None of these stories says how big the array is so it's hard to comment.
The picture looks like around 2Kw,
When they are installed the owner is provided with an assessment of
expected Kwh/year generated.

My first 4Kw array cost £14,000 and generates £2000/year so it's paid for
itself recently.
My newer array was £6000 but only generates £500/year.

why such a difference ?

Only the first one got the terminally stupid FIT subsidys.

Another one today wouldnt get any at all.

If £14K gives you £2k per year = £7k = £1k per year
then why does £6k = £500 per year

See above.

I have near perfect orientation. Someone who hasn't might get a lot
less.

So if the arrays are differnt what is this difference ?

See above.
