Toxic Substances In Solar Panels

A solar panel converts the sun s radiant energy into electricity using photovoltaic cells commonly known as solar cells.

Toxic substances in solar panels. The california department of toxic substances control dtsc is poised to classify solar panels as a subset of hazardous waste known as universal waste a change that legal experts say makes recycling the panels easier in several ways. Silicon tetrachloride a byproduct of producing crystalline silicon is also highly toxic. 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. California s department of toxic substances control dtsc held a meeting with solar and waste industry representatives to discuss the disposal issue.

These two intervals are times when the toxic chemicals can enter into the environment. The solar energy advocates who only see cheap electricity with rose colored glasses are oblivious to the reality of cost toxic chemicals environmental pollution and health hazards to humans. However solar panels are not emitting toxins into the atmosphere as they re generating electricity. Key ingredients in a solar panel include solar cells photovoltaic modules and semiconductors.

Additionally to produce solar panels manufacturers need to handle toxic chemicals. The representatives and dtsc. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel. Because california s solar panels end up in landfills at the end of their useful life the state is in the process of implementing regulations to change that.

According to cancer biologist david h. The department of toxic substances control dtsc regulatory assistance office responds to inquiries from the regulated.

This guidance was prepared by the regulatory assistance office of the department of toxic substances control dtsc and answers frequently asked questions received by the dtsc electronic waste enforcement team.

While solar panels are considered a form of clean renewable energy the manufacturing process does produce greenhouse gas emissions. With recycling expensive. Solar panels may be an appealing choice for clean energy but they harbor their share of toxic chemicals.
