and i want to hook this upto a solar panel. And this thing works way better than the solar kings by 100 yards. i keep seeing these set-up that have a expensive regulator, that is hooked upto a car battery, and it just goes on and on. i just want it to turn on when the solar panel is touched by the sun and that this is then wired into this 8 inch extractor and turns it on. if these solar kings can do it, it cant be that complicated. I'm aware i will need bigger solar panels to run this, but can someone give us a clue on how to get this up and running the way i want it to..........with no risk of fire.
cheers

That link you provided shows a AC powered bower fan. The solar panel isn't going to remotely run that as it is.

An AC powered blower will need large panels, charging several batteries of matched sizing, along with a regulator and a inverter to take care of the switch from DC storage to AC power. A totally inefficient way to do it.

Did you ever think about using a 12-24V DC powered marine engine bay blower sold at a marine chandlery (Whitworths) even then a solar panel will probably not have enough power to overcome the spindles resistance in the motor to start it.
Hence why its so hard to build a proper solar powered 12V air conditioner with out banks of batteries, a huge solar array linked by regulator.
