Venture capital funding of greentech firms totaled $2.6 billion in the first quarter of 2011 -- an extremely strong showing, albeit with a leaning towards later-stage deals. VC investment in green firms in the most recent quarter was similarly strong. We'll get you a list of every deal tomorrow. In the meantime, here's a quick snapshot of thesolardeals in the most recent quarter.

The biggest solar deal this quarter was:

  • Suniva with their $115M round D, closed after suspending their request for a DOE loan guarantee.  

I have learned not to interpret strong VC numbers as a proxy for a healthy greentech industry or the sectors therein. If that were the case, we would all be driving cars fueled by corn ethanol and every electricity consumer would be programming a home energy monitoring appliance. Here's the list:
