Did some test today
Voc 19.75 (label says 21.6)
Isc test with leads in the plug 0.0 amps
test by short circuit with clamp meter 2.85 (5.74 on the label)
not sure what it means. panel bad?
The panel heats up when the sun is on it, so it has lower Voc, like the 20 you are getting.
Amps depends on brightness of sun and you get less with sun off angle, most with panel aimed right at the sun. The 2.85 could be right for the conditions.
Not sure what you are getting there with plug vs clamp-on readings. Might be wrong setting on the multimeter in the plug? Or a bad plug is the reason you are not getting amps through to the battery?
It is possible to get the voltage but have trouble with the amps if there is something wrong with the wiring ISTR
