yes, which is is inaccurate.

how do you figure? are you trying to figure a daily average from two

Just ttrying to get a back of envelope rule of pinkie
as to how much power (over a decent time interval)
we'd really so from a solar panel with X peak production.
From your figures (and others I've bumped into) it
seems like taking the peak and multiplying it
by 3 or 4 hours gets you a number close enough
to back of enveloping.
(obviously you'd have to do more work before a final spec...)
Knowledge may be power, but communications is the key

That's assuming that in most areas the sunlight hours are 3 or 4. It
is more easy to simply multiply by the number of hours to get a rating
in kwhr. The average should perhaps be taken over at least a couple of
weeks of course winter months are different than summer, etc.

Question: Are some panels more efficient than others? Is there a price
to efficiency ratio - as in ''this is cheap but less efficient....that
costs more but gives higher efficiency'' efficiency being perhaps
measured in candelas of luminous intensity from Sunlight leading to so
many watts of power
