Because solar cells have useful lives of 20-30 years, waste generation will lag behind industry growth. Landfill leaching is a modest concern only, because PV materials are largely encased in glass or plastic and many are insoluble. Because of dispersed use, and small amounts of semiconductor material per cell, PV recycling will be challenging.
