Do yuo really want Lux?
The formula is 1Lux=0.001496 watts/sq. meter

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