I take it that's 1,200 "peak watts"?

Could you throw in what the actual "average" would be
over, say, a typical week? Including nighttime...

Thanks.

(In other words, do you get an average of, say, 200 watts? That
would, for this example, mean you get the equivalent of four
hours of full output/day. Yes, I know there's nothing at night...)

Thanks again.

So... given that your peak production is 1.2 kw, I guess
a back of envelope would be to take that number and
multiply it by 3 for a daily total?

(more in sunny areas, less in norther/rainy...)

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...)

Yet another gem of unintelligible writing from edateeng ghinius ghio.
