JA Solar launched its new n-type module DeepBlue 4.0 Pro at SNEC 2023. Based on a brand new dimension of next-generation rectangular silicon wafer, the module is capturing the eye of the business.
The module adapts cells reduce from the subsequent era n-type rectangular silicon wafer dimension independently developed by JA Solar that options lengthy lifespan and low oxygen content material. Combined with high-efficiency n-type passivation contact Bycium+ cell expertise, the Open Circuit Voltage (Voc) of the cell reaches 725mV and the cell effectivity of mass manufacturing reaches 25.3%.
As properly, DeepBlue 4.0 Pro integrates SMBB expertise, high-density encapsulation expertise, and different applied sciences enhancing high quality and effectivity, enabling the power of the 72-cell module to succeed in 630W with module effectivity exceeding 22.5%. Compared to the mainstream 182 collection 78-cell modules (2465mm x 1134mm) within the business, our power is best whereas lowering the working voltage of the brand new dimension by 7.6%, which decreases BOS price for the system and scorching spot danger for the modules.
The spotlight of DeepBlue 4.0 Pro is its 182mm x 199mm silicon wafers, which permits software beneath a number of situation. Different from different rectangular silicon wafer sizes, the 182mm x 199mm rectangular silicon wafer can preserve width of 1134mm whereas satisfying 4 mainstream size of modules: 1762mm, 2333mm, 2384mm and 2465mm via totally different slicing strategies. DeepBlue 4.0 Pro meets the calls for of various software eventualities, comparable to residential rooftop, industrial and industrial rooftop system and utility power vegetation.
Similar to earlier DeepBlue 4.0 X, DeepBlue 4.0 Pro has wonderful power era capability and dependable efficiency. Based on Bycium+ cell expertise, DeepBlue 4.0 Pro has excellent power era traits, comparable to decrease degradation, higher temperature coefficient, increased bifacial era acquire, and higher decrease irradiance efficiency.
Compared to standard p-type modules, one-year subject check outcomes from JA Solar and TÜV NORD confirmed that the n-type module with Bycium+ cell has a electrical energy era acquire about 3.9%, utterly proving its power era capability. Furthermore, DeepBlue 4.0 Pro has handed varied rigorous growing old assessments and all outcomes meet the testing necessities of IEC requirements.
The business already comprehensively accredited the power era efficiency, security efficiency, and reliability in varied software eventualities of DeepBlue 4.0 Pro. At the time of launch, this module had earned these vital certifications: the TÜV SÜD certificates from TÜV SÜD, the Salt mist corrosion certificates, Ammonia corrosion certificates and Dust and sand certificates from TÜV NORD, and Golden Sun Certificate for Photovoltaic Products, Photovoltaic Non-uniform Snow Load Reliability Certification and Photovoltaic Flexible Racking System Compatibility Certificate from CGC.
JA Solar’s product design philosophy is “tailored to increase customer value”, and the higher BOS price and LCOE of DeepBlue 4.0 Pro ship on this promise. Integrating benefits comparable to excessive effectivity, excessive power, higher power era capability and excessive reliability, DeepBlue 4.0 Pro can generate larger income for purchasers. When in comparison with p-type modules in several software eventualities, venture varieties and set up strategies, the BOS price of DeepBlue 4.0 Pro could be lowered by about 2%-4.5%, and the LCOE could be lowered by about 2.5%-6%. Compared to the unique model of the n-type module, the BOS price of DeepBlue 4.0 Pro could be lowered by about 1.4%-2.8%, and the LCOE could be lowered by about 0.7%-1.6%.
