[archive 2009] @arfisk @beyondzeronews Concentrated Solar Thermal Versus Concentrated PV

A Hawaiian based concentrated solar thermal company called Sopogy has been making headlines recently with it's trough based system being used by Sempra Energy utility Southern California Gas Company (SoCal Gas) in combination with a thermal air conditioning unit to demonstrate the power of a solar air-conditioning demonstration system. The small-scale solar thermal startup has substantial investor backing from the likes of eBay founder Pierre Omidyar, Ohana Holdings so we thought it was worth a closer look at the fairly simply constructed solar thermal collectors to see what all the fuss is about. According to Sopogy's own application notes the systems is not very efficient. They specify a 40% loss from solar to thermal and a further 80% loss thermal to electric. That gives an overall electric generation system efficiency of just 12%. This means that a single 5.57m2 trough...
