Waste solar photovoltaic panels have extremely high recycling value, with a material recyclability rate exceeding 95%. It is estimated that by 2030, the cumulative value of raw materials recycled from photovoltaic panels globally will reach US$450 million; by 2050, this cumulative value will exceed US$15 billion. Crystalline silicon photovoltaic panels are mainly composed of glass, aluminum, silicon, copper, and precious silver, among other materials:

Aluminum (approximately 10% of total weight): Primarily from the frame. Aluminum recycling technology is very mature, achieving 100% purity, and the recycling price per ton can reach thousands of US dollars, making it the most significant direct profit point in the current recycling industry chain.

Glass (approximately 70% of total weight): Mainly high-purity ultra-clear tempered glass. Although the price of waste glass itself is not high (approximately 600 yuan/ton), after high-purity stripping using specialized equipment, it can be reused as an industrial raw material.

High-value metals (silver and copper): Although silver and copper account for less than 1% of photovoltaic panels, they have the highest economic value. Through pyrolysis and chemical purification technologies, copper and silver powders with a purity of up to 99% can be refined, significantly increasing the recycling premium of the entire photovoltaic panel.

Silicon (approximately 5% of total weight): Low-purity industrial-grade silicon recovered from old panels is worth about $2/kg. If purified to “solar-grade silicon” (costing approximately $25/kg) using advanced processes, its recycling benefits will increase exponentially.
