Solar Attic Turbines
Attics build up heat from the solar radiation and hot roof surfaces that can add to your heat load. Convective currents will cause the hot air to rise and vent out of the attic if there is adequate air intakes from soffit and gable vents, as well as exhaust vents to allow the heated air out. Most older homes were built with little consideration of attic venting and suffer heat buildup problems in the summer and moisture problems in the winter. Good attic ventilation is needed year around. Passive exhaust ports allow air to escape slowly. Wind driven attic turbines help draw the air out of the attic at a faster rate during windy periods, but are less effective in period of no wind and even leak during drizzly rains. Power turbines work well, but is using electricity to save electricity really the answer? Solar power attic fans use solar energy to help ventilate the attic without adding to your electric bill. The perfect thing to keep your carbon energy footprint small in this day and time.

Photo voltaic solar cells provide electrical power by exposing silicon wafers to sunlight and it frees electrons to flow through the electrical circuit as Direct Current (DC). This electron flow powers the attic fan for ventilation.
