Not All Solar Applications are Created Equal

So far I’ve shown a basic iso-IRR curve (in the earlier post “Low-efficiency penalty”) to get a sense for the penalty that low-efficiency modules have to pay.  (The quick overview:...

The Low-Efficiency Penalty in Solar

“Dollar per watt” can be a misleading number.  For those who aren’t familiar, if you sell a 150-watt module for $300, that’s $2/watt.  Pretty simple. However, even though it’s a common...

A New Metric: Burdened LCOE

Renewable energy isn’t yet competitive with fossil fuels.  I don't think that's news.  However, it’s an unfair fight.  And I’m not talking about carbon pricing (which would be nice). ...
