On October 11, LONGi grandly released HPBC2.0 technology platform and a new generation of distributed module product - Hi-MO X10 at the ATP Shanghai Rolex Masters, marking the release of the preferred high-value module product for the whole scenario of the global distributed market.

Hi-MO X10 module is a high-quality module based on the cross-generation HPBC2.0 battery technology, with leading power generation performance, reliability, customer benefits and aesthetics, with the highest mass-produced power of 670W, which is more than 30W higher than that of the industry's TOPCon mainstream module, and mass-produced module efficiency of 24.8%, which is another breakthrough of the world's highest record of mass-produced module efficiency. Adopting HPBC2.0 battery, the mass production efficiency of the battery is more than 26.6%, which is the last generation of crystalline silicon battery to realize the absolute efficiency of 1% across the battery technology, announcing that the BC era has really come.

Product Highlights

With the heavy release of Hi-MO X10, its four highlighted product highlights have also officially surfaced: HPBC2.0, TaiRay Core, 0BB technology and advanced module technology.

LONGi's HPBC2.0 battery technology can be regarded as a masterpiece of BC battery technology. 2022 November, LONGi successfully released the revolutionary HPBC1.0 battery technology, officially opening the BC era. Two years later, LONGi's HPBC2.0 battery technology inherits the excellent genes of the HPBC generation, crosses the three key technological gaps of battery substrate, passivation technology and process technology, and is the battery technology with the highest mass production efficiency in the world. It took LONGi only two years to realize a leap of 1.5% in absolute value and open a generation-level gap with mainstream market general-purpose batteries.

At the same time, HPBC2.0 breaks the battery technology barriers and self-developed bipolar composite passivation technology, which makes the open circuit voltage of mass-produced batteries break through 745 mV, significantly reduces the current loss, and improves the conversion efficiency of batteries.

The new product is equipped with TaiRay “core”, i.e. high-quality N-type TaiRay silicon wafers, realizing a substantial innovative breakthrough in the field of silicon wafers in the past decade, with three significant advantages: first, in the case of consistent rod length, the resistivity ratio of the output of crystalline rods at the head and tail of the rod has been reduced from 3 times to less than 1.5 times, with a more centralized resistivity and high consistency of the wafers, reducing the risk of mismatch; second, the resistance ratio of the output of crystalline rods is reduced from 3 times to less than 1.5 times. Secondly, metal impurities in TaiRay silicon wafers are more easily absorbed, reducing current loss and effectively enhancing power generation potential; thirdly, the mechanical properties are stronger, and the mechanical strength is increased by 16% compared with conventional products, making them tougher and more reliable.

LONGi's new module also further adopts the innovative 0BB structure, which further realizes “no main grid on the back” on the basis of “no grid on the front”. This “king bomb” combination not only maximizes the area of light absorption on the front side, but also significantly improves the efficiency of light absorption and reflection on the back side. Adopting 0BB structure, after removing the main grid, the thin grid is directly connected to the welding tape, shortening the current transmission distance and further increasing the module power by 5W+. At the same time, it also makes the aesthetics of the back side of the cell further optimized, and effectively improves the double-sided rate of the cell, which provides more potential space for double-sided cell and module products.

Product Advantages

More Secure

The unique bypass-like diode structure of Hi-MO X10 module enables the blocked current to bypass the blocked area and divert the current from other paths without affecting the power output of the whole string of cells when encountering shadow blockage, reducing the power loss of the module by more than 70% compared with TOPCon products. At the same time, it can greatly reduce the hot spot temperature under the shadow blockage, preventing localized overheating, reducing the temperature by 28%+ compared to conventional batteries, not fearing high temperatures, and guaranteeing the robust operation of the module and the safety of the rooftop.

UV irradiation, high temperature and humidity, and alternating cycles of heat and cold also pose challenges to the robust operation of the modules during the long “service” period. Hi-MO X10 modules, with low operating temperatures and high-density encapsulation, have “comprehensive anti-aging” performance, and their performance is excellent under the rigorous tests. Hi-MO X10 modules have excellent performance under severe testing. Compared with TOPCon modules, Hi-MO X10 has better UV resistance, humidity resistance and thermal cycling resistance, and is more resistant to heat, humidity and sunlight. Its power temperature coefficient is -0.26%/°C, optimized by 0.03%/°C compared with TOPCon; 1% attenuation in the first year, 0.35% linear attenuation, long-lasting and strong, and it can provide customers with up to 15 years of product warranty and 30 years of power warranty.

Hi-MO X10 modules also have system-level impact resistance and anti-cracking performance. First of all, thanks to the super mechanical properties of TaiRay silicon wafers, when silicon wafers tend to be more and more close to the background of thin film, LONGi still adhere to the bottom line of the industry, TaiRay silicon wafers are still thicker than the mainstream products in the market. Secondly, the full back of the “a” type welding structure, significantly reducing the hidden crack risk of components in the process of transportation, installation and “service”. Comprehensive logistics and transportation data show that the overall hidden crack risk is reduced by as much as 87.2%, and customers can rest assured that they are not afraid of multiple environmental stresses.

