During summer months, attic temperatures can reach 150 F. High temperatures cause an increase in temperature in the living space and an increase in energy consumption by air conditioning equipment. Forced ventilation will circulate cooler air through the attic space and lower the temperature. Fan and solar module combinations allow daytime ventilation and air circulation anywhere the sun shines. They are great for greenhouses, kennels, barns and attics where AC power is not available. The solar module runs the fan at full power in full sun and at a slower speed in overcast weather.
Operation is automatic.
When the sun shines on the solar module, the fan begins to operate. The Attic Roof Ventilator is self-contained. Fans are nearly ideal solar powered loads. Solar powered fans run when they are needed the most - when the sun is shining. These 12 and 24 VDC fans are quiet, powerful and use very little power.
