SUNRUN LAUNCHES MYSUNRUN GIVING HOMEOWNERS MORE TOOLS TO ENGAGE WITH THEIR HOME SOLAR SYSTEM

Leading Residential Solar Company Unveils Interactive Customer Tool; Continues Focus on Building Technology That Simplifies Home Solar

SAN FRANCISCO - January 12, 2015 - Sunrun Inc. (Nasdaq: RUN), the largest dedicated residential solar company in the United States, today unveiled mySunrun, a powerful new tool for customers to interact with their home solar system. The mySunrun tool encompasses an enhanced customer website and new mobile phone app, which provide Sunrun customers with new ways to track production, socially share savings insights with friends and manage their customer accounts.


With mySunrun, customers have access to the following capabilities:

• Electricity tracking: At the touch of a button, users can access their solar electricity production in real-time and monitor their solar system's production by week, month and year.

• Social sharing: With built-in social media tools, mySunrun makes it easy for customers to share the benefits of going solar with family and friends. Homeowners can have fun sharing facts about the electricity their system has generated with others via Facebook, Twitter and through text messages, demonstrating how home solar not only saves them money, but also is good for the environment.

• Easy referrals: mySunrun makes it simple for customers to instantly and on the go refer others to Sunrun. Customers can view past referrals and money earned on the app or though the mySunrun website.

"Sunrun solar puts customers in control of how they generate and use electricity in their home. The new mySunrun will provide the tools they need to better understand their solar system and the impact it's having on their wallet and in creating a better world to live in," said Michael Grasso, chief marketing officer at Sunrun. "Our customers are also our biggest advocates - simplifying how they can share the benefit of Sunrun is our priority. We will continue to invest in creating a fantastic customer experience and mySunrun is a major component of this."

The mySunrun app can be downloaded for Android and iOS through Apple's App Store, Google Play or on sunrun.com.

The mySunrun tool builds on Sunrun's history of developing proprietary tools and technology that simplify the entire home solar process, from design to installation and beyond. In 2014, the company unveiled Sunrun BrightPathTM, a cloud-based automated software platform for Sunrun and its partners that streamlines the solar process from selecting hardware to system design through pricing, scheduling, permitting, installation and beyond.

Since 2007, Sunrun has made going solar simple for homeowners by customizing their solar system to their lifestyle and savings goals. Through its solar as a service model, Sunrun makes it simple for consumers to learn about and get solar for their home - whether online, over the phone, in retail environments or even at professional baseball games.
