[RE-wrenches] SolarWorld Poly

[Bill Hoffer]

Nik

I just bought a new mono solarworld 250 and it also has a new stle frame
with no feet, I believe they have switched to the new frame for all their
models now.  Limits options for mounting to only using top clips, not good
in my opinion.   I believe they are working on their own clip system, last I
saw it looked a bit "German" and a liitle too fancy for my tastes.  I have
not compared glass surfaces between the two models, but I would suspect that
they are switchign to the " cheaper reflective glass on all their new
models.  Cutting cost in one place and adding in another!  Over all thouh a
good solid module.
