What are solar panels made of?
The main component of a solar panel is silicon, which makes up both the photovoltaic cells and anti-reflective glass.To make the cells, electricity is used to melt sand, whichis then purified, distilled and formed into waffles. Finally, it has an anti-reflection coating of silicon nitride to maximise the absorption of light. The coating is blue because dark colors absorb more sunlight, making the panels more efficient, and although a black coating would absorb more sunlight, they also heat up much faster and solar works best at lower temperatures. The blue coating absorbs the light well, but the surface remains cooler, so the panels generate electricity more efficiently.
The horizontal and vertical lines on the solar panels are printed silver conductors. They conduct the generated electricity from the silicon cells to the cabling.
The solar panels are mounted on aluminum frames, which have a matte non-reflective finish. The frames have a galvanized screwed foundation, making them easy to assemble and dismantle. As a result, the soil is quickly restored after the solar farm has been dismantled.
Because solar panels are made of silicon, silver and aluminum, they are fully recyclable and do not cause any contamination. There are also no emissions in the production of electricity.
