Solar Roof Fans

A solar roof fan is the simplest way to take the heat out of an Australian roof space before it radiates down through your ceiling. On a hot day a roof cavity can climb to 60-70°C — a solar roof ventilation fan can cut that by up to 30°C, and bring indoor temperatures down by around 6°C, easing the load on your air conditioner and cutting your cooling costs.

Every SolarKing solar roof fan runs entirely on its own solar panel — no wiring into your switchboard, no added electricity cost, and virtually no maintenance thanks to a brushless DC motor with double-shielded bearings. They install in 1-2 hours on Colorbond, Trimdek or tiled roofs, and are a straightforward upgrade for anyone replacing an old or underperforming whirlybird. For larger homes (3-4 bedrooms), we recommend two units spaced evenly along the roofline for the best airflow and heat reduction.

All SolarKing fans are backed by a 3-year fan replacement warranty, and ship free Australia-wide from our Queensland and Victoria warehouses.

Frequently Asked Questions

How many solar roof fans do I need?
One fan suits most smaller homes. For a typical 3-4 bedroom home, we recommend two units spaced roughly a third of the way along the roofline for even airflow.

Will a solar roof fan work on my roof type?
Yes — SolarKing fans install on Colorbond, Trimdek and tiled roofs using the supplied flashing and hardware.

How long does installation take?
Most installs take 1-2 hours and can be done by a competent DIYer or roof plumber — no electrician required.

Do solar roof fans run at night or on cloudy days?
Both models can be powered with an AC/DC  power supply so it can keep running after sunset or on overcast days.

What's the difference between the two models?
The standard V4 is power on / off via solar or AC/DC backup power. The V4 Wireless adds remote control (on/off, fan speed, timers, override) plus AC/DC backup power.
