Solar Attic Fan: A Real Money Saver you can build and Use for up to 25 Years

A Solar Attic Fan is a device to lower the temperature in your attic by as much as 50 degrees allowing your air conditioner to work less. It is simple and one of the best solutions that can protect your home and save you money. Powered completely by free solar energy, it is compact, quiet and efficient!

How it functions; types available

 Solar Attic Fan functions by blowing out hot air and moisture out of your attic and pulling in cooler air from the outside thus improving attic air circulation and resulting in a healthy and energy efficient home.   Minimizing the temperature difference increases the overall efficiency of your home’s insulation and reduces the amount of heat transferred into your home.

Highly efficient, a 10 watt attic fan can move 850 cu. ft. of air per minute; a 20 watt fan, 1250 cu. ft. Cost ranges from $ 400 to $ 600 if you buy. It could be very much less if you build one. The unit consists of housing, motor and panel.  Most Solar Attic Fan available carries a warranty of 25 years.

Benefits and advantages

By lowering attic temperatures and reducing heat transfer, your home will feel more comfortable and will require less energy to cool.  It will exhaust super heated attic air before it can get into your living space. Solar Attic Fan will surely reduce your air conditioning expenses. 

It can also reduce moisture that decays wood and insulation. It helps extend the life of your roof.  In summer months, it keeps your attic cooler helping reduce the load on your air conditioning system. In winter months, it prevents moisture build-up and ice damming.  Adding a Solar Attic Fan is a simple and affordable home improvement that will pay for itself overtime.

Advantages of Solar Attic Fan over conventional fans:

1.       Free energy to power fan; it comes from the sun
