Factors to Consider Before Buying A Solar Attic Fan

There are several factors that you need to carefully consider before buying a solar attic fan. Here we are going to discuss each of them in detail –

Now combine this with the tilt adjustment feature and the solar attic fan will be able to run for a longer period of time.  

2. Size of Fan and Solar Panel

Don’t go for a jumbo size solar powered attic fan. That would eat up too much space on the attic. Moreover, a large attic fan might have a negative impact on the overall aesthetic of your house. And it does not end there; if the fan blades are large, you are going to have a hard time positioning it properly under the sun. You need to find a solar-powered attic fan that has extended cord.

3. Noise

So, while purchasing a solar-powered attic fan, you need to make sure that the fan does not make loud noises without making any kind of compromises on its cooling capabilities.

4. Quality Materials

Solar power fans have to deal with extreme heat, storm and other extreme climatic conditions and that means, they need to be made from high quality and durable materials otherwise they would not last long. The blades should be ideally made from non-corrosive aluminum. To scare away the birds and other wild animals, the solar attic fan needs to have a stainless steel protective screen.

5. Attic Space

The attic’s square footage and the overall venting capacity of the attic are the two factors that can play a pivotal role when it comes to selecting the right solar attic fan.

The attic of a typical house tends to get super-hot during the day. It is insulation which is primarily responsible for this buildup of heat. By installing a solar attic fan, you will be able to extract warm air from the attic. This process will cool down the place significantly. However, this process is not as it transpires to be. There are a number of factors in play. For example, you need to take into consideration the attic venting load requirements before installing a solar-powered attic fan. If the solar-powered attic fan does not meet the requirements, it means that it will be a gigantic waste of time and effort on your part if you wish to continue with your aforementioned plan.

Regulating the temperature of the attic is not that complicated but of course, you will need to have a better understanding of the venting capacity of the attic otherwise a disaster is just waiting for you around the corner.

6. Tilt Adjustment

The tilt angle of the solar panel should be adjustable in nature otherwise you could be in for a lot of trouble. You need to realize the fact that you might not get the ideal slope to get the maximum amount of sunlight and in that case, changing the tilt angle of the Solar panel of the attic fan could save your day. Otherwise, the solar attic fan would never be able to perform at an optimal level.  

7. Accessories

Humidistat and thermostat can come in handy as they help to regulate the switching mechanism of the attic fan. To make sure that the solar attic fan installation completely weatherproof, you need to have either a tile roof flashing skirt or fire safety cutoff switch.

8. Mounting Type

In case, you hate the idea of cutting a hole in the roof of your house, you will have to settle with a gable mount attic fan. However, installing a gamble mount solar fan will take some doing. But on the other hand, installing a roof mount solar attic fan is comparatively easy.

9. Ease Of Installation

You would definitely not like the idea of spending hundreds of dollars on installation of the solar attic fan. That would make no sense whatsoever. This is the reason why you need to read the installation manual provided by the manufacturers before making the final buying decision. Ask yourself first – can I do this myself or do I have to ask a professional to get this installed on the roof? Solar-powered attic fan with simple installation process should be given preference at any cost.
