I Think i put it on the TODO first. Thought is was easier to connect to an arduino. Don't have time yet.

You can connect it directly to an Arduino analog input, but with a so low voltage output from the sensor, if you don't amplify it, you will get a very poor resolution (this is what the Solar / UV interface does).
I liked the sensor enclosure... nice idea. It seems that someone has started to industrially produce solar radiation sensors based on the method we discuss here for years!
Interesting these specs from a solar radiation sensor based on PV cells:
*Accuracy of monthly sums compared to a W.M.O. class 1 Pyranometer (e.g. CMP 11) according to ISO 9060: better ±5
*Very small drift of <0.3 / year (experience since 1989)
Have you ever opened the box of your sensor? What is inside?
