So i bought a brand new 12 volt solar panel that retailed for $ 170 for only $ 5.00 at a garage sale a few months ago http://www.batterystuff.com/solar-chargers/PF12w.html
and what I would like to know is how many 12v devices fans/lights etc… you can run before you start running into reduced power issues resulting in reduced performance load

You won’t be able to run much. Use it to charge batteries so you can run LV lighting. The problem with 12v devices is that they draw a lot of current- more than a solar panel can efficiently provide.
It depends on how big the panel is and how many watts it puts out.
The one on your link will probably not run much of anything on it’s own. But over a long period of time it could recharge a battery. In other words if you recharged your battery all day long in the sun then you might have enough power to run your fan and light for an hour or two in the evening before it went dead.
available in 6.5, 12 and 25 watt versions.
for each device look on the info plate and find out how many amp’s they draw
Watts = Volts x Amps
hope this helps
from a old timer
your panel will say how many watts it is, then look at what you want to run, if the panel is more than the device it will work
