The skepticism is fair because the market is full of underpowered fans glued to roofs with no intake support. Those fans really do not move much air.
The physics is simple. Hot air rises. If you give it a powered exit at the top of the attic and a clear intake path at the bottom, it leaves. A 30W solar panel spins a brushless motor that pulls a steady column of air. On a typical 1,500 to 2,500 square foot attic, that means several full air exchanges every hour during peak sun.
Homeowners report cooler upstairs rooms within the first week and lower bills by month one.
The failure cases are real. Tiny 10W fans with no intake support do almost nothing. Fans on shaded roofs do not get the power they need. Fans on attics with blocked soffits stall out. That is why we size the fan to your attic, check soffit intake during the walk-around, and only book installs on roofs with usable sun exposure.
