Solar Attic Exhaust Fans Are Uncomplicated DIY Projects

Posted by cheapsolarcells on June 5th, 2010

Are you looking for a fast and uncomplicated solar panel energy project for your home that you can do by yourself? Installing a solar attic fan may be just the ticket. Not only is it moderately easy to do, but it will keep your house cooler during hot summer days and nights.

You may not have even realized how much a sweltering attic contributes to your air conditioning bills. Attics trap and hold all of the hot air that rises in your house. This is wonderful in the winter, but it can inhibit your house from cooling off during the summer.

Attic temperatures can easily climb above 120 degrees Fahrenheit even when outside temperatures are only in the eighties or nineties. Most building codes require attics to be vented, but these vents are simply not intended to cool off the entire attic. And a roof that has no shade gets sun for a large amount of the day.

Installing a conventional attic fan would require a licensed electrician because it would need to be attached to a power source in order to work. But solar attic fans are constructed with built-in pv (photovoltaic modules powerful enough to run the fans. Not only are they quieter than electric attic fans, but they require no electricity to run since they are installed on the roof and receive direct sunlight.

If you are handy with a saw, drill and screwdriver, and self-confident enough to cut a hole in your roof, you can install a solar attic fan in a couple of hours. You will need to locate a place on your roof that receives sunlight the entire day, is close by the peak and also near the middle of the attic space. You will be cutting a hole through the composition shingles and roof decking that will accommodate the size or your solar fan.

The toughest and most important part will be finding the optimal position and cutting the hole the proper size for the fan. A location that faces south will receive the most sunlight. If that is not doable, you can consider buying a model that has a solar module that can be tilted and positioned to face south.

Once the hole has been cut, it is only a matter of securing the solar attic fan to the roof, and caulking around the fan to waterproof your installation. You will be able to right away be aware of the cooling effects in your attic. Also you will be able to have a more comfortable house and lower cooling bills throughout the summer.
