Why You Need a Solar Attic Fan 

If you have an attic or a bedroom upstairs that gets very hot during the summer, it is best to consider getting a solar-powered fan. Solar fans operate using the power of the sun. It pulls heated air out of your attic or bedroom and replaces it with cooler air coming from the outside

This helps reduce and lessen the load and work your HVAC system has to do in order to cool down your upstairs living area. 

It is worth noting that attic fans do more than just regulating the temperature in your attic. They work to take moisture and humidity out of your upstairs rooms or attic. This is vital because this helps prevent harmful elements such as mildew and mold from forming. 

Homes today need these solar attic fans to prolong the lives of roofs, save on electric bills, and preserve and maintain the attic’s structural strength and durability and your home as a whole. 

Types of Solar Attic Fans 

There are plenty of advantages to getting a solar attic fan. These fans are a kind of ventilation unit that adjusts and regulates the attic’s temperature levels. Basically, they pull out hot indoor air and expel it outdoors. 

There are two different kinds of attic fans. The roof-mounted attic fan and the gable mounted attic fan. Here are the differences: 

Gable Mounted Attic Fans: A gable attic fan helps to ventilate your attic efficiently. They lower the risk of wear and tear on your attic’s materials while decreasing the area’s temperature. It also helps bring down your electric bill. 

Roof-Mounted Attic Fans: The roof-mounted attic fan requires a vent hole at the top of your roof. This fan sits on top of a plastic or metal base over its vent hole. Once the fan is mounted, you will place shingle sheets around and over its base flashing. Just like the gable-mounted attic fan, roof-mounted attic fans decrease your electric bill significantly. 

Choosing Between Gable-mounted Attic Fans and Roof-mounted Attic Fans

Here are some things to consider before choosing between the two types of attic fans: 

Energy Efficiency: Most roof-mounted attic fans are not solar-powered. These fans get their electricity from its mounted solar panels. However, some gable-mounted models use solar power, but despite that, they need more exposure to sunlight and are known not to be as efficient. 

Cooling Capacity: If we are talking about larger areas, gable-mounted fans have a more significant advantage over roof-mounted attic fans because they are made considerably bigger than the latter. 

Maintenance and Installation: Roof-mounted attic fans are much easier and simpler to install compared to gable-mounted fans unless your home already has a gable vent available. 

How to Take Care of Solar Attic Fans 

Maintaining and taking care of your attic fan is an on-going process. It is essential for getting the most out of your investment. Despite being made of sturdy and high quality materials, it is still best to take good care of your solar panels and fans. 

In turn, you will get to enjoy its benefits for a more extended period. Here are some tips on how to care for your solar attic fan: 

1. Keep debris off the roof and around the fan

In time, gubbins and debris like leaves and branches will collect on your roof. It is vital to keep your roof clear of this debris to maintain your roof’s durability and integrity at the same time, protecting your solar fan. 

When debris gets caught in the blades of your fan, it can cause potentially severe mechanical failure. Tree branches can also cause some cracks and scratches on your solar panel unit. Make it a habit to clear off debris at least once every few months. 

2. Occassionaly check your solar panels for obvious damage

Since you are already on the roof clearing debris, check your solar panels for some apparent damages, damages like cracks, scratches, and chips. These types of defects will weaken the stability and toughness of the solar panel while lowering its efficiency. 

In case you find any damage, you can always contact the contractor who installed your solar attic fan for possible repairs or part replacement. 

3. Always use a damp towel  to clean your solar panels

Solar fans run entirely on power generated by its unit’s solar panel. To maintain optimum power efficiency, you have to clean its panel regularly. In time, layers of dust and pollen will build upon the solar panel’s surface. Cleaning solar panels are relatively easy and simple to do. Just use a damp towel to wipe off any dust on its surface, and you are good to go. 

Your location depends on how often you have to clean your solar panels. If you live near a desert area with plenty of dust, you need to clean more often than someone who lives in a cooler or wetter climate where it rains more frequently. 

4. Keep a clear line of sight from your solar panel to the sun

For maximum efficiency and effectiveness, ensure that your solar attic fan has a clear line of sight to the sun all day long. If needed, trim tree branches that may be covering or shading your solar panels. 

