Can someone try and please help me understand the black magic that is electric?

I have a solar panel at home with the following specs:

I am looking for the cheapest and easiest way to hook it up to a 12v radiator fan. The one I was looking at was 80w I think.

It only needs to come on when the suns out so wasnt going to bother with a battery, but will the 19v damage a 12v fan?

Do I need to put something in the line to regulate voltage or will it be ok? I heard solar doesnt always put out max voltage anyway?

If its cheaper or a lot easier to just get a new panel Id do that.

Thanks
 
Thanks for the info all. Im guessing 19v is the max output so probably with our weather it wont be pushing flat out all the time?

Funnily enough I actually found an old car radiator fan in the shed (not sure what wattage) so thought I'd try it as nothing to lose. I just wired it in directly and it seems to work. Pretty good power when the suns directly on it and slowly reduces when a cloud comes over.

If I wanted to put an inline on/off switch on it would that have to be anything special or just find something the correct size?

I think I may actually need to double up with another fan so think ill watch how this goes for a few days and as long as its not on fire or anything will probably do the same. Fans seem cheap about £20 and panel about £70 on amazon.
 
Ghetto solar fan was exactly how I described it to my mate ha.

Thought about a battery as we usually have a few lying around, but would it have enough juice to charge the battery and run? I read that if it keeps draining the battery it wont last all too long? Would be ideal though.
