GreenRay

GreenRay, Inc. operated as a developer of integrated solar appliances for residential and commercial applications, headquartered in Westford, Massachusetts. The company was established in 2006 by former employees of Schott Solar, with Miles C. Russell serving as the founder and CEO.

The firm's core business centered on simplifying solar energy systems through modularization. It developed what it termed the world's first "solar appliance," the SunSine™200 AC Module. This product was an integrated, plug-and-play photovoltaic system that combined a PV module, a proprietary micro-inverter, mounting, and wiring into a single package. This design converted direct current (DC) to alternating current (AC) at the panel level, aiming to reduce installation complexity and costs while offering a scalable solution for home and commercial solar installations.

GreenRay's financial history includes securing approximately $3.5 million in grants and loans from federal and state governments upon its founding. A significant milestone was achieved in July 2009 when the company raised $2 million in a Series A funding round with participation from investors The Quercus Trust and 21Ventures. This capital was intended to facilitate the move to manufacturing and product launch. Subsequently, in August 2010, the SunSine™200 AC Module obtained the ETL mark for the U.S. after being certified by Intertek for safety and grid connectivity according to the UL 1741 standard. The company's trajectory culminated in its acquisition by SunEdison on August 1, 2011.
