Do Solar Panels Cause Cancer

Posted 10 months ago by Manual Thomas

In solar panels, solar cells are used to convert light from the sun into electricity

In recent years solar panels have been gaining popularity as a way for homeowners and businesses to save money on their utility bills. 

However, some people question do solar panels cause cancer or not. 

This article will explore this topic in-depth and hopefully give you enough information about solar panel safety to make an informed decision about installing them at your home!

Do Solar Panels On Your Roof Cause Cancer?

Solar panels generate electricity without the need for any fuel, which makes them a green and sustainable way to power homes.

 As solar energy becomes increasingly popular among homeowners, some are concerned about solar panel safety due to possible health risks. 

But do solar panels cause cancer? The answer is no—they don’t increase your risk of getting cancer or make cancer worse.

Solar panels emit no chemicals or toxins of any kind. 

They do not produce carbon dioxide, a greenhouse gas that contributes to climate change and causes acid rain. 

Solar energy is also completely safe for children and pets because it does not rely on the burning of fossil fuels like coal and oil to operate

It also creates electricity in a solar cell by taking advantage of sunlight.

Solar panels have no radiation risk either, which means they don’t cause any damage to DNA or the body’s cells in a way that can lead to cancer or other health problems later on.

So why do some news reports claim solar energy is unsafe? There may be two reasons:

First, solar panels are often put on roofs, which means they can be close to some people’s heads. 

But solar energy does not emit radiation of any kind that could cause cancer or other health problems, it is completely safe for anyone living in the home.

Second, solar panel installation takes place over a short period compared with how long someone lives in a solar home. 

If some people are concerned about the health effects of solar panels, they should consider other sources of energy production that require fuel or chemicals to operate, such as oil and natural gas plants.

Solar Panels Cancer Risk

Let’s explore the solar panel industry in more detail. 

To understand this better, let us look at how these panels are categorized and function to provide you with clean energy for your home or business!

The solar panel is classified into two main categories. 

  • Crystalline silicon cells: They are the most commonly used ones for solar panels. They’re made from rocks and sand, so they’re non-toxic! 

However, some people might say that there is lead in them necessary to wire up your house with.

Well while this may be true at first glance it’s minimal compared to other materials like stainless steel or copper wiring you’ll find on homes today.

Plus those exposed pieces can easily get detached by wind gusts if not securely fastened down yourself. 

The sturdy glass casing ensures no one besides humans ever come into contact with any amount of potentially hazardous material inside these home energy solutions

  • Thin-film panels: They have a completely different technology from silicon ones. 

Instead of using pure silicon to create solar power, there are compounds used that may be toxic but this type is not mostly designed for residential applications.

Some elements can even be found as waste products during mining so it’s safe! 

The good thing about these types of construction compared with standard panel models? 

They’re completely sealed against dust particles and weathering factors making them last longer than expected.

Solar Panels Manufacturing Health & Safety Risks?

The solar panel manufacturing process relies on various chemicals and materials that could potentially be hazardous to workers’ health if not handled properly. Some of the most common health and safety risks associated with solar panel manufacturing include:

Exposure to silicon dust

During the manufacturing process, workers may be exposed to silicon dust and dust from copper, indium, gallium, and selenium. All of which can cause a range of respiratory problems if inhaled.

Exposure to cadmium

Cadmium is used to manufacture solar panels, which is considered an “extremely toxic” chemical by the EPA (Environmental Protection Agency ) and Health Administration (OSHA). Exposure to cadmium can cause cancer and other health problems such as kidney damage and bone marrow failure.

Exposure to hydrofluoric acid

Silicon cell manufacturing also involves the use of hydrofluoric acid, which can cause serious health problems if inhaled or ingested. Symptoms of hydrofluoric acid exposure include burning sensations in the throat and lungs, difficulty breathing, and cyanosis.

However, solar panels are manufactured by following strict health and safety standards to ensure the protection of workers, so no one is exposed to hazardous chemicals during production.

Are the Materials Used in Solar Panels Toxic?

Well, to answer this better, let’s find out what solar panels are made of. Generally, solar panel technology is divided into two categories- those made of silicon cells and those made of thin-film materials.

Silicon Cells

Solar panels meant for home use are exclusively made from crystalline silicon cells.

Crystalline silicon cells are the most commonly used type of solar panel, and they are made of silicon- which is the primary element in many things, such as in rocks and sand.

So, it isn’t toxic at all. However, these solar panels still have other materials built into them, such as small amounts of lead wiring.