High Yield

Based on the current mainstream version (2382×1134mm), with the module cost of $0.8/Wp, Hi-MO X10 module can increase the total profit by 9.1% compared with the mainstream TOPCon module in terms of 25-year total profit. This means that for two PV power stations under the same conditions, the mainstream TOPCon modules need to be installed with 231 more modules to achieve the same level of total profit as Hi-MO X10 modules, i.e. about 24.2 million RMB. At the same time, the project investment must be increased by 263,400 RMB, and the cost per watt increased by 27.1 cents.

From the 25-year yield dimension, the IRR of Hi-MO X10 module is 6.2% higher than that of TOPCon. This means that for two PV power stations under the same conditions, the mainstream TOPCon has to be cheaper by 13.1 cents to achieve the same 25-year full investment yield as Hi-MO X10, i.e. 30.71%.

In terms of payback cycle, Hi-MO X10 can realize a faster payback cycle, which is 0.2 years shorter than that of TOPCon. This means that under the same conditions of the two PV power plants, the mainstream TOPCon to achieve and Hi-MO X10 the same payback cycle (3.25 years), mainstream TOPCon module than Hi-MO X10 monowatt price is cheaper than 13.1 cents in order to realize.

Looking at the 25-year electricity cost again, Hi-MO X10 is 5.1% lower than mainstream TOPCon. This means that under the same conditions of the two PV power stations, the mainstream TOPCon to achieve and Hi-MO X10 the same 25 annual cost of electricity (LCOE = 0.094 yuan / degree), the mainstream TOPCon module needs to be cheaper than the Hi-MO X10 single watt price of 15.1 cents to achieve.

Finally, there is the $10,000 net profit investment, and the $10,000 net profit investment of Hi-MO X10 is 6.1% lower than that of mainstream TOPCon modules. This means that for two PV plants under the same conditions, assuming the same 25-year period to obtain $10,000 net profit, mainstream TOPCon modules need to be 15 cents lower than Hi-MO X10's unit-watt price to realize it.

Extreme Beauty

Facing the increasingly diversified application scenarios in the distributed market, LONGi has always been customer-focused to meet the ever-changing market demand, enriching the product matrix from multiple dimensions such as efficiency, functionality, reliability, weather resistance, aesthetics, etc., so as to match the differentiated needs of more segmented areas, realize the high-quality simultaneous development of both the production end and the application end, and lead the technological innovation of photovoltaic modules.

Since the second half of 2023, LONGi has intensively launched a number of module products suitable for different application scenarios. These include the Hi-MO X6 single-glass anti-dust accumulation module released in October 2023 for large-scale industrial and commercial scenarios, the Hi-MO X6 double-glass hygrothermal-resistant module released in February 2024 for high-temperature and high-humidity scenarios around the globe, the Hi-MO X6 Max based on the mainstream version released in LONGi's Jiaxing lighthouse factory in May 2024, and the Hi-MO X6 villa model module released in the SNEC exhibition in June 2024, as well as the Hi-MO X6 Villa model module released at the LONGi PV PV Pavilion. Hi-MO X6 villa model components, etc. Meanwhile, in terms of artistry, LONGi also seeks to change the stereotypical impression of PV modules as “plastered and patched” in the past, and push the aesthetics of the modules to the extreme. Whether it is the all-black and ultimate black products launched for the global market or the villa model modules launched for the Chinese market, they have all gained popularity in the market after their launch, especially in the household market in Europe, Asia-Pacific, Japan and China.

Hi-MO X10 module continues the excellent gene of Hi-MO series products family, and continues the previous product hierarchical grading system to meet the personalized needs of customers based on different application scenarios.Hi-MO X10 module continues the design concept of “simplifying complexity into simplicity”, and further realizes the design of no main grille on the back on the basis of no grille on the front side. On the basis of the previous design with no grill line on the front, it further realizes the design with no main grill on the back, which creates a pure and advanced appearance of the module and defines the minimalist beauty of the BC module, which can match different architectural styles with harmony and elegance, and honors a green and low-carbon quality of life. Enhancing the color value of modules is not only LONGi's ultimate pursuit of aesthetics of PV products, but also an opportunity to open up new growth points in the distributed PV market, promote the application of PV power generation in more scenarios, and help realize the goal of “double carbon”.

Hello, readers! In this blog post, I'm thrilled to delve into the intricate and fascinating world of photovoltaic (PV) module manufacturing. As renewable energy sources gain prominence globally, understanding the production process of PV modules becomes increasingly important. These modules, the building blocks of solar energy systems, undergo a meticulous series of steps to transform sunlight into electricity. Let's embark on this journey together!

Introduction to Photovoltaic Modules

Photovoltaic modules, commonly known as solar panels, are devices that convert sunlight directly into electricity through the photovoltaic effect. They consist of multiple layers, including photovoltaic cells (typically made from silicon), protective glass, encapsulants, and a backing sheet, all encased in a sturdy frame. The production of these modules involves a blend of advanced technology, precision engineering, and rigorous quality control.

