The satellites and Earth travel at the same rate of speed and thus stay in the same position in relation to one another.
More serious results occur when a satellite antenna has been painted with metallic or highly reflective paint.
The actual part of the world undergoing solar outages at any time of the year is directly related to the latitude which is directly in line with the satellite and sun. For 9.8 feet earth station, outage season lasts for a little over a week and during this time, there will be an outage on each satellite, once a day. The outage appears first as a bit of video noise, rapidly becoming annoying interference and on the days at the center of the outage season, peaking out as total loss of incoming signal. They occur every spring, and fall, as the sun (in transit from winter's low perspectives, to summer's high ones) lines up directly behind the satellites, from your point of view.
The exact dates change slightly, from year to year, with the dates of each solar equinox; and, every year are earlier in the spring (and later in the fall), at greater latitudes, than at lesser latitudes.
The "few minute" variations are deemed tollerable, for the purpose of recognizing that "Sun Outage" is indeed what is happening to existing ystems. Big dishes, and their Linearaly Polarized Analog Signals, are temporarly "wiped out" by the sun's being behind their Satellites.
Satellite solar outages occur because the sun which is a powerful broadband microwave noise source passes directly behind the satellite (when viewed from Earth) and the receiver with the beam directed towards the satellite picks up both the satellite signal and the noise from the Sun.
The degree of interference caused by a satellite solar outage varies from slight signal degradation to complete loss of signal as the downlink is swamped by the noise from the Sun. For geostationary satellites, the solar outage can typically cause disruption to the received signal for a few minutes each day for a few days. Parameters such as the antenna directivity can make large differences to the amount of time of the solar outage.
It is found that the in the Northern Hemisphere, solar outages usually occur in early March and October as a result of the geometry and relative positions of satellites and the solar transit of the Sun.
The exact dates and times of the solar outages are easy to predict and many calculators are available. This is a three hour time-lapse video on March 4, 2009 taken at the satellite earth station of Full Channel TV, Inc. The shadow of the dish's feed horn can be seen passing perfectly under the center of the dish. Twice a year, in the spring and the fall the sun passes across the equator directly behind each geo-stationary satellite in the Clark belt. While satellite solar outages, or satellite sun outages can be annoying, they are normally short lived and they are totally predictable. You cannot block the RF noise from the sun without blocking the signal from satellite, so everyone will experience loss of signal during a solar outage.
To calculate the date and time of solar outages you need to know your latitude and longitude, the longitudinal position of the satellite, the receive frequency and the diameter of your dish.
What will happen to your grid-tied solar photovoltaic system if a power outage strikes your area? Many solar panel systems do not work if the utility grid is down, but most can be set up to do so. Grid-tied solar power systems are less expensive than their off-the-grid counterparts, as they require fewer components. The downside is that, when the utility grid goes down, so does the electricity in your home — even if the sun is shining brightly. Actually, that’s the problem — if your system weren’t powered off, your panels would continue to produce energy. Utility workers are sent out to repair the damaged electrical lines, transformers and other components. For that reason, your system cannot continue to produce electricity when there is a blackout. You could add a battery bank to your array to store power produced by your solar panels, or you could choose to invest in a gas-powered generator.

160 watt-hours per day would be 6 hours sun, which is probably about right for here, in summer.
Is it okay to shop around and find the cheapest 30 watt solar panel, or are cheaper solar panels going to burn out quickly? Would it be smarter to do more research and buy the battery, inverter, and charge controller separately? I would advise you to go and talk to someone who builds and sells these systems, and not buy the parts at wal-mart. If you go down the buy-it-yourself route, keep in mind that next to a charge controller you'll also need a maximum power point tracker. If we bought an external charge controller and a 50 watt solar panel, would the larger panel charge our power pack faster? Please let me know what you guys decide, I would love to know what you decide on and how it works for you.
