doesn’t want that extra coin with the uncertain times that we are living in? First, your attic fan will not be running on electricity anymore. Since the ventilation is required 24/7, an electricity-based attic will be on through, which may raise the cost of the same when the bills come. By going green, you rely on solar energy, which is free all year long.

Moreover, a solar attic properly rids excess heat and moisture, which h means that your roof and other assets close to the attic are safe from damage like rotting and developing molds. This would otherwise lead to maintenance costs and even replacing of the roof after a short while, which is quite expensive.

No Noise

Most fans can get to you with their continuous noise throughout the day. For those that would love to enjoy the comfort of their homes without any noise, then the solar attic got you covered. Better still, you enjoy a comfortable night's sleep as they don’t run at night.

Besides, when your HVAC system overworks, it means that the maintenance also goes up. That’s not the case with a solar attic. The 26 percent federal tax credit excluded, you can even reduce the heat load in your attic so low, that even your AC unit will shut off at night!

And that no only saves you money, from it not running, but you can sleep better without its constant drone!

Easy to Install

Installation only takes a few hours with most fans. There is no serious wiring that goes into installing the solar attic fan. They come when complete and ready to be installed.

The best Solar Star attic fans are so ruggedly dependable, cleanly designed and efficiently functional that skilled installers can complete the whole process in under an hour!

Withstand All Weather

Also, they are designed to withstand whatever weather, from windy to extreme rains, with hailstones. They cannot be brought down by any environmental hazards. Those from locations that experience hurricanes can feel safe with them too.

In fact, solar powered attic fans are so wonderfully functional that the premium fans not only work but are designed to thrive and provide missive benefits to you regardless of the weather extremes!

The brutal summer temperatures in Texas and other southern states slam your attic's weather barrier with massive doses of solar radiation that rapidly heats your attic to lethal levels of heat! That heat needs to go somewhere and your cool interior rooms are the victim as the heat works its way through your insulation. Your solar powered attic fan gracefully and silently pulls those brutal temperatures out and allows cooler air in through your soffit vents.

The other extreme is cold in the wintery norther climates. The two deadly issue you suffer in the winter are condensation inside your attic and ice damning on the outside! During the winter, even in places where is it normally warm, temperatures can fall fast. Damp air trapped inside your attic, from shower, kitchen or laundry vents dumps moisture into your attic, and then the cold air on your roof causes condensation. the condensed moisture from the air drips into your insulation and can cause packing, water damage and worst of all mold blooms. The other potential issue is ice damning, where warmer air trapped inside your attic melts the ice against your roof while the surface remains frozen in the cold. That temperature difference melts the ice and it flows up under your shingles to attack your roof causing leaks and water damage!

Solar Powered Attic Fan Installation and Warranty

Installation for most fans takes a short time, approximately two hours. This is because no wiring goes into the process. The equipment comes ready to be installed, and with skilled personnel, it will be up and working quickly.

The attic fan can be mounted on any type of roof, whether metal roof or tied. It also fits well on any roof design, so you don’t have to fret over that. Once the installation is over, you don’t have to worry about leakages or leaking. The fan is seamlessly fitted into its position. And because no wiring or assembly of any kind goes into it, the whole place remains as it initially was.

8 The Best Solar Powered Attic Fans

After looking at the benefits of the solar attic fans, you dint have to rush and install one. There are varieties in the market, and reviewing their properties will help you land one that's suited for your home needs and design.

The Best We've Installed...

We have handled all the others, in almost decade of installing solar powered attic fans.

The Solar Star attic fan series from Solatube International, while little known, is hands down the best fan we have installed.

The Solar Star solar powered attic fan comes in two manageable main pieces, plus all the other required parts. The lower flashing & fan's main body make up the fan. Both are easy to use and position on the roof. The seamless powder coated flashing is of exceptional in every way, just holding the flashing you can feel the substantially greater thickness and strength. The fan itself is a smooth ergonomic, single seamless frame designed to be leak proof with multiple redundant safeties. The bottom and blades are thick nautical grade polymer which is vastly more weather and pest resistant. The blades and underbelly will never corrode or suffer the thermal warping that is so common with the bound and unmoving 'whirly-birds'. The direct drive on the panel means you get maximum efficiency, silence and power from the best panels money can buy.

These awesome fans are currently available in three versions. They come in 35 & 16 watt roof mounted versions, and a 16 watt interior mount version. The roof mounted versions are installed directly into your roof and expand your attic's ventilation. The interior mount version installs inside your home and adds a solar powered fan boost from the inside of your existing ventilation structures, like 'whirly-birds' and gable openings.

Best of all, the Solar Star fan is wholly manufactured in the United States.

The Second Place Finishers...

All the other fans that we have installed do get the job done. They all work and have strengths & weaknesses like everything else.

