I'm trying to model PV for a home with a crawlspace foundation, but the optimization algorithm keeps ignoring all PV options I've listed. I created a second case to test what would happen if I mandated PV without an option for no PV, and the simulation failed immediately and produced the following errors. Is this a bug? PV options have been considered for other models I've simulated, the only notable difference being the foundation type. See model here
