Hi Allan, 

That is about the dimension of the Panasonic/Sanyo if you want to up the
output too!

Subject: [RE-wrenches] 72-cell modules

 

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
