San Mateo, Calif., and Stamford, Conn., Sept. 23, 2013—SolarCity (Nasdaq: SCTY), America’s No. 1 full-service solar power provider, and Viridian Energy, a pioneer of affordable clean energy among retail electricity providers, are teaming up to offer solar electricity directly to homeowners at a discount to their current electricity rates through Viridian’s 20,000-contractor network.

SolarCity provides customers with free solar panel installation, and makes it possible for them to pay less for the solar electricity than they currently pay for utility bills, with permitting, installation, insurance, monitoring, and repairs included. Through Viridian and SolarCity, customers are able to have access to clean power at any time of day while reducing their utility bills. They can generate their own clean energy with a solar power system from SolarCity during the day and continue to choose Viridian’s affordable green energy at night and other times when available solar power has been consumed.

 “Viridian and SolarCity have made clean energy more accessible and affordable to a wide range of American homeowners,” said SolarCity CEO Lyndon Rive. “This partnership will help far more homeowners realize that it’s possible for them to pay less for solar electricity than they pay for utility bills.”

Viridian will offer SolarCity’s popular solar power services both to new and existing customers through its extensive network of independent contractors. Viridian will offer SolarCity products and services beginning in its New York, New Jersey, Connecticut, Massachusetts, Maryland and Delaware markets with an expectation to further expand the reach of this partnership in 2014. Viridian currently has more than 230,000 customers in the U.S.

“It is our belief that people want to live a greener lifestyle. Since inception, Viridian Energy has been dedicated to providing clean energy for homes andbusinesses that is also cost effective,” said Michael Fallquist, founder and CEO of Viridian Energy. “The addition of SolarCity products deepens ourofferings and allows customers another way to live a greener lifestyle. We are pleased to announce the addition of SolarCity products to our customers.”

SolarCity’s solar power systems typically produce the most energy in the middle of the day, when the sun is brightest, and provide any unused energy back into the grid to be consumed at the nearest point of demand. SolarCity customers typically receive credit for putting excess green power into the grid, which can be used to offset their remaining utility bill. Viridian’s energy is used at night, or at any other time when more power is needed than is being generated with solar panels. In this way, SolarCity and Viridian can provide a clean power option far more affordably than is otherwise possible.

Viridian will begin making SolarCity services available to its customers this week. More information is available at www.viridian.com
