More than likely, your fan is not running due to a simple loose wire (from shipping or installation) or a faulty thermostat, motor, or 110V adapter. Diagnosis and Fixes: Low Sunlight: This is the most likely cause. On a cloudy or hazy day, the solar panel is generating less power, causing the fan to run at a slower speed. Quick Fix:. . The Remington Solar attic fans are actually very simple mechanical/electrical devices. Don't know wattage (is there a way to read wattage/amperage with no load?) - A 12V 3A SLA battery came with the package, I've since tried a 12V 7A with the same (lack of) results. People like to let the sun and their flat, heat-absorbing roof do a little cooling for them.
