Thanks HS...one note...you said:
I don't think it is hard to exceed the STC ratings of the panel IF (IIRC) you consider that the STC ratings are for flat panels, not tracking the sun.
The STC ratings are actually with sun overhead and not accumulated ratings...just output ratings and even done at nearly a mile high altitude so there is less atmosphere blockage so the STC ratings tend to be quite unrealistic on the high side vs. actual use. The California ratings measure off angle rays so tend to be more conservative and realistic for fixed panels but probably too conservative for adjustable ones. The right answer is probably somewhere between the two numbers but he main point is that you don't get more than 100 watts out of the panels...and you are lucky if you get close to 100 on a bright sunlit day with a still cool breeze blowing.
