We spoke with Brendon Merkley, the COO of Vivint Solar, just last month. Vivint is the second-largest solar installer in the U.S. behind SolarCity (SCTY).

GTM has learned from sources close to the company that Merkley has resigned from Vivint to join -- wait for it -- SolarCity. Vivint has confirmed that Merkley has left the firm. SolarCity has confirmed that Merkley is joining the firm.

This defection to SolarCity follows Vivint Solar's CEO Tanguy Serra's move to SolarCity in April of this year. Sources indicate that the departure of Serra was less than cordial. Alex Dunn replaced Serra as CEO.

Both SolarCity and Vivint are vertically integrated, and in an interview last month, Merkley admitted that "SolarCity is the analogue."

There's plenty of intrigue ahead as these two fast-growing installers jockey for personnel, funding, technology and customers.

 

Plug Power's CTO Adrian Corless resigned from his position at the fuel cell company. Keith C. Schmid was named COO of the struggling public firm. Previously, Schmid was president of SPS Solutions, a communication systems integrator.

 

EnTouch Controls, a provider of energy management systems for small businesses and light commercial facilities, named Jon Bolen, formerly EVP at Westec Intelligent Surveillance, as COO.

In August we reported that Recyclebank had run into some financing trouble along with some layoffs. The firm was to undergo an "aggressive realignment." We just learned that CEO Jonathan Hsu has been moved to advisor and replaced by Javier Flaim, while COO David Eisendrath has stepped down. In an email to GTM, newly installed CEO Flaim wrote, "Our business is healthy. We’ve experienced strong growth and success over the past three years, with membership tripling, an installed base expanding to all 50 states, and key strategic partners such as SC Johnson (who is still a partner), Johnson & Johnson, Unilever and Waste Management committed to long-term impact. Recyclebank lets consumers receive coupons and rewards for recycling, energy efficiency, and energy conservation." KP's Trae Vassallo called it a way to "get consumers aligned" with the goal of recycling. The firm claims it has 4.5 million members.
