Thanks for the effort and report.
I'm gonna guess these test where made on Oct 14, 2013 based on the data from U of O (Portland), click on chart recent data, then previous chart back to 10/14/13.

And looks like in the fall at 46N latitude, I’m getting about 135 Watts from a nominal rated 160W panel, or about 85%. Sounds pretty reasonable to me, but would be interested to know what others are getting under similar conditions.
yes, the data was collected on Oct 14th and 15th, amazingly we had absolutely clear skies on the 14th, a few wispy clouds in the morning and evening on the 15th. And there also was NO noticeable haze either. Summer "clear" skies in portland start to get hazy after a few days due to pollution.
