The majority of the market share for solar panels is held by crystalline-silicon technology. This kind of panel is made of silicon solar cells, a plastic junction box, polymer layers, copper wire, glass, and a back-sheet. Although the polymer layers protect the panel from the elements, they also make recycling and disassembling the panel challenging because high temperatures are frequently needed to remove the glue. Many of these parts are recyclable.About 75% of the weight of a solar panel is made up of glass, and recycling glass is a well-established business. The copper cable, plastic junction box, and aluminum frame are additional easily recyclable materials. Other components found inside solar cells might be more challenging to recycle. Panels frequently contain relatively modest amounts of silver and internal copper, despite the fact that these minerals are valuable components. Solar panels might also contain harmful elements like lead and cadmium. Critical elements such as galli
