Hi all,

We are looking for real-time hourly solar radiation data (global
horizontal) during 2009-2010 for PV performance simulation. I tried
different places including the follows but unfortunately no one has any data
of hourly solar radiation:
E+ Reatime weather data request:
http://apps1.eere.energy.gov/buildings/energyplus/cfm/weatherdata/weather_re
quest.cfm
National Climatic Data Center:
http://lwf.ncdc.noaa.gov/oa/climate/climatedata.html

I also checked TMY3 original data files, which only have the data until
2005.
Can anyone please give me some advice? Is there any latest weather file that
has as many data as in the TMYs?

Thank you.
