How To Limit Exposure To Emr
Lets say Ive failed to convince you that your solar system is likely to expose you to less EMR than other electrical devices in your house and you want to take precautions. Well dont worry. KFC has you covered with their finger licking good Faraday cage:
For just $10,000 US you can install your solar inverter in the Colonels internet proof enclosure where he will watch over it, unsleeping, for eternity. Of course, if you want to monitor your inverter performance online, youll have to open the door.
This chicken coop for humans works by blocking EMR from getting in or out. If you look carefully youll see its walls are made of metal mesh and if you look at the door of your microwave oven youll see there is also metal mesh on that4. Microwaves and longer wavelength EMR simply cannot fit through the small holes and so are blocked.
Of course, its not actually necessary to pay for a $10,000 Slenderman killing enclosure. You can use a metal cabinet or any fine mesh. Using mesh with holes wide enough to let your inverter internet connection work but small enough to block longer wavelengths is an option. But whatever you use, you will have to make sure it is adequately ventilated so your inverter doesnt overheat.

How Is Solar Energy Harnessed By Solar Panels And Solar Farms
You have likely seen a type of solar technology called photovoltaic technology. It is used in the solar panels that you see on the roofs of homes or businesses, or as part of larger solar farms. As the sun emits solar radiation, PV technology uses cells to absorb that radiation and turn it into electricity. That electricity can then be stored in batteries or fed back to the power grid.
Another type of solar technology called concentrating solar-thermal power uses mirrors to reflect solar radiation and convert it to electricity. CSP is mainly used in large power plants.
Silicon Valley Toxics Coalition
Many panel manufacturers are focusing on sustainability in the manufacturing process to promote the health of the earth, as well as employees and factory workers involved in the production of their panels. A nonprofit organization known as the Silicon Valley Toxics Coalition is leading the pack in advocating for sustainable practices for electronics manufacturers, including solar panel companies. They publish a report known as the Solar Scorecard that evaluates a variety of panel manufacturers on their environmental protection measures, as well as measures for their employees and their communities.
The scorecard uses a few different factors to determine manufacturer ranking on the Solar Scorecard, including emissions tracking, how many toxic materials are included in their modules, water usage in manufacturing, the use of conflict materials , and workers rights.
In the most recent Scorecard, SunPower was given the highest ranking of the companies that responded to the survey, followed closely by SolarWorld, Trina, Aleo, and Jinko.

The Problem With Solar Panel Disposal
Most solar recycling plants simply remove the valuable silver and copper from the cells and then recycle the contaminated glass and plastic casing by burning them in cement ovens. Since the process is costly and time-consuming, its more convenient for solar companies to drop the dead panels into landfills or export them to third-world countries.
While a properly-built landfill should contain most hazardous material in the waste, a developing country may not have the infrastructure or regulations to properly dispose of imported solar panel waste. Potential leaching of these metals into the surrounding environment can pose a public health problem, especially in a nation without the necessary disposal infrastructure. As society continues to adopt solar power, this problem may worsen in the coming decades, with almost 80 million tons of solar waste projected by 2050.
Studies have shown the heavy metals in solar panels namely lead and cadmium can leach out of the cells and get into groundwater, as well as affect plants. These metals also have a record for detrimental effects on human health. Lead is commonly known to impair brain development in children, and cadmium is a carcinogen.

Potential Dangers Of Solar Panels
Like any other modern-day electronic appliance, solar panels are also prone to system failures. Solar panels or modules generally have a lower voltage, leading to the idea of a safer option however, the lowest voltage believed to have caused an individuals death is around 60 volts.
Therefore, lets quickly go through the possible dangers of solar panels and discuss them in detail:
Tap Into The Sunlight
Solar cells, found on solar panels, consist of semiconductor material that causes electrons to break from their atoms and flow as electricity when sunlight hits the material. You’ll find solar panels on calculators, rooftops and even on the International Space Station. Home owners and businesses who wish to use solar energy can install solar panels on their roofs. Some utility companies offer business customers the option to add solar panels to their roofs.

