Does Making Solar Panel Create Waste

A fraction of solar panels use cdte as the semiconductor material.

Does making solar panel create waste.

Lead and silver are captured in the waste stream for all solar panels but the cadmium is the most problematic waste generated by manufacture and disposal of solar panels is cadmium. Even for cdte solar panels nuclear power generates more cadmium waste on per unit energy basis. A closer look at solar panels opens a wide array of questions that need answers. However solar panels are not emitting toxins into the atmosphere as they re generating electricity.

Most manufacturers recycle this waste to make more polysilicon. The problem of solar panel waste is now becoming evident. Additionally to produce solar panels manufacturers need to handle toxic chemicals. Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants.

As environmental journalist emily folk admits in renewable energy magazine when talking about renewable energy the topic of waste does not often appear she attributes this to the supposed pressures of climate change and alleged urgency to find alternative energy sources. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel. Worse rainwater can wash many of these toxics out of the fragments of solar modules over time. Solar photovoltaic panels whose operating life is 20 to 30 years lose productivity over time.

Fabricating the panels requires caustic chemicals such as sodium hydroxide and hydrofluoric acid and the process uses water as well as electricity the production of which emits greenhouse gases.

In 2011 hydrofluoric acid used by the company for solar panel manufacturing contaminated river water killing hundreds of fish and dozens of pigs.

While solar panels are considered a form of clean renewable energy the manufacturing process does produce greenhouse gas emissions. The international renewable energy agency estimated that there were about 250 000 metric tons of solar panel waste in the world at the end of 2016 and that the figure could reach 78 million metric tons by 2050. Solar panels produce tons of toxic waste literally. Solar panels generate mountains of waste they also heat the planet blanket wildlife habitats and cause other ecological damage wind solar.
