Vivint Solar sees $1.9bn market cap

That compares to the current $6.3bn market cap of sector leader SolarCity.

Vivint Solar’s IPO will be closely watched by investors far beyond the clean-tech sector, given the spectacular run-up in SolarCity shares, which floated at $8 each in late 2012 and currently trade at $68 – making it more valuable than US solar giants like SunPower and SunEdison.

Vivint Solar commanded a 9% share of the US residential installation market in the first quarter of 2014, compared to SolarCity’s 29% market share, according to GTM Research.
