If that is @timselectric Roof ! - he is the only one I have seen that cut holes in (defective) panels, sure turned out well!
Not sure how a working PV panel could be trimmed, I mean think about how we work to get Series and Parallel set up, how in the world would this work if you can cut a bit off a panel? How would the connections be repaired in the panel? how would the cut edges be supported?
