Discover Australia’s most effective method of quietly cooling your home, for free!

Solar roof ventilator on tile roof

Solar Ventilators quietly remove the heat from your roof or ceiling space, all day, every day, starting from first light.   This completely eliminates heat build-up, and stops heat radiating down into the house from the ceiling.   This makes the rooms feel cooler.

Secondly, if a ceiling vent is installed, the solar ventilator can draw the hottest air out of the room below, lowering the temperature in the room, and providing more comfort. This can save you a bundle in air conditioning cost, with reduced running time.

  • Removes heat from your home, garage, office, factory, warehouse or loft.
  • Effective solution for any built-up heat problems.
  • Powered by the sun, so cools the building during the time it is heating up.
  • The brighter the sunlight, the better it works.
  • Costs nothing at all to run.
  • Quietly removes heat without motor noise, or rattles.
  • Thermostatically controlled, to retain the winter warmth.
  • No noises or disturbances from the roof on windy nights.

How does a solar ventilator work?

  • Expels heat and ventilates the roof space, without power bills or carbon emissions.
  • Draws cooler replacement air from outside, or from the ceiling of rooms inside the house.

Solar ventilator cooling the living space, as well as the roof space.

  • Solar Powered  – Increases comfort, without any running cost – Save hundreds of dollars in energy costs
  • Able to reduce conventional Air Conditioning costs, and live in a fresher air environment.

If you use a roof-mounted ducted air conditioning system, a solar ventilator can dramatically increase the efficiency of that system, by cooling the roof space, and the air conditioner won’t work so hard.

Comparison of solar ventilators with wind ventilators

  • Solar Ventilators extract more than 10 times the amount of hot air than a wind-driven Whirlybird.
  • The smallest Solar ventilator can remove 10-15 times more hot air than a standard whirlybird, and the larger models remove up to 40% more air than that.
  • The difference in the cooling effect is remarkable.   Ask anyone who has made the change.  The solar ventilator runs hardest when the sun is out, regardless of whether there is any breeze or not.
  • Solar ventilators don’t make noise and cause drafts during windy nights.
  • Solar ventilators extract the hot air fast, exactly when the heat needs extracting – that is, when the sun is shining!   Because of this, they run all day, and the roof space never gets to heat up.

Roof mounted with remote solar panel.

Sometimes it is not practical to install the solar roof ventilator where it will get full sunlight all day.   In this case you can buy a solar roof ventilator with a remote solar panel, that you can install up to 5m away.   This overcomes local shading problems, or can help when you want a lower profile, so that it is not seen.

Gable-mounted solar ventilators

Large Wall or Gable mounted – remote solar panel.

When the solar ventilator is not wanted on the roof, the Gable Mount solar ventilator may be the answer.   Installation is a simple.   Cut a hole in the wall, fit the solar ventilator fan, thermostat, and its louvred safety cover, and install the remote solar panel on a nearby roof or wall.   That’s all.   Set up and ready to go!

Bushfire safety

  • Roof mounted models can be supplied with smaller grade mesh (1.5 mm openings) to comply with Bush Fire Standards.
  • Air flow is reduced by around 30%, so go up a size to get the equivalent air flow effect.

Adjustable Thermostat

  • Using the thermostat, you can control exactly when the Solar Heat Extractor will operate – only when the temperature exceeds your preset limit.
  • This means that once your set temperature is exceeded during summer, all hot air is extracted from the roof, but during winter the thermostat can be set to retain the heat, and help keep the house warm


Metal Eave Vents

Use Eave Vents to assist the direction of the air flow inside the roof space, and determine where the cooler replacement air will be coming from.  Encourage the cool air to pass over the most important parts of the house that you want to keep cool, by fitting the Eave Vents nearest to there.

Bushfire rated eave vent

Bushfire rated eave vent

Eave vents are made from galvanized steel with 1.9mm holes, to comply with Australian Standards.

We recommend installing Eave Vents when installing a solar ventilator to ensure sufficient air flow through the roof cavity.   A minimum of four eave vents should be used for each installation, one vent on each side of the house, to encourage even air flow into the roof cavity.

If the house has no eaves then an alternative needs to be found. You can use tile vents, or cowls near the corners of the houses. Remember, air behaves like people – it takes the path of least resistance – meaning that the Solar Ventilator will draw the most air from the biggest or nearest vents.  Another alternative may be to use a gable vent (if the house has a gable) as a fresh air inlet.

Alternatively, ceiling vents draw the replacement roof air from inside the house, and can also be used – and are especially effective for, double story houses – you can install a ceiling vent in the top floor ceiling.   Or if the house has a garage you can install a ceiling vent  inside the garage to improve air flow, and to cool the garage.

Gable vents are available as a vented cover for the Gable Mount Solar Whiz.  If you are installing a Gable Mount solar ventilator, you should also install the optional weather proof cover over the fan.   You will still need to install eave vents, ceiling vents, or a gable vent at the opposite gable to allow good airflow in the roof cavity.   The Gable Mount vents are paintable, so the customer may any color they like.


Adjustable Ceiling Vents

Drawing the air directly from the ceiling of rooms within a house or building, can assist in cooling the rooms, as well as cooling the roof space above.   Ceiling vents are closeable, so that when the building is being heated, they may be closed to prevent loss of heat into the ceiling space.

Adjustable ceiling vents 150mm - 300mm

Adjustable ceiling vents 150mm – 300mm

The most common use of these ceiling vents is to remove the hottest air directly from uncomfortably hot rooms, or upstairs areas of larger houses.

Height (open)97 mm114 mm140 mm180 mm


Ceiling vents can also used to reduce humidity, damp, mould or mildew problems within houses.  A ceiling vent installed in the top of a cupboard, or walk-in robe, or room that is badly affected by poor air circulation, will change the room entirely.   In bad cases, a ceiling vent may need to be installed in more than one room of the house, to provide good fresh air circulation, and remove all the damp or stale air.   Installing ceiling vents can also be in addition to installing eave vents.   When installing ceiling vents, it is recommended to use a larger model solar ventilator to allow for the extra space being ventilated, as the air may be drawn from both the roof space/eave vents and from the interior of the house.

Night Operation

Now you can operate your solar ventilator until late, long after the sun has gone down.

The Mains power Night Operation Pack cuts in after the sun has gone down, and runs the solar ventilator from the mains all night, until the sun comes up again.  Ideal for stuffy or dusty environments that you want to clear overnight, to be nice and fresh in the morning.

This works completely automatically, and will operate the fan at any time, based only on the thermostat setting.

Battery back-up for Night Operation

Introducing the Solar-powered Battery UPS Pack.   Comprises solar whiz ventilation fan SW2100RAF, with 200w solar panel, mounting frame,  regulator, maintenance-free battery pack and thermostat.   Solar ventilation fan can be located on any convenient roof, as the solar panel is mounted separately, on a nearby, north-facing roof.  Typically, the batteries are located on a platform inside the roof, somewhere they are not subjected to excessive heat.


Various battery back-up solutions available

Sizing Hint

Allow roughly 5 air changes per hour in the average roof space – this will normally be sufficient to keep the roof space temperature close to the outside ambient temperature.

In practice, we recommend using the most powerful model to extract the heat the fastest, and control it with a thermostat, so you determine when it runs.
