I have seen a publication or reference which had historical data for
'days of available sunshine' for various cities in the US. I would
guess that this is very basic information for designing a solar
photovoltaic or thermal system. Can someone suggest a source for this
information? I know the Weather Bureau has collected this information,
but they want $100s for it.
Thanks,
Karl
