I think I understand now... So to measure the real voltage put out by the solar panel, I would put it on the ~V (20) setting instead of the Battery (9v), right?
I've got a $3 harbor freight special multimeter with a "battery checker" setting. It actually says "1.5V(4.0mA)" and "9V(25mA)" on the dial, so I've always taken it to mean "how much balls the battery actually has left" (like you said, a stress test). Just cause a battery still puts out 9V doesn't mean it has any oomph behind it.
What I don't get why it's labelled "mA" though. A standard AA should be capable of putting out quite a bit more than 4 milliamps I thought.
Fun with cheap ass tools. That's why I also have a Fluke that's near as old as I am for checking real things ;)
Ya I bought a cheap $20 Meter from Amazon.com that tests the usual Voltage Amps and Ohms plus it tests Capacitors and Transistors and has a larger range in each scope than other more expensive ones that were available at Amazon.
It sure beat my old $20 Radio Shack one hands down.
