Posted this before post 53. That is true for commercial heavy duty lighting protection on large buildings.
But they don't "attract lightning".
OK I did some fast study. A lightning protection system requires an earth ground. There are different ways to do this. multiple rods driven into the earth is the most common. There are two thoughts on this, ONE; the static is bled into the ground before it builds to a direct heavy strike. Universally accepted by most experts until 50 years ago.. TWO; the strike is directed into the ground by the installed circuits. Presented by some modern experts during the past 50 years. My belief from observation that both are true. There are fewer strikes with grounded systems than with no system.
It is accepted by all; there must be a earth ground, one or more rods driven into the earth. It is also accepted by all, Such system = Will Not Attract Lightning.
It is accepted by code and solar installation experts that solar panel frames must be grounded to an earth ground rod or more. Systems I have examined all have multiple rods tied together with copper wire..
