Considering The Alliance Delta 252RL. The solar package mounts a single 200 watt panel near the rear of the roof. The wiring penetrates the roof near the panel. It’s my understanding the wire enters a 1 1/2” ABS conduit at that site. Can anyone confirm that? If correct, where does that conduit terminate? I assume people are using this conduit for rewire to add panels. Correct? The factory tech rep indicated the existing wiring will tolerate 530 watts only, which means a rewire for panels of greater total wattage. Exactly where that conduits goes would be helpful to know.
