New Software Will Reduce Time and Costs of Going Solar and Improve Customer Satisfaction

SAN FRANCISCO - November 16, 2015 - Sunrun (NASDAQ:RUN) and Clean Power Research today announced they have been awarded $900,000 by the U.S. Department of Energy SunShot Initiative to develop and deploy the first end-to-end solar permitting and interconnection software application for installers. The software will make it possible to automatically generate and electronically submit solar PV permit and interconnection applications. Online submissions will dramatically reduce the time and costs involved with permitting and interconnection, enabling faster project completion, lower costs, and happier customers.

"When a customer chooses to go solar, a residential solar permit is required. There are 18,000 building permit agencies in the U.S. and most have their own application process and rules," said Gary Wayne, vice president for strategic projects at Sunrun. "Typically, this process is costly and adds up to four weeks of delay to a homeowners system installation timeline. The goal of the SunShot Incubator 10 project is to cut these costs and delay time in half - a big win for the entire industry that will help Sunrun create an even better customer experience."

With the support of the SunShot Initiative, Sunrun and Clean Power Research will integrate their software platforms and add in new functionality that will automate the permitting process. As a result, Sunrun BrightPath™ users will be able to enter customer and system design information only once and automatically apply for permits and interconnection from utilities using Clean Power Researchs PowerClerk®.

"Clean Power Research has seen huge success helping to reduce soft costs stemming from interconnection and incentive processing," said Jeff Ressler, president of software services at Clean Power Research. "With this project, well leverage that experience to streamline permitting. Not only will the solar industry benefit, but building permit agencies will be able to leverage the same PowerClerk platform that utilities and energy agencies are using today to process more than 12,500 interconnection and incentive applications per month."

Through previous Incubator 8 awards, SunShot partially funded the development of both Sunrun BrightPath and Clean Power Researchs PowerClerk Interconnect. Sunrun BrightPath is a proprietary software platform that manages the home solar process from selecting hardware to system design, pricing, scheduling, installation, and beyond. PowerClerks award-winning software brings application processing online for faster, smarter energy program management.
