Thanks for your suggestions.
FYI -
The panel surface is clean.
IIRC, the batteries were at about 90%, based on my Balmar SOC display; a 12.7
volt reading
There is a controller - it's a Renogy 20 PWM.
I'll check the incoming voltage at the controller.
Not sure how to check voltage "right at the p

My panels were pretty filthy this spring and I was impressed with the
improvement when well scrubbed.

What kind of controller? What was the battery voltage at the time? Most
controllers have screw in terminal blocks, which make it easy to check the
panel voltage at the controller, which should be around 18-20V. If not,
check the voltage right at the panel. If it differs, then there is a bad
connect
If your batteries were fully charged the charge controller will not allow
further charging by the solar panels.

While yesterday was a bright, sunny day, I noticed that my 100 watt panel was
barely providing any power to my batteries.
Bought from Amazon, this panel [KingSolar, probably Chinese] was purchased and
installed in August, 2019.
I checked the MC connectors, they were OK.
Can anyone share their exp
