Not sure what this is worth, but with most Kyocera modules that used the same size cells (but different amount of cells per module) you could wire many different VOC modules in series as long as the total number of CELLS per string was the same. It wouldnt matter what the individual module ratings were (as long as the total array was mounted at the same tilt and azimuth, an MPPT charge controller wouldnt know the difference. Ive done this many times with grid tie inverters, and honestly it wouldnt make a difference with a charge controller either. Different age cells/modules may make a slight difference. But what Im suggesting is to count the cells in the strings.
Hope that made sense.
