not on for a wild goose chases.

I guess no one here knows much about solar panels or charging 3 AA cells
and what is needed.



Well, your weather station isn't a low cost unit from Walmart, so it's
not exactly fair to flame the rest of the world for not having THE RIGHT
ANSWER at the tips of their fingers. You haven't said anything about
your electronics knowledge. If you have none, or very little, you might
be out of your league from the start.
Now, do you have a multimeter of any sort? Have you attempted to
measure the unit's charging voltage and/or current? How about measuring
the solar panel's voltage in full sunlight? How about the voltage and
current (if any) it's putting into the charge controller?
Knowing that information can tell you whether your problem lies with the
batteries, the solar panel or the charge controller. Chances are that a
schematic is not available for your station. You might send an email to
the manufacturer and ask for the schematic. That little piece of paper
could be invaluable for you (of someone who is able to read it and
determine where the problem lies.
Just guessing here, but if the unit uses 3 AA cells, that means that the
solar panel will likely be rated for 6 - 9 volts open circuit, at maybe
50 - 100 mA.
You need to make some voltage and current measurements and report them,
then someone might be able to help you get it going again.
