Hi,
Basically, you need to wait for a day with "clear blue sky" and create a graph with a shape as shown in post #1 of this thread. Then you can compare the peak level with the "maximum solar radiation" curve shown for the specific date and your location, using software such as Cumulus (in post #1) and apply a calibration factor as required.
Cheers, Alan.
