C attaching the roof ventilator to the throat. The support assembly comprising: a body having a top and a bottom; a plurality of support 
anns extending from the body for engagement with the inside surface of the throat, and a passageway running through the body from 
00 the top to the bottom. A solar panel support assembly, for supporting a solar panel, located at the top of the support assembly. A solar 
powered fan powered by a motor, each of which are located at the bottom of the support assembly. A blade support assembly provided 
onthe body rotatable relative to the body. A series of blades mounted to the blade support assembly; the series of blades adapted to spin 
under the influence of air movement from the outside atmosphere. In the roof ventilator, the electronic circuitry from the solar panel 
Travels from the solar panel through the passageway to the motor that powers the solar powered fan; and the roof ventilator is able to
