SolarCity (NASDAQ:SCTY.DL) got the blessing of Standard & Poor's this week. The ratings agency said that SolarCity's recent bonds are reated at a BBB+, an investment grade rating. This should actually come as a surprise for some investors because it got that rating despite not having a long credit history and it got a better rating than some of the other utility giants such as Duke Energy (NYSE:DUK) and Exelon (NYSE:EXC).
