1. sunlight concentrators make the efficiency doubly increased.
2. Fast assembly CPC concentrators more easy installation and transportation.
3. 360°sunlight absorber, hot water in cloudy days.
4. Overheating protection just disassembly the CPC concentrators in summer.
5. Temperature startup more faster than the normal solar thermal collectors.
6. Applicable for the industry heating.
7. More thermal production based on the same aperture area.
8. EN12975/Solar Keymark.
* 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
