Alan,
SunPower's 240W module is 72 cells and the physical size you are looking
for.
Not sure how the voltage will work for you. Good Luck.

Wrenches,
About a year ago I asked for suggestions of 72-cell modules with 125
mm cells - the standard 155-195W modules of just a few years ago. Now
we really need some.
We have a good customer for whom we put in an off grid system in 2006.
48V, 27 BP SX170 modules on three Wattsun trackers. Each tracker holds
nne modules, wired as three 72V strings of three modules each.
Yes, the notorious SX170s. Four with burn spots were replaced in 2008,
6 more in 2010, and now ten more failed or are showing discoloration.
BP's warranty contractor has agreed to replace the wattage equivalent
of 23 of them at $2.00/W. They will either ship us replacement modules
or send a check for purchase of replacements elsewhere. The problem is
that their only offerings are 60-cell modules, which won't fit the
trackers.
BP got out of the solar business before the standard configuration
went to the larger 156 mm cells. I would have appreciated a serious
corporate effort to procure warranty stock of modules that were most
like the ones manufactured by BP, so that they would more readily
replace their warranty failures. That apparently is not to be.
The SX170s are 31.1 (790mm) by 62.8 (1593 mm). I need to locate some
72-cell modules in this standard dimension range. We'd probably buy 27
of them, once we determine that the replacements can be fit to the racks.
Can anyone suggest a brand/model/supplier etc.? I have seen that
Eopply shows 195W mono modules in the U.S. section of their website
(thanks, Chris Daum) and I'll call them in the morning. Any other
suggestions, please?
Thank you,
Allan
