I'm trying to cobble together a small exhaust fan, solar powered. I have a bunch of old computer fans, both 5v and 12v, and am having trouble figuring out what I can run and how much panel I need. M...

Computer fans are amazingly durable. A 12v fan will run as low as 7v no problem or as high as 17v (from my own experience). They are electronically commutated so the winding switch on and off as needed to make it spin.
Low amps or volts will not harm the fan. They have protection against that as well as a locked rotor.
High volts will eventually kill the microchip inside the fan.
For these tiny DC brushless fans voltage is the only thing that matters. They'll not draw more amps than needed.
