EMP & Solar Energy Systems - What happens?

#1 Post by Andy F » Fri Sep 07, 2018 7:39 pm

Can Solar Flares, Coronal Mass Ejections or EMP Damage Solar Panels or Systems? http://www.sundirected.com/can-solar-fl ... er-system/

The skinny is, they will not damage Solar Panels or Battery Banks since they don't have chip type components within. However, they may or will damage electrically sensitive chips within electronic circuits. My electronics experience is, we are mandated to wear ground straps to prevent stray electrical charges damage to circuits while testing or building.
I do keep certain electronic items in a Faraday Cage.

Think of walking across a carpet during dry winters and then touching a door knob. You get ZAPPED :lol:
The solution for that is touch a metal door key to the knob before you touch it. If it is dark in the room, you can see the little blue-to-white lightning bolt.
I wear a key on a stretchy wrist band during winter.

Unfortunately, SunDirected website above, does not allow me to copy and paste.
If you have sensitive electronics, radios or ham equipment, those are chip circuit type items then you might enjoy reading more in depth there.

Yes, I read all that stuff.

I got to thinking, many would be like me, and need/want a smaller Faraday Cage. I bought the Behrens #6106 locally, like this one via eBay. I think I paid $12.00 a few years ago.
$18.57 + Free Shipping - Behrens #6106 Six Gallon Can Galvanized Metal Pail Locking Lid Handle Pet Food https://tinyurl.com/ybyow4y2

I followed the DIY Faraday Cage instruct from above link at HamPrepper.com

NOTE: You can test it for function by putting a cell phone inside the can and seal as directed, and use another phone to call the number. Mine works as it should.
If you don't have a Faraday Cage, it's been said that a Microwave might work. I've not tried that, yet. I will test that this weekend & tell you what I found out.

I was not sure if this has been shared, please pardon if it has been.
I had it saved in my list of GSM links.

It's a nice Sunday, without sunspots.

Hi all,

Yeah your inverters, control systems, and battery charging systems will be toast. The actual panels I'm not sure about.

But this all depends on the size of the EMP, and where you are located in relation to the magnetic poles.

Will an electromagnetic pulse affect PV solar panels? Last updated on November 4th, 2018 at 12:10 am.
Smaller known CMEs have occurred in 1972 and 1989, and the good news is that photovoltaic solar panels weren’t affected at these times.

If the outside power network is affected by outages such as those experienced by Quebec in Canada in 1989, then your photovoltaic system will automatically shut down to protect itself. Once the power companies engineers have completed their repairs, then it will automatically start-up again.

If a CME were to hit your solar panels, then the inverter that is load-protected and fused would cause your system to shut down automatically. If your inverter was specified correctly, then in most cases, your inverter will be over-specified for your system anyway. The worst case scenario will mean your inverter will blow a fuse and a simple fuse change will get your solar panels back to full working order.

The only way to protect your system is to encase your inverter inside a Faraday cage, but protecting yourself from the indirect effects would be much harder to achieve.

Your photovoltaic panels should be OK, but your definate inverter is at risk. The Faraday cage may help, but even then, fuses will require replacement afterwards.

Even if your solar panels do manage to survive any future EMP attack or solar flare, your other circuit-based technologies around the home will almost certainly not survive.https://www.powermyhome.uk/pv-solar-pan ... lar-panels