New Report Sheds Light On Health And Safety Considerations With Solar Photovoltaic Technologies On The Market
Many people have asked me lately, “What goes inside solar panels and does any of it pose a health risk?” A report released today by the corporate watchdog group, As You Sow , titled, Clean & Green: Best Practices in Photovoltaics, gives a fair and comprehensive overview of the health and safety risks with regard to solar photovoltaic manufacturing and end of life management. The report discusses:
. . . in non-scientific language, the process of manufacturing PV panels, the risks involved, and how companies mitigate those risks. It focuses on practices and policies companies use to mitigate risks from hazardous compounds, reduce environmental impact, and responsibly manage their supply chains.
Through an exhaustive and comprehensive sampling of some of the world’s largest solar panel manufacturers, the results of the study were impressive especially when one accounts for the sheer size, scope, geographic diversity and highly competitive nature of the global marketplace for solar. According to the report’s author, Amy Galland, Ph.D.:
Close Up Look at Panel Components and Manufacturing ProcessesThe Big Picture
It’s important not to lose sight of the bigger picture. I.e. why solar, especially when applied on rooftop and disturbed landscapes within the built environment, is an environmentally preferable form of energy production. I think the report explains this distinction quite well:
Can The Radiation From Solar Panels Increase Cancer Risk
Electric and magnetic fields together are called electromagnetic fields, or electromagnetic radiation. Imagine these electromagnetic fields on a spectrum, with low-frequency radiation on the low end, which includes things like power lines, and high-frequency radiation on the high end, which includes things like x-rays. Low-frequency radiation is less harmful than high-frequency radiation, which can damage DNA and cells.
Electricity from solar panels and transmission to the power grid emits extremely weak electromagnetic fields. Exposure to low-level electromagnetic fields has been studied extensively, and there is no evidence that it is harmful to human health, according to the World Health Organization . In fact, the WHO notes that most scientists and doctors agree that if any health effects exist from low-level electromagnetic fields, they are likely to be very small compared to other health risks that people face in daily life.
Other agencies, like the European Commission Scientific Committee on Emerging and Newly Identifiable Health Risks, take a more cautious stance. They say that its possible, but far from conclusive, that extremely low-frequency magnetic fields could be carcinogenic, or have the potential to cause cancer, according to a 2015 report. In the same report, the committee notes that studies of magnetic fields generated by roof-mounted solar panels are scarce and that no conclusions can be drawn.

Do Solar Panels Emit Radiation
Modern electronics emit very low levels of electromagnetic fields and radiofrequency radiation. In a photovoltaic system, the solar inverter that converts direct current power from your solar panels into alternating current power is a source of EM and RF radiation.
Neither EM fields or RF radiation pose any health concerns. Heres an explanation of why.
Solar Energy Requires A Lot Of Water
Water is not required for PV cells to work, but for CSP, water is needed for cooling purposes. In fact, CSP plants can use hundreds of gallons of water in the process of converting sun rays into usable energy.
The production of PV cells requires the use of water, as well. That, combined with the energy required to make solar panels themselves, makes them less environmentally friendly to make. It can also have a greater impact on the local environment where the panels are installed.

Solar Panels Pose A Fire Risk
As with other, more conventional sources of electricity, solar panels do have the potential to start fires. The biggest fire risk is usually seen in poorly-installed panels, old units, faulty wiring, or poor insulation. And, because fires caused by PV units are different from traditional electrical fires, there are risks to those putting out the fires, too.
The International Association of Certified Home Inspectors explains that PV systems can be a hazard to firefighters that are not aware they have been installed in a home. They can produce live wires even after the main power has been shut off, can release toxic chemicals in a fire, can prevent access to areas, and even cause roof collapses.
End Of Life And Recycling
End-of-life recycling is also a source of hazardous chemical exposures for workers. Green recycling requires increased material handling and manual separation, which can demand two to three times more individual handing of materials. This can present a risk for strains, sprains, and punctures.
PV end-of-life materials can include lead from electronic circuits, as well as brominated flame retardants , polybrominated biphenyls , and polybrominated diphenylethers used in circuit boards and solar panel inverters. These are considered toxic and potential estrogen disrupters, as PBDEs bioaccumulate in fatty tissues.

