"All of my panels just have water tight buss boxes."
Junction boxes are just fine for previous installations and are probably more durable than the MC4s (Multi-Contact 4mm square), IMO (expected aging of MC4 latches). The NEC requirement for locking/latching connectors was yet another attempt to dummy-proof installations. We continue to use combiners for installations with much charging current anyway (looks like a 10-amp MC4 cable limit with voltage drops being even more limiting and to be considered in advance of that).

The reference was the energy cost. The amortization schedule is short. The components that replace gas were all of $135 or there abouts.

It wouldn’t be a union installer. They mostly work on industrial scale solar.