So Roland confirms something I thought but was not 100% sure about (converting amps and volts to watts always trips me up mentally): The battery in that "600 watt" power pack does not provide 600 watt hours of output. In my 2006 Backwoods Solar catalog, prices for a full system start at $800 (for a 65 watt panel, a couple batteries and controller) and go way up. Take the total watt-hours you need per day, and divide by 6 (for 6 hours sunlight) to get the number of rated watts of solar panels you will need. Add 50% more watts to deal with "solar panel derating" (ie, panels only produce their rated numbers in ideal conditions) and power conversion loss. The numbers I've heard for solar panel degradation over time is they might lose 10% over 10 to 20 years. Anna -- According to a local supplier in the Netherlands, a 100 Wp (Watt peak power) panel would cost around a‚¬ 300 and generate around 80kWh per year.
You should also consider using an inverter to generate AC and then deliver power back to the net. Astronomers everywhere have been warning about the severe rise in solar flares that is expected for 2013.
However, the bout of solar flares that happened in the 1970s is nothing like what’s expected this year.
The biggest risk that scientists are concerned about is that of electromagnetic pulse (EMP).
That may not sound all that serious, but you have to realize that the entire infrastructure that we depend upon is controlled by electronics, specifically computers. Imagine living in a world without running water, city sewer service, all of the home electronics that we all depend upon, stores, gas pumps, heating and air conditioning, refrigeration and much more. An EMP attack is probably one of the worst disaster situations possible to prepare for, simply because of how much we depend upon will disappear in a moment. Placing electronics in a Faraday cage is an almost foolproof way of protecting them from the devastation of EMP. That will take care of small electronics, but it won’t help you much with large electronics or electronic devices that you use regularly. Our electrical grid is going to act like a huge antenna for that electromagnetic radiation, capturing it.
Driving a ground rod into the ground next to where you park your car provides you with a simple way of grounding your car at home.
Typically, items that have a motor, such as a refrigerator and HVAC system, will require considerably more power current to start up than while running. There is no sense in investing thousands of $ only to keep the panels buried for after an event that might not occur.
There is a difference between an EMP which is the result of a nuclear explosion in the earths upper atmosphere and a solar flare. The only truly safe Faraday cage is a full ungrounded enclosure with no transmission lines or breaks. I live in longview area I see you are in Texas am I close enough to you that I could join your prepper group?? At almost any builders supply, there is very inexpensive insulating material that is a 4×8 sheet of hard foam with a layer of aluminum foil on one side. Bonnie, I was actually pondering a modified trash can that would be aesthetically pleasing in my home. Ben, we live in two old mobile homes joined by a wide hallway that both have the aluminum siding on them. Guys, I would caution against jumping to too many conclusions about what will, and what won’t be affected by nuclear and CME EMPs.
If you have a 1250 watt goal zero yeti solar generator with 4 solar panels at 30 watts each, would I have to worry about that also?


Question: Could a walk-in cooler structure with aluminum walls, floor, ceiling and door serve as a Faraday Cage?
These guys quickly placed the large bit of metal on their vehicle and scampered in to the night with it. It’s unfortunate that it didn’t happen before the Nepal earthquake, lives could have been saved.
If it’s not the Nepal earthquake near Kathmandu and Patna, it’s the cloudburst in Uttarakhand, or landslide in the Kashmir valley, or draught in Vidarbha, or hurricane in the US, or Tsunami in the south-east of Asia.
In Nepal for eg, hundreds of victims of the recent earthquake may have been saved, if electricity was not disrupted due to the falling towers and if power was locally generated and available even a bit. The loss of life and economy from the Nepal earthquake can barely be estimated, even so only, once the emergency relief work starts its slow withdrawal and life starts to get some resemblance to normalcy. The more distributed power generating systems there are, the less impact such disasters can have and the more loss of live and livelihood can be prevented.
As eminent solar champion Jigar Shah tweeted the role of solar power and by corollary distributed solar is now clear as inevitable if we are to be better prepared.
Popular Mechanics has identified solar power systems as a top life saving tool available for disaster management teams during and after such natural calamities. However in a calamity like the Nepal earthquake where road access itself is cut off even this will be rendered ineffective when really required. Even if part of the solar power system is damaged, the remainder can be quickly and easily be reassembled, hooked back up to provide power almost immediately, thus providing basic electricity, communication, water filtration etc. Given the same transmission and distribution system required, even centralized solar farms are no help, since they are equally vulnerable to such calamities. While it is critical that the proven solar power concept is aggressively championed and deployed on a war footing, it is unlikely that we will let go of the old anytime soon.
