There is a fundamental problem with the maps.  How do you figure out
which way is true north?  If the top of the page is true north, then
that should be labeled, otherwise place  a N-S-E-W indicator somewhere
on the map.  Thanks,

Jon

Taken directly from the Google Maps User Guide:

"Press the up arrow on your keyboard to move north"

http://maps.google.com/support/bin/answer.py?answer=68259

So, that partly answers your question.

The remainder of your question is answered by this.  As a rule, maps
face true north.  (It may, in fact, be every map.  But there are
always exception to the rule, so I cannot promise it.)

Up is true north on Google Maps.

If you want to know for sure, note what you see on Google Maps with
compass in hand.

Well... this points to the heart of the problem, NWT.
Compass north is NOT "true" north.
For North America, as an example, true north declinates from compass
north by >20degs W on the east coast, to >20degs E on the west. Which
means, here in Oregon where I am, "true north" is actually ~17 degrees
more westerly that the compass says it is.

See http://www.thecompassstore.com/howtouseyour.html
and then compute your location's declination here:
http://www.ngdc.noaa.gov/seg/geomag/jsp/USHistoric.jsp

This comes very much into play when you're trying to orient solar
panels, and such.
I have not been able to determine yet whether "up" on Google maps is
magnetic north or true north.

Take a moment to carefully reread everything I said...

You should NOT use Google Maps to orientate your solar panels...
