The trick with lightning is that it hates to change directions. If it is traveling along a conductor to ground and the conductor changes direction, then lightning will want to jump to the next nearest conductor to ground. In the below picture, the copper power wire (it is insulated) from a windmill is wrapped around a metal pipe that is driven into the ground. The wire is wrapped several times and then loops up and back down again before continuing to the charge controller. It is just clamped to the pipe with a zip tie. Lightning will jump through the power wire's insulator and to the copper/steel pipe and go straight to ground.
