I have a couple of Arco 16-2000 modules, that I examined this
morning. These puppies are rigid. We are racking some Sharp 235
modules at this time, and we are careful not to flex them. The
Sharps have good frames compared to many others. The 16-2000 modules
are extremely rigid. This discussion has increased my appreciation
of the value of rigid module frames.

About half the spec sheets that I see list glass thickness, but only
a few companies mention cell thickness unless it is in a press
release. For example
<http://www.pv-tech.org/news/_a/ldk_solar_becomes_largest_wafer_producer_outlines_technology_roadmap/>http://www.pv-tech.org/news/_a/ldk_solar_becomes_largest_wafer_producer_outlines_technology_roadmap/
Even if they do mention cell thickness, it may be for older modules
or soon-to-be-released modules and not the modules that you buy.
Some people say that thinner cells are more flexible, that they will
bend before they break wjhen encapsulated in the laminate. On the
other hand thinner cells are more fragile and break more easily in
handling. Micro-fractures look like canyons under a microscope and
act like canyons to electron flow.
