Solar Roof Vents: Why and which one?
A well-ventilated roof stays cooler on a hot summer day 1 resulting in more comfortable living spaces and cheaper cost of air conditioning. Roof vents with a solar-powered fan have been touted as more effective than passive or wind-powered vents like Whirlybirds. Although these can be bought from Australian suppliers, there seems to be little awareness that the sometimes the same product can be bought directly from the Chinese manufacturer.
