Well... I hate to back down from a challenge, but I am a n00b. I'm not a complete n00b but anything I do from here with this project would require a lot of help from you (SGT Wookie) or the forum and I fear my avalanche of questions would get old... And with my application I (think) can tolerate quite a range of light output from the declining voltage of a discharging battery. Just as long as both arrays have exactly the same output. I'm going to test the simple version that I have and probably build the low-voltage detection circuit posted by TKNG211 and add it later if the array works like I think it will. I appreciate all the help so far Sgt Wookie but I think I'll have to pass on your challenge.
I've got my array soldered together, I'm just working on the wiring now.
