<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>You might check in with the monitoring companies you work with to see if they can pull up the data from one of your sites with an irradiance meter. You might already have this in an admin view. If not, maybe someone on this list does. <BR>
<BR>
NREL or Sandia may also collect this data on an ongoing basis. While I’m not sure who you’d contact, there are extensive resources listed at the end of the Production Modeling article in SolarPro. That issue will post online this week & start mailing very soon. <BR>
<BR>
I also suspect 3TIER has the data you want (<a href="http://www.3tier.com/en/">http://www.3tier.com/en/</a>), but I’m not sure they’d give it away. Since you’re not planning on making money with the data, maybe they’ll share. Doesn’t hurt to ask...<BR>

David - Thanks! This is great as an average for comparison. Any thoughts on where I could get data specifically from 2009 or the last couple of months?<BR>

It includes information on TMY (typical meteorological year) data, like that published by NREL here:<BR>

Is anyone aware of a resource for finding local historical irradiance data? We've had a cloudy winter around the DC Metro area and I would like to quantify how far down we are from the average for new customers concerned with production.<BR>
<BR>
<BR>
Thanks in advance,<BR>
