14 inch DC solar attic exhaust fan solar powered auto cool fan adjustable fresh air vent

The solar panel on the fan top produces enough electricity to power a spinning fan in the round ventilator on the roof behind the panel. The fan works when the panel is basking in sunlight.

Solar roof fans work on a very simple principle: circulate the hot air out and get the cooler air in. They work with the energy from solar It's not only environmental but also energy-saving.

30W polycrystalline solar panel (415x495x25mm),

19.5V brushless DC motor,

14'' Aluminum fan blades (air duct dia. 368mm),

square shape fan cover, square shape fan base,

durable ABS Nylon 7-blades, pull out high speed and high preasure hot air

wind guide cone and blades structure, leads the air come out fluently

This waterproof controller is like a little smart computor, the solar wattage output becomes its signal so that it can sense when sunlight is weak, and then it switches in the back-up power to power the fan together with the solar panel. Not any solar energy is wasted, meanwhile, fan is still running fast.

And you may decide Battery or Adapter as back up depending on whether there is convenient AC grid in your location.

The clever design for the solar roof fan is to get the sun to do double duty. It makes perfect sense to make the sun cool the roof space, since it is the source of the problem in the first place. In any event, you are doing the right thing by trying to use a solar-powered fan.

Roof venting is an important aspect in maintaining a healthy energy efficient environment. Proper venting cools roof extending the material life and reduces the load on the air conditioning system. Roof venting also increases fresh air circulation.

Powered completely by free solar energy, this sleek and efficient vent is both compact and quiet. Fully operational right from the box, it installs easily, with no electrical wiring. And let's not forget powerful!
