Solar market consolidation continued today with Silicon Valley-based CaliSolar agreeing to buy Ontario, Canada-based 6N Silicon. No financial terms were disclosed, but VC backers of both companies agreed to invest an additional $22.5 million.
This puts CaliSolar’s total VC funding at around $85 million, putting it in 18th place among all VC-backed solar companies. I figured it’s worth taking a quick look at the top five, since they are the most likely private acquirers going forward:
Location: Fremont, California
Business: Solar panels for commercial rooftops
Investors: Argonaut Ventures, Madrone Partners, U.S. Venture Partners, Rockport Capital Partners, CMEA Capital, Redpoint Ventures and Virgin Green Fund.
Notes: Solyndra filed for a $300 million IPO last December, and has received more than $535 million in government loan guarantees.
