What is the Difference Between Mono Solar Panels and Poly Solar Panels in Terms of Ecological Footprint?
Both monocrystalline and polycrystalline panels are made from silicon, a conductive material that allows photovoltaic cells in solar panels to generate electricity from solar radiation. Silicon is not found in its natural state but comes from silica, a chemical element found in our earth’s crust.
Once extracted, the silica is refined into silicon to then be crystallized in the form of ingots which will finally be cut into thin strips (commonly known as wafers). All of these processes have a high ecological footprint since they are polluting and energy-consuming.
That said, the ecological footprint of a monocrystalline solar panel is higher than that of a polycrystalline solar panel since its manufacture causes two to three times more material loss. However, knowing that the efficiency of monocrystalline solar panels is higher than that of polycrystalline solar panels, its ecological footprint will be compensated faster than that of a polycrystalline solar panel.
