Features to consider when buying a solar-powered attic fan
Solar attic fans are quite effective and easy to operate. They provide a very convenient way of adding a motorized venting system in your home with no need of having any structural changes or electrical wiring. As evident from its name, the fan employs solar energy for its operation.
These solar vents are good to help you cut down on the consumption of energy. One key thing to keep in mind here is that such fans work efficiently when there is plenty of sunlight. In lower sunlight conditions, the efficiency level of these fans is reduced as well.
Types of Solar Powered Attic Fans:
There are two types of solar attic fans, which are given below:
Roof-MountThis type of solar-powered attic fan is installed on flat or pitched roofs in your home. You also have an option to install this type in the detached garages, workshops, barns, and sheds. The benefit here with its design is that it can stand solid in case of hurricanes and tornadoes even. This is possible with no need of making any kind of panel adjustment. If any natural calamity results in the damaging of the solar attic fan panel, then it could be replaced easily with no need of reinstalling or replacing the entire unit.
Gable Mount
The Gable Mount type is installed just behind the static existing gable vent. You can mount the solar panel over the exterior wall. Such type of fans is usually larger when compared to the roof mount type. This also makes the subject fan type to receive lesser solar energy as compared to the roof mount type. The key consideration here is that the installation of a gable mount is quite technical, especially in absence of the gable vent.
Key considerations when buying a solar vent:
If you are well familiar with the technicalities of the solar attic fans then you will be able to make a smart choice with the selection of such equipment. The following key points will help you in this regard:
Flexible solar panel
When you are looking to buy a solar vent, then the key fact to consider is its flexibility. The solar panel in some cases is not adjustable at all, which raises certain issues during operation and impacts its effectiveness. The performance is deteriorated especially in those cases when the roof of your home is at a certain angle where it couldn’t receive a good amount of sunlight.
Material
The material used in the construction of the fan also drives its efficiency. The solar vent ideally should employ marine grade stuff, which is known for its long-lasting performance. Many quality manufacturers consider aircraft-grade aluminum for the housing’s hood of the fan. This helps the fan to take on the direct impact. The protective animal screen is also warranted for the solar vent, which ideally should be made from stainless steel. Finally, the vent should employ powder-coated pure aluminum flashing.
More blades mean lower noise levels
The solar attic fans are known for producing a lot of operational noise, which could be quite frustrating for the people living in the home. To keep fan noise levels to the minimum, you should choose a fan that has more blades. This is a technical thing as more blades means that each one will have lesser work to perform, thus, it will result in lower noise levels. The sound gets lower and smoother when the solar attic fan is equipped with more blades.
Motor
You must check the specification of the fan’s motor to ensure that the equipment could provide long-lasting and quiet operation. You must have a clear idea about the size of the attic that you wish to install at your home. The reason is that for a large size attic, you might need to have a couple of units to maximize the performance in such a situation.
Size of fan
The size of the fan should be in sync with the attic. This could be a challenging requirement to ensure. An active vent ideally should have the potential to recirculate as much as 10 volumes in every hour. This requires you to have the attic size in cubic feet. The simple formula to follow here is length x breadth x height measured in feet. The result then needs to be multiplied with 10 for accommodating the air changes. A piece of great advice here is to check out the specs of the solar-powered attic fan that you are considering. It will give you the cubic feet per minute number for the sake of indicating size. Divide that volume in cubic feet, which will be calculated by 60-minute for determining the size of the fan.
The whole house generators call for heavy investment and this is why you want your investment to be made for the right product. The best whole house generators from the best manufacturers come with a warranty of 3 to 5 years.
