Ensuring that you have the correct type of solar attic ventilation system is a definite guarantee for lower power bills. This is in addition to ensuring that your house is not structurally weakened due to uncontrolled moisture. This is because in the summer, warm moist air rises up in the house and without proper ventilation; gets trapped in the attic. Consequently, your air conditioning system attempts to counter this rise by powering up and your energy bills spiral up as a result.
The exact requirements of a sufficient system will largely depend on the type of house in which the installation is being done. A residential solar attic ventilation system for instance differs significantly in terms of design and costs from what would be sufficient for a commercial solar attic ventilation system. Solar Systems USA has a comprehensive list of both systems shipping at affordable prices as of the moment.
Solar attic fans are manufactured in two distinct varieties: those intended for installation on the roof and those more appropriate for installation on a house’s gable. The roof top variety is more prevalent and for understandable reasons. The roof top offers much better exposure to sunlight on many houses. However, if there are trees of structures shading the sun most of the day or the roof does not face the south, it may be more appropriate to consider installing a solar attic gable fan.
Experts in HVAC systems advice that your solar attic ventilation system should have the capacity to move the air in your entire attic out entirely every six minutes. This standard therefore serves to establish which system would be sufficient to effect such a capacity. The power rating of solar attic fans are indicated using the unit cubic feet per minute (CFM) to indicate the amount of air they can move out of the house in a minute.
In order to determine what fan will prove powerful enough for your home, you need to determine the size of your attic. Get the volume in cubic feet by multiplying the width, length and height of the room. You then need to multiply this figure by ten to determine the volume of air that the system must move in an hour of continuous operation. This figure should then be divided by 60 in order to arrive at the specific CFM rating of a sufficiently powerful solar attic ventilation fan.
Even if your home already features an attic ridge vent, you will still benefit from installing a solar attic ventilation system. To begin with, combining the two will ensure that your attic structures are not compromised by mould and mildew. This in turn ensures that the house will remain structurally sound for much longer. Owing to the fact that renewable energy installations have such a premium attached to them, you will also enhance the value or equity of your home.
For most homeowners though, what really matter is the amount of savings they can make after putting up considerable investment in acquiring the equipment and having it installed. According to verifiable research data, up to 44% of a typical American family energy costs are associated with heating and cooling the house. A solar attic fan system will help strike off a significant fraction of this cost without calling for any recurrent maintenance costs for a number of decades.
