Hi Geoff,
In regards to the performance between Unisolar and crystalline, there
is a side by side ( same watts, batteryless intertie with metering)
installation up here on the North coast of California, and the the
Unisolar is the constant under-performer. This includes cloudy,
sunny, warm, cold weather.
I have seen nothing in the field to support the Unisolar claims about
better performance in low light etc. That said, they do work better
in very hot conditions, if thats what you have.

As a follow up to my uni-solar post (and thanks to all who provided
feedback), I have a second request:
Any references to recent side-by side "shoot-outs" between Unisolar
and conventional crystaline PV? Scientific studies? Your own
wrench thoughts?
I am more and more often encountering confused customers that are
considering unisolar systems at zero-tilt (we are at 40 degrees N),
with plenty of partial shading, after getting a pitch about all
sorts of advantages of Uni-Solar. I think that this product has
it's role and I occasionally sell it... But I am frustrated when I
truly believe I can deliver a better net energy production with a
tilted crystalline solution (avoiding the shaded areas).
For a brighter energy future,