Solar Power: The Unexpected Side Effect
The solar amibtions of developing nations look set to deliver more than just electricity. How real are lead poisoning fears?
As the UK lights up its 200th megawatt of solar power, China and India have revealed breathtaking solar ambitions that cast a shadow on the rest of the world. Come 2020, China intends to add 1.6GW of solar capacity while India plans to install a massive 12GW as well as 20 million solar lanterns by 2022. But this wealth of low-carbon renewable energy may have unexpected environmental consequences.
In September last year, US researchers reported that rapid solar power growth in China and India could lead to an unsavoury side effect: lead poisoning. As Professor Chris Cherry from the Department of Civil and Environmental Engineering, Tennessee University, explains, many of these installations will not be connected to the nation’s electricity network, but will rely on lead acid batteries to store excess power. This is where the problems start.
The painful results are well documented. Excessive amounts of lead in the blood can damage the digestive, nervous and reproductive systems, and cause stomach aches, anaemia and convulsions. Growing children are particularly vulnerable with moderate lead exposure causing behaviour problems and brain damage.
Clearly, the rapidly growing motor industry has fuelled these problems but, realistically, how much will a booming solar industry contribute to what is an already burgeoning problem? A lot, believes Cherry.
One Of The More Interesting Questions That People Have About Home Solar Panels Is Whether They Increase Your Cancer Risk This Article Looks At The Science Behind This Question
One of the stranger myths about solar panels is that they cause cancer. The reasons given is that solar panels leak toxins or emit dangerous radiation.
Neither of these are true. Solar panels do not cause cancer. A solar array doesnt emit any more RF radiation than the electrical wires already in your home do. In any case, there is no established connection between non-ionizing RF radiation and cancer. Also, the electricity generated by solar panels is direct current , which doesnt generate electromagnetic fields like AC-carrying wires do. Finally, silicon solar cells, the most common photovoltaic technology in use, doesnt contain any toxic materials.
The only possible way that solar panels might cause cancer is if you ate them. Certain types of thin-film solar cells are made with cadmium telluride and gallium arsenide, which are classified as carcinogens. So, dont eat your solar panel. But home solar panels are almost always made with non-toxic silicon cells.
Health concerns about modern technology are understandable, but renewable energy from wind turbines and solar panels improve our health and environment by reducing emissions from coal burning and natural gas fracking. This article will try to cover the cancer myths about solar panels in detail, and hopefully alleviate concerns you might have.

Disadvantages Of Solar Energy Farm To The Environment
Solar farms sit in extensive tracks of land. The vast tracts of land, mostly in the USAs western states, are home to thousands of wildlife. Insects, birds, and other more giant land animals depend on the desert ecosystem to survive. How inhuman can we humans at times be?
The construction of the Ivanpah solar project located in Mojave Desert, California, faced a lot of criticism. Despite facing criticism from various wildlife conservation agencies, the government proceeded with its construction. As a result, thousands of desert tortoises lost their habitat. Currently, these animals are endangered.
The increasing number of dead birds around the firm has also raised eyebrows. Researchers have attributed the occurrence to the intensive rays that the panels reflect.

Home Solar Power Source
Home solar electrical power generation is completely safe. The electricity produced by your home solar power system is no different than the electricity you get from your utility company. The only difference is the source:
- From your utility company your power comes from a power pole or underground line and is hooked into your home via a breaker box.
- From a home solar system your electricity is produced, in most cases, by roof-top solar panels and tied into the same breaker box.

Solar Panels Are Expensive
Solar panels are not exactly new technology, and there has been a huge increase in the use of solar energy in the last several years. However, the cost of a useful solar panel system is still pretty steep.
Installing a 10kW grid solar system on a residential property can cost up to $35,000, depending on where you live. The average cost nationally in the US to install a solar panel system is about $24,000. The amount of time it takes for solar panels to pay for themselves varies, but it can take up to 20 years.

Can Solar Panels Or Living Near A Solar Farm Cause Cancer
There is no evidence that solar panels are causing cancer, says Noah Kittner, PhD, assistant professor in the department of environmental sciences and engineering at the Gillings School of Global Public Health at the University of North Carolina. In fact, adds Dr. Kittner, solar panels and solar farms may actually be a beneficial strategy to reduce the risk of lung cancer overall. In many cases, theyre offsetting other electricity-generating sources that can contribute to air pollution, which can cause cancer.
Lung cancer is the leading cause of death from cancer, accounting for 25% of cancer deaths, according to the American Cancer Society. Globally, 14% of all lung cancers are attributable to air pollution, according to data reported by Christine Berg, MD, of the National Cancer Institute at the International Association for the Study of Lung Cancer 2021 World Conference on Lung Cancer. And, in 2019, electricity production accounted for 25% of greenhouse gas emissions in the United States, according to the United States Environmental Protection Agency.
