Solar Attic Fan

Many homes can benefit from the installation of one of our several types of attic vents. Click on the product links below to learn more about each type.

Is it time to install a solar vent?

Install a Solar Power Attic Fan to improve household air quality.Solar powered fans or roof vents remove humidity and heat which allow molds to incubate.
Did you know? Deep breathing is good for houses too! Installing a solar vent in your attic or crawl space clears the air.

Fact or Fiction? A well placed solar vent will protect your health and property
 

Fact. Humidity is a culprit that eventually causes structural damage to your home and can cause major health issues (particularly respiratory difficulties). Good reasons for installing a solar powered attic fan.

Air that becomes trapped in the attic cools and mixes with hot air created from household activities such as showering, laundering and cooking to create a humid environment.

Moisture buildup in your attic creates a perfect breeding ground for mold which can cause serious respiratory and other health issues.

Molds and funguses also cause structural decay when they accumulate on wooden roof and floor supports. Mold is a toxin that must be removed immediately after it's found.

Without proper ventilation, the attic will trap heat during the summer months, which increases the money you'll spend on cooling costs.

During the winter, trapped heat will melt the snow off the roof too quickly, which will then freeze and cause dangerous ice to form on the eaves.

Installing a solar powered attic fan directs the moisture out of your enclosed areas. And that's not the only reason for installing a solar power attic fan.

Improve Attic Air quality with a solar powered fan

After having your attic or crawlspace examined for mold and other toxins, consider investing in solar vents to help circulate trapped air and prevent it from becoming too hot.

Because these vents rely on solar energy, once installed they don't need constant adjustments.

Additionally, unlike electrical vents that rely on a severe increase in temperature or moisture levels to peak before allowing the vents to open, solar vents circulate air constantly. Temperature and moisture are not allowed to rise to harmful levels before being expelled.

Types of solar powered attic fans include:

        Roof mounted solar powered attic fan.

  • Gable fans and vents
  • Solar vents for RV's, boats, and greenhouses

Each of these vents will provide you with continuous circulation of air. Depending on the size of the vent, most can operate for up to 48 hours without sunlight. Some models are thermostatically controlled.

Order special gable vents to fit them properly into existing gable vent positions. Most gable solar vents can be used for areas between 1200 sq. ft. and 2000 sq. ft. and are available in 10-watt or 20-watt units for maximum energy storage.

How does the vent get installed?

Installing solar vents is easy and doesn't cost much in terms of equipment, materials, or electrical wiring. Because the vents are powered by solar energy, they'll function for many years without any increase in your energy bill. If anything, you will see a reduction in your energy consumption, especially in the summer months because of a decrease in air conditioning needs.

Most solar powered roof vents come with a vent, fan, and solar panel that can be attached to the roof very easily with no more than a few screws. You can replace existing vents with a solar version in minutes.


 Do I need a Battery Back up?

Because these are solar powered roof vents they are most reliable in sunny areas. If you live in an area that receives very little sun in the winter or fall months, you may need to purchase solar vents that have back up batteries.

Even though most solar vents and fans can store energy from the sun for a few days, if a week or more goes by without sunlight, your solar power attic fan may stop working. Check your fans every few days to make sure they are working properly. We just listen for the hum.

How much will a solar attic fan cost?

There's really no rule on how much a fan should cost, because it depends on the installation application and the existing features of the house. Ideally, the fan is one of the last tools to be installed in a well-insulated house. The entire house needs to be properly insulated at a minimum R value of 20, which includes cold (exterior) walls, overhangs, attics, crawlspaces, basements, and generally any crevice where heat can either enter or exit the home. Once this is completed, the size of the attic must be calculated, bear in mind that most attics are a triangle shape, so use the a=(bxh)/2 method. In order for the attic to remain the correct humidity and temperature, the proper size fan much be chosen, so this is another variable that affects price. Entire house systems can range anywhere from $600 to $3,000, depending upon the factors mentioned above. Typical price includes installation by an accrediated contractor, as well as a manufacturers warranty on equipment, which may vary in length from one year to five years.

 

 What is the Bottom Line?

By replacing your existing vents with solar vents that work constantly to circulate air through your attic or crawlspace, you will reduce your chances of mold accumulation, increase the amount of time before making repairs to the roof, and your home will be protected from internal damage caused by increased temperatures and wood rot.
