Solar attic fans are a smart choice for homeowners who want to save money cooling their homes in summer, prevent the attic “ice-box” in the winter, and extend the lives of their roofs. (learn more)
A solar attic fan uses photovoltaic panels convert sunlight into electrical power. The electricity generated is used to turn fan motor, exhausting air from the attic of a home. In summer, temperatures in an unventilated attic can exceed 160 degrees. A properly sized solar attic ventilation system will reduce attic temperature to 5-10 degrees above the outdoor temperature. Ventilating the attic reduces the amount of heat transferred from the attic to the home, decreases the load on the air conditioning system, thus reducing your electric bill.
The attic becomes warmest when the sun is the strongest. A solar attic fan runs the hardest when the sun is strongest. Everyday home activities such as cook and showering create moisture which collects in the attic and promotes mold and mildew growth, reduces the effectiveness of insulation, and attacks the wooden attic structure. Year round fresh air circulation from a solar attic fan removes this moisture and prevents moisture related problems. Zero operating cost.
