Details

 


The good weak light performance(morning,evening and cloudy day) has been tested and approved by professional third-party.

 


Guarantee from ±3% as power tolerance.

 

 


100% EL test before and after lamination, and finished products EL test, providing higher quality assurance.

 

 

 


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:

 

1.Within a period of one (1) year from the Warranty Start Date, the module output will be at least 97% of the rated power output specified in the original product label.

 

2.During the next twenty-five (25) years, the module power output will degrade no  more than  0.708% per  year  of the  rated power output  specified in  the  original product label. Therefore,  at the end of  the warranty period, the guaranteed  module power outputwill be  at least 80.008% of the rated  power output specified in  the original product label.
