Important Information for a Solar Attic Exhaust Fan Installation

For the installation of a solar attic exhaust fan, you have two options. First, you could hire a professional contractor to handle the job or two you could complete the installation yourself. Today, fans used for attic ventilation are much easier to install so the number of people taking this task on as a DIY project has increased dramatically. To be successful in getting the fan installed properly so it helps cool the hot attic, we have provided some helpful tips.

For starters, you need to measure the attic space that would need a vent system to ensure the appropriate fan is purchased. For this, determine the width of the attic floor, which would then be multiplied by the length of the floor. Then, that number would be multiplied by the number seven, giving you the amount of cubic feet per minute needed, or CFM (the amount of air pushed by the fan). Once you know this number, you want to choose a ventilation fan that exceeds it by 20.

You would also need to determine the size for the intake air louver. For this, multiply the CFM number for the fan by 144. That number would then be divided by 300. Typically, ridge or soffit vent systems exceed this amount in most homes but if you find that your house does not, it would be important to install an intake air vent for the opposite gable. The result would be with this on the exterior wall within the attic but below the roof, the attic fan would be more efficient.

The mounting flange would need to be measured on the inside. The easiest method would be to use a flexible tape measure so you end up with an accurate number. This piece of equipment is designed to encase the sleeve of the fan, the metal housing in which the fan resides, and it helps connect the gable framing. Keep in mind that some ventilation fans are designed without a sleeve. In this case, cross member bars are used to connect to the framing. For the direction of airflow, this would be stamped directly onto the sleeve or motor, pointing in the direction of the mounting flange.

Another part of the installation process for the solar attic exhaust fan is measuring the distance between the gable wall studs in the attic. Using these measurements, a 2×4 wood board would be cut and then nailed to the wall studs to create the opening for framing. You would also be required to measure the distance between top and bottom framing at the opening for the sides of the fan. All of these measures show the need for accuracy for installation of attic ventilation and when done right, the job would be completed quickly and accurately.

Using Solar Gable Attic Fans With the Appropriate Vents

Solar Gable attic fans are an environmentally-friendly option for cooling and protecting your roof and attic. These remarkable systems can literally save 30 percent on your home cooling costs. Depending on where you live, your attic can easily exceed temperatures of 160 degrees, acting as an insulator and making your air conditioning unit work overtime.

If you only have small passive vents on your roof, they are usually tragically inadequate in regards to dissipating heat. Essentially, your attic plays the role of a giant radiator as it passes heat into the living area of your home, increasing temperatures and electrical bills.

Alternatively, in the winter, the heat that is trapped up in your attic will often melt accumulated snow on your roof. Unfortunately, as the water trickles down in freezing temperatures, it often refreezes in the eaves which leads to costly, destructive ice damage. Not to mention, moisture trapped in the area will wreak havoc, promoting mildew and mold, often saturating your insulation and leading to fungal decay as well as destruction to your decking and roof frame.

What Makes a Solar Attic Exhaust Fan Different?

A solar Gable fan runs completely on solar energy rather than electricity. Sunlight is transformed into electrical power by use of a solar panel. These are often used along with Gable vents for budget-conscious, effective operation all year round.

The solar panel and vent are positioned in an appropriate location in the gable end of the attic and then they are both mounted. Despite what you may be thinking, installation is easy because there are brackets with the solar panel to allow for easy roof mounting. The solar fan and vent are connected by a simple plug and the result is free power.

The solar panel uses sunlight to work as a generator, allowing the fan to work without electricity from dawn till dusk when cooling is needed most. These systems create air movement in quantities of 800 cubic feet per minute. This will remove damaging winter moisture and uncomfortable summer heat. Additionally, the solar panel is hail, wind and impact-resistant so it can stand up to even the harshest elements.

Solar Gable attic fans are highly efficient and durable, running on a 24-volt DC motor. The shutters are typically white plastic but can easily be painted to match the exterior of your home. They are fuss-free and will open automatically when the fan is running and close back up when it is not in use.
