The rapid expansion of solar energy has led to record installations, with 597 gigawatts added in 2024. A significant concern arises regarding the potential waste generated as solar panels reach the end of their 25- to 30-year lifespan. Projections estimate that by 2050, global solar panel waste could amount to 78 million tons. Most panels are recyclable, containing materials like glass, silicon, and metals; however, some also include hazardous elements. The recycling industry is responding, with growth anticipated in the market for recycling services by 2030.
Solar power has become the driving force of the global energy transition. In 2024 alone, the world installed a record-breaking 597 gigawatts of solar capacity - a 33% increase over 2023.
The International Renewable Energy Agency (IRENA) projects that global solar panel waste could reach 78 million tons by 2050, equivalent to disposing of more than 4 billion of today's panels.
While about 75% of a panel's weight is recyclable glass, panels also contain valuable materials including silicon, silver, copper, aluminum, and potentially hazardous materials like cadmium and lead.
The global solar panel recycling market is projected to grow from $384.4 million in 2025 to $548 million by 2030.
