insolation tables, interpretation

[Robert Morein]

Are the table values the watt-hours per square meter of earth surface, as
opposed to a panel with a more optimal orientation?

Which table are you looking at? Most will have some preface that explains
your question.

http://rredc.nrel.gov/solar/old_data/nsrdb/redbook/atlas/

Allows you to pick from several possible collector orientations/designs.
Including a horizontal plate, vertical plate, mounted at latitude etc...

I'm just trying to imagine any kind of reputable table that wouldn't
clearly explain what the data represented.

Of course one would have thought that a PhD candidate in Engineering
would be capable of deciphering such info.

Thank you. Apparently there is no single standard interpretation.
Some tables imply that the values apply to an optimally oriented surface,
ie., a panel mounted on a tracker.

damn, there you go again asking another question you already knew the
answer to.
