SOLAR ATTIC FAN
COMPARISON MATRIX

What you don’t know can effect you, your home and your pocket-book.

Our objective is to provide our consumers, installers and/or partners with an accurate comparison matrix so that an educated decision can be made when it comes to making a purchase. Details and characteristics of individual products can be difficult to accurately locate. So, that’s why we have created a tool for comparing different makes and models of solar attic fans.

Just like any vehicle on the road, there are huge differences between the makes & models and, consequently, the same applies to solar attic fans.  Furthermore, even though one looks like it’s a better deal or another product is sold/offered to you because the installer has used them for many years, the devil is in the details. Please compare the ones listed below by checking the ‘check-box’s’ to the right of the product and then click the compare button.  We have listed the major brands most sold with companies behind them that can support them professionally but if you would like us to add another product to the list, please email us to review and consider adding. We welcome your feedback at [email protected] and so we can update any inaccurate information because we make every effort to keep the list up-to-date and all information is taken from publically available resources. All trademarks and brand names are the property of their respective owners.

**IMPORTANT FACTORS**  TO LOOK FOR WHEN CONSIDERING A COMPARISON MATRIX OF SOLAR ATTIC FANS:

  • Only use products with Brushless DC motor  > Here is why?
  • It is easy to install & access later, see how easy the SR1800 is to install or access.

  • Also, look for aluminum, ABS & stainless steel materials, because alternative materials rust and/or corrodes much faster.

  • Certifications passed on current models. Important to know as it could become an insurance problem later.

  • Solar panel type, Monocrystaline is the best so why settle for less.

  • Aesthetics; ‘square peg in round hole’ or does it look like a restaurant grease trap, in our opinion aesthetics is important.


Thanks for taking the time to review and understand the differences in solar attic fan (ventilation) products.  If someone tells you that active ventilation is as good as passive ventilation they are wrong.  Bottom-line, as long as you have enough external intake to support active ventilation capacity you are golden.  What should you be looking for:  Brushless motor, Easy of installation & to maintain which we address with our two piece design, solar panel type and quality of components (material used).

Another note regarding comparison to other products, many other products on the market have not been updated in several years and most have not passed the latest certifications because the law states that any changes to a product must be retested. However, you will find most tests linked on the respective companies website are several years old. So, this means the latest versions have not even been tested, which is never the case with Solar Royal products or could mean the possible product being offered has not been technically updated in many years – both scenarios in our opinion is not in your best interest.

Use following calculations so you can verify our comparison matrix yourself. You can also check with your roofer, green energy audit company, builder, or contractor to verify the following comparison matrix in relation to what you are looking to ventilate (we will have automatic calculator).

Proper ventilation is a direct result of proper installation

Sizing Balance Orientation

CFM Required for Comparison Matrix Net Air Comparison Matrix Ave-Pitch Comparison Matrix
Attic Size CFM Required Net Air
Intake (sq.in.)
Ave.Pitch
~6/8
1800 sq.ft. 1260 604 1 Fan
2100 sq.ft 1476 705 1 Fans
3500 sq.ft 2450 1176 2 Fans

There are various types of intake. The air being exhausted needs replaced by outside air drawn through unobstructed air vents. These soffits are normally found under the eaves on a home but the key is that for air to properly be exhausted the intake must be cleared, regardless of application. First, to calculate the total minimum vent intake area in square inches, divide the CFM ratings of the solar ventilation by 300 and multiply the result by 144 which will give you the Net Air Intake as recommended by hvi.org.

Calculation demonstration: 1300 ÷ 300, then × 144 = 624 net air intake required. Then the Solar Royal Attic Fan moves up-to ~78’000 cubic feet per hour. The intake must be balanced for it to do it’s job. So, ~4.2 sqft of Net Free is suggested per fan. In addition, one of the best features of a solar attic fan is the cost savings. Please note that this is only an estimate, however it gives a clear comparison of solar fans vs. electric ventilation. The figures also do not take into consideration the energy savings from keeping your attic cooler.
