PV output

Is there a resource on the web that shows a typical panel usable power
output verses intensity of insolation. Also for a given panel and
latitude (51N here in UK) what average yearly output for the installed
capacity (sort of availability factor for average weather over the
year).

I have figures for a 73kW installed capacity with an annual
performance of 113,000 kWhr/year, which seems to be 17% of installed
capacity averaged over all the hours of the year, I was surprised it
could be so good. This from 1500 hours of sunshine per year, but how
much would be contributed on cloudy days?
