We recently reported that solar financier Vivint Solar's CEO Tanguy Serra had "stepped down as CEO" and would remain with the company as an advisor.

Alex Dunn replaced Serra as CEO. Vivint was recently acquired by Blackstone for $2 billion.

Well, we've just learned from a reliable source that the departure of Serra was less than cordial, and that Serra is headed toward an operational role at Vivint competitor and recently public SolarCity (SCTY).

SolarCity also named Jimmy Chuang as VP of Structured Finance and former equity researcher Aaron Chew as VP of Investor Relations. Chew will frame SolarCity's financial performance, strategy and growth prospects to analysts and investors. Chuang joins SolarCity after holding developer and financier roles at GCL Solar Energy, Fotowatio Renewable Ventures and MMA Renewable Ventures.
