JA Solar celebrates its 2022 new product launch event on May 18, with the 
release of its first n-type PV module DeepBlue 4.0 X. This innovative new 
product offering marks the company's first entry into the n-type PV product 
market.

Based on the 182 wafer, which boasts the most mature supply chain and 
industry-wide recognition, the DeepBlue 4.0 X series includes three module 
types adaptable to any scenario: 54-cell module for residential PV systems, 
72-cell and 78-cell for commercial and utility-scale PV projects. DeepBlue 4.0 
X has already passed the IEC 61215 and IEC 61730 tests and obtained the TUV SUD 
certificate, as well as passed the salt mist, ammonia, sand and dust testing, 
proving its suitability across various applications and environments.

In addition to the advantages carried over from DeepBlue 3.0 modules, DeepBlue 
4.0 X integrates the latest technologies from JA Solar, including the Bycium+ 
cell, wherein mass production efficiency can reach more than 24.8% owing to its 
high-quality substrate and structure. Also, DeepBlue 4.0 X is equipped with the 
patented high-density module encapsulation technology GFI (Gapless flexible 
interconnection),  where the design of the round ribbon with buffer treatment 
and optimized encapsulation material deals with mechanical stress at cell 
interconnections and thus eliminating the risk of micro-cracking. Together, 
these bring higher reliability and higher energy yield to DeepBlue 4.0 X, with 
maximum power reaching 625W and efficiency of up to 22.4%. 

According to Kun Tang, Director of the Product Technology Department at JA 
Solar, JA Solar has been working on the n-type technology for years, and after 
continuous investment in R&D and experimentation, is finally ready for mass 
production. To verify the power generation performance of the product, JA Solar 
and TUV NORD launched a one-year (February 2021-February 2022) energy yield 
test at China Photovoltaic Test Center, Yinchuan base (Northwest  China). The 
results show that the energy yield of the n-type module based on Bycium+ cells 
is 3.9% higher than that of p-PERC modules. According to JA Solar PV system 
simulation data, compared with p-type modules, BOS cost reduction of DeepBlue 
4.0 X tops out at 2.1%, and LCOE at 4.6%, further increasing the IRR and 
bringing more value to the customer.

Mr. Xinwei Niu, Member of the Board and Senior Vice President of JA Solar, 
said, "The development of low-carbon and green solutions has become a key 
global mission. As one of the most flexible and cost-effective renewable 
energy, PV power has become an important force in promoting carbon neutrality. 
From p-type to n-type, from DeepBlue 3.0 to DeepBlue 4.0 X, JA Solar has always 
adhered to the product design concept of 'customer oriented'. We are always 
trying to improve the power generation performance of PV modules in order to 
create more value for customers and promote the application of PV power at a 
global scale to play a greater role in the process of global carbon neutrality."
