The limits of this have not been tested -- low-voltage wiring would be exempt (NEC 70), and a gravity-fed catchment might also be exempt.
So, not to get too confident, photovoltaic (solar) systems are not low voltage if you have an inverter.
If you have panels to a battery, and the battery provides the DC current to the 12 VDC appliance, then it is exempt. If you have panels to an inverter that supplies 110VAC to the appliance, an electrical permit is required.
Also note that DC current is no different than AC current in the fact that it can, and will shock, if nor electrocute you.
