TECHNOLOGY CORE
* CPC reflector
Maximum performance at minimum dimensions.Absorber is bigger than gross surface area. Three dimensionally 360° shaped absorbers for the greatest possible energy collecting surface, utilized up to most of the diffuse and direct radiation from morning to evening.
*The power output higher 50% compare to the normal solar collectors. Smaller installation
area but equal to the same power output.

*Patented fast assembly CPC, flaky sheet, more convenient for the installation and transportation

* With EN12975/Solar Keymark
