Are Solar Attic Fans Worth It: Pros and Cons

With solar energy taking over conventional power sources, no electrical device is left untouched, and so is the case with attic fans. Solar attic fans have become the talk of the town, and it is said that they can replace the existing cooling systems. Let us explore their pros and cons to determine are solar attic fans worth it.

Are Solar Attic Fans Worth it?

Yes, solar attic fans are worth it. These fans are a fantastic and eco-friendly solution for ventilating your attic. They operate without electricity thanks to their innovative built-in photovoltaic power system, harnessing the sun’s energy to power the fan. They assist your home in combating the scorching heat and relentless humidity.

Solar attic vent fans use solar energy to pull hot air from your attic and replace it with cooler air outside. Because of this, your HVAC system will need to work less to cool your upstairs living area. This can extend the life expectancy of your cooling unit and is a great option in contrast to replacing your air conditioning unit. These fans facilitate the constant circulation of both warm and cool air within a room, promoting optimal airflow.

Now, let’s go through the following pros and cons to understand if solar attic fans are worth it for you or not.

Pros of Solar Attic Fans

1. Eco Friendly

Solar attic fans utilize solar energy. Choosing a sustainable and renewable energy source over other forms of power impacts our future, and solar energy is good for the planet.

2. Silent

Noise is not an issue with these fans. These fans are very silent when compared to the noise produced by the powered fans.

3. Easy to Install

They are not only durable but also incredibly easy to install. You will be able to complete the installation in just a few hours without any hassle of wiring, assembly, or messy clean-up afterward. Unlike other appliances, solar attic fans are not affected by power outages during the day.

4. Safe

There is no risk of carbon monoxide with these fans. The powerful force of attic fans draws carbon monoxide from combustion devices into the attic due to the creation of negative pressure zones. Due to this reason, solar attic fans do not carry carbon monoxide risks. Apart from installing these fans, there are also other ways to reduce your carbon footprint as a student in school or college.

5. Damage-Preventing

During the winters, heat rises to the attic. To prevent roof damage caused by mold, wood rot, and ice expansion, a solar attic fan draws heat and moisture into the attic. It also prevents ice dams, helping to eliminate mold, reducing damaging moisture, and preserving the durability of roof structures and materials.

6. Efficient Heat Management

Managing heat is essential in summer because the temperatures can rise and reach more than 130° F (54° C). When faced with such situations, your solar attic fan can truly be relied upon. In fact, it has the remarkable ability to effectively decrease temperatures. A small temperature difference may not seem big, but on a hot summer day, you’ll be thankful for the cooler air. This is another determinant of whether solar attic fans are worth it.

7. Visually Appealing

The visual appeal of solar attic fans is even more captivating. Solar attic fans are more compact when compared to powered attic fans. These devices are mounted near the ceiling, minimizing distractions compared to other devices. Therefore, the installation of this device is a significant factor for numerous homeowners.

8. Different Mounting Options

There are three different mounting options available for solar attic fans: curb-mounted, gable-mounted, and roof-mounted. You can determine the ideal model based on the type of roof your property has- whether it is flat or pitched. Additionally, consider the specific pitch of the roof and the square footage of your attic.

Just learning about the pros won’t give you a clear idea about the worthiness of solar attic fans, you also need to consider their cons.

Cons of Solar Attic Fans

1. Higher Initial Cost

Solar attic fans come with a higher initial capital cost for homeowners compared to traditional models. While the savings on energy costs can gradually offset this investment over time, the upfront expense might be a significant barrier for some consumers.

In most markets, a single fan typically costs around $600, and installation expenses can range from about $150 to $300. Although a building permit is usually not required for this unit, certain jurisdictions may have specific regulations that entail additional costs. This should have also helped answer does a solar attic fan save money or not.

2. Long Payback Period

Recouping installation costs can be time-consuming. Opting for an Energy Star-rated solar attic fan may qualify you for tax credits of up to 30% of the initial expense. However, since you typically need two fans for desired results instead of a single traditional fan, expenses double. Cooling a 1,000-square-foot home with solar attic fans in a warm climate like Florida can save about $40 annually, necessitating about 10-15 years to break even with the investment.

3. Lower Power Output

To achieve desired results, multiple solar attic fans may be necessary. Due to their lower power output, these fans move less air than some other options. For homes larger than 1,600 square feet, three fans might be needed to maximize air movement and utility savings. Contractors often recommend this investment for those who regularly use the attic or occupy adjacent rooms. Alternatively, for cost savings, upgrading insulation, using a radiant barrier, or switching to a white roof might be more affordable options.

4. Sunlight Dependency

Solar attic fans require direct sunlight to function effectively. Without exposure to the sun’s rays, these fans won’t operate efficiently. Some communities may face challenges relying on solar power if they receive 150 or fewer sunny days per year. While using a large battery can mitigate this issue, it also adds to the installation cost. Before opting for solar attic fans, assess the amount of daily sunlight your solar panel will receive and consider factors like cloud cover and obstructions that may affect their performance.

5. Hindered by Drifting Clouds

The operation of solar attic fans heavily depends on direct sunlight. As most models lack a battery backup, drifting clouds can interrupt the fan’s function, causing it to stop immediately when light contact is lost. This can leave your attic with no improvement in conditions on hot days. Even premium models in this category typically move only around 800 cubic feet of air when fully operational.

6. Roof Structure Changes Required

Installing solar attic fans necessitates cutting holes in the roof. Some homeowners might overlook the need for multiple holes to accommodate the entire system. This may make it unsuitable for certain properties, as the installation’s weight could strain the existing supports at the top of the house.

7. Air Movement Limitations in Certain Solar Attic Fans

Opting for solar attic fans may result in reduced power compared to traditional models. While this has some advantages, it may not provide sufficient strength to effectively expel air from the attic. Combining this technology with passive airflow options can help control electricity costs and maintain stable temperatures above your living space. Some solar attic fans might only circulate hot and humid air instead of properly exhausting it, potentially limiting the expected benefits and improvements in attic ventilation.
