10 watt Solar Ventilation Fan

The Solar Ventilation Fan is an economically sensible way to move air and reduce climate control costs.  During the summer, attic temperatures can climb as high as 150^oF.  The heat causes the attic air to expand, causing downward pressure that will force heated air into the living space.  This air flow results in higher cooling costs and increased wear and tear on an air conditioning unit.  During the cold winter months, the ventilation system reduces the build-up of attic moisture.  Untreated, this moisture can result in wet insulation, cracking plaster, peeling paint, roof damage and mildew buildup.  The Solar Ventilation Fan begins operation at dawn and slows the rate of heat build-up during the day.  Traditional AC powered units do not activate until the temperature reaches an average of 104^oF, requiring the unit to operate at excessive speeds to adequately cool the space.
