Difference?

here is what the product management staff had to say:

"The highlights are the modules can now be used for end mounting, the load capacity is higher, and these now come with a 25 year warranty (standard). The only difference in the modules is that the frame is actually .4 inches deeper than the original KD135. "

what this means for practical purposes, is that for unirac systems, now dark F clamps will be used instead of C clamps. 

for ground and pole mount systems, you may have to check closely to make sure none of the mounting holes have changed positions.

the old frames are being phased out, and all kd modules will eventually get the new frames.

to the best of my knowledge the cells and therefor the electrical characteristics have not changed.
