Who is Vivint Solar?
Vivint Solar is a residential solar installer and financier that primarily sells systems through solar leases. The company is No. 2 in residential solar market share, behind the U.S.'s largest SolarCity (NASDAQ:SCTY) and ahead of installers like SunPower (NASDAQ:SPWR), Sungevity, and Verengo.

Offering direct sales, usually door-to-door, differentiates the company, and standardization of components helps lower costs on its installations. The sales strategy has led to a highly concentrated market share in small regions in the Northeast, such as Boston.

As of June 30, 2014, the company had installed 21,921 solar systems totaling 129.7 MW, with $647.5 million in estimated contracted payments remaining, and $246.2 million in retained value under contract.

One key number to watch will be growth for Vivint Solar. The company is still new in the solar industry, but it grew installations an astounding 231% in the first half of this year. Growing anywhere near that rate into the future could bring it to the same scale as SolarCity atop the residential solar industry, creating a great growth opportunity for investors. 

At the very least, this is a solar company worth watching, and we'll be covering Vivint Solar along with the rest of the industry on Fool.com.
