Solar Powered Attic Fans

A ventilation system that is active, such as known as the solar roof fan, is usually placed on the roof of an attic. These fan blades are powered by solar panels which capture sunlight energy to drive fan blades. This provides constant airflow to an attic.

According to the consensus of science, warm air rises and cold air sinks. Attics are the most ideal space to store heat in a house. They can be heated to 160 degrees during hot summer days even though the outside temperature is 95oF-97oF.

If your attic isn’t insulate, homeowners could face expensive energy bills along with mold growth and cold winters. A solar attic fan is one of the most effective ways to tackle these issues.

Attic fans are well-known inventions. They can help limit the transfer of heat from ceilings to in-attic systems for ducting.

According to the Florida Solar Energy Center (FSEC) photovoltaic fan technology can reduce summer temperatures by up to 20 degrees. But, they are not as effective in attics that are well-insulated.

Due to their photovoltaic components, they significantly cut the cost of energy as well as environmental impact. In addition, you don’t have to worry about the power source going out.

Solar attic fans are recommended for homes with issues with insulation.

The solar attic fan efficiently removes warmth from attics. This will preserve your roof and heating system while improving the comfort in your home.

The solar attic fan can ensure that your attic stays clean. They do not just extract warm air from your roof and allow it to cool, but they can be able to operate without power, saving you cash on your utility costs. It’s a long-lasting, efficient, and effective choice.

An attic solar fan is a smart investment. Before you upgrade the ventilation system in your attic, first pick which solar fan is ideal for you. There aren’t two attic solar fans that are the same, so you will have to take into account the layout of your house.

Advantages and Disadvantages of Solar Attic Fans

Attic fans can be utilized to cool the attic in summer or remove roof moisture in winter. Solar attic fans offer more benefits than the powered models. Solar attic fans could be the best option for you. Here are the best 15 pros and cons.

Pros

There are plenty of great features to consider when buying a solar fan in your attic. Here are some positive points in the discussion about the pros of solar-powered attic fans and cons.

  • Installation is free of cost - There are no ongoing costs after your solar attic fans are installed, unless it is an emergency. Solar attic fans will not raise your electric bill.
  • Lower Attic Temperatures – Using the solar attic fan could be an excellent option for managing heat particularly in summer, when temperatures can reach the 130 degree mark. It can truly aid in the reduction of the heat.
  • They won’t steal cool air from the Rest of Your House Do not be concerned that solar fans may steal cool air out of your house. Solar fans won’t take cool air out of your house. However, powered attic fan could suck cool air out of your house, making the air cooling work more efficiently.
  • Noise is not a problem - The noise of solar attic fans is nearly as low as that of powered fans.
  • There is no need for electricity - A solar attic fan gets its power from the sun so it doesn’t require an electrician. However, electric fans can get burned out and can become dangerous fire hazards.
  • There is no risk from carbon monoxide – Powered attic fans with their power can generate negative pressure zones that pull carbon monoxide from combustion devices to the attic. The carbon monoxide risk from solar attic fans is not present.
  • Save Your Roof The winter heat rises to the attic. Solar attic fans draw the heat and moisture from the attic aiding in preventing damage to your roof caused by mold, wood rot and the expansion of ice. It can also prevent the dripping of ice.
  • Cool the surrounding areas - Temperature of areas closer to the solar fan is significantly less.
  • Earth-friendly - The planet is better when it is powered by solar energy. It is possible to make a difference in the future by choosing sustainable energy sources over other forms of power. We invite you to visit our website to learn more about sustainable energy sources.
  • Visually more appealing Solar attic fans are more obscure than attic fans powered by electricity. They are more visible as well as less distracting the alternatives. This is the reason solar attic fans are extremely well-known.

Cons

Although solar attic fans provide numerous benefits but they also have negatives. Here are some of the disadvantages of solar attic fan.

  • Less Efficient if Overcast - Sun energy isn’t always the best, especially after the sun sets. The house will still be hot regardless of whether it’s under sun’s rays.
  • Low Monetary Savings - One year of testing solar fans led to a 1000 square foot house with air conditioning. It saved 460 kWh of energy. It’s a savings of just 40% per annum.
  • Roof Roof leaks could originate from the solar fan (unless they’re installed by experts who know what they do) particularly if the flashing is not properly done. Maintaining the roof properly is another crucial factor to take into consideration. Take into consideration the possibility of water damage in the event that you choose to use the vertical wall of gable is used instead of the roof
  • The price is high – A typical solar-powered attic fans costs about 600 dollars and is installed for between $150 and $300. Multiple solar attic fans may be required to power your house.
  • Low air movement Solar attic fans can move more air than powered fans. Solar attic fans might not be as powerful as powered ones and therefore they might not move as much air from your attic.

