William,
Almost everyone, including manufacturers, wants standard module sizes. There
are a lot of similar modules, but manufacturers produce different size and
shape cells (everything from 4-inch square on up and semi-square, round,
etc.) and customers have different voltage and current needs (everything
from 18 to 144 cell modules and up). It's like car tires. Lots of sizes and
models for all different kinds of cars and applications. Our best course of
action continues to be keep a file of the published module lists. Then ask
fellow wrenches what replacements will work and where to find them.

Subject: [RE-wrenches] Standard sizing
Friends:
Why can't the industry create a list of standard module sizes, sort of
like the battery industry has (http://www.rtpnet.org/teaa/bcigroup.html)?
This would be a big benefit to the consumer and the installer. If a
module of Group X size breaks, you are far more likely to find a
replacement if other manufacturers make modules of the same physical size.
Then the only challenge is to match electrical characteristics, but if you
find the same crystal type and cell count, you have succeeded. Who can we
advocate to?

PS: I have been saying this for years!

One or two Matrix/Photowatt PWX1250 needed, new or used, to replace
shattered module in a school demonstration system from 2005. Odd size and
shape, matches nothing else. Please reply offlist if you can help.
