Ensure There Are No Leaks Or Cracks In The Attic
Before solar fan installation, make sure the attic is correctly sealed off from the living space. Also, ensure that there are no leaks from outside into the attic.
The presence of leaks from the living space into the attic means the solar attic fans will draw cool air from your house. Consequently, your air conditioner will do more work to keep the house cool, and your energy bills may skyrocket.
On the other hand, if there are leaks from the outside into the attic, more heat will seep in. If this happens, you will need extra fans to sufficiently cool the attic. So, before you go installing the fans, ensure the attic is airtight from the living space and the outdoors.
Should I Hire A Professional Attic Fan Installer
Homeowners with the right experience, skills, tools, and time to do the job can opt for a DIY passive attic fan installation. However, we strongly advise shelling out on professional labor costs to ensure the installation is done correctly and safely.
There is no need to put yourself at risk of danger when a professional can do it for you flawlessly. Installing an attic fan is not a beginner-friendly project. Even trained professionals take some time to set up these fans right where they belong.
Should you plan to install an electric-powered fan, you will be required to consult an electrician for proper electrical installation and wiring. It is something you will need to consider an investment as it guarantees the safety of all the occupants in your home.
Is A Solar Attic Fan Worth The Cost
Q: Tim, can you cut through the fog of confusion about solar attic fans? Do they really work, or are they mostly hype? What does it take to really cool an attic space? My husband really thinks its a great idea to buy a solar attic fan, but I dont want to waste the money if it does little or nothing. — Bridgett W., Tampa, Fla.
A: There are talented and clever salespeople and marketing managers who can cast a spell upon you about new or newer products. Any product that has to do with solar or is touted as environmentally friendly breaks down the purchase barrier with little effort. After all, who doesnt want free energy, and who wants to be an environment hater?
I remember when the solar attic fan craze was hotter than the surface of my roof at noon on a summer’s day. Manufacturers sent me fans to test, and test I did! The results were just as I expected. The solar attic fans all moved less than 1,000 cubic feet of air per minute and they did nothing to lower the temperature inside my own attic.
The infrared rays from the sun are powerful. They can elevate your roof temperature above 160 F. I’m quite sure in certain situations I could get a reading higher than 180 F using my thermal imaging camera.
This heat is transferred to the roof sheathing and then to the roof framing members. In essence, your entire roof structure starts emitting low-level infrared heat just like the embers in a campfire.

Solar Powered Attic Fans
One common advantage about using the solar powered attic fans is the saving of electric bills. A small solar panel which can supply 10 to 20 watts is installed in the device in order to power the DC motor in the presence of sunlight. Since it is powered by sunlight, the fan runs at a faster rate when we experience more heat from the sun.
That is why the solar powered fan can function very efficiently to cool down the attic temperature during very hot days. And using one will reduce your attic fan cost.
Unlike the conventional types of fans which re powered by the main in your home, you do not have to bother about the wiring when installing your new attic fans. Without drawing the electricity from your home, you save on the monthly electric bills which you should be paying if you were to use the traditional kinds. However, you should also take note that the sun powered types can be a little more costly than the conventional fans.
When comes to installing the solar powered fans, you should know how attic fan installation to get the maximum benefits from the attic exhaust fan. Since you need the sunlight to power the fan, the position on the roof should be significant because you want the solar panel to expose to as much sunlight as possible. If the place you want to position the fan cannot capture as much sunlight as another position, you would have to separate the attic fan and solar panel so that you could get the maximum benefits.
Attic Fan Pros And Cons
All attic fans have their pros and cons. The biggest pro to any attic fan is that it can rapidly cool the attic, so your homes HVAC system does not work so hard, and your energy costs plummet, especially during warm weather. Proper ventilation from a fan keeps your roof in shape by removing moisture from the space so the roof does not rot, and the shingles do not prematurely age by shrinking, curling, or splitting. All attic fans can stop unwanted mold growth in the space. In some cases, the attic fan might not be sufficient ventilation for the space. Attic fans require maintenance, and some units are noisy. Some types require power to function, which would cause an increase in your monthly energy bill.

I Had Two Attic Breeze Fans Installed Last Summer By Your Dealer Here In The Bay Area I Was Very Impressed With The Reduction In My Electricity Bills However This Year The Fans Do Not Appear To Be Running Even Though It Is 70f Outside So I’m Wondering If They Are Operating Properly
Based on our warranty records, we see that your solar attic fans have our thermal switch control option included. Please note that this control option is a mechanical thermal switch which operates in a nominal range of 65°-75°F. This basically means that the switch has a temperature range where it can either open or close. Unlike a “thermostat” that you may use in your home with a defined temperature setting, a thermal switch has a much more course range of operation. So no worries, your fans will start working as soon as it gets a little hotter outside.
Solar Powered Attic Ventilation Fans
Yu and Moore have done research on the performance of the SPAVFs.
This experiment was done in a ranch-style house in Boone, North Carolina in the USA. The attic was around 1440 square feet of area. In this experiment, two situations were considered mainly.
In the research experiment, they have built a solar-powered attic ventilation fan with the following specifications.
- Power: 30W
- Maximum airflow: 1550 cubic feet per minute
- Solar panel capacity: 30W
- Fan blade: 12 inches
- Base flashing: 24-inch x 24-inch
In this experiment, under similar conditions, they have taken the solar irradiance readings, ambient temperature, and attic temperature readings for the given two situations above.
It was shown in the results that the attic temperature reduced from 3.90C to 140C after the introduction of SPAVF. Therefore, it is crystal clear that solar-powered attic ventilation fans also have the same effect on the attic temperature as the normal grid-tied attic fans.
Now we know that the effect of SPAVF and the grid-tied attic fan on the attic temperature is the same, lets see why SPAVF is a step ahead of the grid-tied attic fan.
The main difference between the grid-tied attic fans and SPAVFs is that the SPAVF is not connected to the grid. It does not use power from the mains to power the fan motor. Instead, it uses electrical energy produced by solar panels connected to it.

Additional Environmental Benefits Of Using Solar Energy Include The Following:
Reduced risk: Extracting coal, oil and natural gas from the earth and transporting these fossil fuels have environmental risks associated with them that generating solar power simply doesnt. When oil is being transported, for instance, there is always the chance a spill might occur which may have devastating effects on the environment. After an oil spill involving the vessel, Exxon Valdes, it took sea otters 25 years to recover to their pre-spill levels, for example.Reduced dependency: As alternative energy sources such as solar power are used more often by private consumers and businesses, the nations dependency on fossil fuels will drop. Currently, only about one percent of electricity is derived from solar power, even though the sunlight that hits the earth every day is more than 2,500 times the amount of energy used in the United States daily.Reduced depletion: As the nations dependency on oil, coal and natural gas decreases, the need to harvest these resources from the earth will also drop. This will slow the depletion of the countrys finite fossil fuel supplies.
