Aaron, An exterior utility service panel with an underground service lateral is not considered in or on the building.
Keep the dc conductors off of the building and you will be fine with a ground-mounted PV system. Don't bring them inside the building, and don't run them along the exterior of the building. The whole requirement is to deenergize conductors that a firefighter might come in contact with while fighting a fire. The most important conductors are those inside the building. A PV array on top of a buiding is also required to deenergize the conductors within 10 feet of the array (PV Output Circuit Conductors). The array is allowed to remain at full voltage.

When looking at the rapid shutdown language, does PV systems "on" a building refer to only situations where the array is on a building; or does it include DC conductors as well. For example, if the DC conductors from a pole mounted array run up the side of a building before punching in to the inverter, does this require rapid shutdown? Is this PV system considered "on" a building?
