small systems

There has always been much discussion on grounding small systems. For homes on the prairie and in areas with frequent lightning
its good to have a lightning arrester, but they are expensive and not everyone has them. Especially with small 1-2 panel systems.And there is no guarantee of an arrester saving all your gear.
In a home with good wiring /quality appliances etc there is little chance of the ground system actually being in use. But there might be more chance of lightning
hitting a few hundred ft away( monthly) and going up the ground wire towards the controller etc.In a situation like that someone might decide that its better to not connect the ground system.What do you think of that??

    I think they are free to do what they want. It is their money and they will have to add it all up one day. I have never seen this to work as the system grows. If they can afford to grow the system they can afford to protect it. Kind of like any insurance.

    Even with the worlds best protection system, if any part of it gets a direct strike, the locally induced currents will fry most things.  Lightning has such a massive amount of power, it just clears a path for itself for thousands of feet, 5 feet or 20 feet, is not much deterrent.
