Photovoltaic company JA Solar has released its latest n-type module, the DeepBlue 4.0 Pro, which is based on a new size of next-generation rectangular silicon wafer.
The module adapts cells cut from the silicon wafer size that was independently developed by JA Solar and features a long lifespan and low oxygen content. Combined with high-efficiency n-type passivation contact Bycium+ cell technology, the open-circuit voltage (Voc) of the cell reaches 725mV and the cell efficiency of mass production reaches 25.3 per cent.
The DeepBlue 4.0 Pro integrates Super Multi BusBar (SMBB) and high-density encapsulation technology to improve quality and efficiency, enabling the power of the 72-cell module to reach 630W, with module efficiency exceeding 22.5 per cent.
The module delivers on power and reduces the working voltage of the new dimension by 7.6 per cent, which decreases balance-of-system cost – which can be reduced by two per cent to 4.5 per cent – and hot-spot risk.
The 182mm x 199mm silicon wafers can keep a width of 1134mm while satisfying four mainstream module lengths: 1762mm, 2333mm, 2384mm and 2465mm through different cutting methods.
The DeepBlue 4.0 Pro can meet the demands of residential rooftop, commercial and industrial rooftop systems, as well as utility power plants.
Based on Bycium+ cell technology, DeepBlue 4.0 Pro has outstanding power generation, low degradation, improved temperature coefficient, high bifacial generation gain, and lower irradiance performance.
Compared to conventional p-type modules, one-year field test results from JA Solar and international certification company TÜV NORD demonstrate this n-type module has an electricity generation gain of 3.9 per cent. It has also passed rigorous ageing tests, meeting the requirements of International Electrotechnical Commission (IEC) standards.
JA Solar’s product design philosophy is “tailored to increase customer value”. The DeepBlue 4.0 Pro delivers on this promise, with its high efficiency, high power, large power generation capacity and reliability.
Compared to p-type modules in different application scenarios, project types and installation methods, the levelised cost of energy (LCOE) cost of DeepBlue 4.0 Pro can be reduced by 2.5 per cent to six per cent. Compared to the original version of the n-type module, the BOS cost of DeepBlue 4.0 Pro can be reduced by 1.4 per cent to 2.8 per cent, and LCOE can be reduced by 0.7 per cent to 1.6 per cent.
