Solar Roof Vents v Whirlybirds

Solar vents take out 5 to 10 times more air then the whirlybird. (Eco solar vent)
On the hottest days when there’s no wind! Full sun! The solar vent works 100%
On flat roofs with no heat convection (heat rising) the solar vent will suck the heat out.
Solar vents have a built in thermostat, so they turn off in winter. (keeps the Heat in)
Solar vent is better value for money. Cost more but removes more heat.
With the thermostat it uses the brushless motor less, will last twice as long (15 years)
Solar vents will save you money on air conditioning cost

The solar vent will make a little bit of noise. If you listen you could hear it?
Solar vents only have a 5 year warranty but will last 15 years
