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.
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 3 year replacement 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.
HOW MANY DO I NEED FOR MY HOME?
How Many SolarKing Fans Does Your Roof Need?
Each SolarKing fan moves 2,100m³ of air per hour and automatically shuts off once the roof cavity drops below 25°C — running only when it's actually needed.
For roof spaces over 200m², we recommend installing more than one unit. Multiple fans share the workload, reaching the 25°C cut-off faster — meaning less run time per unit, less wear, quieter operation, and a cooler roof overall.
| Home size |
Approx. roof space |
Fans recommended |
| Small 2–3 bedroom home |
150–180m² |
1 x SolarKing V4 |
| Larger 3–4 bedroom home |
200–250m² |
2 x SolarKing V4 |
| Large family home / multi-level |
250m²+ |
2–3 x SolarKing V4 |
Not sure which tier you fall into? As a rule of thumb — if your roof is more than 200m², one fan will be working overtime. Adding a second unit shares the load, cools your roof faster, and reduces wear on each fan.
FAQ:
Q: How do I know how many solar roof fans I need?
A: As a general guide, one SolarKing V4 comfortably services roof spaces up to 200m². Homes larger than this, or with multi-gable or split-level roofs, benefit from two or more units for even airflow.
Q: Does the SolarKing fan run all day?
A: No — it automatically cuts off once the roof cavity temperature drops below 25°C, so it only runs when cooling is actually needed.
Q: Will multiple fans reduce noise and wear?
A: Yes. When fans share the workload across a larger roof, each unit reaches cut-off temperature faster, meaning less run time, less wear, and quieter overall operation.
