The truth is that solar panels are made almost entirely with abundant, earth-friendly materials like glass, aluminum, copper, and silicon. However, as the market for solar continues to expand, concerns have emerged about trace toxic compounds used in panels. The first, lead, is widely used for soldering electronic components together.
The materials used in making thin film solar panels can be toxic. These toxic chemicals are introduced into the environment in two stages of a solar panel’s lifespan – production and disposal. During production, these chemicals are gathered, manipulated, heated, cooled, and a plethora of other processes which involve human beings in every step.
With the growth of the solar industry, a significant increase in solar panel waste is anticipated. If not managed correctly, harmful substances, such as cadmium or lead, can leach into the ground, posing risks to soil and water resources.
Exposure to lead, a component in some solar panels, can result in cognitive impairments, developmental delays, and various health problems. Improper disposal or recycling of solar panels containing lead can release lead into the environment, causing contamination of soil and water.
Lead is present in around 33% of the thin coating on top of copper conductors in PV modules, and concerns about lead leaching from solar panels are widespread. However, calculating the leaching potential is challenging.
Arsenic, gallium, germanium and hexavalent chromium, for example, have been listed as present in solar panels by several US state health department websites, despite the fact that the two dominant module technologies, which account for over 99% of the market, contain none of these materials.
Toxic Chemicals In Solar Panels
The toxic chemicals in solar panels include cadmium telluride, copper indium selenide, cadmium gallium (di)selenide, copper indium gallium (di)selenide, hexafluoroethane, lead, and polyvinyl fluoride. Additionally, silicon tetrachloride, a byproduct of producing crystalline silicon, is highly toxic.
