Lately, I have been spending some time on issues and solutions.

Today finally had enough sunshine to test my direct panel powered https://en.wikipedia.org/wiki/Corsi%E2%80%93Rosenthal_Box

Not able to use a typical AC-powered fan, used a 12V car/truck radiator fan, a DC17-55V to DC12V adapter, and a PWM motor module as both a power switch and speed regulator, 4 14x20 inch MERV13 filters and some old 2x2s to build the frame.

It moves a LOT of air at full power (~120W), but very much on the noisy side!