Production Process Overview

The production of PV modules begins with raw materials and ends with a fully assembled, ready-to-install product. Here's a detailed breakdown of the key steps:

1. Cell Sorting and Selection

The journey starts with the sorting and selection of photovoltaic cells. Since the performance of individual cells can vary, it's crucial to group cells with similar electrical characteristics (such as current and voltage output) together. This ensures optimal performance and efficiency of the final module. Advanced testing equipment is used to measure and classify the cells accurately.

2. Laser Scribing and Cutting (Optional Half-Cut Technology)

Next, selected cells undergo laser scribing, a precise process that uses high-powered lasers to cut the cells into smaller, manageable pieces. This step, known as half-cut technology, has gained popularity due to its ability to reduce resistance losses and improve module efficiency. The laser cuts the cells cleanly, minimizing damage to the delicate surface coatings.

3. Tabbing and Stringing

After cutting, the individual cells are connected using thin metal strips called tabs. These tabs are soldered to the cells, forming electrical connections. Then, the tabbed cells are arranged in series and interconnected with thicker wires, creating strings of cells. This step, known as stringing, establishes the initial current path within the module.

4. Layering and Assembly

The strings of cells are then carefully layered with other components, including tempered glass, encapsulant (usually EVA), and a backing sheet. The layers are stacked in a specific order (glass, EVA, cells, EVA, backing sheet) to ensure optimal light transmission and protection. This assembly process requires precision to maintain the alignment and spacing of the cells.

5. Electrical and Visual Inspection (EL Testing)

Before proceeding to the next step, the assembled modules undergo rigorous electrical and visual inspections. Electroluminescence (EL) testing, a non-destructive method, is used to identify any internal defects such as cracks, breaks, or hotspots in the cells. This ensures that only flawless modules proceed to the next stage.

6. Lamination (Layer Pressing)

The assembled layers are then fed into a lamination machine, where they are subjected to high heat and pressure. This process melts the EVA encapsulant, bonding the layers together into a single, sturdy unit. The resulting laminate is cooled and trimmed to remove excess material, ensuring a clean and professional appearance.

7. Framing and Bordering

To enhance structural integrity and provide additional protection, an aluminum frame is attached to the perimeter of the laminated module. This frame also serves to seal the electrical connections, preventing moisture ingress and prolonging the module's lifespan.

8. Junction Box Installation

A junction box, designed to be waterproof and dustproof, is attached to the back of the module. This box houses the electrical connections, allowing for easy integration with the rest of the solar system. The box is filled with a sealing gel to ensure long-term protection against environmental elements.

9. Final Testing and Quality Control

Before leaving the factory, each module undergoes a series of final tests, including IV (current-voltage) testing and insulation/voltage resistance testing. These tests verify the module's performance, efficiency, and safety, ensuring that only the highest quality products reach the market.

10. Packaging and Shipping

Finally, the modules are carefully packaged to prevent damage during transportation. They are then shipped to customers worldwide, ready to be installed and generate clean, renewable energy.

Conclusion

The production of photovoltaic modules is a complex yet highly rewarding process. It combines cutting-edge technology, precision engineering, and rigorous quality control to create reliable and efficient solar energy solutions. As we continue to transition towards a more sustainable future, understanding the intricacies of PV module manufacturing becomes increasingly important. I hope this blog post has provided you with a comprehensive insight into this fascinating industry. Stay tuned for more updates on renewable energy and sustainable technologies!

3) Why switch size?

LONGi has always taken customer value as the core, and after gaining insights and conducting in-depth research on the needs of customers in the distributed business, LONGi found that different module and cell sizes in the industry would increase the cost and risk of the upstream and downstream industry chains. In order to better serve our customers, reduce their costs and increase their revenues, LONGi, together with eight leading PV companies (JinkoSolar, JA Solar, Trina Solar, GCL, TONGWEI, Astronergy,Risen Energy, and Together with DAS Solar), reached an agreement to standardize the size of the 72-version modules (2,382*1,134mm) and the size of the M11 wafers (191.6*182.2mm) by the end of the Q3 of 2023. 191.6*182.2mm standardization unification agreement, is the result of collective decision-making and joint professional research and judgment. Finally, on May 23, 2024, LONGi released Hi-MO X6 Max, a standardized module product based on M11 wafers and 2382*1134mm size switching, and effectively promoted the synergy of production, supply and marketing, and started the switching in Q2 2024, and completed the upgrading of all the mainstream products in Q3 24 years.

4) What are the benefits brought by the switchover?

1. Higher power generation:

Taking the 72 version as an example, compared with the same module specification products of friends using 210R wafers, Hi-MO X6 Max module products using M11 wafers have lower current, which can effectively reduce current transmission cable loss by 9%, and enhance power generation gain by 0.1%.

2. Lower cost

Lower transportation cost: Taking the 72 version as an example, the container utilization rate of Hi-MO X6 Max module reaches 98.5%, which is 4.4% higher than that of M10, and can effectively reduce the transportation cost by about 0.44 cents/W.

System Cost Reduction: Take the 72 version as an example, under the same roof area, the BOS cost at the installation end of the system is reduced by 3.57% (about 3 cents/W).
