Solar Powered Fan Attic – $ 399.00 |
Attics are an important part of the house and therefore need to be kept clean and cool as a warm and moist attic can make the entire house warm. Therefore venting of the attic is extremely important and attic fans are very useful for the purpose.
Venting of the attic in the proper manner extends the material life and keeps the attic cool. This in turn reduces load on the air conditioning system of the house. Circulation of fresh air is increased and vapor generated by daily activities is reduced significantly.
Moisture that remains trapped in the attic is very harmful not only for the attic but the entire house. It leads to the build up of mold and bacteria which can hamper the freshness of the air. This can lead to respiratory disorders. Therefore attic venting is an important aspect that must be taken care of.
Solar attic fans are the best solution for the venting of the attic. Using the solar power entirely, these solar fans provide worry and maintenance free cooling of the attics. Maintaining the circulation of fresh air, these solar fans are available on amazon.com. There are many models of the solar attic fans on offer and each has its own unique features and benefits.
Some of the features of the solar attic fans as provided by amazon.com are:
? As the name implies, these solar attic fans are entirely powered by the sun
? The fans reduce the heat and warmth from the attics, thus in turn keeping the entire house cool. This further reduces the load on the air conditioners leading to savings on electricity bills.
? Environment friendly products
? Maintenance free
? Cooling at no cost since sun powers the fans
Uses of the solar attic fans:
During summer months: the attic temperatures during the summer months can rise dramatically leading to the entire house being hot and humid. Passive roof vents are not able to dissipate the heat adequately. Thus solar attic fans are the right product for such conditions.
During winter months: during the winter months when ice settles on the roof, the air trapped in the attics cause it to melt and trickle down. When the ice reaches the cooler eaves it again freezes, leading to ice damming which is not only costly but destructive too. Therefore fans for the attic are helpful in maintaining a warm temperature during the winter months.
During normal weather conditions: besides the extreme weather conditions, temperatures in the attic usually remain high as the daily chores like cooking and showering produce vapor which if not dissipated correctly can lead to moisture remaining in the attic. This can lead to rotting of the wood and rusting of the iron. Therefore fans in the attic are helpful in maintaining fresh air and preventing such problems
Amazon.com has a wide variety of such solar attic fans and one can choose from the model and make as required. You can easily find fans for more than 20% off that will be shipped right to your door.

Solar Attic Fans – DIY Renewable Energy You Can Afford!
I hear all too often that people are hesitating to move towards renewable energy because of costs. There are a number of small changes you can make that are not expensive that will make a huge change in your home’s overall efficiency and comfort. A solar attic fan is one of the easiest and most effective renewable energy investments you can make in your home.
Why would you use a solar attic fan?
Well, many people already use exhaust fans in their peaked attics or crawl space. The air in these spaces becomes very hot, and by conduction, that heat passes through to the rooms below. This can increase the need for air conditioning and other energy using cooling methods or just make your house hotter during the summer which is uncomfortable. By exhausting the hot air, you reduce conduction and keep your home cooler consequently reducing power consumption in cooling.
In the fall, winter and spring, solar attic fans can also improve ventilation and reduce moisture in the air of your attic which protects anything you have up there as well as your insulation which will be far more effective when dry and well ventilated. Normal attic fans are wired into the AC power of your home while solar attic fans take their power from the very sun that is heating your attic air. If you already have a traditional attic fan in your home, a solar attic fan is an easy investment that will save you money in the long run and set a great example to others in your community.
Depending on your roof configuration, you’ll be able to find a solar attic fan that will meet your need. Some units are self contained and have the fan and the solar panel in the same unit and must be roof mounted while others are designed for separate installation – meaning the solar panel can be mounted in one location and the fan can be mounted in another.
Solar attic fans are absolutely feasible for most DIY enthusiasts. There are several things you need to take into consideration before choosing the solar attic fan for you.
If your roof peaked or flat?
Is your home oriented properly for solar exposure?
Do you have non-shaded area for the solar panel mount?
Do you have a proper air intake to offset the air being blow out (you don’t want a vacuum)?
Solar attic fans run in cost from $300 to $600. If you have someone handy in your home, they can probably complete the entire installation – in face this is a great starter project for renewable energy enthusiasts. You can also have solar attic fans installed by a professional contractor, roofer or handyman if you are so inclined. So if you’re looking for a quick, inexpensive and fairly easy way to make your home more efficient for the summer time, then consider a solar attic fan! Your home will be cooler, your attic will be dryer and more comfortable and you won’t be using any electricity to make it happen!

