Solar concentrators seem perpetually to be the zero-billion-dollar market in green technology, but times are changing.
Soliant, which spun out of Caltech, has come out with a new version ofits concentrator/PV module system that it says can deliver power for"the lowest price per kilowatt hour for commercial rooftopinstallations," or 8 cents per kilowatt hour.
The new product, the SE-1000x, contains eight solar modules pertracking panel and can deliver up to 504 watts of power. The earlierversion, the SE-500, contained six modules. Soliant’s system actually combines two concentrators and relies on a somewhat exotic III-V materials solar cell, not a crystalline silicon cell. The SE-1000 concentrates sunlight 1,000 times. The old one concentrated it 500 times. A tracker to more accurately aim the system at the sun is also part of the package.
