Solar Panel used in Conjunction with a DC to DC Step Up
I'm assuming that you tested the panel voltage into an open circuit (just test leads across the panel) and the panel current into a short circuit (again, just test leads across the panel). This is not a valid test. When you put your ammeter across the panel, it acts as a short circuit. So the panel is putting out 130ma at almost no voltage!

As soon as you connected the regulator to the panel, it drew enough current to pull the voltage below what it could handle.

Look at it this way: a 1W 6V panel will put out 1/6 amps (167ma) at 6V in full sunlight. There's no way it's going to put out anywhere near that in dim light.
