IMPORTANT! Grants for Small Business Installing Ventilation Systems

The Victorian government has recently announced a program that provides funding for small businesses installing systems that aim to improve indoor ventilation.

The program will provide funds that match costs for projects between $1000 abd $5000. If you are a small business and looking to install a Solar Whiz system we strongly encourage you to read more about the Grants for Small Business.  

What is the Solar Whiz?

The Solar Whiz is a powerful solar roof ventilator & exhaust fan that can operate completely without mains electricity. It has superior performance and is highly adaptable and flexible. Solar Whiz has been designed specifically for Australian roofs and can be easily installed in all different climates and applications.


Keeps You Cool

Roof ventilation works by pulling the hot air that builds up in your home and/or roof space and replacing it with cooler, ambient air from outside. This reduces the overall temperature in your home and stops the transfer of heat from roof spaces into your home.

Keeps You Dry

Solar Whiz’ solar exhaust fans are also used to extract moisture and condensation from roof and under-floor areas. This is an excellent way to remove and prevent mould in your home that could be impacting air quality or even the structural soundness of the building.

Boosts Energy Efficiency

With a cooler roof space and less transfer heat, your existing air conditioner heater won’t have to work anywhere near as hard to achieve the same results. An air conditioner that runs better costs you much less and lasts you much longer!

Free to Run

Solar Whiz is a market-leading solar roof fan that can run entirely powered by the sun. That means that there are never any electricity bills associated with your solar fan.

Renovating or reflooring?
Now would be a great time consider getting proper sub-floor ventilation installed. It is much easier to achieve the desired results when there is easy access to the underfloor area.

How Does The Solar Whiz Work?

The Solar Whiz roof ventilators and exhaust fan prevents heat build-up in your roof cavity and attic space and reduces the heat load on your ceiling. This prevents heat from radiating down into your living space. This results in lower roof space temperatures as well as lower internal temperatures. Solar Whiz roof ventilation provides your family and businesses with a more comfortable indoor living and working space, whilst potentially saving you hundreds of dollars on cooling costs, if you’re using air conditioning.

Replacement air is the key to the Solar Whiz functionality, and must be available for the unit to effectively remove heat or moisture. Replacement air is most commonly accessed via eave vent or ceiling vents. Heat or moisture may also be extracted directly via ducting.

Eave Vent Roof Ventilation

Solar Whiz extracts hot air out of your roof space, and replaces it with cooler ambient air from outside.

Roof Ceiling Ventilation

Solar Whiz systems can also extract air directly out of your home interior via ceiling vents.

Ducted Roof Exhaust Fan

If you need specialized extraction, Solar Whiz can be set up with ducting.

Spring and Summer Operation

Roof temperatures can easily reach temperatures of over 60°C on a hot, sunny day. This heat can have a few effects on your home:

  • Ducting systems (like air-conditioners) have to work harder to keep cool and effectively function
  • Heat transfers from the roof space into the rooms below, making them hot and uncomfortable
  • Internal structures may even warp and deteriorate due to extreme heat

A Solar Whiz’ solar powered fan is perfect for

extracting the heat from any roof space. Which subsequently increases the efficiency of your air-conditioner whilst also keeping your house cooler in the first place!

Autumn and Winter Operation

Many people don’t realise that roof ventilation is just as important during the colder months as it is over summer. Colder, wetter weather leads to an increase in moisture and humidity in your roof space. Everyday household activities such as showering, cooking and drying clothes also contribute to higher levels of moisture. Ultimately, a damp roof-space can result in:

  • Damaged or warped internal structures
  • Mould and mildew growth that can cause or worsen health issues like asthma and dust mites

Our solar powered fans are a powerful solution for removing moist air and keeping your roof space healthy and dry.

After installing the Solar Whiz roof ventilation system, the efficiency of your existing air conditioning system will also improve. Your air conditioner won’t need to work as hard when operating and the actual running time will be reduced, as you won’t need to run the air conditioner as often.

Solar Light Whiz

Skylight Alternatives

“Thanks for getting the lights to us super fast. In regards to the actual system and the output of the LED panels—THEY ABSOLUTELY ROCK. They have exceeded my expectations, especially in low light.

“I am trying to convince everyone who takes a look at our new renovations to look into installing some. Many thanks for all your help.”

Solar Air Module

Fresh Air & Solar Heating

“The SAM system meets our needs. When the sun is shining, huge amounts of warm, dry and importantly, fresh air is pumped into the house. The effect of this is the ambient temperature in the house reaches 20°C, keeping the home warm for long periods of time. As a result we have reduced our reliance on fossil fuel heating sources between 60% to 80%, depending on the weather conditions. From our perspective the air in the house is also ‘fresher’.
“[…] We are very pleased we installed a SAM system (and the ‘Solar Whiz’) and I would recommend it as a way to offset heating expenses and meet health and environmental needs.”
