In the design, due to the denser main grid of the battery, the surface shielding of the battery is reduced, the light receiving area is increased, and the current conduction distance on the fine grid is shortened, thereby reducing the series resistance of the component, reducing the resistance loss, and improving the output of the component. power. In addition, this module has better low-light characteristics, and the possibility of forming ultra-low thermal resistance. In terms of manufacturing process, extremely low solder tape sealing loss, multi-main grid low-resistance copper wire packaging, shorter bus distance, and reduced heat loss; circular conductor structure replaces planar solder tape, forming secondary reflection, increasing incident luminous flux, in actual power generation The effect of light incidence at different angles in the middle is better; its horizontal (multi-fine grid) vertical (multi-fine welding wire) surface matching makes the appearance of the battery and components more delicate, detailed and beautiful.
Since the resistance to power generation per unit area exceeds conventional single crystal components by 10-15%, it can effectively reduce the system BOS cost and greatly increase the space utilization rate. It will be the best new choice for residential and industrial and commercial distribution.
Jinko's 310-watt single crystal PERC will squeeze the ordinary single crystal market
JinkoSolar has successfully increased the mass output power of 60 single-crystal PERC modules to 310 watts, once again squeezing the mainstream ordinary single-crystal 290-watt market, and once again breaking the industry single-crystal power standard to 300. Stepping above the tile.
Jinko Develops improved backside passivation battery technology to further reduce the backside recombination rate and achieve overall backside passivation. It can increase the efficiency of single crystal batteries by 1% or even 1.2%, and has room for further improvement, or may become the next generation industry The mainstream of efficient single crystal products in the era of 'super leader'.
The future development of photovoltaic technology still depends on the potential for cost reduction and efficiency increase. After several decades of development, there has been no fundamental breakthrough in single crystal technology. In the past two years, diamond wire cutting has been promoted to shorten the cost performance of polycrystalline, but the potential has also been exhausted. Jinko is promoting large-scale diamond wire cutting matching black silicon velvet and single crystal PERC battery technology on a large scale, which will simultaneously lead single polycrystalline products to reduce costs and improve efficiency. Constantly pursuing cost reduction and efficiency improvement, reducing the cost of photovoltaic power generation is the eternal theme of the photovoltaic industry. JinkoSolar continues to innovate and research and develop, as soon as possible, to enable photovoltaic power generation to achieve grid parity on the power generation side. By then, it can enter thousands of households like coal and hydropower today.
Cut in half to make it more efficient-the power of Jinko's 60 single crystals is comparable to ordinary 72
'Either the highest power or the best cost performance', 'The photovoltaic system is like running a marathon, testing both explosive power and endurance. Explosive power is the power of the module, and endurance is the attenuation.' This is the routine of the photovoltaic industry, and as the world’s largest module manufacturer, the crystal Ke Energy seems to know this. Jinkotec, which rarely participates in industry technology debates, changed its low-key style in the past and brought its six new products to the public to define the technology. Among them, the PERC monocrystalline half-chip module (Libra PERC Mono 60) is particularly eye-catching. It uses low-resistance half-cell battery module technology to reduce thermal resistance and increase output power, thereby reducing system losses. The maximum power of the 60-chip module is 320W, which is about 15 watts higher than the highest 305-watt half-chip module of the same kind in the industry, which is comparable to the ordinary 72-chip module. With the explosive power of natural advantages, there must be endurance. Jinko’s half-chip component products use low light attenuation PERC and low loss connection technology. Both the initial light attenuation and the average attenuation rate are lower than ordinary single crystals, while improving Voc and The actual power generation of the modules, and the further improved temperature coefficient, the accumulation of various factors, ensure the long-term power generation advantages of the system, and allow customers to have higher returns during the operating cycle.
With the gradual increase in the proportion of residential and industrial and commercial distributed power stations, higher efficiency and lower attenuation of component products can produce higher power per unit area, and only technology does not have to succumb to the times.
Jinko Poly 285 is here, the technology is not the best, only better
The 60 pieces of black silicon 285-watt components launched by JinkoSolar on SNEC indicate that the polycrystalline diamond wire cutting and matching black silicon texturing technology is becoming more and more perfect, and large-scale volume is about to be released. Compared with conventional silicon wafer products, the conversion efficiency of black silicon wafers can be increased by 0.2%-0.4%, and the output power of polycrystalline modules is increased by about 5 watts. As the unit output increases, the consumption of auxiliary materials decreases, and the price difference between single crystal and single crystal increases further. Adding 0.4% black silicon velvet gain, cost reduction and efficiency and low light attenuation advantages are reflected in this 285 watt (60 pieces) product.
Calculated according to the ratio, the cost of multi-crystalline electricity drops by 1 cent, and the entire crystalline silicon photovoltaic industry can reduce the cost of electricity by about 8 cents. Its market influence and driving force are unmatched by other technical routes, which is why it is affected by the global Polycrystalline, which is favored by financing, will continue to occupy more than 80% of the market. Jinko Energy's diamond wire cutting matches black silicon wool, which will lead the industry to reduce the cost and improve the efficiency of ultra-large-scale, high-efficiency, high-reliability polycrystalline products.
Will diamond wire cutting + black silicon become the terminator of ordinary diamond wire cutting single crystal? The technology has never stopped, Jinko has been working hard.
Jinko 310W N-type double-sided module-the first choice for installation in snowy areas
JinkoSolar also launched a 310-watt output N-type bifacial module (Gemini N-type bificial 60) at the SNEC exhibition. As the name implies, the bifacial module is able to generate electricity on both the front and back sides. It is encapsulated between two layers of glass, so that the module can absorb light energy on the front side to generate electricity, and the back side of the module can also absorb ground reflection light and atmospheric scattered light to generate additional power. Therefore, the module is suitable for areas with strong reflected light and scattered light on the ground and surrounding buildings to maximize the power generation on the front and back of the module. According to different ground reflectivity, the back reflection of the double-sided module contributes 10% to 30% of the actual power generation gain.
Superimposed with N-type double-sided single crystal and double glass technology, the front power of 60 N-type double-sided components can reach 310 watts, plus the back side absorbs reflected and scattered light gains, and the equivalent power can reach up to 400 watts (+30% ). The ability of the back to absorb oblique light allows the component to make a greater contribution to the power generation than traditional products in the early morning, evening and other non-direct sunlight situations. The sturdy double-glazed structure not only greatly improves the corrosion resistance and PID resistance of the module. This double-glazed structure with high double-sided high-efficiency power generation characteristics and excellent weather resistance is a high-latitude, snow-laden, sooner or later It is the first choice for installation in northern areas with large temperature difference between winter and summer. At the same time, it is also suitable for painting white paint or light gray ground. Its ultra-thin double glass structure makes the battery board beautiful and generous. It can also use its light transmittance to be installed on the roof, fence, complementary fishing light, complementary agricultural light, Building integration and distributed power generation systems such as agricultural canopies.
