Come, let us find out about some of the most acclaimed solar attic fans that you will get to see in the marketplace today!
This particular solar roof and attic fan manufactured by Solar Blaster is solar-powered and has galvanized vent. You can get the instructions for installation with the purchase. The solar panel is secure. This item is a perfect choice of ventilation for your garage, garden shed, greenhouse, home, storage shed, utility shed and also dog house. The fan comes pre-installed on a galvanized 8” metal can roof vent with flashing (16.5” x 16’5”). A 3W solar panel is fixed to the top surface of the vent hood with four exclusive, stainless steel clips and wired to a two-ball bearing, 2700rpm, airflow capacity of 39cfm fan is rated for 50000 hours. The metal vent is to last a lifetime as compared to plastic vents found in other similar products. This is so because plastic is bound to fade and get brittle over time, more so being placed on a hot roof.
Installation is similar to similar products and it does not allow you to install fewer vents. The solar power is used to boost the effectiveness of the passive roof ventilation system. One fan is required for every 600 sf roof area. So a typical home of about 1200 sf would need 3 – 5 vents. The ventilation should be uniform across the entire attic space. This is the reason that most homes have numerous ridge venting or passive vents installed.
It works in a way such that cool air comes in from the eave’s soffit vents, move along the total roof deck so as to move out at the top through the passive vents. The uniform movement of air will keep the deck of the roof moisture free and dry. The insulation’s r-value is also kept from falling due to condensation dripping down from the roof deck. The fan does not include an on/off switch or a thermostat and the same is not needed. The fan is to run in summer to remove the heat and in winter to remove moisture due to condensation.
