Solar Attic Fan For Residential

Adding solar attic fans to your home can protect it from seasonal damage and can provide modest energy savings. Running wiring to the attic can be a pain, solar can simplify the problem. We will discuss what to look for while install your solar attic fan.


Make sure you have good soffit ventilation around the eaves of your roof. You will want approximately 4 sq./ft. of free intake (fresh air) per fan. If you have a grill or holes covering 50% of that intake, then you want to consider 8 sq./ft. per fan. This is also important because you don’t want your solar attic fans to draw air conditioned air through your can lights in your house. You want the fresh cooler air coming in from outside.


You want to place your solar attic fan ideally on a slope facing sun. If you don't want to see the fan from the front, and the front is facing the ideal direction, please use our 40W or 70W tiltable fan. You can install them on the back of the house (facing any desired direction), and then use the tilt panel function to tilt south or west (or "lay flat on the ground"). This will maximize your motor power.

Try to place the fan in the center or "middle" part of the roof. Remember that you want to draw cool outside air from the soffit (or gable) and let it flow through the attic. Although you can use 2 or more fans to enhance the attic ventilation, please make sure you have enough air intake. Also, as mentioned earlier, keep them about 5 feet away from the ridge holes (or other open holes).


Solar powered attic fans are a simple and effective way to protect your attic from weather related damage. There are many factors to consider when install a solar powered attic fan for your home. Usually we need to take attic area, roof pitch, good soffit ventilation and installation position into consideration.
