I took the 1076KW to be the maximum output of the array.

Could be, with 800 panels that would put each at 1.3kW, aren't most
domestic ones 4kW, three panels so same theoretical ballpark ? (or
maybe six, dunno I don't pay them much heed).

The panels are usually quated a speak output in our climate. My panels
are185 w each which is on the larger end.

In most of Scotland they will get 790 Kwh/year for every installed
KWpeak.
In the south of Jockland its 830.

There is another not often mentioned factor.
If you put the panels on the roof they take up no space.
If you put the panels on the ground, they take up space that has to be
paid for and there is a lot of concrete etc.. Also the ground round/
under the array will need to be maintained. (Mow the grass?)

But there is no scaffolding cost and any maintenence/repairs are much
easier.

TurNiP keeps telling me I need to wash my panels down daily.
I never wash my car, why shouldI wash these panels?
It rains don't it?
