Sorry to hear about the BP problems Andrew. For what it's worth you
can tell BP that your story just solidified another wrench's reason
to never sell any of their modules ever again.
Hope you get the customer service you deserve,

Greetings wrenches! We recently did a small commercial system (17
kW) using BP-SX 3175 modules and the Unirac RapidRac ballasted
mounting system. The flat roof is ballasted with 2" of gravel
that we smoothed as much as possible but undulations are visible
in the array, though the changes are never more than 5 degrees
from module to module. After about 3 months the cusotmer noticed
a problem developing with 1/3 of the modules: the interior of the
module (backsheet, cells and glazing) were separating from the
aluminum frame! Remnants of the black, rubbery adhesive are
clearly visible on the inside of the frame and on the edge of the
backsheet/cell/glazing sandwich. It seems clear to us and that
the adhesive simply failed and should be covered under the 5 year
workmanship warranty, but BP does not agree. BP is saying that
the modules are supposed to be mounted with a solid member spaning
the width of the module and since the RapidRac supports the module
on what amounts to 4 individual stanchions, the workmanship
warraty is null and void. The mounting instructions, however, say
nothing about requiring a solid member spaning the module.
Has anyone else had this issue with BP or any other types of
modules? Does anyone buy that it could be the fault of the
RapidRac? We unbolted a few of the bad modules to see if the
frame was exerting any torque but the neither the module not the
frame moved - we set the module back on the frame and the mounting
holes lined up perfectly as before.
Thoughts or suggestions?
Gotta' love these long sunny days!
