Melbourne’s unpredictable climate throws everything at your roof. In summer, trapped heat turns your ceiling space into an oven, forcing your air conditioning to work overtime. In winter, that same space traps damp air, leading to hidden condensation and structural mould.

It is time to replace that squeaky, ineffective whirlybird with a Solar Whiz.

Designed specifically for harsh Australian conditions, Solar Whiz is a market-leading, solar-powered exhaust fan that actively pulls massive volumes of hot, stale air out of your roof cavity. It keeps your home naturally cooler in summer, dry in winter, and costs absolutely nothing to run.

As licensed roof plumbers and tilers, JSIU Roofing supplies and perfectly installs the entire Solar Whiz domestic and commercial range across Greater Melbourne.

Our Most In-Demand Solar Whiz Models:

• ⚡ Solar Whiz SW-AU-R-28 (The Mid-Range Workhorse): Perfect for the average Melbourne home (up to 180m²). This 28-watt unit moves 1,700 cubic metres of air per hour—delivering the same cooling power as 17 standard whirlybirds!
• 🏗️ Solar Whiz SW-AU-R-40 (The Heavy-Duty Performer): Built for larger homes (up to 250m²+), double-storey properties, or metal Colorbond roofs. This massive 40-watt unit extracts 2,300 cubic metres of air per hour (equivalent to 23 whirlybirds!).
• 🌊 Coastal & Bushfire Ready: We install specialized SS316 Marine-Grade Stainless Steel models for coastal Melbourne suburbs, as well as fully Bushfire-Rated units (BAL compliant) for high-risk zones.

• Night Operations Pack: Want cooling after the sun goes down? We can install the optional "Constant Current" Night Pack, allowing the fan to seamlessly run using mains power at night to flush out remaining humidity.
• Smart Thermostat & Hygrostat Control: Don't lose precious heat in winter. The adjustable thermostat ensures the fan only turns on when your roof hits your set temperature (e.g., 30°C), while the hygrostat kicks in specifically to extract damaging moisture.
• Whisper-Quiet Operation: Powered by advanced brushless DC motors and double-shielded ball bearings, Solar Whiz operates at a whisper-quiet <45 to <60 decibels.
• Zero Running Costs: 100% powered by the sun. Maximum cooling during the hottest part of the day without adding a cent to your electricity bill.
