Solar financing is still a relatively new phenomenon but it's come a long way in just the last few years. Berkshire Hathaway (NYSE:BRK-A) recently sold $1 billion in financing for a utility-scale project, and SunPower (NASDAQ:SPWR) and SolarCity (NASDAQ:SCTY) are two of the leasing leaders who have developed financing that brings in tax equity. 

The next step is securitization, REITs, and MLPs, which may not be far off. Motley Fool contributor Travis Hoium covers where the industry has been and where it's going in the video below.
