The good news is solar panels in and of themselves contain very little electronics that could be affected by an emp.
Would emp damage solar panels.
Photovoltaic pv solar panels battery banks and all other components of an off grid solar power system would not be affected by an emp directly as they have no circuitry within.
But if damage occurs it is likely due to the wires between the solar panel and most often the solar charge controller.
Whether a nuclear bomb or a solar event causes an emp the cost is enormous.
However the larger the solar array is the more likely that there will be damage to the supporting equipment including the wiring charge controller and inverter.
The majority of solar panels would probably not be damaged.
The bad news is they re usually connected to wires with current flowing through them which makes them susceptible to damage.
They do suffer some damage reducing their output by about five percent but they will still work.
Because of a multitude of factors that would affect solar panels during an emp such as the magnitude of the emp event it s difficult to say for sure what kind of protection is needed to completely protect electronics from the its effects.
A solar panel itself may be inherently resistant to emp to some extent.
But since solar panels are pretty expensive i guess that only a few people buy them just to put them aside for hard times.
But a nuclear emp powerful enough will destroy unprotected solar panels.
Surprisingly enough solar panels can weather an emp fairly well.
This means you won t be able to use your solar panels.
Emps can irreversibly damage anything with a circuit in it including your solar power system inverters and charge controllers.
Would solar panels survive an emp attack.
The good news is that almost all other components of your off grid solar setup would be unaffected by the emp.
What we do know is that emps are caused by both nuclear explosions and by the sun i e.
The best way to protect them is of course to enclose them in a faraday cage.
The larger your solar array the more likely is that an emp will damage other equipment associated with your solar rig like your inverter wiring and charge controller.
The different parts of a nuclear emp.
The other cause of a widespread emp disaster is from detonating a nuclear bomb.
However an emp would likely damage the connecting wires through which the current flows.
