Why is solar more expensive in the U.S. than in other countries?

Does this basically mean that the only real piece of equipment that needs to be rock solid is the transfer switch, and not necessarily the whole system consisting of panels, batteries and inverters (for grid tied systems)?

You could mislabel lines that stay live after grid disconnect as though they were on the grid side of the cutoff switch.

Making truely idiot-proof high voltage wiring is difficult. However, that's what inspectors are for (in theory).

Also, solar panels are heavy and pointy and often stored on roofs where the wind can grab them. Again, inspectors should check this.

For safety, yes. For performance, no. Cheap Chinese inverters can create all sorts of nasty effects on the local distribution segment, but IMO performance requirements should be up to local distribution utilities when they allow the interconnect, not a matter of national concern.
