Solar Attic Soffit Vent Fans


30 watt solar powered soffit fan kit. Flex Mount not shown.

Small. Powerful. Versatile. Effective.

  • 30 watt monocrystalline solar panel, compact high output IP55 fans that fit inside the soffit vents, and our unique, infinitely adjustable tilt & rotate solar panel Flex Mount combine to provide fresh air supply to the attic, reducing attic heat & humidity in the lower attic, just above the living area ceiling.
  • Fans push cool outside fresh air deep into the center of the attic and ceiling area. 
  • Easy Installation with basic tools. No – 
    • Cutting or drilling holes in the roof. 
    • No leaks.
    • No need to access the roof or attic. Fans typically  installed from outside through soffit vents.
    • No roofing work or repairs.
  • Proven hurricane tough.
  • Each SPSF 430D (shown above) ventilates up to 1000 square feet of typical, non-partitioned attic with fresh air supply. 7-10 fresh air changes per hour above the ceiling, where it counts.  
  • The unique solar panel Flex Mount attaches to solid structure  (wall, chimney, truss ends, solid fascia, etc), not to the roof deck.  This allows optimum sunlight capture from any side of most buildings, and allows the solar panel to be located out of street view. 
  • Automatic on-off. 
  • Quiet    
  • Warranty
  • Tax credit eligibility
  • Output should always be directed from the soffit vent, horizontally across the attic, blowing fresh air in just above the attic  ceiling insulation. If insulation baffles are installed, ensure they allow  at least the same opening area into the main attic as the fan opening.    
  • Solar Powered Soffit Fans are not a substitute for adequate ceiling insulation, ceiling sealing, or adequate AC duct and register insulation and sealing.