They will however not be our favorites for one or more of four common factors, call them 'fatal flaws':

Flashing Quality: Flashing is literally the base of every attic fan. It may be a silly prejudice, but we like thick beefy flashings that can withstand Texas hurricanes. The Solar Star flashing is great, and the others just don't feel to the touch like they can measure up.

Single Unit: This is more an installation & ergonomics issue than a design issue for customers. When the solar powered attic fan arrives with the flashing as part of the unit, it becomes extremely difficult to install the weight, especially on steep roofs. The single unit and flashing combination makes maneuvering the device into place difficult and dangerous. Hold a 35lb fan & flashing combination, with one hand, while dangling from a safety line, leaning over on a 12:12 pitch roof (45* angle), while using one hand to hold the mounting screw, and your other hand to hold the drill... yes, you need three hands to get it done... it becomes a two installer job to do it safely on those steep roofs.

Seams: Seams seem (hahaha) to be a small thing until you remember that weather barrier failures, read that euphemism as LEAKS happen at seams. The more seams your product suffers, the more failure points are designed into the system. We avoid seams at all costs and will not warranty materials with seams.

Too Many Moving Parts: This is related & similar to the 'Seams' issue. When a component on your roof has all kinds of angles, bolts, screws, panels and moving jobbies it complicates the device. Complicated devices have and create by design potential points of failure. Every unsupported screw penetration into a housing means that moisture can follow the screw into the device. Every moveable exterior panel not screwed down can be victim of violent weather. More parts and more steps can create more installation issues that may inadvertently cause performance issues down the line. A tiny little moveable solar panel will just not produce the same amount of power as an imbedded and impact resistant larger panel.

These issues are knit-picky and annoying, but can effect the quality of ventilation delivered, installation issues, and likelihood of eventual leaks.

2. SOLARO

SOLARO is among the favorites when shopping for an attic fan. It’s made of quality materials which enhances its efficiency. It comes in different designs. You can opt for the gable-mounted, which is more of the normal type and portable, or the roof-mounted with fixed permanent solar. The fans have a 25-year warranty making it safe for customers.

2. YELLOWBLUE

The YELLOW BLUE solar attics are made by aerodynamic engineering with quality materials to withstand any weather conditions. They come in varieties from the portable model, roof-mounted and gable-mounted. Besides, they have one made specifically for snowy regions made of tiles. The warranty on these fans is limitless and is placed at a 360-degree angle in relation to the sun.

2. REMINGTON

If you are looking for the most popular attic fan in the market, the Remington should be your purchase. They have a thermostat as well as a humidistat that ensures proper ventilation. They are designed in such a way that they add or lower the velocity of the fan depending on the existing temperatures.

Moreover, they come with an adapter that aids in shifting from solar to electric power with ease. The good thing is that it will get back to operating on sun energy automatically once it detects the UV rays because of the sensor.

2. BROAN

What makes this solar attic fan fall in the category of the best in its price. If you are low on budget but still want the experience of a carbon-free solar, then BROAN will sort you out. The only downer is that it doesn’t work as perfectly as the SOLARO, and the likes as its CFM is slightly low. Moreover, it has neither a humidistat nor a thermostat. It can, however, serve those with limited space.

2. US SUNLIGHT

This one is mounted on the roof in a tiled position to properly tap into the UV rays. It stands out because its ventilation can cover a wide area. However, it’s important to note that this type of solar fan can only be mounted on a shingled roof. So, if you have a metal roof, tiled, flat, or slate roof, this will not be your pick. Moreover, it’s not equipped with electric functions like the REMINGTON and other competitive solar fans.

2. NATURAL LIGHT

It’s a roof-mounted solar fan with mundane properties. The solar panel on this one is tilted, providing a large surface area for trapping sunlight. It’s also very quiet, making a home comfortable to thrive in. The only downside is that it can only be installed on shingle roofs and that it can’t switch to electricity-powered mode.

2. AIR VENT

Air vents have a variety of solar fans to choose from. They range from gable-mounted to roof-mounted. Besides, if you opt for the roof-mounted, you can decide to either pick one where the fan is separate from the panel or vice versa. The watts that are available range from 10-25 watts. Besides, they run on a warranty of up to 20 years, making them safe in case of a breakdown. Unfortunately, they can only blend with shingle roofs and do not have an electricity adapter.


If You Have Any Questions...

If the ventilation of your attic and, subsequently, the comfort of your home is key, then installing the solar-powered attic fan should entice you. They help create a balance in the air within your attic by forcing the extra hot air out while allowing cooler air in via the vent. While at it, they ensure that you are saving on utility bills while contributing towards a carbon-zero environment. The installation process only takes a few hours, and no wiring goes into it. Before getting one, review the types available and find one that goes well with your roof type and design.
