SunCatcher concentrating solar power plant goes live in Peoria, Arizona

Tessera Solar has just completed a new Concentrating Solar Power (CSP) plant in Peoria, Arizona, that uses 60 SunCatcher solar collectors to generate 1.5 megawatts of electricity.  The SunCatcher collectors are made by Stirling Energy Systems and use a mirrored parabolic dish that tracks the sun.   The sun’s rays are focused on a hydrogen gas filled piston that drives a Stirling engine to generate electricity.   Stirling Energy says that its system is more efficient and uses less water than other CSP systems.   Each SunCatcher dish can generate 25 kilowatts.

As you can see from the picture – these SunCatchers are pretty large.   The guy standing in the middle of the field gives you a sense of scale.   When I first saw this, I thought that this would be a good system for a house or a small business to generate its own electricity, but obviously these things are far too big for that.

Tessera Solar has a number of other SunCatcher solar projects  under development.  For more details, check out the Tessera Solar web site.
