attic fan solar roof attic ventilation fan solar powered attic fans
Solar Attic Fan DemonstrationAttic fan powered by solar energy will help cool the hot trapped air by drawing in cooler outside air from from the roof attic vents and pushing it outside circulating the fresh air. In the last several decades, building codes have called for increased attic insulation and ventilation. A well ventilated attic keeps the house more comfortable in summer and guards against moist, heated air building up in winter.
The goal is to have the temperature in the attic the same as the outdoor temperature. This concept gives some people difficulty as they assume that to keep the house cozy, the attic should be as warm as the rest of the house. It is best to consider the attic space as part of the great outdoors and the sloped roof as nothing more than a big umbrella. In addition to adding an solar powered attic fan, or several as needed, you should have insulation on the floor of the attic rather than the underside of the roof. It is critical that in this process of remodeling your home that you do not block the attic vents which will cause air to be drawn from the house rather than the outside. A solar powered attic fan will help provide the proper ventilation your roof requires for a health house with one distinct advantage, they do not require any special electrical wiring.
Attic fan powered by solar energy will provide forced attic ventilation.
Regardless of how one try's, it is not possible to created a perfect air barrier in the ceiling of your home. Warmer most air will escape into the attic space creating the need for good attic ventilation which an attic fan can facilitate. At first it may seem odd to add ventilation for warmth allowing cold air to enter the attic through solar attic power fan and vents, but this combination is the key to a durable and energy-efficient home. Proper venting cools your roof extending the material life and reduces the load on your air conditioning system.
Attic venting also increases fresh air circulation which reduces vapor build up generated by everyday activities like showering and cooking. Excess moisture trapped in your attic can cause a variety of problems from rust to rot to increased bacteria and mold counts which can have a direct impact on your respiratory health! Passive vents have been a part of building codes for years but soffit vents, ridge vents and louvers rely on nature to provide sufficient air pressure and air movement. So the majority of the time your attic is stagnant and continues to build up heat and moisture.
Solar powered attic fans will ensure a natural flow of outdoor air to ventilate the attic which helps keep it cold, reducing the potential for ice damming in the winter. Ice damming is when snow melts off a roof from an attic that is too warm and then re-freezes at the gutters, causing an ice dam that can damage the roof. Attic ventilation with solar powered attic fan (fans) are used widely in cold climates to evacuate the warm, moist air that escapes from the living space below. If this air lingers, it can condense on the underside of the roof sheathing and rot it. solar powered attic fan will ensure proper circulation keeping attics cold in winter not allow warm most air to condensate under the roof from below.
In the summer, a solar powered attic fan with create air flow in a well-vented attic moves super-heated air out of the attic, protecting roof shingles and removing moisture. When you couple solar powered attic fans with good home insulation when you remodel your house, the combination will resist heat transfer into the house.
Solar-powered attic fans require a hole to be cut in the roof, possibly two if you purchase one that has the remote-panel location feature. If you do not know how to properly flash these fan housings into the roof shingles, then you should hire a qualified roofer. It is not hard to do the work, but there are very important steps that must be followed to have a leak-proof installation.
When installed properly on a roof with standard asphalt shingles, solar-powered attic fan do not require caulk, roofing cement or any other product to prevent leaks. A great roofer will cut the shingles and lace the fan housing into the shingles so that rain will stay outdoors where it belongs.
If your attic space is over 1,800 square feet, you will need multiple solar attic fans to move 8,000 CFM. You need that amount of air, if not more, to get any sort of cooling benefit from the fans.
The SunRise ™ solar powered attic fan is a unique, solar-powered vent fan that pulls the heat right out of your attic. It's so effective it can lower attic temperatures by as much as 50° with possible savings up to 30% in cooling costs along with extending the life of roof shingles. During the winter the constant circulation of air will prevent ice damns and help deter mold and mildew. Attic venting with solar powered attic fan or multiple attic fans is an important aspect in maintaining the functions in your home.
The SunRise solar panel employs the latest state-of-the-art circuitry capturing sunlight and turning it into electricity to power your solar attic fan even on overcast days. Totally weatherproof, the SunRise solar attic fan panels are designed for optimum efficiency and are hail and extreme weather resistant. The cover and base of the SunRise solar attic fan is built with a molded UV-stabilized ABS plastic to prevent damage from sunlight. The top has a hinged appearance, helping units blend in with roofs while providing additional stability & strength. The SunRise solar attic fan blades are specially designed 5-blade, 12” aluminum solar attic fan that is pitched for maximum air flow. It operates “whisper quiet” with no harmonic noise.
SunRise solar attic fan has a stainless steel screen that keeps animals out while allowing maximum air flow. The mounting hardware for the solar powered attic fan has stainless steel motor brackets & vertical standoffs that provide a flexible & adjustable frame for easy removal or replacement.
Sunrise solar attic fan is also available in gable-mount, and curb-mount for tile, shake and flat roofs. If you are going to go with a solar powered attic fan we urge you to by several solar-powered attic fans. With the SunRise attic fan you have many options such as locating the fan on the North side of the roof and the solar panel on the South side of the roof ridge away from the actual fan. This is a neat attic fan feature.
When you are installing your solar attic fan, be sure to locate the solar panel on the roof where they will not be shaded by trees, and where they will get direct solar power from noon until sunset. This is the hottest part of the day, that part where you need the fan blades spinning at full speed.
