Lightning can strike rubber although it is not a good conductor of electricity.
I understand the PV boys having problems with RCD tripping from the leakage current from the inverters are substituting the 30mA RCDs for a 100mA type or a time delayed RCD thus destroying the 30mA RCD shock protection.owever if the rcd protecting the circuits (of which the PV circuit is one) is double pole then once it cuts off then as neither phase nor neutral of the inverter output is connected to or referenced to earth then touching either live conductor should not present a shock risk unless there is a second fault.
