JA Solar Debuts n-type PV module DeepBlue 4.0 X Series with Three Types

JA Solar has launched its first n-type n-type PV module DeepBlue 4.0 X. Based on the 182 Wafer, the DeepBlue series 4.0 X includes three module types that are adaptable to any situation: a 54-cell module suitable for residential PV systems, and a 72-cell or 78-cell module suitable 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.

DeepBlue 4.0 X incorporates the same advantages as DeepBlue 3.0 modules. It also includes the latest technologies from JA Solar including the Bycium+ cells. This high-quality structure and substrate allows for mass production efficiency of more than 24.8%. DeepBlue 4.0X features the patented high density module-encapsulation technology GFI. This technology uses a round ribbon with buffer and optimized encapsulation materials to reduce mechanical stress at interconnections, eliminating the possibility of micro-cracking. These combine to give DeepBlue 4.0X a higher reliability and greater energy yield. The maximum power output is 625W, and an efficiency of up 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 TÜV NORD launched a one-year (February 2021-February 2022) energy yield test at China Photovoltaic Test Center, Yinchuan base (Northwest China). The results showed that the n-type module based upon Bycium+ cells has a 3.9% higher energy yield than p-PERC. According to JA Solar PV simulation data, the BOS cost reduction of DeepBlue 4.0 X is 2.1% and LCOE at 4.6% respectively, which increases the IRR and brings more value to the customer. “The development of low-carbon and green solutions has become a key global mission,” says Xinwei Niu, member of the board and senior vice president of JA Solar.

“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.”
