I should’a knowd that phyxics just ain’t that simple, and now that you’ve
sent me the formula, I need to go find out what  AM1.5 means on a clear day
in Kansas with a humidity of xx%. My brain gets fuzzier an fuzzier. Thanks
Chris.

Do yuo really want Lux?

The formula is 1Lux=0.001496 watts/sq. meter

 

Module performance is generally rated under standard test conditions (STC):
<http://en.wikipedia.org/wiki/Irradiance> irradiance of 1,000
<http://en.wikipedia.org/wiki/W/m2> W/m², solar
<http://en.wikipedia.org/wiki/Spectrum> spectrum of
<http://en.wikipedia.org/wiki/Airmass> AM 1.5 and module temperature at
25°C.

Off the top, can anyone tell me how many lux of sunlight represent 100% of
STC? 1000 watts/sq meter?
