Did not measure it at that time, but normally peaks out at around 1040 to 
1060, depending on any haze etc.  This was not a scientific test, it was one 
of those "let's toss it up and see what it does" things. But it compares 
pretty close - but a tad higher - to other low-tolerance panels, such as the 
KC120.  Did not take any ground reflectance etc. into account. Our purpose 
was just to see how it compared with published ratings as compared to other 
panels.

At 7,000 feet, what did your pyranometer or Daystar kW/m2 say in terms of
insolation?
