How To Install Solar Attic Fan

Installing a solar attic fan is a job that is best left to the professionals. However, if you choose to undergo this process yourself, follow this five-step guide for installation.

Step 1: Choosing The Right Solar Attic Fan

A solar attic fan needs to fit your home’s needs. Determine how large your fan should be. Typically, 10-watt, 20-watt or 30-watt fans work best depending on how large your home is. For optimal results, the experts recommend you choose a solar panel with double the output required by the fan in use.

Step 2: Evaluate Your Attic’s Ventilation

The solar attic fan you install will take the hot air out of your attic. So, what is going to replace that hot air? Typically, most lofts have ventilation points that can be found at the eaves of your roof. You will find these located in the bottom corner of the roof. Before installing the fan, make sure the attic has the proper ventilation to take in cool air after hot air is transferred outwards. 

Step 3: Solar Attic Fans Needs To Be Grounded

Remember, your solar attic fan contains metal and it will be placed on your roof. You need to be protected against potential lightning strikes. So, how can you protect the area? The solar attic fan needs to be grounded. It should contain a grounding wire to ensure a correct connection. This step is very important in the installation process.

Step 4: Seal Attic Off From Your House

One complaint about solar attic fans is that it will draw up cool air and increase the workload on your home’s cooling system. To prevent this from occurring, you need to make sure there is an airtight barrier between the attic and home. Check the seal on your attic to ensure it is, in fact, airtight. 

Step 5: Place The Fan On The Roof

It’s very important to pick the right spot on the roof for placement of the fan. Typically, solar panels pointing south will receive the most sunlight. Place the fan on a south-facing slope of the roof, if possible. If this is not possible, it’s suggested to purchase fans with tiltable solar panels. This will give you the flexibility to point the panels southward.

Solar Attic Fan Pros

There are numerous benefits of installing solar attic fans, including: 

Run On Solar Energy

Because these fans are powered by the sun, they are considerably cheaper than most conventional fans. This means you will need no extra electricity from your home or business to power up these fans. Saving on electricity costs and helping the environment are just two reasons why solar attic fans are rising in popularity. 

Cools Down Attic Area

Another pro in the solar attic fan checklist is the fact that these will cool down your attic area, considerably. Cooling down the attic will then translate to keeping the entire home cool. The more hot air that is kept out of the attic – the more hot air that is kept out of the home in general. Solar attic fans are also known for keeping the attic space clear of any harmful dust or dirt. Keeping your home’s temperature low will help you save money on future cooling costs.

Less Expensive Than Full Ventilation Systems

Solar attic fans are typically less expensive and easier to install than full ventilation systems. These solar attic fans require less time and a much less invasive installation process.
