After few months of operations of its 1 GW manufacturing lines, the company has disclosed a few more details about the new product &#; the Tiger Neo solar module, which it is planning to launch on the market soon. &#;Having expanded the economies of scale makes it easier to compete with p-type PERC product,&#; JinkoSolar CTO, Hao Jin, told pv magazine.

The panel is made with 182mm wafers, half-cut cells, and has a power output ranging from 590 to 620 W. It measures ××30mm and has a weight of 34.8 kg. Its power conversion efficiency ranges from 21.11% and 22.18% and its temperature coefficient is -0.30% per Celsius degree.

The operating ambient temperature ranges from -40 to 85 degrees Celsius, said the manufacturer, and maximum system voltage is 1,500 V. The panel has an anodized aluminum frame and 2mm of tempered glass with an anti-reflection coating. Its junction box has an IP 68 rating.

Jinko offers a 15-year product warranty and a 30-year power output guarantee. Annual linear degradation over 30 years is indicated at 0.40% while degradation for the first year of the panel&#;s lifetime is capped at less than 1%.

&#;The module is manufactured with a circular solder strip to obtain better optical gain,&#; Jin went on to say. &#;Its bifaciality of 80-85% is about 5%-15% higher than that of conventional p-type bifacial products.&#; According to the manufacturer, the combination of advantages such as a low-temperature coefficient, a low degradation rate, and the high bifaciality ensure that the energy yield is 3% higher than that of mainstream p-type bifacial modules.

The module is recommended for utility-scale projects, but JinkoSolar said that, given its efficiency and reliability, it could also be used for rooftop projects of any size.

JinkoSolar had announced in mid-July it achieved a 23.53% conversion efficiency for an n-type monocrystalline solar PV module based on its TOPCon mono cell technology. &#;The module's breakthrough performance was the result of adopting JinkoSolar's cutting-edge TOPCon cell technology fused with a new-type of welding and packaging technology,&#; the manufacturer said in a statement released at the time. &#;The module design not only reduces the internal resistance loss of the module, but improves power efficiency and module appearance.&#;

SHANGRAO, China, November 2, &#; JinkoSolar Holding Co., Ltd. (the &#;Company&#;, or &#;JinkoSolar&#;) (NYSE: JKS), one of the largest and most innovative solar module manufacturers in the world, today announced that it has launched a new series of ultra-efficient Flagship Tiger Neo Modules.

The New Tiger Neo adopts N-type TOPCon technology with further enhancements in performance, power, energy density, and reliability. The new module delivers a maximum power output of up to 620W into mass production, with an ultra-high conversion efficiency of up to 22.30%.

Better Power Generation Performance

JinkoSolar&#;s N-type TOPCon technology provides about 5% to 6% more efficiency than mono PERC and about 3% to 4% more energy generation. Mass produced from 182mm wafers, the new Tiger Neo modules features Multi-Busbar (MBB) and half-cut cell technology to reduce internal resistance loss, and the circular solder strip design increases optical gain so that the module has an ultra-high efficiency of up to 22.30%.

Higher Bifacial Factor

Tiger Neo&#;s bifacial factor of up to 85% is a great advantage due to its 5% to 15% higher energy yield compared to conventional P-type bifacial modules in its life-time period. A higher bifacial factor also improves its power generation capacity and power generation efficiency.

Lower Degradation and Longer Warranty

Thanks to less LID and LeTID risks, JinkoSolar provides an industry-leading 30-year linear power output guarantee. The first-year degradation has been claimed to be less than 1% and power output is guaranteed to be no less than 87.40% of the nominal power output after 30 years.

Lower Temperature Coefficient

The Tiger Neo module has a lower temperature coefficient of -0.30% / &#; compared with -0.35% / &#; for the P-type, which makes it more durable to withstand extreme and high-temperature environment. Its low-light performance and small irradiance angle prolongs generation period of the panel during the day. Combining the advantages of low-temperature coefficient, low degradation, and high bifacial factor, annual energy yield is 3% higher than that of mainstream P-type bifacial modules.

With higher efficiency, higher bifacial factor, lower degradation, lower working temperatures and better low-irradiance performance, JinkoSolar&#;s leading N-type TOPCon technology is touted to be the industrial next-generation mainstream technology after the mono PERC. In regards to the N-type&#;s yield rates and manufacturing costs, JinkoSolar remains ahead of its competitors, thanks to its technical breakthroughs in process technology.

Mr. Kangping Chen, Chief Executive officer of JinkoSolar Co., Ltd., commented, &#;The global PV market is entering a new era of energy generation at an unprecedented speed. The need to address different energy application scenarios and the urgency of the government and various industries for energy transformation have pushed the solar power demand to a new level. The new Tiger Neo flagship series was designed to meet the needs of large-scale utility, industrial and commercial distributed generation, and residential applications. Through the advantages of the N-type TOPCon technology, customers can invest in more efficient, more reliable, and more profitable PV systems. We believe that the Tiger Neo modules will continue to set new industry standards, and further promote the development of the global solar industry so that more people can enjoy a brighter future driven by clean energy solutions.&#;
