Quality makes us who we are today

Our No.1 ranking in shipments for three consecutive years and our solid track record speak for itself. As a leading module manufacturer, JinkoSolar has shipped approximately 40GW of solar modules to customers in 108 countries around the globe. Jinko has been recognized by DNV GL as the “Top Performer” among global PV module manufacturers for the fifth time in 2019.


High efficiency, reliability and safety consists three pillars of what we called "Quality"

Our entire production process is closely monitored. Every cell and module is subjected to at least 36 steps of the most stringent quality inspection procedures and undergoes comprehensive in-house testing in the most advanced UL certified testing lab. It tests its products under extreme conditions such as tropical humidity, desert heat, coastal salt mist or agricultural ammonia enveloped atmosphere.


JinkoSolar has been awarded Best Performer in Photon Lab Module Test for consecutive years. We are also the first Company to pass as PID-Free under 65℃/85% RH, and the first company to withstand a PID-Free test under 65℃/85% RH for 1000 hours. And we have one of the lowest defect and claim rates in the industry.


Powered plant is expected to work for at least 25 years no matter where and under what condition it sits and what challenge it will meet over 1/4 century , therefore it must live up to the highest quality standards. This is why JinkoSolar maintains one of the highest industrial standards for the design, performance, and workmanship of its solar products to secure a reliable energy supply of the PV system for well over 25 years.

Warranted Performance in Real-World Conditions

All above factors combined to enable JinkoSolar panels of best and warranted generating capability and performance in the real world condition which was solidly proven by 2019 Photon Lab Field Module Test Result. It showed:


JinkoSolar panels perform better at high temperatures and high humidity environment than others thanks to its PID free features.

JinkoSolar panel outperform in harsh nature condition including frequent typhoon, earthquake, snow and wind, coast-nearby, ammonia enveloped farm etc. due to its superiors mechanical a well as chemical stress resistant features.

JinkoSolar panels generate more electricity in early in the morning, late in the day, and on cloudy days resulted from its cutting edge solar wafer and cell technology.

One of the lowest light-induced-degradation being exposed in sunlight ensures reliable output over time.

Advantages for customers

Dependable system performance due to comprehensive approval certification.

High yields over the long run and high investment security due to stringent reliability and safety tests.

Strong power generation in a given time and space because of the high efficiency of the solar cells.

Consistent performance and durability after exposure to intense sunlight and in extreme conditions.

Less O&M needed due to quality of materials used.