Solar Attic Fans
Easily installed and free to operate, solar attic fans are a smart choice for homeowners who want to save money cooling their homes in summer, prevent ice dams in winter, and extend the lives of their roofs.
Operating Principle
A solar attic fan uses photovoltaic panels to convert sunlight into electrical power. The electricity generated is used to turn a fan motor, exhausting air from the attic of a home.
Benefits
In summer, temperatures in an unventilated attic can exceed 160 degrees F. A properly sized solar attic ventilation system will reduce attic temperature to 5-10 degrees F above the outdoor temperature. Ventilating the attic reduces the amount of heat transferred from the attic to the home, decreases the load on the air conditioning system (reducing your electric bill), and extends the life of the roof.
In winter, heat trapped in the attic may melt snow on the roof, which trickles down and creates destructive ice dams in the colder eaves.
The attic becomes warmest when the sun is the strongest. A solar attic fan runs the hardest when the sun is strongest.
Everyday home activities such as cooking and showering create moisture which collects in the attic and promotes mold and mildew growth, reduces the effectiveness of insulation, and attacks the wooden attic structure. Year round fresh air circulation from a solar attic fan removes this moisture and prevents moisture related problems.
Zero operating cost.
Installation can be done by a handy homeowner. No electrician is required.
Quiet operation.
Things to Consider
· The cost savings due to reduced air conditioner load depends on the price of electricity in your area, the amount of attic space in your home, the efficiency of your attic insulation, and the amount of ventilation your solar attic vent is able to provide. A typical installation will usually pay for itself in savings within 1-2 summers of use.
· A solar attic fan should not be used when air from the living areas of the home can freely enter the attic. This would result in conditioned air being removed from the home. Any openings between the attic and the home should be sealed before a solar attic fan is installed.
· Properly sized attic vents are required to allow fresh air to enter the attic and replace the hot air removed by the solar attic fan.
· Solar attic fans should be mounted away from ridge vents and gable vents.
Configurations
Solar attic fans are available three configurations:
1. Self flashing roof solar attic fan: The fan base is flat and designed to slide under shingles and attach directly to the roof.
2. Curb mounted solar attic fan: The fan base is a cap designed to fit over a curb which is attached to the roof.
3. Gable fan: The fan exhausts horizontally through the gable end of the attic.
In addition, solar attic fans are available with fan mounted or remote solar panels.
Installation Overview
1) Cut hole in roof (South side is recommended), taking care not to cut through any roof framing members.
2) Slide unit under shingles
3) Reshingle around fan as necessary.
Commonly Asked Questions
1) What size fan do I need?
ANSWER: A solar attic fan should be sized to provide 10 attic air volume changes per hour.
To figure out what flow rate this works out to, figure out the volume of your attic in cubic feet. Multiply your attic volume x 10 air changes per hour to get the total flow required per hour.
Since fans are sized in terms of their cfm (cubic feet/minute) output, divide your total flow per hour by 60 to get cubic feet per minute.
Required flow rate in cfm = (attic volume x 10) / 60
Now check the fan specifications to find the fan or combination of fans required to meet your ventilation needs.
It is also very important to make sure there is enough air inlet area in your attic to allow fresh air to enter and replace the hot air being exhausted. A minimum of 1 square foot for every 360 cfm of exhaust is required. Typically soffit vents are used as inlets.
2) How long will a solar attic fan last?
ANSWER: Solar attic fans are designed to provide many years of trouble free operation. The length of manufacturers’ warranties are a good indicator of the high standards these fans were designed to:
Attic Breeze Fans – Lifetime parts warranty
Solar Star Fans – 5 Year parts on solar panel and motor, 10 years on all other parts.
Natural Light Fans – 25 Year parts warranty
SunRise Solar Fans – 5 year parts warranty on motor, 10 years on all other
3) How is a solar attic fan controlled?
ANSWER: A thermal switch is often used to control a solar attic fan. This switch only allows the fan to run when the attic is warmer than 80-90 degrees F. Running the fan only when the attic is hot extends the life of the fan motor and results in less heat loss to the attic in winter, but does not allow the fan to reduce moisture build-up in the attic at all times and does not allow the fan to prevent ice dams during the winter.
