Solar Powered Attic Fans

The not-often thought about Green Solution...

Too often, attic ventilation is overlooked, not to mention ignored as a place for energy savings. That’s where attic ventilation solutions make sense. Consider this: air trapped in your attic can easily reach 150˚ or more. Left untreated, that heat finds its way into your home, increasing the load on your air conditioner. With an attic fan, you could lower your attic temperature up to 60 degrees F. That’s why attic ventilation is critical to making any home more comfortable while lowering energy costs. Air-conditioners can run less and won’t have to work as hard. Humid, stagnant air can be removed, drawing fresh dry air across the surfaces. Your attic can be drier and cooler – the perfect tools to help fight potential moisture damage.

And now, we offer you Environmentally friendly solutions to your attic ventilation needs. Solar Powered Attic Fans(SPAF) operate without fuel, waste or pollution. And because they are a totally solar-powered solution, they can count as points towards Green building.

How does a Solar PAF compare to a Standard PAF in cost?
Would you be surprised to learn that a SPAF is actually less expensive than a PAF? If you only look at the upfront investment, you miss the greater picture; within 1 year an $800 SPAF will cost the SAME as a standard PAF! And within 5 years, a PAF actually costs more than DOUBLE.

Learn how to get 30% of the product cost and labor for a new solar powered attic ventilator.Solar products qualify for a federal tax credit of 30% covering the cost of the product AND labor. After the 30% tax credit is figured in, at the end of year one, the Solar powered attic fan costs the same as a powered version. Because a powered version will continue to use electricity, after five years, the powered version can cost more than double that of the solar version. Most SPAFs have either 10-watt, 12-watt, or 20-watt output. SPAFs with 10-watt performance ventilate up to 1000 square feet of attic space, but most residential attics are larger and this means you will need to install multiple units. All SPAFs that have 20-watt output, ventilates up to 1600 sq.ft.- the average size of most residential attics. Better performance and superior features mean it takes only ONE SPAF to do the job of TWO lower watt models. Although they may cost less, after you add together the purchase price of buying several units, the additional installation time, not to mention additional penetrations in your roof, the SPAF actually can cost LESS while delivering superior performance. Once you know the facts you’ll see why a SPAF is a better choice.

The Difference:

  • SPAF’s use specially designed 20 watt solar panels with tempered glass that won’t delaminate as so many other models can even when hit with golf-ball size hail! Because they are so sensitive, they will work from dawn to dusk and there is not need to angle the panel towards the sun creating an unattractive roof line. Many models suggest doing this for best performance, this is only necessary if the panel cannot efficiently capture the sun’s energy.
  • SPAF’s use high-end DC motors with replaceable brushes for long life. Many SPAFs on the market use brushless motors to keep costs down.
    • Variable voltage motor automatically adjusts the fan speed based on the amount of available sun light.
    • Sealed ball-bearings provide increased protection against motor wear.
    • Zinc plated, steel motor housing provides protection against corrosion.
    • Dynamically balanced motor virtually eliminates harmonic noise and damaging vibration.
    • Low 7-1/2” profile integrates well with shingles.
    • Hurricane rated to 140 mph.
