For common setups, plan for a total of about $1,000 to $3,300. A minimal upgrade in a straightforward home with nearby access and no trenching might land near the low end, while complex sites with long runs, concrete restoration, or permit requirements push toward the high end.
Solar panels can be disconnected by shutting off AC and DC disconnect switches, covering panels with opaque material, verifying zero voltage with a tester, unplugging MC4 connectors, and removing mounting hardware.
Article 690 of the NEC mandates that #8 AWG or #6 AWG are the smallest wires that can be used with grid tied solar panels and inverter systems, and for solar panel output circuits, #10 or #12 AWG are allowed. A ground rod is also recommended if the installation area is prone to.
