US Department of Defense agencies are leading the nation on the renewable energy front. With plans to have 25% renewable energy use by 2025 and spending $15.2B on DoD energy in 2010, this is a significant and growing market place for the solar energy industry. DoD energy is segmented into basing power (mostly electricity), operational [...]

Understanding Photovoltaic Cell and Module Level Efficiency

Dave Buemi — Wed, 02 Nov 2011 12:02:51 +0000

After a recent presentation during a government renewable energy conference, I received a number of questions regarding why there was such a large difference between crystalline solar cell efficiency and a fully packaged and weatherized module. For instance, a 19% efficient crystalline photovoltaic (PV) cell, when packaged into a module with 60 cells results in [...]

Where did global warming go?

I took some time off from posting here as a result of a number of events. Two dear friends passed away in late June, it was good time to step away and reflect on what is important. In July, I ended my PV industry consulting practice and have taken a position with Suniva, Inc., an innovative American [...]
