Quality &Safety & Power Warranty
* Long linear performance warranty.
* ISO9001: 2008 Quality Management System certified factory.
* IEC, TUV, CE, ROHS, SONCAP, MCS, UL etc approval.
* Our high transmission glass features a unique-reflective coating that directs more light on the solar cells, resulting in a higher energy yield.
* Highly reliable due to stringent quality control measures, strict selection of raw materials &components and testing.
* Tested in accordance to the standard IEC 62804, our PV modules have demonstrated resistance against PID (Potential Induced Degradation), which translates to security for your investment.
25 Years Linear Performance Guarantee
For a period of twenty-five (25) years commencing on the warranty start date, loss of power output of the nominal power output measured at Standard Test Conditions (STC) for the product(s) shall not exceed:
* For Mono-crystalline Products: 3% in the first year, thereafter 0.67% per year, ending with 81% in the 25th year after the warranty start date. (the warranty start date shall be defined as the date of the Bill of Lading date).
Applications: They have been used for: home power lighting system; off-grid system, remote area stand-alone applications; on-grid residential/commercial rooftop& ground, large scale utility application and other power station.
