Roof Solar Exhaust Fan
Exhaust fans are used in solar energy systems to remove hot air from the solar panels. The same principle that operates a ceiling exhaust fan also operates an exhaust fan for a solar energy system. An exhaust fan removes hot air from a room, so the hotter the outside air, the faster an exhaust fan will cool the room down. The same is true for your solar energy system. As hot air rises it carries moisture with it. A wetter atmosphere is what leads to fog and cloud formation. If you have ever seen foggy skies after a rain, that’s the result of water being pulled into the atmosphere by its moisture content. The same process happens when there is excess heat in your home or solar system. At night, when artificial lights keep most people inside and away from their windows; this excess heat can lead to condensation on cold surfaces like your uncoated window panes causing moisture to build up on them overnight creating dew or frost in the morning. If you leave your window open during the day with no breeze blowing through it, this can cause moist air coming into contact with surfaces like wood panelling leading to condensation forming on them at night trapping moisture inside your home like a sponge again creating dew or frost in the morning again until warm enough to evaporate off again later in the day.
What is an exhaust fan?
An exhaust fan is a piece of equipment that pulls hot air out of a building or room. The same principle that operates a ceiling exhaust fan also operates an exhaust fan for a solar energy system. An exhaust fan removes hot air from a room, so the hotter the outside air, the faster an exhaust fan will cool the room down.

How does an exhaust fan work?
An exhaust fan works by pulling hot moist air from within your home and pushing it outside. This is not a difficult concept to understand. If you have an exhaust fan in your home that pushes the hot air out of the window, this is how it works.
To cool down a solar system you need to remove the moisture from the hot air or vaporize (evaporate) it so that it can be pushed outside. You need to do this while still maintaining high efficiency of your photovoltaic panels and pressure on your solar panels without any damage to them.
Types of solar exhaust fans
The most common type of solar exhaust fan is the axial flow fan which is also referred to as a box or squirrel-cage fan. This type of exhaust fan has blades that spin in opposite directions, so the air coming into contact with them moves up and out at the same time.
A centrifugal fan is another option. A centrifugal fan works by spinning in one direction only, so the air entering this type of exhaust fan will move outward but not up. The advantage to a centrifugal exhaust system is you can get more airflow with less noise because there are no blades moving in the same direction.
A third option is a counterflow design where the intake and output are facing each other.
Selecting a solar exhaust fan
A solar exhaust fan is a good choice for your solar energy system because it will help to remove moisture from the air, leading to less condensation. A solar exhaust fan typically has an electric motor that uses electricity to blow the warm moist air from the solar panels and into your home. The fan can run with either a DC current or AC current depending on what type of connection you have in your home. If you have a conventional wiring configuration in your home, you might want to choose an AC-powered fan because this type of power source is more compatible with conventional wiring configurations. On the other hand, if you are using a DC-wired system, then choosing one of these fans will be beneficial as they use less power but still perform very well.
If you are building a new system in order to replace an existing solar energy-generating unit and you don’t have any wiring yet, then it would be best to go with a DC-wired motor because they’re generally easier to install than AC motors. If however, you do already have wiring in place and are replacing old equipment then it would be best to get an AC motor so that any future upgrades could easily be implemented without having to change out the entire unit…

How to install a solar exhaust fan
The following steps describe how to install a solar exhaust fan in your roof.
1. Install the ducting for the exhaust fan intake and outtake on the roof by drilling two holes through the roof and installing screw eye connectors which are attached to aluminum tubing, one intake and one outtake.
2. Drill a hole into the roof and run a PVC pipe up through it before connecting it to the intake of the solar exhaust fan.
3. Connect an elbow adapter hose to the outlet of your solar exhaust fan that will suck air from inside your home or solar system into outside air being pulled into your home via a window located away from your solar collector panels.
4. Attach a filter on top of the PVC pipe before connecting it to your rooftop vent system so you don’t have to worry about debris falling into your home or solar system while it is sucking in air from outdoors.
Benefits of having an exhaust fan in your system
An exhaust fan can help to reduce the condensation forming on cold surfaces in your home. It will also help to drive out moisture that has condensed into the atmosphere during the day.
Exhaust fans are also a way to keep your home or solar system cooler. If you have an exhaust fan in your system, you can close your windows at night and enjoy sleeping with their closed while still enjoying the benefits of cooling down at night.
The exhaust fan will also help to prevent moisture from entering your home through a window pane where it could potentially damage something like a hardwood flooring surface. A good example would be when there is dew or frost on a window pane because water has evaporated off the window pane during the day, but then if that same amount of water comes in contact with hardwood flooring, this could cause a permanent mark that looks like a water stain on it.
There are various ways to cool down a solar energy system, but one of the most effective is by using an exhaust fan. An exhaust fan works by pulling air from your home and cooling it down before expelling it outside. This process helps keep objects inside your home from getting too moist and condensing on them. It also helps remove excess heat coming off your solar panels which can produce foggy skies or dew.
