It's HOT and it seems to get hotter earlier every year. The Solarking solar whirlybird roof extraction fan is simply mounted up high on the roof and extracts all of the heat from the roof space which will reduce the internal temperature of your home. For smaller homes, one will suffice. For modern 3 to 4 bedroom homes we suggest spacing 2 units a third of the way (roughly) along the roofline. Any handy person or roof plumber can install these in around 1 - 2 hours.

How It Works

The SolarKing Solar Roof Fan is strategically placed high on your roof to pull in cooler outside air, forcing it through the roof space and expelling hot, stagnant air. In summer, this solar ventilation system mimics the natural cooling effect of a two-story home, where upper levels block heat from lower ones. The adjustable solar panel ensures maximum efficiency, even on non-north-facing or flat roofs, while the DC input keeps it running after sunset with an optional power pack.

Cost Savings and Value

Priced competitively, the SolarKing Solar Roof Fan offers exceptional value. With no running costs and a potential reduction in air conditioning use, homeowners can save hundreds annually on energy bills. Compared to whirlybirds the SolarKing’s 2100 CBM/h airflow and 30°C temperature drop make it a cost-effective investment. Free shipping is included from SatPlus, adding to the savings.

Why Choose SolarKing Over Whirlybirds?

Traditional whirlybirds move just 100 CBM/h and depend on wind, making them unreliable in still conditions. The SolarKing Solar Roof Fan, with its solar-powered 2100 CBM/h capacity, delivers consistent performance whenever the sun shines—perfect for Australia’s sunny climate. Its corrosion-resistant materials suit coastal regions, and the 10-year solar panel warranty ensures long-term peace of mind.

Ideal Applications

Residential Homes: Cool single-story or multi-story homes with tile or metal roofs.

Garages and Sheds: Prevent heat buildup in workshops or storage spaces.

Final Thoughts

The SolarKing Solar Roof Fan is the ultimate solar-powered roof vent for Australians seeking a sustainable, cost-saving cooling solution. With its powerful airflow, durable build, and advanced features, it outshines competitors like whirlybirds, delivering comfort and efficiency year-round.

HOW MANY DO I NEED FOR MY HOME?

Estimate Roof Space Volume

The number of fans required depends on the volume of air in the roof space that needs to be ventilated. Roof space volume is calculated as:

Volume = Floor Area × Roof Height Most Australian homes have a pitched roof with an average height of about 1.2 to 1.5 meters at the peak, tapering to the eaves. For simplicity, I'll use an average effective height of 1.5 meters for the roof cavity.

200 m² home: Volume = 200 m² × 1.5 m = 300 cubic meters (m³)

300 m² home: Volume = 300 m² × 1.5 m = 450 cubic meters (m³)

Determine Ventilation Needs

Ventilation standards often recommend exchanging the air in a roof space 10-20 times per hour to effectively reduce heat and moisture buildup. For a conservative estimate, I’ll use 10 air changes per hour (ACH), which is suitable for general roof ventilation in hot climates like Australia.

200 m² home: Required airflow = 300 m³ × 10 ACH = 3000 m³/h

300 m² home: Required airflow = 450 m³ × 10 ACH = 4500 m³/h

Calculate Number of Fans

Each Solarking fan extracts 2100 m³/h. Dividing the required airflow by the fan’s capacity gives us the number of fans needed:

200 m² home: 3000 m³/h ÷ 2100 m³/h ≈ 1.43 fans (round up to 2 fans)

300 m² home: 4500 m³/h ÷ 2100 m³/h ≈ 2.14 fans (round up to 3 fans)

Rounding up ensures adequate ventilation.
