1.67 mv/W...hmm, at what I remember being 200W in full sun, that's
not a very high voltage signal. I don't think you can change the
reference voltage for the mica ADCs so you may need an amplifier
to get a decent conversion range. A simple op-amp oughta do it.

Otherwise just doing a straight-forward ADC conversion with
getData() and dataReady() should do the trick just fine. See
the Oscilloscope and Sense demo apps.
