Many panels use heavy metals such as cadmium, lead, and even small amounts of arsenic. These substances can leach into the soil and groundwater if panels are improperly disposed of or dumped in landfills..

The claim that heavy metals like lead and cadmium in solar panels leach into groundwater and pose serious health risks is not supported by scientific evidence. The materials used in solar panels, specifically cadmium telluride and lead, are safely contained within the panels and pose minimal. .
Toxic heavy metals in solar panels are locked in stable compounds and sealed behind tough glass, preventing escape into air, water, or soil at harmful levels. Most concern focuses on cadmium and lead. 40% of new U.S. panels use cadmium telluride, which does not dissolve in water, easily turn to. .
Common toxic materials found in solar panels primarily include heavy metals such as lead, cadmium, arsenic, selenium, and sometimes silver and copper. These materials are used in the semiconductor and solder components of the panels, and at high enough levels, they can be classified as hazardous. .
By 2050, the International Renewable Energy Agency estimates there could be up to 78 million tons of solar panel waste worldwide. This is a staggering figure, considering the enthusiasm with which solar energy has been promoted as a “clean” solution. In countries like Japan and Germany, the problem. .
The Massachusetts Department of Energy Resources has assessed that there is little, if any, risk of chemical releases to the environment during normal use, and that all materials in a solar panel are "insoluble and non-volatile at ambient conditions," and "don’t mix with water or vaporize into. .
Overall, the period from 2008 to 2023 saw the U.S. solar capacity grow from 0.34 GW to 137.73 GW, highlighting the sector's substantial expansion and its critical role in the nation's energy landscape. But a problem emerged in the early 2020's as the volume of end-of-life panels began to increase:.
