Solar ETF List – Best ETF Highlights

Until recently it has been a wild ride for long term investors in the Solar sector. Performance of Solar ETFs tracking the a basket of solar energy stocks has been mixed at best. Solar energy stocks has struggled due to declining PV cost per unit which appears to be bottoming. The decline in PV cost resulted in difficulties across the solar industry hence Solar ETFs had a volatile 2012 and 2013 where they under performed the market significantly.

Solar energy has been consistently the fastest growing sector within the alternative energy space. Total Global Solar PV capacity increased from 40 GW to 100 GW between 2010 to 2012. The top 5 countries leading additional investment in solar capacity led by Germany are Italy, China, United States and Japan.

Solar Energy Sector broadly can be broke down into

  1. Solar Photovolatic Cells with global capacity in 2012 10 times its 2007 size.
  2. Concentrated Thermal Power which over the same period grew 7 times its 2007 by 2012.
