Attic fans can be bought at different wattages ranging from 10-15 watts to up to 36 watts. You need to buy a fan which will be ideal for the size of attic you have.
10-15 watts are enough for areas of up to 1,200-1,600 square feet, while fans of 25 watts can easily handle attics of up to 2300 square feet.

Nature of Roof

There are some models that cannot be installed on specific kind of roofs. For example, the rank one solar attic fan in our list is not suitable for mounting on flat roofs.

So you need to be aware of the design and build of your house to purchase the perfect fan. Sometimes you can fit them with additional accessories on incompatible roofs.

Fan Features

So, what are the solar attic fan features that you need to be looking for? Here is a look at what you need to look at when zeroing in on your fan choice.

  • Fans with five aluminium blades are best for efficiency and savings. They need to rotate less to attain the desired speed and hence the results.
  • Some models are equipped with solar panels that can be adjusted to certain degrees to get the maximum sun exposure.
  • Birds or pests can enter the motor of the attic fan and damage it. That is why you must look for stainless steel or mesh protection for preventing such cases.
  • It is better to avoid attic fans which are made of low quality plastic parts. They will not be able to withstand extreme weathers like hail or storm reducing the return on your investment. Heavy duty aluminium fans are the best when it comes to durability and longevity.
  • In-built thermostats are great advantages which ensure that your fan is working only when required. So look for products which are equipped with one.
  • Attic fans can start producing noise after they have been in use for some time. Look for models which have a guarantee of quiet motor backed by the company.

Not all solar attic fans carry the same warranty. Generally the brands come with separate warranties for the motor unit and the solar panel.

In our reviews you have seen warranties can range from anything from 1 year to lifetime. Make sure that you at least have 5 years warranty on the fan and in case of the solar panel, make it a minimum of 10 to 15 years.
