How To Pick The Best Natural Light Solar Attic Exhaust Fan?
Natural Light manufactures numerous variations of solar attic fans, but there are two main types of solar powered attic fans --- the roof mounted and the gable mounted.
Let's go over the first main type...
#1. Roof Mounted Solar Attic Fans
Roof mounted solar attic fans are the main type of solar attic fan. These attic exhaust fans are installed directly on the roof, usually on sloped roofs but sometimes flat roofs as well. Here is my install guide for solar attic fans.
The solar panel will be fixed to the main housing of the exhaust fan. Sometimes the solar panel is actually built into the housing, and these fans are called low profile solar attic exhaust fans because they are smaller and sleeker.
There are also adjustable solar attic fans which means that you can actually tilt the solar panel usually up to 45-degrees. With these attic fans, you can tilt the panel directly towards the sun to maximize the amount of solar energy you get.
The simplest attic fan has a solar panel that is not adjustable, but just fixed on top of the attic fan.

Pros And Cons
The biggest benefit of the roof mounted solar attic fans is that you only have to install one major component.
The solar panel is a fixed part of the attic fan housing, so after you install the attic fan, you are basically done with the installation.
Probably the biggest downside to these attic fans is that if you mess up the install, you are creating a leak risk. In addition, you also have less flexibility in where you want to place the solar panel as compared to the gable mounted fans.
#2. Gable Mounted Solar Attic Vent Fans
The second main type is called a gable mounted attic fan because it is installed vertically on the gable vent.
The gable vent is usually a rectangular shaped attic vent on the vertical sides of a home (the gable ends). The idea is that if you put an attic fan on one gable vent, it pulls in outside air from the second gable vent creating a ventilation pathway to remove heat and moisture.
With the gable mounted exhaust fan, the solar panel is installed remotely on your roof in a location of your choice at a distance of about 15 feet.
The solar panel is connected to the exhaust fan by an electrical cable. The suns photons hit the solar panel, and this electrical energy is sent to the exhaust fan to push out stagnant attic air.
The panel can be installed on sloped, flat, or even tiled (clay or slate) roofs.
Pros And Cons
In my view, the main benefits of the gable mounted solar attic exhaust fan is the flexibility of where to place the solar panel.
The biggest downside is that you have two installations, the exhaust fan and the solar panel.
How Do You Inspect Attic Fans?
#1. Will It Turn On?
Locate the thermostat (small metal box) usually mounted on a rafter or truss next to the fan in the attic. Turn the temperature knob so it is below the current attic temperature. You can also use a heat gun, hair dryer, or lamp to heat up the thermostat if the attic is cold.
#2. Turn The Blades
If the attic fan doesn't turn on, try turning the fan blades. If the blades won't turn, you may have a seized motor.
#3. Operation Quality
If the the attic fan turns on, are their any weird noises? Does it run smoothly? Can you feel air flow or is it very weak? The fan screen or louvers should not be blocked with debris impeding air flow.
#4. Water Stains
A common problem with attic fans are leaks. Are there any signs of water leaks around the fan on the roof sheathing?
