These are the reasons for a solenoid to stop working

Burned out or shorted coil

Broken spring

Overheated spring lost its elasticity

Burned or welded contacts

Dirt in the contacts

The truth is a solar panel could fail if it see's inductive kickback.

The neon will only light when the solenoid is oscilating, so it has to be connected to the source battery. It usually goes out when connected to a charging battery.