But don’t worry, this is sealed with durable glass and an aluminum frame, so the wires are not exposed.


The thin-film panels aren’t meant for residential use and are usually used in solar farms.

These panels are made of different compounds that include toxic elements; some of these elements are mining waste products, such as cadmium.

However, using this waste in producing thin-film solar panels doesn’t contribute to any marginal increase in cadmium production.

In any case, these materials are sealed behind a glass and aluminum frame that is designed to withstand severe wind and hail. Meaning that there is no toxic hazard to the homeowner.

To wrap it up, solar panels are made of materials that are either not toxic or are safely sealed away from exposure. So, you can rest assured that solar panels will not cause cancer or other health hazards.

Can Solar Power Cause Cancer?

Solar panels are safe, but solar power is not. 

There’s no radiation hazard from solar panels themselves, but the solar power plant still needs to be connected to a transmission line for electricity to get into your home or business. 

That means there could potentially be risks of electrocution if you or someone else comes into contact with high-voltage equipment.

There are also solar power plants that use chemicals to store energy in the form of hydrogen gas or molten salt storage tanks, which can be dangerous if they’re not handled carefully. 

If solar panels run out of sunlight and there is no more stored energy for them to convert into electricity, solar systems will shut down safely so you won’t be left without power.

Do Solar Panels Emit Radiation?

As in the case of modern electronics, solar panels produce shallow EM fields and radiofrequency radiation levels.

There are no health concerns associated with RF or EM radiation. Here’s an explanation of why.

RF Radiation

Photons at different frequencies take on different characteristics. 

At a specific frequency, they make visible light, and as the frequency is reduced, it becomes radio waves, also known as radiofrequency radiation. 

If the frequency is increased, it becomes ultraviolet light, and at this point, the radiation is harmful enough to cause health problems.

UV light exposure over a long period of time may eventually cause skin cancer and sunburns.

Crank up the frequency even more, and you get ionizing radiation—the gamma rays and x-rays used in nuclear bombs. 

This radiation is harmless at low doses and can be used for medical purposes, such as dental x-rays.

EMF Radiation

Electromagnetic fields are created whenever electricity flows; they are invisible lines of force surrounding any electrical device.

The strength of an EM field depends on the voltage of the device decreases quickly with distance from the source.

The EMF produced by solar panels is well below the limits set by international safety standards, so there isn’t any health risk.

However, the real risk of EMF exposure comes from prolonged or repeated exposure to high levels of EM radiation.

Continuous exposure can increase the risk of brain tumors, such as glioma and neuroma.

As previously said, Research has shown that there are no health concerns associated with RF or EM radiation at levels below the federal guidelines does not cause harmful health effects.

Solar Panel Certifications

Most manufacturers of solar panels will have some sort of certification to guarantee the safety of their products.

For a solar panel to be certified, it undergoes a series of tests to meet minimum safety standards for environmental and working conditions.

Although these certifications are not always a guarantee of safety, they assure that the panel has been built with the highest standards.

International Electrotechnical Commission

The International Electrotechnical Commission or IEC is a group that sets quality standards for electronic devices worldwide, including solar panels. 

One of the IEC certifications given to solar panels is IEC 61215. This certification includes tests for:

  • Climate, this measures a solar panel’s resistance to conditions like hail, snow, and heavy rain.
  • Electrical safety, this one ensures the panel’s insulation and seals against water and other liquids.
  • Mechanical strength, which evaluates the panel’s physical performance and how well it can withstand physical stressors.

IEC 61730 is another IEC certification focusing on solar panels’ fire and electrical safety and includes the panel’s electrical performance.

Other IEC certifications like IEC 61701 and 60068-2-68 include tests against corrosion caused by salt, especially in solar panels used near the ocean, and sand damage in desert-like regions.

Underwriters Laboratories

You might find the familiar Underwriters Laboratories (UL) label on just about any electrical-related product.

UL is devoted to product safety and offers testing and certification services for a vast array of products made all over the world.

Using testing and science, UL guarantees that products such as solar panels are safe for both consumers and the environment.

A solar panel without either IEC or UL certification is likely a risky investment.

Solar panels must undergo a series of tests to be certified by (UL) or (IEC), so a cancer-causing product would never make it through the process.

Last Words.

In conclusion, solar panels are safe!

Even if they use toxic materials during the manufacturing process. Solar technology is very advanced and has been tested for many years now.

So it’s highly unlikely that you will get cancer as a result of having solar panels on your roof or yard.
