TAMKO’s Solar Attic Vent is a 20W solar panel that ventilates up to 1,600 square feet to prevent heat and moisture build up in attics. For larger areas, multiple vents should be used. Made of tempered glass, the vent operates from dusk until dawn without having to angle the panel toward the sun. The housing is molded with UV-stabilized ABS color-dyed plastic to prevent sunlight damage and provide stability. A stainless steel screen protects against insect and animals without impeding airflow. Four mounting options are available. tamko.com; 800.641.4691.