Leapfrogging a tech cycle like in Telecom, where instead of spending billions to make landline telephone access to everyone we skipped straight to cell phones is possible with proven solar PV technology.
The time to champion the cause is now, not in the next few days when the world stars to get distracted by other events and we leave the memories of this disaster behind. Satellite antennas are designed to collect radio frequency and concentrate it at a prime focus point, where the energy can be detected and amplified. Besides the physically familiar light, and heat, are strong microwaves in all the frequency bands of our satellites. Larger dishes, and those with better parabolic shape, enjoy better focus, and are "hit" for fewer days, and fewer minutes on their worst days. More precise data can be calculated, for your specific location, as are sometimes used in diagnosis as to the orientation, and condition, of commercial dishes.
The reflectively concentrated solar heat, at these times of solar transit, can damage the feed, and electronics (LNBs, Servo, etc).
Antennas with a very wide beamwidth could be affected for as much as half an hour, whereas antennas with higher gain and directivity levels as are more commonly used for satellite reception will be affected for much shorter periods of time.
Even at times of low solar activity, the effect is very noticeable and can result in noise levels of between 10 and 20 dB above the signals from transponders, dependent upon a host of factors.
The solar outage angle of the antenna angle is defined as the separation angle (measured from the ground station antenna) between the satellite and the Sun at the time when sun outage or signal degradation begins or ends. All that is needed is a knowledge of the satellite position (sometimes just the satellite is needed as its coordinates may be held within the calculator), the position of the receiver in latitude and longitude.
This biannual occurrence happens around the equinoxes and causes what is known as sun-fade or sun-outage.
When the main beam of the satellite dish is in direct line of sight with the sun, a sun outage occurs.
On the days before and after when the sun is directly aligned with that satellite there will be less outage.
They affect all satellites, and in particular these solar outages are commonly experienced as a result of the widespread use of satellite direct broadcast TV reception.
But you can block the visible sunrays by putting a non-transparent plastic bag over the LNB or dish without blocking satellite signal.
Let’s take a look at what you can do to ensure that your home always has access to electrical power. Connecting your PV array to the grid gives you a reliable source of electricity at night and on cloudy days, when the photovoltaic panels are not as efficient. But because that’s not safe, your system automatically goes down whenever the utility grid does.
When you’re connected to the grid, excess energy flows back for use by other utility customers. If your solar panels sent excess energy through the lines while the utility crew was attempting to fix the problem, someone could be seriously hurt. This type of hybrid solar power system allows grid-tied solar panels to provide a limited amount of daytime power, giving the customer some electricity without sending any back to the grid.
They can probably give you a good advice on what & how much you need given your power requirements. I'd like some more detail in this area as I will soon be using a decade old 256 watt PV array. But with the capacity of 12 V x 28 Ah = 336 Wh, pulling 600 W from the battery would deplete it in about half an hour!
Even NASA has issued warnings for this, concerned that they could cause major disruptions on a worldwide basis. Often, this is broadband radiation, which hits our atmosphere and causes problems with radio reception.
The solar storm of 2013 should be a couple of orders of magnitude greater than that of the 1970s. This is the same sort of radiation that occurs when a nuclear bomb is exploded above the atmosphere.
Other than military electronics, very few pieces of electronic equipment are designed with the necessary protection to prevent EMP damage. This is already the most sensitive portion of our infrastructure, with much of it being outdated and in need of repair. This is based upon two things: the fact that metals are great conductors of electricity and that electromagnetic waves are attracted to metal. All you need is an enclosed metal container, such as a portable metal file box or a metal trash can. You can protect those to some extent by a combination of using surge protectors and grounding them. Simply use a jumper cable, connecting it to any accessible part of the frame (bumper supports are accessible and might work) to the ground rod.
Best practice, when preparing to put a generator on-line, turn off ALL circuit breakers before turning on the auxiliary power generator, than only turn on one breaker at a time that controls those high start up appliances before turning on others, such as lights and outlet receptacles.
