Award winning, professional grade and high wind approved solar powered attic fan can continue to run after dark with the included Solar Controller.

The Solar Powered Attic Fan 1012TRS/HW is designed to reduce heat build-up in your attic in the summer and remove harmful moisture in the winter. Its commercial grade, heavy duty construction provides up to 25% more power than other fans, providing better circulation and improving airflow in your attic space. The 1012TRS/HW is approved by the Florida Building Code and Texas Department of Insurance (TDI) for high wind situations – tested over 150 mph with solar panel in full tilt. One fan can ventilate up to 1550 square feet and lower the attic temperature so your air conditioning won’t have to run as long to cool your home. The Solar Powered Attic Fan qualifies for 30% Federal Tax Credit with many other local utility and municipality rebates available.

Reduce attic heat build-up – 43% of air conditioning design load is based on high attic temperatures. Lowering attic temperature lowers air conditioning use.

Reduce damaging moisture in your attic – 28 gallons of moisture is typically added to your attic space throughout the winter. Attic moisture causes mold and mildew growth and can cause attic insulation to lose its effectiveness.

The Solar Controller, with 2013 upgraded software, allows you to monitor your attic fan’s operating status, attic temperature and attic humidity. The addition of the Solar Controller enables your Solar Powered Attic Fan to run intermittently after sunset, or when there is no light available from the sun – improved for 2013, operating on a cycle of 15 minutes on, 15 minutes off for up to 10 hours or until solar power becomes available again. This will allow your attic temperature to continuously drop after sunset and help remove the hot, stagnant air that can build up on those warm summer evenings. The annual operating cost of the using the Solar Controller connected to house power is about $5 a year.  As an upgraded electronic thermostat and humidistat, the Solar Controller also allows you to take control of your Solar Attic Fan’s thermal switch remotely with the hand-held remote control.

Solar Powered Attic Fan qualifies for a 30% Federal Tax Credit with many local utility and municipality rebates also available.

The Solar Powered Attic fan is easy to install – less than 2 hours for the typical DIY’er. No electrician, permits or inspections required. National network of U.S. Sunlight preferred certified installers available, call 1-866-446-0966.
