Black Coral Capital, Spring Ventures and other unidentified investors placed a round of funding worth US$50 million with OneRoof Solar, a California-based developer, owner and operator of solar energy generation systems for the residential market.

“While financing remains constrained, it’s great to see growth in venture activity,” said Sheeraz Haji, CEO of Cleantech Group. “Energy Storage emerged as our top sector, indicating continued strong interest in advanced technologies for grid-storage as well as for electric vehicles. Global enterprises continue to investment aggressively into cleantech.”

According to Cleantech Group, VC investments increased 12% compared to US$2.23 billion across 189 deals. In the previous quarter US$1.98 billion was invested across 179 deals.
