An NRG spokesman tells Recharge the company is on track to announce a “resolution” for its residential PV business by the end of June.

"We can confirm that Kelcy is no longer with NRG," the spokesman says. "We wish him well in his future endeavors."

In 2014 New Jersey-based NRG acquired Pegler’s company, Roof Diagnostics Solar, in a bid to take on sector leaders SolarCity and Vivint Solar.