A solar flare can cause damage to devices connected to power lines or long lengths of cable(hundreds of feet). Things like battery operated radios without the batteries installed, spare parts for off grid power generation like controllers and inverters, spare car parts if you have a car that’s post 1985. Think of the gaps in the viewing window of your microwave as the largest possible gap for an effective faraday cage. I assume it’s not entirely necessary to attach a copper grounding wire to the can for it to be adequately grounded in the event of an EMP strike? Its small, 9x9x9, the inside is completely press board, inside I have a small water pump, inverter, some flashlights and a couple cooling fans.
Experience shows that the first essential service to be impacted in most calamities, natural or otherwise is the power grid and the electric supply.
In a distributed system there is no single point of failure that can bring down the whole system, as there is with centralized power generation. If solar power is generated at any given location the need for towing in a relief solution, which itself poses a logistical problem (given that often roads are unplayable during such calamities) won’t arise. This power then had to be transmitted over really long cables with transmission sub-station and distribution transformers and whole paraphernalia of expensive equipment before it’s of any use to the end consumer. Solar PV technology has be available for decades to simply generate power where needed, making the old “essential equipment” largely redundant.
This type of a solution needs no additional infrastructure and can be critical in disaster relief. A better and more resilient solution is to shift focus, to distributed captive solar now, so that democratic electricity is a life saving reality. Instead of large scale investment in centralized power generation capacity and upgrading T&D, skip straight to localized distributed generation. Can we afford any loss of life because we never question the answers provided to our electricity problems?
There are times when the sun passes behind a satellite that an earth station is receiving from. Outages in February, March and April begin at the northernmost latitudes, moving southward until stations on the equator have outages at the time of the equinox. The outage angle is defined as the separation angle (measured from the ground station antenna) between the satellite and the Sun at the time when sun outage or signal degradation begins or ends (see diagram).


In addition to this there are many differences between different installations and systems. At these times of year the Sun crosses the equator and it traces an arc that places it directly behind geostationary satellites. The time of day varies mainly with the longitude of the satellite and receiving station, while the exact days vary mainly with the station's latitude. The beamwidth of the antenna is often needed as it will enable the time of the satellite solar outage to be determined. The actual days and times depend on your latitude and longitude, longitudinal position of the satellite, diameter of the dish and the received frequency.
However all satellites are affected, whether geostationary or in other orbits, and the effects can cause short lived disruption to the radio communications. Normally a LNB can cope with this, but in exceptional cases (a wet, shiny dish surface and bright, sunny weather), the plastic cap covering your LNB can burst! Alternatively you could swing the dish out of position during a sun outage to prevent damage to the LNB.
There is a troubling nearby patch over most of Tennessee (excluding the NE tip) where they suggest adding 60%. I don't know what your local regulations are and what price you'd get for your generated energy, but it might be worthwhile to find out. Part of the problem is that we’re really not sure what kinds of effects the solar flares are going to cause or how serious those effects will be. Back in the 1970s, this was severe enough to put an end to the CB radio craze, essentially eliminating all but the shortest-range communications on the frequencies that CB radios use. Since the lack of an atmosphere prevents the energy from going out as a physical shock wave, it goes out as electromagnetic energy. So, there’s a strong possibility that a large portion of the commercial and consumer electronics that we depend on for our day-to-day lives would be out of commission. People will have to do everything for themselves, from filtering their own water to growing their own food. You can line the container with any of a number of materials, but one that works extremely well is sheets of Styrofoam. In fact, that spike is probably what will ruin most home electronics, rather than the EMP itself. Another way is to use an AB switch; one side connects to the grid and the other connects to your generator.
Do you think it would be feasible to enclose the rest of it with metal screen and have an effective “faraday garage”? I would put spare Charge Controller and Inverter in a Faraday Cage along with a couple small panels to recharge batteries of all sizes. An EMP causes damage to all electronics due to the high voltage that falls to earth like an umbrella from the point of explosion. Hopefully these guys are making absolutely certain no part of the ground is above ground or they just turned the cage into a ridiculous antenna.
Since we did the new roofs, our cell phone doesn’t want to work in the house very good anymore.
