Recycling Solar Panels to Reduce e-Waste
What are Solar Panels Made Of? There are two types of solar panels: silicone-based and thin-film. About 90 – 95% of the panels we use are silicone based – those are the familiar black panels you see on many rooftops. These panels are made up of silicon solar cells (PV cells) laid in a grid and connected by strips of metal.
