Here is a side-by-side comparison between the Remington Solar attic fan and another major brand fan (also found at HomeDepot.com). My technician was asked to view a customer attic who already had another brand fan on the left. He had our Remington Solar SF30-BLK (30 watt fan) installed and wanted to know why the Remington Solar was moving much more air. Panels were each facing the sun in exactly the same position.
