New investments into renewable energy projects globally are down significantly this year, as European uncertainty, and a late extension of renewable subsidies in the United States, curbed production starts.

SolarCity (NASDAQ:SCTY) continues to grow its solar panel leasing business, with 475 MW to 525 MW of installed capacity expected next year, from a base of 270 MW expected in 2013. Leasing competitor and high-quality solar manufacturer SunPower (NASDAQ:SPWR) continues to outperform its peers in 2013.
