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 TÜV SÜD 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%.