THE BEST SOLAR ATTIC FANS

It’s time to choose which one is the most suitable to your home. The layout of your home and the construction will dictate the type of solar attic fan that you choose. We’ll be discussing the three types of solar attic fan in this article.

GABLE-MOUNTED

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

Because of their positioning Gable-mounted fans are less efficient than ceiling fans. This means that there is a tradeoff. It is crucial to set your unit correctly in order to maximize the amount of sunlight it gets. Due to the gable mount this can be a bit difficult, but not impossible.

If you’re in a space that’s adequate for a solar fan mounted on gables, it could be the best option for your house.

 

ROOF-MOUNTED

While the solar attic fans can really be durable and effective however, they can be more difficult to set up. To get it to work correctly, you’ll need drill holes in your rooftop to let the fan vent. Then, seal the gaps. This process may take a while.

Due to the complexity involved in the installation of roof-mounted fans numerous homeowners hire experts to install them. Solar attic fan roof-mounted are more costly than other methods, but they’re well worth the additional cost due to their efficiency.

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

Roof-mounted solar fans have been the most effective since they are the ones that receive the most sunlight. This may help offset the expense of the initial installation.

PORTABLE

Portable solar fans are a great option for those who wish to move around. The panel and the fan will be provided in two pieces connected. These panels are simple to set up and can be put in almost any location.

These are ideal for attic air circulation. They canalso be used to cool smaller spaces like garages or RVs. They are portable and can be brought with you as well as camping or while on the move.

They are all fantastic features, but they’re not able to provide the same amount of power as gable-mounted or roof-mounted solar fans. These fans are still effective however they compromise the quality of ventilation in order to provide greater flexibility.

SOLAR POWERED ATTIC FAN HELPS YOU SAVE MONEY

It is a matter of dispute whether solar attic fans are able to save homeowners money on cooling.

The FSEC study shows that top-quality solar-powered fans can deliver significant cooling to an attic. This cooling impact is more apparent dependent on where you reside and what time of the year it is. Based on their climate states with warmer climates, including Texas, California, Florida and California are more likely to be subject to longer cooling periods. Similar cooling benefits are observed in other states with moderate climates in the hot summer months.

It is difficult to link the cooling benefits of the upgrade of the attic venting system, by installing an attic ventilator, and the direct energy savings. It’s difficult to determine how much energy is consumed due to the numerous variables, such as attic insulation. Other elements to consider are home occupancy, air sealing, utility bills, and other reliance on energy.

In the end the solar fan that is installed in the attic might theoretically offer some energy savings when it is paired with good air sealing

Insulation. Solar attic fans eliminate excess heat from an attic. This stops heat from building up within the attic, and radiating out to warmer living spaces. You’ll feel more at ease when there is less heat radiating into the living space. This will reduce the need for other HVAC systems, and reduces your monthly utility costs.

Solar attic fan aren’t just energy efficient, they could also save you in the long run. A proper ventilation system for your attic reduces the risk of heat and moisture accumulation. Poor ventilation systems can lead to costly mold growth as well as structural damage. These problems can lead to expensive repairs and remediation that can cost thousands of dollars. It’s an effective method to tackle these issues with a ventilation system which is completely powered by sunlight.

A 26 percent Federal Tax Credit is available for solar-powered attic fan. This credit applies to the cost of the purchase including installation and sales tax. Other incentives could be offered by certain States municipalities, States, or utility companies.

OTHER FACTORS YOU SHOULD CONSIDER

There are other elements to take into consideration as well, which can affect the performance the solar attic fan.

It is important to make sure that the fan you buy can withstand the pressure of venting your attic. You can do this by comparing the fan’s ventilation power to the space.

Venting capacity is the volume of air being transported every minute (or CFM). The size of your attic’s cubic feet can be 70 percent larger over the size of the fan’s CFM.

A fan that has a higher power output will generate more electricity. It is possible that you will require more air vents for your attic the one you’re looking for does not have enough wattage or venting capacity.

If you’re interested in specific features like the humidistat or thermostat, ensure that they come in the model prior to you purchase it.
