How to Buy a Solar Attic Fan

Solar attic fans can be a great way to ventilate your attic and save money doing it by using solar power. The benefit of a solar attic fan is that it makes your living spaces much more comfortable in those hot summer months while reducing cooling costs. Aside from the summer use, a solar attic fan can also prevent ice damming in your attic by allowing moisture buildup to escape.

Instructions

- 1
  Estimate the cooling needs of your attic considering its size. When deciding on a solar fan model, you need to have a rough estimate of the square footage of the attic, to be able to decide the size of the fan, in terms of wattage.
- 2
  Consider the materials. Make sure to choose a solar attic fan that will not rust. This depends on how long you want your solar attic fan to last. Better materials add to the price, but will pay dividends in the future.
- 3
  Select a fan that comes fully assembled. Trying to assemble the solar attic fan can take a significant amount of time; look for models that come assembled, so your only job will be to install the fan on your roof.
- 4
  Consider the noise the fan makes. It will do you no good to install the fan only to find that you have to live with the sound of a jet engine over your bedroom. Look for a quiet solar attic fan.
- 5
  Look for a leak proof flashing on your solar attic fan. Seamless or one-piece models are the best because you want to avoid leakage on your solar powered attic fan. This allows the fan to function at its best year after year, without any costly repairs.
