Venture capital investing in thesolarindustry is alive and well in 2011. You can see the twenty VC investments in solar in 2011 at the end of this article that cover the solar value chain, as well as spanning early and late stage companies.

But the solar industry has matured in the last decade and the commoditization of the industry has changed the investment criteria for venture investors. Venture returns are achievable -- just look at Mohr Davidow's exit from Recurrent Energy in 2010. (Speakers from MDV and Recurrent will be at the upcoming Greentech Media Solar Summit in Palm Springs.) 

And you can count on a few solar IPOs in 2011.

But the rules have changed since the billion-dollar VC factory buildout festival of 2005 to 2008.

Equity investment in photovoltaics and solar power is no longer a new sector. Greentech VCs have almost a decade of solar experience with several billion dollars invested and more than 200 new companies launched. A dozen VC-funded solar startups have already perished and there are many more to follow.

What do the coming years hold for solar startups and solar investors?

We have a pair of seasoned solar VCs and a DOE funding expert in solar manufacturing speaking on the investment landscape for the coming years at the Greentech Media Solar Summit next week.

  • Peter Shannon, Partner, Firelake Capital
  • Erik Straser, General Partner, Mohr Davidow
  • Scott Stephens, Solar Manufacturing Project Manager, Department of Energy

Come hear these investors speak at our 2011 Solar Summit taking place in Palm Springs on March 14 and 15 and hear from leaders from every part of the solar value chain.
