Vivint Solar chooses Enphase as 2013 inverter supplier

PETALUMA, Calif., April 3, 2013 -- Enphase Energy (Nasdaq: ENPH) today announced the renewal of its relationship with Vivint Solar, Inc. to be their inverter solution for 2013. Vivint Solar is an affiliate of Vivint Inc., a leading provider of home technology services in North America.

"We are delighted to continue building off our powerful strategic relationship with Vivint Solar. For over a year-and-a-half, our advanced inverter technology, coupled with Vivint Solar's unique go-to-market, has helped accelerate them toward their goal of becoming the top U.S. installer of residential rooftop solar systems," said Jeff Loebbaka, senior vice president of worldwide sales and field operations of Enphase Energy.

Vivint Solar customers save money on energy through a power purchase agreement (PPA) in which customers agree to buy the power generated by a solar photovoltaic system installed on their home, at rates that are generally lower than their local utility. In exchange, Vivint Solar designs, installs, operates and maintains the system with no additional out-of-pocket costs for the customers. This business model provides homeowners the benefits of renewable solar energy without a large, upfront investment.

"We are focused on nationwide expansion of our affordable solar offering, and we adopted Enphase early on because of the value their inverter solution delivers," said Dan Rock, vice president of installs of Vivint Solar. "Enphase inverters provide flexibility to Vivint Solar's installation crews and provide Vivint Solar's customers with more efficient solar energy systems, resulting in enhanced savings to our customers."

Vivint Solar currently operates in California, Hawaii, Maryland, Massachusetts, New Jersey, New York, and Washington D.C. For more information on Vivint Solar's products and services, visit www.vivintsolar.com.
