Last week, we blogged here about a $100M tax equity fund to finance residential solar installations.

The installations were to be performed by a company call SunRun. On Tuesday, June 29th, SunRun announced it closed a Series C round of funding for $55 million led by Sequoia Capital and joined by existing investors Accel Partners and Foundation Capital.

For those of you not wise to the VC world, Sequoia is the biggest and baddest Silicon Valley VC that there is. You may have heard of prior early stage investments like Google, YouTube, Apple, Yahoo!, and Cisco, among others.

Original investor, Accel Partners, is bigtime too with investments in Facebook, Veritas, and comscore.

Similarly, a recent report from Matter Network states that Goldman Sachs has begun covering the solar sector, including First Solar and SunPower.
