Solar Attic Fans and Skylight Tubes from U.S. Sunlight Corp Solar Attic Fans

I have installed the Solar Controller with NO house power connected with the Solar Powered Attic Fan but the fan is running very slow, even when the sun is out?

With NO house power connection, the only power source is solar.  There are a few ways to optimize solar capture, which directly affects how fast the fan runs:

  1. Make sure leaves, trees or other objects do not shade the solar panel
  2. Tilt and Rotate the Solar Panel or Fan Shroud to capture the maximum sunlight.  The best location is to have the panel faces south
  3. Ensure all leads are securely connected
  4. Check to make sure all wires are connected properly with red-to-red and black-to-black.
  5. If problem persists, please call U.S. Sunlight Corporation
