Frequently Asked Questions

Does it work at night or on cloudy days?
The fan runs on real-time solar power and has no battery. Fan speed follows sunlight: fastest under direct sun, slower in low light, and it stops at night. Install it in a sunny, unobstructed spot with the panel facing the sun.
Is it waterproof? Can it handle rain and snow?
Yes. The solid metal shell is rated IP67 waterproof and tested against storms, heavy rain and snow. Wipe it clean with a dry cloth — do not flush the fan interior with water.
How do I install it?
Pre-drilled mounting holes on all four sides — simply fix it with screws. Choose a sunny location clear of trees and buildings, and face the panel toward the sun. No wiring, no batteries, no maintenance.
What spaces is it suitable for?
Anywhere up to about 2,500 sq. ft. that needs ventilation: attics, roofs, sheds, workshops, chicken coops, dog houses, greenhouses, cabins and RVs.
Does it need WiFi or an app?
No app or WiFi needed — it is fully automatic. As long as the sun is up, the fan runs by itself. See our Support Center for the full guide.
Do you ship to the United States? How long does delivery take?
Yes, we ship across the U.S. Orders are processed within 1–2 business days and typically arrive in 3–8 business days.
