How does a solar power exhausting fan work?
A solar powered attic fan coverts the sun energy into electrical power by using a solar photovoltaic panel. The dc motor of the exhausting fan would be turned to run by the electricity generated by the solar panel, and start to exhaust the air in the attic of a house.
Proper air ventilation system is in demand when the indoor temperature rise up to 165 degrees F during summer time. and the solar attic fan could help to reduce the attic temperature of 5-10 degrees F. It not only helps in reducing the electric bill by decreasing the load of your air conditioning system, it helps to balance the indoor temperature and increase the life of the roof materials.
The roof life could be expended. During winter, moisture and mildew could be caused since the attic heat get trapped and the snow get melt on the roof, when the attic area is not well ventilated, the moisture find their bed of growing. Sometime ice dam would comes alone in the color eaves. The solar attic fan helps to run the hardest and refresh the air when needed. The maximum vent speed could be up to 1950 CFM which could help in a attic area of 20 SFT. Without taking any civil power consumption, the solar roof vent does not need any electrical wiring, so it only takes around 1 hour for a easy installation.
