Understanding the probability of an EMP of sufficient field strength, during your lifetime, is sufficient to warrant action on your part to protect your devices and solar panels from it.
There are differences in effect and magnitude between nuclear high-altitude EMP (NHEMP, or EMP caused by a nuclear weapon detonated high above the earth), geomagnetically induced EMP (GIEMP or EMP caused by solar weather), and nuclear low-altitude EMP (NLEMP or EMP from a nuclear weapon detonated near the ground). NHEMP is not a single EMP pulse, but rather, it a pulse consisting of three separate components: E1, E2 and E3. Since most DIY Faraday cages are either too bulky, too heavy or too delicate to travel with you in your rucksack or backpack, another solution is needed to protect portable solar arrays, portable solar chargers and other portable solar gear in your pack.
Since an NHEMP could produce almost double the field strength that 40dB of shielding will protect, take the added precaution of sealing your solar panels inside two layers of bags which each provide at least 40dB of shielding. Lastly, make sure that the bags that you choose have a non-conductive inner layer just like needs to be installed in a Faraday cage to prevent electricity from arcing from the conductive layer(s) of the bag into the solar gear that you are trying to protect. EMP caused by nuclear weapons has three different types of effects that need to protected against. Solar panel & electronics stored in inexpensive shielding solutions such as Faraday cages and Faraday bags are only protected from E1 & E2 while they are inside their shielded storage containers! And you know the principles involved in building an effective Faraday cage, what to look for in Faraday bags and that one layer of most of the bags on the market today is insufficient to protect against EMP. Now you now know the basics of protecting your stored and portable solar gear against EMP in ways that almost anyone can afford! Watch for the second part of this article HERE to learn the principles involved in protecting grid-connected solar installations like you may have mounted to your rooftop or near your home. He is a talented competitive shooter, has a profound love of nature, and likes to backpack, camp, hunt and pursue outdoor hobbies. Part II of the article will be published tomorrow and it goes into more detail specifically about protecting a structure and its contents. Yes, whether your solar panels are mounted on the exterior of your vehicle or carried inside, they would be vulnerable to EMP unless you take steps to protect them. Yes, I know for a fact that 1 mil thick aluminum foil provides enough shielding to protect against EMP of up to 50 thousand volts per meter. The amplitude, frequency and polarity of the wave(s) which impinge upon your equipment will be the determining factors in estimating the damage which will ensue from an EMP.
Since we don't know the frequencies involved in a potential EMP threat we must design for a worst case scenario. An expensive way to proceed is to NOT shield the system and allow it to operate until (and if) an EMP strike occurs. We already have the technology available to us to protect the grid and homes from EMP, but it cost's more money, so a utility company that implements it won't be able to compete with a company that doesn't.


If you want to know more about what you can do to make that happen, sign up for the newsletter at EMPActAmerica.org to learn more about EMP, advances that our enemies are making in the field and when legislation is being proposed.
This is the potentially cataclysmic threat that EMP poses, and the reason to plan your survival. Gamma rays interact with the earth’s magnetic field causing it to re-radiate a powerful EMP and scatter high energy electrons, creating a thousand times the EMP that the same weapon would cause in a lower-altitude burst. Much of its effect on the grid would be protected against by lightening protection, if the lightening protection circuits were not already burnt out by E1 when E2 arrives. That’s because the nuclear weapon detonates too low to cause the earth’s magnetic field to re-radiate EMP.
Just protect them against NHEMP, since it packs all three components and is the most powerful type of EMP. Because of the large frequency range we must protect against a hole as small as a ? inch could compromise the integrity of the Faraday cage for our purpose. Make sure to find out the strength of the shielding in the bags before you make a purchase.
Most bags are designed to protect sensitive semiconductor products from electrostatic discharge or to hide your passport and credit information from would be identity thieves so the most shielding currently offered in a bag is a little over 40dB.
You may not be far enough away from “sky zero” for the field strength of the EMP to weaken enough that your panels will be safe. He is profoundly grateful to his mentors for afflicting him with an insatiable curiosity about all things self-reliant but claims to be allergic to conspiracy theory. Part II of this article, which will be released tomorrow, will talk about what is involved in protecting larger volumes and installed panels.
Part II of this article will be published tomorrow and it's about the principles of protecting installed solar arrays and larger spaces so be sure to check back.
If only a small percentage of our largest transformers are knocked out it would take 3-4 years to get the power back since no protocol even exists to "cold start" modern power plants. It is my understanding that the powers that be were told of maybe an impending EMP attack on America, And I am wondering if the power companys and the government have been work on a way to secure our power plants and sub stations, In my town there is a big power generation plant, and crews have been working on it for 2 years now nonstop, But as always secure your own gear people.
It happens so fast (1-2 nanoseconds) that surge protection used in the power grid can’t clamp fast enough to stop it and will be disabled by it. To protect portable solar equipment carried in my backpack, I use lightweight bags marketed as Faraday bags to shield them. But just Compton scattering was once new to us, we are constantly learning about new properties of EM energy. Your vehicle should be made as EMP-resistant as possible, which would be a good topic for another article (or an entire book), but I'd be happy to give you some pointers on what's involved in protecting your vehicle once you've read Part II of this article since it talks about shielding larger volumes and installed panels, so be sure to ask again after you've read part II so I can address them both together.


Although surge protection with fast enough clamping times exists, it is not typically used since it’s more expensive and more commonly occurring surges are much slower than E1. The level of difficulty of protecting the shed's contents would increase if it is connected to outside power.
A couple of years back we learned about new threats to spacecraft from "killer electrons." I think the important thing to take away is that the USSR was ahead of us in EMP research when we signed the high altitude test ban and most of what we think we know is largely theoretical.
Maybe we could even talk the editor into publishing a part III covering vehicles or a companion article to an existing Survivopedia article on protecting autos from EMP. Faraday cages protect their contents from external electrical fields but magnetic fields penetrate them, and that's fine. For a cage protecting an entire building, for instance, a proper ground is strongly recommended.
EMP damages electronics by inducing high voltages in them as opposed to exposing them to a magnetic field.
Quantifiable standards must be established and used to properly qualify the claims of products and so on. So a Faraday bag can protect electronic contents from electrostatic discharge or EMP, yet you can't stick magnets to them. As must be the philosophy of Faraday bag manufacturers, since they don't seem to make products with more than about 40dB shielding, if you aren't right under a nuclear EMP you could get by with less shielding since some shielding is definitely better than no shielding and not every single device will be damaged. They only came online within the last few years because of the congressional investigations into the EMP threat. Tests at NASA show up to 49 dB of protection (Average 45 dB) but don't know if the batteries also need to be protected. So does whether or not the battery is installed in a device, the length of conductors in the device, it's conductivity, whether or not it is connected to the grid or other long conductors, whether or not the device is turned on, whether or not the device has fuses (and the properties of the fuses), the field strength of the EMP, the distance of the EMP, whether there is any shielding between the battery and the EMP, even the orientation of the battery and the shape of the earth's magnetic field lines between the battery and the source of the EMP will factor in. I think that where the shielding could fall apart is if someone has developed a super-EMP weapon capable of generating EMPs of higher field strengths.
Soviet high altitude nuclear testing in Kazakhstan in 1962 damaged very simple diesel generators that lacked any electronics whatsoever, and those tests only yielded 10-20% of the EMP field strength that we are trying to protect against.
So, I hope that if you read somewhere online that small batteries won't be affected by EMP, you will know better. Even if EMP wasn't a factor, I would still carry my batteries in organizers so they wouldn't short out on each other or other conductive gear.
