Installation of Aura Solar Bi-Fan at Hi-rise Apartments

http://www.roofvents.com/solar-attic-... - We replaced an old vent fan with a new Aura Bi-fan and measured the difference in amperage (energy consumption). The new solar fan used 6% the amperage of the old fan even without sun; with sun, the amperage was approx. 1% of the old one. This demonstrates the huge energy savings to be realized by replacing roof fans with our solar bi-fan, which operates 24/7 using the solar panel during daylight hours and a high efficiency A/C fan during the off hours. Westage Towers has already replaced 60 of their fans without any problems. http://youtu.be/mx4bz_qShCA
