  1. defects and/or failures due to manufacturing;
  2. defects and/or failures due to materials;
  3. cracking of the front glass surface due to foreign objects inside the glass; or Note: This limited warranty shall exclude cracking of the front glass surface due to external shock from flying objects or external stress.
  4. non-conformity with specifications due to faulty manufacturing and/or inspection processes.

If the PV Module(s) fails to conform with this warranty, BLS will repair the PV Module(s), or replace the PV Module(s) with equivalent PV Module(s), at BLS’s sole option.

Limited Power Output Warranty of 20 years (90% / 80%)

Subject to BLS determining in its sole discretion that any power loss is due solely to defects in materials or workmanship, BLS warrants the power output of each type of PV Module(s):

BLS warrants that if, (a) within the first ten (10) years from the date of sale to the Customer, the PV Module(s) exhibits a power output of less than ninety percent (90%) of the original minimum rated power specified at the time of sale*, or (b) within twenty (20) years from the date of sale to the Customer, the PV Module(s) exhibits a power output of less than eighty percent (80%) of the original minimum rated power specified at the time of sale*, BLS will deliver additional PV Module(s) to replace the missing power output, or repair the PV Module(s), or replace the PV Module(s) with equivalent PV Module(s), at BLS’s sole option. The period of the output warranty for these additional or replacement module(s) will be equal to the remainder of the warranty period of the originally supplied modules(s).

*The power output values shall be those measured under BLS’s standard measurement conditions as follows: (a) light spectrum of AM 1.5; (b) irradiation of 1,000w per m2; and (c) a cell temperature of 25 degrees Centigrade. Such measurements are carried out in accordance with IEC 60904 as tested at the junction box terminals per the calibration and testing standards of BLS which are valid at the date of manufacture of the PV Module(s). BLS’s calibration standards shall be compliant with the standards applied by international institutions accredited for this purpose.
