What Is a Solar Attic Fan and Its Importance?

A solar attic fan is a fan that uses solar power to remove hot air from your attic and pull in fresh, outdoor air. It features a vent-style construction and attaches to your roof. This fan is highly energy-efficient and sustainable.

A natural light solar attic fan is essential for homeowners looking to maintain the temperature in their attic and keep their HVAC system in good condition. By reducing the attic temperature, your HVAC system doesn’t have to work as hard to cool that area of the home. You’ll save money on energy bills and prevent premature breakdowns.

How Do Solar Attic Fans Work?

Before learning how to install a solar attic fan, it’s crucial to understand how they work. These fans have solar panels on the exterior that collect sunlight and install directly into your roof and attic. When the sun hits the roof and solar panels, the attic fan activates to cool the attic.

Solar attic fans are a green solution for cooling your attic space. Because they convert solar energy to mechanical energy, you significantly decrease your environmental footprint and don’t have to use your traditional HVAC system as much to maintain a comfortable indoor temperature.

Tools Required for Solar Attic Fan Installation

Professionals and homeowners can install solar attic fans due to the streamlined process. An attic solar fan installation requires many heavy-duty tools. You’ll need the following:

  • Reciprocating Saw
  • Drill
  • Screws
  • Roof Caulk or Sealant
  • Hammer
  • Nails
  • Stud Finder
  • Tape Measure
  • Pencil or Marker
  • A Large Piece of Cardboard
  • Solar Attic Fan

Solar Attic Fan Installation Process

The process for how to install a solar attic fan is as follows:

  • Choose the installation area, which should be no more than 24 inches from the roof’s ridge. Use a stud finder or tape measure to find the center point between the rafters.
  • Put a screw or nail at this center point. Put the solar attic fan on a large piece of cardboard and trace it around the base of the unit. Center the middle of the marked circle with the screw or nail on the roof and transfer the pattern from the cardboard to the roof tiles.
  • Screw a hole for the reciprocating saw and use the saw to cut on the marked line. Avoid cutting too deeply so as not to pierce your attic’s ceiling. Remove the pattern from the roof and lift up the surrounding shingles with a prybar to allow the fan’s base to fit.
  • Cut remaining roof sheathing and felt to remove leftover nails. Put a notch into the roofing paper large enough for the fan to fit.
  • Install the fan’s base under the roofing felt to check for the right fit. Apply roofing sealant to the bottom of the fan’s base and near the outer edge to prevent water from getting inside if it fits correctly.
  • Install the solar attic fan below the roofing tiles but between roofing paper and sheathing. Check that the fan is level with the roof. Screw around the sides of the flashing and caulk around the unit, on the screws, and between the fan and shingles to keep moisture out.
