Solar Powered Attic Fans

A ventilation system that is active, such as called the solar attic fan typically is installed on an attic roof. These devices are powered with solar panels which capture sunlight energy to generate power for fan blades. This provides constant airflow to an attic.

According to the consensus of science that warm air rises, and cold air sinks. Attics are the ideal place to store heat within the home. These spaces can reach 160 degrees during hot summer days , even if the outside temperature ranges from 95oF-97oF.

If your attic isn’t insulated, homeowners can experience the high cost of energy, mold growth, and cold winters. Solar attic fans are one of the best options to tackle these issues.

Attic fans are a well-known invention. These devices can reduce the transfer of heat from ceilings to in-attic systems for ducting.

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

Due to their photovoltaic components this can significantly cut down on the cost of energy as well as environmental impact. In addition, you don’t have to worry about your energy source failing.

  • Low Monetary Savings - One year of testing solar fans led to a 1000 square foot house that was air-conditioned. It conserved 460 kWh of energy. It’s a savings of only $40 per year.
  • Roof Roof leaks can result from solar fan (unless the installation is done by professionals who know their stuff), especially if the flashing isn’t done properly. A proper maintenance program is an additional aspect to consider. Be aware of the risk of water damage if an gable-wall vertical is used as opposed to the roofing

It is time to decide which is the best match for your house. The layout of your home and the design will decide the type of solar attic fan that you select. We’ll go over the three kinds of solar attic fan in this article.


A solar fan mounted on gables on the roof of your house could be the best option. This makes installation easier. Installing your device on the roof, and then plugging it in is simple. This is far less difficult to install solar panels attic fans in your attic.

Due to their position Gable-mounted fans are smaller in efficiency than ceiling-mounted fans. In the end, there is a tradeoff. It is crucial to set your unit correctly in order to maximise its exposure to sunlight. Due to the gable mount it is a bit difficult, but it’s not impossible.

If you have room, a gable-mounted solar fan is a good option for your home.



While these solar attic fans are able to be powerful and reliable however, they can be more difficult to install. To get it to work properly, you’ll have to create holes on your roof to let the fan vent. Then, seal the gaps. This can take some time.

Due to the complexity with installing roof-mounted fans numerous homeowners hire experts to install them. Roof-mounted solar attic fans are more expensive than other approaches, however they’re worth the extra money because of their effectiveness.

Despite their shortcomings, roof-mounted models are one of the most popular rooftop fans that are solar powered. They are more effective than other types.

Roof-mounted solar fans are the most effective since they get the greatest amount of sunlight. This may help offset the expense for the first installation.


Portable solar panels are a fantastic alternative for people who want to be mobile. The panel and fan will come in two parts that are wired together. The panels are easy to install and can be placed practically anywhere.

These are ideal for attic ventilation. They can, however, be used to ventilate small spaces, like RVs or garages. These are portable and may be taken with you well when camping or on the go.

These are great attributes, however they’re not able to provide the same level of power as roof-mounted or gable-mounted solar fans. These fans are still effective but they do not have the same ventilation to allow for greater versatility.


There is a disagreement whether solar attic fan can save homeowners cash on cooling.

The FSEC study demonstrates that high-quality solar fans can bring significant cooling to the attic. This cooling impact is apparent in the region you reside and what time of year it is. Based on their climate, states with warmer climates, like Texas, California, Florida and California, can experience longer cooling periods. Similar cooling benefits are observed in other states that have moderate climates during the hot summer months.

It is difficult to link the cooling benefits of improving the attic venting system by installing an attic fan, and direct energy savings. It’s hard to estimate how much energy is consumed because there are so many factors to consider, including attic insulation. Other factors to take into consideration are the occupancy of your home, air sealing, utility bills, and other reliance on energy.

However that, a solar-powered fan in the attic might theoretically be able provide some energy savings when combined with air sealing that is good.

Insulation. The solar attic fan removes excess heat from an attic. It prevents heat from building up within the attic, and radiating out to warmer living areas. You will feel more comfortable if there is less heat radiating into your living area. This will reduce the need for additional HVAC systems as well as lowering your monthly energy bill.

Solar attic fans aren’t only energy efficient, but will also help you save money over the long-term. A proper ventilation system for your attic can reduce the risk of heat and moisture accumulation. An inadequate ventilation system could cause costly mold growth as well as structural damage. These issues can result in expensive repairs and remediation that could cost thousands of dollars. It’s a smart way to combat these problems by installing a ventilation system which is completely powered by sunlight.

A 26 percent Federal Tax Credit is available for solar-powered attic fans. This credit applies to the cost of purchase, installation, as well as sales tax. Other incentives are provided by specific States municipalities, states or utility companies.


There are other elements to take into consideration too, as they can affect the efficiency of your solar attic fan.

You must be sure that the fan you purchase is powerful enough to vent your attic. You can do this by comparing the fan’s venting capacity with the space.

Venting capacity refers to the volume of air being transferred every minute (or CFM). The cubic feet of your attic is 70% larger than the fan’s CFM.

A fan with a high wattage will produce more electricity. You may need additional fan to ventilate your attic, if the one you’re interested in does not have enough wattage or capacity to vent.

If you are interested in specific features like a thermostat or humidistat make sure they are included in the model prior to you purchase it.
