Our best-selling solar attic: Now lighter and more efficient than ever

The iSolar Solutions 20WSPF-FLEX solar attic fan.

One of iSolar Solutions’ best-selling solar attic fan has transformed into a new and better version: the 20W106-FLEX. This new fan — now lighter, more efficient — offers homeowners more flexible installation options than ever before.

What’s changed?

The upgraded fan carries on the older 19W-MOD’s stellar reputation for keeping mold, mildew and rot out of attics with efficient year-round ventilation. The 20W106-FLEX, however, now comes with a much lengthier 39-inch cable that is 33% longer than that of its predecessor. 

The longer cable gives homeowners significantly more installation options. This includes situations when the solar panel and fan must be installed far apart. This also covers situation when multiple fans must be chained together to maximize sunlight on a property. This comes in especially handy when the architectural features of a home require creative, custom installation solutions

For more challenging scenarios with tight spaces, a special crawl space package is available. This version works best to buildings like sheds or cottages that don’t have basements. It uses a special anti-gust hood to mount the fan in a small hole cut into the side of a structure. 

Though the maximum ventilation capacity of the 20W106-FLEX remains unchanged from its predecessor, our newly upgraded best-selling solar attic fan has a much more powerful 4,000 RPM motor. This allows it to reach and maintain the maximum airflow rate of 400 CFM (cubic feet per minute) more reliably. 

Now weighing 30% less, the 20W106-FLEX also literally takes a load off the backs of contractors and roofers. Though the 20W106-FLEX uses a slightly smaller solar panel, it still packs the same punch by replacing traditional polycrystalline solar cells with monocrystalline ones. Compared to polycrystalline cells, monocrystalline cells provide more efficient results at harnessing the sun’s rays. 

What remains the same?

Despite these upgrades, many of the features that made the 19W-MOD our best-selling solar attic fan will stay. The new fan keeps its predecessor’s compact size of 6.7” x 6” x 2”, allowing for easy installation into existing roof vents in under 15 minutes. 

Like the 19W-MOD, the 20W106-FLEX can pair with a CSA-approved SNOWVENTCO Roofers Vent Cover. This cover uses micropore technology to keep over 99% of debris, weather elements and small animals out.

And as with all of iSolar Solutions’ products, the 20W106-FLEX comes with a 20-year limited manufacturer’s warranty.
