Fans are nearly ideal for utilizing alternative energy power loads. They can run directly off DC current (as with all of the following products). These power fans run when they are most needed, when the sun is shining. During summer months, your 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, garages, kennels, barns and attics where AC power is not available. The sun powered 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 module, the fan begins to operate. The 12" and 16" fan kits include fan, solar module and 20 feet of two-conductor wire. And this is a green energy product.
