Measuring Solar Radiation based on Photovoltaic Cells

Not really. But I guess you may find food for thought in PVsyst's documentation where models used and calculations done are explained: http://files.pvsyst.com/help/index.html

"muIsc (often named Alpha) is specified on the main page of the parameters, and used as such in the model. For crystalline modules, its value lies usually between 0.04 and 0.08 %/°C

muISC = temperature coefficient of the photocurrent (or short-circuit current) / temperature coefficient on Isc [mA/K] or [%/K]"

etc...

Judging by the above, it would seem we could get an error anywhere from ~1,6% to ~3.2%, depending on the cell used, under 65º Celsius (0,04-0,08*40º difference from reference temp.).

For instance, if I do a simulation of the panel I am currently using to power the WeatherDuino under 1000Wm2 it should have a short circuit current of 5,34A at 25º TOper and of 5,42A at 65º (+1,5%, muIsc=0.039%/ºC).
