Are Solar Panels Toxic To Make

Solar panels are an increasingly important source of renewable power that will play an essential role in fighting climate change.

Are solar panels toxic to make.

The toxic chemicals are a problem at the beginning of a solar panel s life during its construction and at the end of its life when it is disposed of. Panel manufacturer jinko solar for example has faced protests and legal action since one of its plants in the eastern province of zhejiang was accused of dumping toxic waste into a nearby river. Solar panels significantly reduce the pollution and toxic chemicals that coal emits. And because solar panels contain toxic materials like lead that can leach out as they break down landfilling also creates new environmental hazards not only are solar panels not required to be recycled their disposal can lead to potential environmental problems.

There are some chemicals used in the manufacturing process to prepare silicon and make the wafers for monocrystalline and polycrystalline panels one of the most toxic chemicals created as a byproduct of this process is silicon tetrachloride. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel. The millions of solar panels being dumped in landfills are a veritable toxic cocktail of gallium arsenide tellurium silver crystalline silicon lead cadmium and other heavy metals. And as it produces electricity it isn t emitting greenhouse gases and pollution at all.

While solar panels are considered a form of clean renewable energy the manufacturing process does produce greenhouse gas emissions. And because solar panels contain toxic materials like lead. Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants. These two intervals are times when the toxic chemicals can enter into the environment.

Additionally to produce solar panels manufacturers need to handle toxic chemicals. Then there s the landfill legacy being created by wind turbine blades with the first world cynically using the. Environmental scientists and solar industry leaders are raising the red flag about used solar panels which contain toxic heavy metals and are considered hazardous waste. When these panels enter landfills valuable resources go to waste.

Worse rainwater can wash many of these toxics out of the fragments of solar modules over time. However solar panels are not emitting toxins into the atmosphere as they re generating electricity.
