In a solar industry in transition, with daily news of consolidation and attrition, SolarCity's hiring situation warrants notice. The solar and energy efficiency installer and financier has more than 300 job openings across the country, according to its website. SolarCity hired 100 new employees in June to bring its total workforce to more than 1,900 in 14 states. 
U.S. solar capacity doubled in 2011 over 2012, and increased 85 percent in the first quarter of 2012 over the same period in 2011, according to GTM Research. Much of the job growth has come in the downstream installation and financing sector.
