  The Cost-Effectiveness of Solar Ceiling Fans  

During summer, the temperatures in your home could reach a very uncomfortable and stifling level. That is why many homeowners incur exorbitant electric costs during summers because their fans or air conditioners work overtime to provide cool air.

Plus, solar fans are available in interesting designs and styles that will complement any modern, contemporary home. Take a look at some solar ceiling fans that may interest you.

Solar Attic Fan

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 Fans to Reduce Heat Gain From Cathedral Ceilings

Solar fans have simplified attic ventilation. Having been in the business of ventilating attics for almost thirty years, one of the most difficult (and, in fact, impossible) situations to deal with in completed construction is heat buildup in completed rooms or finished attics with “up to the peak” cathedral ceilings. If you’re an architect, builder or homeowner considering cathedral ceilings, I have recommendations you might consider. The present theory, as reflected in most building codes, is that hot air will travel by convection from the soffit vents, through the styrofoam spacers and exit through the ridge vent.

Our experience has been that this theory does not work very well. In fact, the air below the roof can reach temperatures in excess of 150 DegF. That hot air is rapidly expanding. Unable to escape through the ridge and soffit vents quickly enough, it pushes through the porous insulation, heating up the ceiling and creating a tremendous heat gain to the living area. Very often, even a well-designed A/C system can’t keep up.

SUGGESTION: Design a small attic over the cathedral ceiling. A solar-powered roof fan will exhaust heat from the “attic”, creating a vacuum, thereby pulling in cool air from the soffits through the spacers. This creates an envelope of cool air around the living space, (If you already have some flat ceiling, just add a solar fan).   .

These heat gain forces are the same in a regular stand-up attic. The solution is the same.

The living area with cathedral ceiling will be AT LEAST 10 DegF cooler with proper insulation, soffit vents and a solar roof fan, without the A/C turned on.

Please note: insulation contractors should ensure unobstructed airflow from soffit vents to attic.

Solar powered attic ventilation is one of the most cost-effective ways to improve energy efficiency for air conditioning and to improve LEED score. Typical installed cost is about $550 after tax credits are applied. Federal Energy Tax Form 5695. Energy saving and carbon footprint for cooling can be reduced by 10% to 30%. Payback time is less than 5 years. Every succeeding year is money in the bank!

Architects would be well advised to include and specify quality solar fans during the design phase of a project. We have many request from townhouse style condo owners because the upper floors of the unit are warm, even with the A/C turned on. They are prevented from taking remedial action because they can’t get permission from the Condo Association Committee.

A minimum 10% reduction in energy usage (and proportional reduction in carbon footprint) for cooling is a huge number. Moreover, it’s most effective at the exact time when the stress on the “grid” is the greatest, during hot weather. Cost saving to the utility company by not having to upgrade their infrastructure because of reduced peak demand is substantial.
