Tamko's Solar Attic Vent harnesses sun power to keep energy costs low with a 20-watt solar panel. The fan can ventilate up to 1,600 square feet and operates from dawn to dusk without having to tilt toward the sun. An optional cold-weather thermostat is available and will disengage the unit when the temperature falls below 50 degrees F. Customers can choose from four different mounting options, including one that allows the solar panel to operate the fan remotely. 800.641.4691. www.tamko.com.
