Sunrun Inc., the largest U.S. residential-solar company, is seeking about $500 million to fund more rooftop-power systems, according to people familiar with the company’s plans.
South African bank Investec Plc is leading the five-year deal, according to the people, who declined to comment because they weren’t authorized to speak publicly. The funds would refinance and expand an existing credit facility and represent the company’s biggest non-recourse debt financing deal to date. Sunrun declined to comment Thursday.
