If we are generating plenty of excess power in the summer, sold at a premium, then it all makes much more sense.

My only concern would be panel positioning on a system that large and how many panels are going to be in sub optimal positions. If most of those 46 panels are south facing it would make good sense but if you start dealing with other exposures it might alter generation capacity quite a bit and then your cost/benefit can vary quite a bit.
