Solar Lightning and Lightning Protection

The frames and mounts on panels are usually grounded (sometimes more by accident than design), and that often diverts the lightning directly to ground, saving the panels. Also, the battery banks on most off-grid PV systems act as a fairly good surge arrestor if you have good connections and a good ground - but it may take out the controller on it''s way.
