Outdated misconceptions about the toxicity and waste of solar PV modules, including misinformation regarding toxic materials in mainstream PV panels, are hindering the adoption of this.
Incorrect information about toxic materials in PV modules is leading to unsubstantiated claims about the harms that PV modules pose to human health and the environment, fuelling public.
The main component in C-Si panels is silicon, a non-toxic mineral that makes up about 25% of the soil under our feet. Other materials are included in trace amounts, but the main concern is the lead-based solder used to link the individual cells within the panel.
Sampling location, particle size, and sample cutting methods can influence the results in toxicity tests. ASTM E3325-21 is a standard methodology for sampling of photovoltaic modules for toxicity testing. Complementary tests under realistic disposal conditions are better to represent the possible risks.

6 FAQs about [Is the steel strip used in photovoltaic brackets toxic ]
Are photovoltaic panels toxic?
Although most of agriculture ( Haynes, 2009 ). Despite toxic metal components, the PV quickly phase out the use of harmful substances. Figure 1: . Soil concentrations of barium (Ba), cadmium (Cd), copper (Cu), lithium (Li), nickel (Ni), lead (Pb), selenium (Se), strontium (Sr), and zinc (Zn) at varying distances from the photovoltaic panels.
Are photovoltaic modules enriched by metals?
In this study, we analyzed soil taken from beneath photovoltaic modules to determine if they are being enriched by metals (lead, cadmium, lithium, strontium, nickel, barium, zinc, and copper) and metalloids (selenium) present in panel systems. The soil samples were collected from directly beneath c-Si photovoltaic modules and adjacent fields.
Will PV toxicity become irrelevant?
Heather Mirletz, a researcher in circular economy and sustainability of PV at the National Renewable Energy Laboratory (NREL), goes on to tell PV Tech Premium that the most prevalent concerns around PV toxicity may soon become irrelevant.
Are PV modules harmful to the environment?
The International Energy Agency confirmed that the only potential human health and environmental concerns in commercially produced PV modules are the trace amounts of lead in the solder of crystalline silicon modules and the cadmium in CdTe modules 13.
Are PV modules a waste hazard?
This is more than a tenfold increase in the current manufacturing and deployment rate in less than 15 years 1. PV modules are new to many people, so increasing PV deployment has led to growing concerns about the quantity of waste that may arise from decommissioning them (if they are not recycled), and their potential to leach toxic metals.
Do solar panels contain arsenic or chromium?
Arsenic, gallium, germanium and hexavalent chromium, for example, have been listed as present in solar panels by several US state health department websites, despite the fact that the two dominant module technologies, which account for over 99% of the market, contain none of these materials.
