i now do not have access to the pyranometer as i'd returned it to my friend already, probably no where near to borrowing it in the next few months. maybe i'll try to redo with a lower resolution first (ignore op amp) and think about using a different op amp next time
If now you don't have access to the pyranometer data, you can try to find some nearby weather stations with reliable Solar Radiation data, and try to calibrate your device with those data. This should be done only in sunshine days, with a clear sky, otherwise in cloudy days the readings significantly change from place to place.
