Installation Instructions:

    1 In attic, mark location of solar-powered vent between two roof rafters.
    2 Drive nail through center of vent location.
    3 Install roof brackets and fall-arrest system to roof.
    4 Scribe outline of vent’s flashing on roof using homemade dowel compass.
    5 Cut shingles along circular outline with a utility knife.
    6 Pull nails and remove shingles from within the circle.
    7 Use compass to scribe hole for vent onto roof sheathing.
    8 Cut hole in roof with a reciprocating saw.
    9 Remove shingles from around the vent opening.
    10 Apply continuous bead of tri-polymer roofing cement around hole.
    11 Set roof vent over hole, then screw the fan’s flashing to roof.
    12 Apply more caulking around flashing.
    13 Replace all the roof shingles around the vent fan with 1 ½-inch roofing nails.

    Minimize backpressure of exhaust gases.

  • Angled throat within the flashing that provides a venturi effect, which increases airflow.
  • This Solar Attic Fan was designed from the ground up to minimize obstructions in the flashing and  shroud.

    Maximize the exposure of the sun to the solar panel.

  • The mounting bracket that houses the solar panel that allows for angling the panel.
  • Optional remote solar panel can be installed away from the attic fan housing for applications where there is limited sunshine where the unit is installed.
  • The remote panel is installed in a sunny area, capturing maximum sunlight and achieving optimal fan performance.

    3. Minimize the ambient temperature of the solar panel because power output rapidly declines as temperature increases.

  • The entire assembly is powder coated, inside and out, in a neutral gray color ensuring that it does not act like a heat sink.
  • The solar panel mounting bracket allows for an envelope of cool air to continually circulate around the entire solar panel.

    4. Adaptable to any location, roof type, in any environment.

  • Constructed of .080 (14 gauge) aluminum, the flashing and shroud are seamless ensuring weather tight  installations.
  • Stainless steel animal protection screen.
  • Stainless steel hardware throughout.
  • Powder coated to withstand any environment.
  • Fifty year Neutral Cure silicone bonds the flashing to the roof.
  • Ease of Installation - Fully operational right
    from the box, it installs easily, no wiring, no
    electrician, no permits.

  • Adaptable - to any location, roof type, or

  • Venturi Effect - Angled throat creates venturi
    effect, increasing airflow.

  • Weather Tight - Seamless flashing and
    shroud ensure weather tight installation.

  • Environmentally Safe - We adhere to
    environmentally safe practices and procedures
    during the manufacturing process.

  • Solar Attic Fan lowers attic temperature which
    reduces the load on the HVAC System.
  • The most obvious reason for attic ventilation is
    to lower attic space temperature during the
    warmer months. Attic temperatures can
    exceed 160°F during hot summer days.
  • Proper attic ventilation can reduce those
    temperatures by up to 50°F. No matter how
    much insulation is in the attic, heat can still
    transfer into adjacent  living spaces.
  • In fact, extra insulation can actually add to
    temperature increases because heat is
    trapped in the insulation. Proper ventilation
    evacuates this excess heat build-up.
  • As the heat is exhausted, the work load of the
    air conditioning system is reduced, thereby
    saving energy and extending the life of the air
    conditioning system.
  • Extends the life of the roofing materials.
  • Though asphalt shingles are designed to take
    the abuse of the sun for many years, they are
    subjected to greater temperatures when the
    roof decking is allowed to overheat, which is
    just what happens in an under ventilated attic.
  • In the cooler months, moisture is the most
    serious concern. Even with the use of vapor
    barriers to keep moisture from entering the
    attic, there are air leaks around ceiling light
    fixtures, bathroom exhaust fans that allow  
    unwanted moisture into the attic. Moisture
    condensing on the framing members and the
    inside of the roof deck can lead to the growth
    of mold, mildew and rot in the roof deck and
    framing. A good indicator of moisture problem
    is rusty roof nails sticking through the roof
  • Asphalt shingle manufacturers warranties
    require proper attic ventilation.
  • Attic ventilation is required in cold
    environments - it evacuates the warm moist air
    that heat sources produce. Hot moist air
    lingering in the attic spaces can condense on
    the underside of the roof sheathing and rot it
    out and also causes mold to develop on the
    interior walls.
  • Cold air in the attic space will not affect the
    temperature in the adjacent living spaces if
    properly insulated.               
  • Good ventilation helps prevent ice dams,
    which begin to form when warm air in the attic
    melts the snow from beneath and creates
    runoff that  refreezes on the colder eaves.
