“Constellation is dedicated to providing our customers with innovative, clean energy solutions, and home energy technologies to meet their unique residential energy needs,” said Bruce Stewart, senior vice president and chief marketing officer for Constellation. “We have a long history of providing solar solutions to our commercial customers and we are pleased to work with Sunrun to offer affordable solar solutions to our residential customers. This is another key step in executing Constellation’s strategy to deliver a broad set of home energy services and technologies to our residential customers to help them effectively manage their energy costs.”

Sunrun will enable homeowners to install solar without the high upfront cost and complexity of ownership. Sunrun pays for the solar installation and insures, monitors, maintains and guarantees performance of the system for 20 years. Customers simply purchase power generated from their Sunrun system at a rate that is less than their current electric utility rate, and can continue to receive electricity supply from Constellation if additional power, beyond what their solar energy system generates, is required.

“With Sunrun, homeowners across the Mid-Atlantic and Northeast can simply access the benefits of going solar without the hassle of upfront costs or maintenance,” said Matthew Woods, senior vice president, partners at Sunrun. “Sunrun is pleased to work with Constellation to make it even easier for more families to enjoy energy choice and savings.”

Constellation’s partnership with Sunrun complements the company’s home services and renewables business. Constellation has a total of 275 megawatts of distributed commercial solar projects completed or under development across the country. Additionally, BGE HOME, Constellation’s home energy services provider in Maryland, will also offer its customers the opportunity to install Sunrun systems.

The relationship supports Sunrun’s unique approach to meeting consumers’ needs through a variety of channels and partners, including in retail environments, online, through local installers or bundled with other consumer services. Sunrun is committed to bringing clean, affordable solar energy and an exceptional customer experience to more consumers through its partners.

To be eligible for Sunrun, customers must own their home, spend about $100 a month on their electricity bill and have a roof in good condition with favorable sun exposure.
