On Wednesday, May 18, JA Solar launched its first n-type PV module DeepBlue 4.0 X. This innovative new product marks the company's entry into the n-type PV product market.
Made from 182 mm wafers, the DeepBlue 4.0 X series include three types of modules designed for different application scenarios. The 54-cell module for residential PV systems, and the 72-cell and 78-cell modules for commercial and utility-scale PV projects.
DeepBlue 4.0 X boasts high quality and reliability as it has passed the IEC 61215 and IEC 61730 tests and obtained the TÜV SÜD certificate. It has also passed the salt mist, ammonia, sand and dust testing, proving its versatility in different applications and environments.
In addition to the advantages carried over from DeepBlue 3.0 modules, DeepBlue 4.0 X integrates JA Solar’s latest technologies, including the Bycium+ cell with over 24.8% commercial efficiency.
DeepBlue 4.0 X is also equipped with the patented high-density module encapsulation technology gapless flexible interconnection (GFI). The design of the round ribbon with buffer treatment and optimized encapsulation material can reduce mechanical stress at cell interconnections and thus eliminate the risk of micro-cracking.
These technologies together can bring higher reliability and energy yield for DeepBlue 4.0 X, whose maximum power could reach 625W and up to 22.4% conversion efficiency.
Kun Tang, Director of the Product Technology Department at JA Solar, said that JA Solar has been working on the n-type technology for years. After continuous investment in R&D and experiments, the company is finally ready for mass production.
To verify the performance of the product, JA Solar and TÜV NORD launched a one-year energy yield test in February 2021 at China Photovoltaic Test Center, Yinchuan base. 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, commented that, "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."
