Solar Attic Fans That Make Sense.

A Product of Solatube International.

The first question you must ask yourself, "is solar right for your home?" Several factors must be taken into account when considering this type of product. To achieve maximum performance from a Solar powered vent, it is important to locate the unit in the area of your roof that receives good sun exposure all day long.

1. Which direction does the roof surface face?
    Exposure of the solar panel to the sun is the most critical factor when determining if
    solar is right for you. Southwest is the best direction for excellent performance all
    year long. South offers very good performance also. West gives you the advantage
    of late day operation, which reduces the intense heat during the hottest part of the
    day. For Roof Mounted fans, very steep roofs that face south or southwest can use
    either a Low Profile or Pitched flashing.

2. Are there any obstructions that will cause shade or shadows?
Tall trees, chimney's, or your neighbors home should not be so close as to create shade or shadows in the location of the
Solar vent. Since the unit is powered by the Sun, heavy shade can cut the performance by as much as 50 percent.

3. Is your attic insulation installed to the proper "R" Value?
    If your attic insulation is less than the recommended "R" Value for your location, no amount of attic ventilation will eliminate
    the damaging conditions of intense summer-heat and winter-moisture. Insulation and ventilation, work together as a system
    to control and eliminate these conditions.

4. Gable Mounted or Roof Mounted unit?
    Determining which application is simple. If you have existing "whirlybirds" or some other
    type of roof ventilator, than replacing this unit with a new Solar powered ventilator is the
    best option. If you have no roof mounted venting units, and you have gable vents in the
    peak of your home, than a gable mounted unit will work best. Also, a roof mounted
    Solar powered vent will operate efficiently in either of these applications.
