While solar panels are considered a form of clean, renewable energy, the manufacturing process does produce greenhouse gas emissions. Additionally, to produce solar panels, manufacturers need to handle toxic chemicals. However, solar panels are not emitting toxins into the atmosphere as they generate electricity.
In other words, from an environmental point of view, insufficient toxicity and risk information exists for solar cells.
Insufficient toxicity and environmental risk information currently exists. However, it is known that lead (PbI 2), tin (SnI 2), cadmium, silicon, and copper, which are major ingredients in solar cells, are harmful to the ecosystem and human health if discharged from broken products in landfills or after environmental disasters.
This chapter has shown the potential of some materials and chemicals used in the manufacture of thin film PV solar cells and modules to be hazardous. These hazardous chemicals can pose serious health and environment concerns, if proper cautions are not taken.
Current and emerging photovoltaic modules may include small amounts of toxics. Global toxicity characterization policies for photovoltaic devices are compared. Sampling approach, particle size, and methods cause leachate result variability. Limitations of current assessment procedures and regulations are disclosed.
The PV industry uses harmful and flammable substances, although in small amounts, which can involve environmental and occupational risks. The main environmental impacts of solar panels are associated with the use of land, water, natural resources, hazardous materials, life-cycle global warming emissions etc.
