JA Solar unveils its first n type module with DeepBlue 4.0 X

JA Solar new product DeepBlue 4.0 X

At its product launch event on May 18, JA Solar released its first n-type PV module: the DeepBlue 4.0 X. Based on the 182 wafer, the DeepBlue 4.0 X series includes three module types: 54-cell module for residential PV systems, 72-cell and 78-cell for commercial and utility-scale PV projects.

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.

DeepBlue 4.0 X has already passed the IEC 61215 and IEC 61730 tests and obtained the TÜV SÜD certificate, as well as passed the salt mist, ammonia, sand and dust testing, proving its suitability across various applications and environments.

DeepBlue 4.0 X builds on the DeepBlue 3.0 advances, but 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). The design of the round ribbon with buffer treatment and optimized encapsulation material deals with mechanical stress at cell interconnections to eliminate the risk of micro-cracking, the company says.

Together, DeepBlue 4.0 X is said to have a maximum power reaching 625W and efficiency of up to 22.4%.

To verify the power generation performance of the product, JA Solar and TÜV 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%.

“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’,” stated Xinwei Niu, Member of the Board and Senior Vice President of JA Solar.. “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.”
