According to scientific consensus that warm air rises, and the colder air sinks. Attics are the most ideal space to store the heat inside the home. The temperature can rise to 160 degrees during hot days, even though the outside temperature is 95oF-97oF.

If an attic isn’t well protected, homeowners may face the high cost of energy as well as mold and even cold winters. A solar attic fan is one of the most effective ways to solve these problems.

Attic fans are well-known inventions. They can help cut down on the transfer of heat from ceilings to the attic air duct system.

According to the Florida Solar Energy Center (FSEC), photovoltaic fans can lower summer temperatures by up to 20 degrees. However, they’re not as effective in well-insulated attics.

Due to their photovoltaic components, they significantly cut the cost of energy as well as environmental impact. Additionally, you don’t need to be concerned about the electricity source being out of commission.

  • Roof Leaks - Roof leaks could originate from the solar fans (unless the installation is done by experts who are knowledgeable about what they do), especially if the flashing isn’t done properly. Proper maintenance is another important consideration. Take into consideration the possibility of water damage if you choose to use the vertical wall of gable used in place of the roof

A solar gable mounted on your roof could be the most effective alternative. It makes it easier to install. Installing your device on the roof, and then plugging it in is easy. It’s a lot easier as installing solar panel on attic fans in your attic.

Due to their location, gable-mounted fans are much smaller in efficiency than ceiling-mounted fans. This means that there’s a compromise. It is crucial to place your unit so that it can maximize its exposure to sunshine. Due to the gable mount it is a bit difficult, but it’s not impossible.

If you have enough room an gable-mounted solar panel is a good option for your home.


While the solar attic fans can really be durable and effective, they are more difficult to install. In order to operate correctly, you’ll need create holes on your roof to allow the fan to vent. After that, you must close the gap. This can take some time.

Due to the complexity involved in the installation of roof-mounted fans numerous homeowners hire experts to do it. Roof-mounted solar attic fans are more expensive than other options, however they’re well worth the additional cost due to their efficiency.

Despite their disadvantages, roof-mounted models are one of the most popular solar attic fans. They are more effective than other varieties.

Roof-mounted solar fans are the most effective since they get the greatest amount of sunlight. This could help to reduce the cost of the initial installation.


Portable solar fans are a great option for those who wish to travel. The panel and the fan will come in two parts that are connected. The panels are simple to install and can be placed practically anywhere.

These are ideal for attic air circulation. They can, however, be used to ventilate smaller spaces like garages or RVs. These are portable and may be carried with you well when camping or while on the move.

These are great options, but they’re not able to provide the same level of power as gable-mounted or roof-mounted solar fans. They still function well however they compromise the quality of ventilation in order to provide greater flexibility.


It is a matter of debate whether solar attic fans can help homeowners save costs on cooling.

The FSEC study shows that high-quality solar fans can provide significant cooling to the attic. This cooling impact is more apparent dependent on where you reside and the season it is. Based on the climate of their area states that have warmer climates, including Texas, California, Florida and California are more likely to experience longer cooling periods. Similar cooling benefits are observed in other states that have moderate climates in the hot summer months.

It is difficult to link the cooling benefits of upgrading the attic venting system, by installing an attic fan, as well as direct energy savings. It is difficult to calculate the amount of energy consumed due to the numerous factors to consider, including attic insulation. Other aspects to consider include home occupancy, air sealing utility bills, as well as other energy consumption reliance.

All that said that, a solar-powered fan in the attic should theoretically offer some savings in energy costs when paired with good air sealing

Insulation. Solar attic fans eliminate excess heat from an attic. This prevents heat from accumulating within the attic, and radiating into cool living spaces. You’ll feel more at ease when there is less heat entering your living space. This means you will not need additional HVAC systems, and reduces the monthly cost of your utility costs.

Solar attic fan aren’t just energy efficient, they will also help you save money over the long-term. A properly ventilated attic will reduce the chance of moisture and heat buildup. A poor ventilation system can lead to expensive mold growth and structural damage. These problems can lead to expensive repairs and remediation that can cost thousands of dollars. It’s an effective way to combat these problems by installing a ventilation system that is 100% powered by sunlight.

A 26 percent Federal Tax Credit is available for solar-powered attic fans. This credit applies to the cost of the purchase, installation, along with sales taxes. Other incentives could be provided by specific States municipalities, States or utility companies.


You should consider other factors too, as they can influence the efficiency that your attic solar fan.

You should be sure your fan buy is powerful enough to vent your attic. This can be done by comparing the fan’s ventilation power to the area.

Venting capacity refers to the volume of air being transported per minutes (or CFM). The cubic feet of your attic can be 70 percent greater over the size of the fan’s CFM.

A fan with a high power output will generate more electricity. You might need more fan to ventilate your attic if the one you’re interested in isn’t powerful enough or has enough venting capacity.