It probably is a violation of the electrical codes for buildings in your area, wherever you are. After all, Earthquakes don’t strike twice…except they do, and natural calamities come in various forms.
Because of the nature of the beast, the electricity transmission and distribution power grid is the one most susceptible to any of the calamities listed above along with being the prime target for hacking, terrorism and other man-made disasters. In 2001, virtually all of northern India was blacked out, after the failure of a substation, triggered the collapse of the country’s northern grid. A distributed solar power system may be simply on an empty rooftop or at a nearby location from where power can be sourced in case of emergencies.
Thinking “Small and Distributed”, when “Large and Concentrated” has been the norm takes a radical shift from convention. When this happens, the satellite's signal is obliterated by the tremendous energy of the sun. When this energy is reflected in a satellite antenna, temperatures can reach thousands od degrees within a few minutes, even on cold days.
The "occurance", on such a dish, will be momentary, at the beginning and ending dates; and last about six (6) minutes, on the worst day. Accordingly some stations may experience a complete loss of signal while others may only experience a tolerable degradation of signal. Stations along the equator will experience solar transit right at the equinoxes, because the satellites in geostationary orbit are located directly over them. The larger the dish diameter and higher the frequency, the shorter time and the fewer days sun outages last.
This will probably not occur very often or long, depending on at what angle and orientation you fix the panels, and how sunny it is. In addition, it affected commercial radio and television transmissions, sometimes severe enough to block out reception in outlying areas. Since the sun (or any star) is essentially the same as a sustained nuclear explosion or hydrogen bomb, it produces large quantities of electromagnetic energy as well, especially during times of solar flares. This is usually accomplished through a copper-plated rod, installed through the foundation, right below the electrical box (it’s usually hidden in the wall).
The AB switch can have an center OFF position so that your loads are not connected to either source of power. Essential services, businesses, transport and essential supplies ground to a halt, affecting 250 million people and causing 107.1 million dollars loss to business in just 12 hours. Such an enterprise would not have been possible with traditional resources of power generation like coal or gas plants. Not to mention the control that the few will lose over the newly independent and mostly self reliant electricity consumer.
The home TVRO owner will lose partial or complete reception from his system for approximately 10 minutes. In August, September and October, the entire pattern is reversed since the sun is moving in the opposite direction. In view of this it is not possible to exactly determine the exact solar outage angles without complete information about the ground station equipment and the satellite parameters.
Basically, the satellite signal is overwhelmed by the unwanted signal from the sun; the signal from the sun is what we call noise. Secondly, the electronic devices inside must be fully insulated from any physical or electrical contact with the faraday cage itself.
The surge protectors themselves may not survive, but they will protect the equipment connected to them.
You can connect specific loads directly to your generator with dedicated line cords; proper AWG to fit the load. The solar flare lasts for seconds to tens of seconds while the EMP lasts for les than a second. Grounded from the side to a stake that goes 3 feet in the dirt, and, the entire rig (except the ground and wire) are wrapped tightly in a mylar bag. The United States government actually built an underground bunker lined with lead once and it generated so much current that it was unusable. Especially in winter when irradiation is low, you might need several days to recharge the batteries.
If you have a room with a lot of electronics in it, such as a home office, adding an additional ground would be advisable. I wanted to azdd a bit of extra protection, so i stacked a tire on top of it, the box fit perfectly inside. I’ve wondered what would happen if I put aluminum foil on the inside of the windows (I *do* do this in the summer on some windows just to reflect heat). They also occur in cloudy weather, as the RF radiated by the sun is only dampened slightly by clouds.
Also, we have a new steel storm shelter that we are putting in the ground next to our trailers – would it be a good place to put some spare electronics?
Wrapped the whole Faraday tire stack in a plastic garbage bag to protect it from the rain but I dont think it was really needed in the first place.
My husband is wanting to put foam insulation on the sides of the shelter down in the ground for some reason (to cut down on condensation inside??).
I’m not crazy about it just because the foam has chemicals in it and it would be in the ground where they could leach into the ground water. We are also planning on building a wood shed over the shelter (so we can get in it without being out in the rain) – if we lined the inside of the shed with foil insulation (mylar bags?), would that also help to keep *whatever* is in the shelter below from getting hit?
