So far is all good they work nicely
It is good that the fan is hybrid: it runs on solar when there is sunlight, otherwise it can run on AC power. The remote has good range and controls the fan easily. The fan runs very smooth and quiet. It really cooled down my house and saved a lot of electricity for air conditioning!
GREAT PRODUCT IT WORKS GREAT
Replaced a fan I’ve had for over 20 years, this was much more powerful and I purchased the dual power model as I live in the greater LA area, hot all day and night , I can hear the fan running if I listen for it, but it’s not an issue at all. I would recommend this brand, they shipped it fast and it was properly boxed, solid cardboard. The attic is definitely cooler and i feel like it’s helped cool the living area also by a couple of degrees, I still need to run my ancient AC but hey , I’m in SoCal so that’s totally expected.
Excelente producto.
Muy silencioso.
Inició a funcionar a penas recibió los rayos del sol, la velocidad de extracción depende de la intensidad de la luz solar cuando funciona unicamente a partir de la energía del panel solar.
