150 Solar Startups

Over the last four years VC investment in solar has gone from a modest trickle to a roaring flood. In 2005 VCs invested about $200 million in solar startups. When the dust settles at the end of 2008, they will have invested about $4.5 billion in about 150 new solar startups in the four years from 2005 to 2008.

We've compiled a list of these firms with funding info and a few words on each startup's technology.
