DuPont Global Field Reliability Program
JinkoSolar has a strategic relationship with DuPont™️, the inventor of Kevlar, to incorporate its strong, durable Tedlar®️ material into its EAGLE Modules backsheets. Tedlar®️ is the only material proven to last more than 30 years in the field. Because backsheet failures represent a large problem in the field, many customers buy from JinkoSolar due to the proven materials used. Since 2011, DuPont™️ has been conducting worldwide field surveys to inspect, assess, and understand the state of degradation of PV modules with varying ages, bill of materials, and in a variety of geographies and climates all over the world. This survey included:
13m+
modules
630+
installations
4GW
Total Power
Typical Backsheet Field Failure Mode
pa backsheet
Backsheet Cracking
After 3-4 years
pvdf backsheet
Outer Layer Cracking
After 6-7 years
PET Backsheet
Inner Layer Cracking
After 3-4 years
PVDF Backsheet
Inner Layer Cracking
After 3-4 years

Field Proven Cases of Tedlar Backsheet
Glass + Backsheet Structure = 40+ Years Field Proven
Breathable backsheet allows moisture and gases from encapsulant degradation to be released out of module
monofacial module
40yrs+ field proven record
bifacial module
Same module structure
Same manufacturing process
Same BOS and installation
3.2mm Fully Tempered Glass = Better Hail Resistance
jinkosolar
3.2mm fully tempered glass
Hail resistance up to 55mm hailstone
other manufaturers
2.0mm Heat Strengthened Glass
Many 2.0 modules only pass up to 45mm hailstone resistance test,
while others have failed
