Benefits of the Solex Attic Fan

Benefits of Solar Attic Fans During the Summer

It is no secret that during any given summer day, most attic temperatures can reach temperatures well above 170 degrees. It is for this reason, most homes have soffit ventilation coupled with several small vents and gable and/or ridge vent ventilation, this is called passive or convection ventilation, the theory being simply stated, "hot air rises". Unfortunately it simply doesn’t work all the time. It also expands and radiates. When it doesn’t, it creates "heat oppression". Your roof holds heat; the air in your attic holds heat. Everything in your attic holds heat. Every morning the sun comes up and the roof of every home begins to broil, and the air in your attic begins to expand, in every direction, not just up. There is no question the vents at the ridge of your home will exhaust air, but only as it is warmed to the point of expansion. In short, the convection-ventilation process actually requires a certain amount of heat retention to begin the ventilation process! Once it’s started, the battle is already lost! Your roof will never be cooler then the heat load point required for convection.

Shrink your energy bill, save money and earn a home tax credit all at once. The Solex Attic Fan reduces heat gain! The Solex Attic Fan can vent up to 1,275 cfm of hot air during the summer. By reducing the amount of radiant heat that is conducted by the ceiling, heat gain within the interior can be dramatically reduced. Attic temperatures can reach 170° F or more in the summer. That translates to ceiling temperatures of 100° F or more. By venting heat within the attic before it is conducted by the ceiling, ceiling temperatures can be lowered by 10°-30° F. Interior room temperatures can be lowered by 5°-15° F. Lower room temperatures also increase the life of wall coverings, floor coverings, furniture and other home furnishings. Over time, lowering home maintenance expenses can save you money as well. There is also a tax credit for energy efficient homes. Remember: heat is the enemy-except when you're cold.

The Solex Attic Fan is a ventilation product that reduces utility bills and equipment maintenance. Less interior heat gain equates to a lower load on air conditioning equipment. Whenever the AC compressor is off, less electricity is used. You can save thousands of dollars in electric expenses over the life expectancy of the Solex Attic Fan. Lower AC usage equates to less wear and tear on the equipment which, in turn, lowers maintenance costs. So if lowering your energy and maintenance bills is a priority, you've come to the right place.

The Solex Attic Fan is a solar-powered product that increases the life of your roof. Heat accelerates the breakdown of roof materials. A cooler attic equates to a cooler roof which means a longer roof life. A longer roof life saves you money, time and frustration.

Benefits During Winter

In the winter months, ventilation reduces the build-up of moisture in the attic and prevents ice dams. The Solex Attic Fan ventilates the attic year-round so it prevents moisture build-up and ice dams which can result in wet insulation, mildew, decay, cracking plaster, peeling paint and roof damage.

Why the Solex Attic Fan?

"The Solex Attic Fan is powered by a 20-watt Mono crystalline photovoltaic panel. Most solar attic fans on the market use any 10-watt panel offered and attempt to do do what we do with multiple fans, it simply doesn't work that way. We discovered some 12 years ago that it's not the volume of air you can vaccuum on a whole, it's the impact the sun has on each fan, and the restrictions soffit ventilation has to offer. 10 watt fans simply can't move enough air, regardless of how many you put up there. Eventually the heat will catch up. Our fans and panels are both matched and tuned and will operate better, longer and through far more adverse conditions then any fan in the business."

During the warm summer months, all homes have something in common called "heat gain." Heat gain occurs after the radiant heat from the sun is absorbed through the roof and radiates into the attic air space. Radiant heat always moves from the source of heat to materials with less heat. Thus during the summer, radiant expands in all directions. Mass insulation such as fiberglass or cellulose does not stop radiant heat. Once radiant heat passes through the insulation, it will be conducted by the interior ceiling and walls. Once the temperature of interior surfaces heat up, your home is suffering heat gain.

Heat gain through the roof, attic and ceiling is the primary cause for warm or hot houses. Of course, air conditioning can offset the heat gain, but at what cost?

We have a Pro-ACTIVE “WHOLISTIC” solution. Our solar attic fan is on at dawn, off at dusk, operating properly at the temperature inversion times of the day. It actually begins to exchange the air of your attic before the heat of the day. Silently, all day long, at such a rate that heat-gain and loading is all but eliminated. In addition, any wet air that may have had a chance to enter the home from the night before will be drawn out before the heat of the day. Thereby breaking the compounding effects of humidity oppression, and dramatically impacting the potentials for mold and mildew. It is common to see attic temperature drops in the summer of as much as 60 degrees, and A.C. savings of as much as 30% (results will vary), and in winter months where humidity levels are highest, our operation is diminished but still essential, as it ensures a dry attic with no added heat loss in the home.
