Is There A Way To Measure Thou Output Of A Solar Panel? Like With A Voltmeter Or Something?

You would measure the solar panel in terms of the open circuit voltage and short circuit current.
Open circuit voltage – use a voltmeter to measure the voltage between positive and negative terminal of the solar panel
Short Circuit current – measure the current by inserting the ammeter between the positive and terminals of the solar panel.
FYI solar panels are modeled as a constant current source up so just make sure your ammeter will be good for the current going through it.

you would need a load on the panel.. not too small and not too huge. I would try a 10Kohm resistor and put a volt meter on it, that way you know both current and voltage.
you are going to find out that they ARE in fact frequency (color) sensitive.
