solar roof ventilation fan

Solar Roof Ventilation Fan Outdoor Extraction Fan Home or Shed with BONUS 150mm EAVES VENT

Whirly birds can only exhaust around 100CBM (Cubic Metres) of air per hour while the SolarKing 320MM solar fan can pump 2100CBM of air per hour, more than 20x the air movement. This makes the SolarKing far more effective keeping your home or business cooler. You can even use multiple solar roof fans on larger or two storey homes. The SolarKing 320MM solar fan can be easily mounted on either tile, Colorbond or flat roofs. The unit also has an adjustable tilt solar panel for use on non north facing roofs or flat roofs. The SolarKing exhaust fan consumes free solar energy, which means no running cost ever. Also by reducing your roof temperature, your reliance on your air conditioning will reduce and lower your energy bills. The SolarKing exhaust fan can be self-installed or you can use one of our approved installers to do the job for you. For tiled roof installations, only 1 tile needs to be removed and for Colorbond roofs, just a 300mm opening needs to be cut.

The brushless DC motor provides long life, quiet operation and high efficiency.

Solar Roof Ventilation VS Whirlybird

an article by Declan Reynolds

While building a new home or renovating the current one- the most obvious question that comes to mind is – whether a solar roof vent or whirlybird is better. Well, if you’re also stuck in some such situation where you are not able to make out whether to go with solar roof vent or whirlybird, then this post is for you. Here in this post, I am trying to share with you all about both the options, so that making decisions is easy for you……

Here we go………

Let’s start with Whirlybirds

Of course, whirlybirds are the most common form of roof ventilation as they’re cheap and are easy to install. But the question is – is that all you are looking for? I am sure that’s not enough!

Undoubtedly, whirlybirds are cheap and their installation is also cost-effective, but it is highly unlikely that a single whirlybird will provide sufficient ventilation at your home or workplace. Only if you have an adequate number of whirlybirds (one or two whirlybirds are not going to work unless your home is very small), they may provide an appropriate amount of ventilation and cooling. Which simply means you will need many whirlybirds in order to make an impact on energy efficiency, but that will increase the cost automatically.

Another issue with whirlybirds is – in winters whirlybirds do not maintain the heat of the room. Actually whirlybirds are designed in such a way that they lose heat in winters, which will ultimately increase your electricity bills during winters as you will end up using heaters and other electrical equipment.

Because of the same flaw, whirlybirds do not provide enough cooling during the summer months as well, as they don’t work without enough wind. So, during hot summers when the weather is very hot and there is no wind, whirlybirds will be next to useless as they won’t extract hot air from your home. However, there are whirlybirds which are designed specifically for the time when there is no wind, but these whirlybirds run on the turbine and are pricey.

Solar Roof Ventilation

Solar roof vents, on the other hand, offers guaranteed long term advantages. How you ask? Here is how…….

Solar roof vents simply extract hot air in your attic through the roof vents. They basically help you keep your home cool during the summer season, lower your energy consumption, and keep your attic ventilated. Solar roof vents allow cooled outdoor air to fill your home through eave vents. That means your air conditioner no need to work so hard to cool your house. For instance, if it takes your air-con around 10 mins to cool your house, now after installing solar roof vents it takes only 5 mins to cool the same house. It reduces the pressure on your ducted air conditioner and makes it work efficiently. You only need to turn your AC on when its more than 35 degrees outside. Moreover, you don’t get any cosy and stuffy nights due to humid weather and your house naturally cools down at night when you extract all the roof cavity at day time with solar roof vents.

A solar roof vent helps to reduce moisture and humidity indoors, thereby keeping your house cool in summer and hot and cosy in winters. Believe you me, having solar roof vent at home will help you have the best summers indoors!!

Unlike whirlybirds that can extract only 100 cubic meters of air per hour, solar roof vents can extract up to 2100 cubic meters of air per hour. It simply means that one solar roof vent is equivalent to 20 whirlybirds.

A solar roof vent system comprises of small solar panel that is used to feed power to a fan that is fitted inside the frame. Unlike a typical whirlybird, solar roof vent panels get activated the moment internal roof temperatures goes above 25 degrees Celsius.

Another most important benefit of having solar roof vent is – you won’t lose indoor heat during winter because the built-in thermostat allows the unit to run when it is required. For instance, if the roof temperature reaches less than 25 degrees, the thermostat will allow the unit to run and in the process you don’t lose any heat during winters or cooler months. While whirlybirds lack this feature due to which you lose heat in winter.

Therefore, we can say that solar roof vent performs the same functions as whirlybirds but more efficiently and effectively. You will need one solar roof vent for every 20 whirlybirds that allows you to save money in installation costs as well.

Final Verdict…….

Hence, we can conclude that solar roof ventilation systems are designed with energy efficiency in mind. You may be paying more money to install a solar roof ventilation system but believe you me – you won’t regret your decision of investing in solar roof ventilation, because you will get that money back with great ventilation all year round as well as by getting a huge reduction in your electricity bills. So, it is recommended to install solar roof vents. And for optimal performance and great ventilation, we recommend installing only SolarKing solar
