A wasting investment of £15000 needs to pay £600 pa just to return the

Is it? Harry's system has produced about that over, admitedly summer,
6 months...

One of the offical projections (given by the installers) is 3200Kwh
for the year.
I found out where they got it from (a website) There are several ways
of doing projections and all hangs upon the weather and many other
factors.
My own projection is 3700Kwh unless we have prolonged bad weather. I
read the meter ever night.

I have a near ideal site.
I believe the price cut will ensure that only better sites are used.
And of course in the sunnier parts of the country.
So Jocks and Taffs lose out again.
I will let youknow the grand total.
