Measuring Solar Radiation based on Photovoltaic Cells

Hello,

I have now build the Solar radiation sensor and fine tuned its calibration.

At first I had a gain of about 26 (assuming the same values taken in the example published in a different post on solar radiation measurement) and at mid-day the values read were capped at 1400W/m2 in Cumulus. So I've adjusted R1 and R2 to get the exact values giving me a gain of 6.875. Then I readjusted by measuring the PV cell output at a constant irradiance and reading the board output to get the same gain.

Now the values are pretty similar to the national irradiance map published here in Singapore and refreshed every minute! It's a color mapped, so not extremely precise, but when the zone of my weatherduino is of the same color as the neighbourhood, we can deduce the value of the irradiance. I still need more fine tuning though.

My question is on Cumulus: how to adjust the original green gaussian center? Currently it's entered at 3am.. I need to center it around 12pm, right? I tried to find some configuration on the trendT.html or the js files but no success.

Thanks!