5. Check your unit for rodent damages periodically 

Your attics and garages often attract rodents like mice. One mouse can cause significant damage to the unit. It is best to check your units often for chewed fan blades and wires. Chewed wires can cause the unit to shut down completely, and it can also pose a fire hazard. At the same time, damaged blades can affect your fan’s airflow. 

Things to Consider When Buying a Solar Attic Fan (Buying Guide) 

There are some key things to consider before purchasing a solar attic fan. The appearance and functionality of a solar attic fan can vary depending on the model and manufacturer. These fans come in different sizes, shapes, and even colors. 

Solar attic fans can either be roof-mounted or gable-mounted. The right attic fan depends on whether your home has a pitched or flat roof. It also depends on the size or square footage of your attic. 

To give proper and sufficient ventilation, your fan must have the appropriate venting capabilities. The size of the solar panel can determine the venting capacity. Usually, for residential models, you can choose solar panels ranging from 10 watts to 50 watts. 

Furthermore, there are more factors to consider that are also as important when purchasing a solar attic fan, such as efficiency, materials, overall quality, and warranty: 

Efficiency: A solar attic fan is efficient and economical because it is powered by the sun and requires little to no electricity. When using renewable solar technology to power equipment in your home, you can easily save money and energy. At the same time, you are also making an environmentally conscious decision. 

Material Quality: The best solar attic fan must have the best level of safety. Your solar-powered attic fans should also be made with durable, sturdy, premium, and strong materials. This will result in long-lasting equipment that you can depend on for a long time to keep your homes comfortable and safe. 

Premium quality materials used in the making of the best solar attic fans must include:

  • Tough and adjustable solar panel
  • Seamless and flawless pure grade aluminum powder-coated housing
  • Direct current and long-lasting silent motor
  • Non-corrosive aluminum 5-wind precision balanced fan blades
  • Stainless steel protective screen

Warranty: It is crucial to choose a solar-powered attic fan with a dealer warranty or a manufacturer warranty. This can cover parts and labor in the event of equipment failure. This protection will give you peace of mind when investing. However, the warranty’s duration depends on the manufacturer. 

Remember, an established and reputable manufacturer will often guarantee the solar attic fan’s quality and workmanship. This warranty will protect you against defective units and incorrect installations. Keep in mind that once your solar attic fan has been put in place, contact your contractor to make sure that your new unit is registered for its warranty. 

Are Solar Attic Fans Worth It

It depends. 

Oftentimes, your home’s HVAC system is routed via the attic space. And even though they are insulated and are tasked to protect your whole house, it could still get extremely hot when it is in direct sunlight or during the summer season. 

This means your air conditioner passing through the duct-work is more potentially less cool after going through 30 feet or so of heated attic space. 

When this happens, it will make sense to remove most of that hot attic air. 

The most common misconception is that solar attic fans will pull cool air from your home up into the attic and outside. This is not always the case. The attic fan is pulling air from the soffit vents around your roof edges. 

You can find these vents as continuous small openings around the perimeter under the roof edges or, sometimes, separate or individual mesh vents in the soffit. 

Another benefit of having a solar attic fan is that your roof shingles are less likely to be baked from both sides. In turn, making them last longer. Cooler attics equals long-lasting roofs. 

So, to answer that question, if you live in a warm climate, solar attic fans will benefit you and your home. 

Do Attic Fans Save You Money?

Solar-powered attic fans still qualify for a federal tax credit of 30% of installation cost and your purchase. One fan cost roughly $300 to $600 plus another $100 for installation. However, most large homes need two or three solar attic fans to work more effectively. 

In places like Florida, where they get plenty of sunlight,  the typical yearly savings from putting in two attic fans amounted to 460 kWh. Depending on your standard utility and electrical bills, that is roughly around $40. Even if you install the fan, it could take you more than 15 years to get back your investment. 

Solar attic fans are more about comfort and peace of mind. These fans can make a massive difference if you use them regularly around your home. 

What Are the Pros and Cons of Having a Solar Attic Fan

  • Saves money. Since these fans help ventilate your home, reducing moisture and molds will also help lessen your home’s overall AC and maintenance cost.
