1. I don’t disagree with this but when you install a ground electrode at your array you are complying with this.Do as you wish but it wouldn't pass inspection or be safe.
690.43 Equipment Grounding and Bonding
Exposed noncurrent-carrying metal parts of PV module frames, electrical equipment, and conductor enclosures of PV systems shall be connected to an equipment grounding conductor in accordance with 250.134 or 250.136, regardless of voltage. Equipment grounding conductors and devices shall comply with 690.43(A) through (D).
You stated this requirement was not in NEC 2020 but Mike Holt's video indicates otherwise.
2. The Neutral coming in from the grid is grounded at the substation, and every pole with a transformer and every guide wire to a pole. This is what I meant when I said you get a ground from the grid.
