Solar energy is a rapidly growing market, which should be good news for the environment.  Unfortunately there’s a catch.  The replacement rate of solar panels is faster than expected and given the current very high recycling costs, there’s a real danger that all used panels will go straight to landfill (along with equally hard-to-recycle wind turbines).  Regulators and industry players need to start improving the economics and scale of recycling capabilities before the avalanche of solar panels hits.
