Industry benchmark! 600W+ highly reliable and ultra-high power modules lead the photovoltaic 6.0 era!

After the "Double Carbon" goal was put forward, the development of wind power and photovoltaics has accelerated significantly. In the just-concluded National People's Congress, the government work report once again proposed that carbon peaking and carbon neutralization should be promoted in an orderly manner, and the construction of a new power system should be accelerated. The peak carbon neutralization work has been written into the government work report for two consecutive years. As the main force of renewable energy and a key part of building a new power system, photovoltaic power generation will play the role of "stabilizer" and "ballast stone" for energy supply.

Speeding up the development is an important task. How to ensure the coexistence of quality and quality of photovoltaic modules, Trina Solar is more cautious in opening up and innovating all the way: "One standard and five strict" limit testing sets the industry benchmark, 600W+ ultra-high power modules fully lead the photovoltaic 6.0 era, While ensuring the safe and reliable supply of electricity, we will promote low-carbon energy transformation.

Limit test verification

600W+ withstand extreme weather

In the actual use of photovoltaic modules outdoors, the load pressure and test mainly come from extreme climates such as blizzard and strong wind. In order to protect the interests of customers, the design of components needs to consider the ability to withstand extreme weather throughout the life cycle.

For self-verification, since last year, Trina Solar has organized six tests of "one standard and five strictness", namely a standard static load test as well as uneven snow load, extreme low temperature load, hail impact, multiple dynamic mechanical load, wind Five stricter tests including the tunnel limit wind speed test were conducted, and the "White Paper on Mechanical Reliability of 670W Extreme Modules" was published in a volume, which is open to the whole industry to share the research results and contribute to common progress.

For example, the uneven snow load test should be as close to reality as possible to simulate the uneven pressure caused by heavy snowfall on the surface of the module, especially the bottom end. Under the condition of the ultimate pressure of 7000Pa, it is equivalent to 2.8 meters of snow, and the power of the 670W Supreme module is reduced Only 0.56%; in the wind tunnel limit wind speed test, when the wind speed reaches 62 m/s, the 670W Extreme module is still in good condition, passing the limit wind speed test equivalent to the super strong wind of level 17; the hail impact test simulates the impact of hail of different sizes on photovoltaics The shock of the components, the final 670W Supreme components were impacted by 35mm hail.

Innovative technology design

600W+ mechanical performance upgrade

Technological changes and product upgrading are inevitable for all industries and any industry. Finding key variables and adapting to new needs and new developments is the most critical and most valuable. Just like a steel aircraft carrier can travel farther and is more solid and reliable than a wooden ship, thinking determines the way out, and the load performance of components is designed and manufactured.

In order to improve the crack resistance of modules, Trina Solar has fully applied advanced non-destructive cutting technology. Compared with the traditional laser cutting process in the industry, the bending strength of the smallest battery cell is basically the same as that of the whole battery, that is, the flexural strength of each smallest cell The mechanical strength has reached the highest level, making the crack resistance of 600W+ ultra-high power modules a qualitative leap compared to conventional products in the industry.

In order to improve the bearing capacity of modules, Trina Solar has more than 20 years of photovoltaic research and development and technology accumulation. Through the dedicated research of the technical engineering team, Trina Solar has completed a series of design optimizations, increased the wall thickness of the frame, enlarged the cavity, and adopted high-strength aluminum alloys. The material ensures that the module has ultra-high structural strength; increasing the bolt spacer increases the effective area of contact between the bolt and the module, effectively improving the bearing capacity of the weakest connection point, making the 600W+ ultra-high power module have excellent load capacity.

Whole process quality control

600W+ leads comprehensive reliability

Photovoltaic module warranty commitment is 25 years. Trina Solar has been established for 25 years. It is the company that has been engaged in the photovoltaic module business for the longest time in the world. It has always been recognized by the industry as an "excellent student". Engraved into the genes of enterprise development, it is the bottom line and instinct.

From the front-end raw material control, Trina Solar has built a complete set of material assurance system, real-time monitoring of 32 key indicators and 992 material spc items of each batch of incoming materials, from supplier development, management, supervision, development In other aspects, the quality of supplier resources is fully guaranteed, and a reliable, consistent and safe material supply foundation is laid at the source.

To the reliable guarantee of the whole process of mass production, the quality team of Trina Solar improves product performance and quality in the closed-loop management mode of continuous cycle of prevention, discovery, correction and verification. The scope of reliability monitoring, including materials, batteries, components and some important changes, customer special requirements, covering major production bases around the world, covering all business areas. Continuous reliability test, including IEC 61215, IEC 61730, IEC 63216 and other series of standard full-sequence test items, most of the internal standards are 2-3 times stricter than IEC standards.

As for the informatization and intelligent management of production and manufacturing, as an industry leader, Trina Solar has built six 210 large-scale intelligent manufacturing bases around the world. , automation and intelligence, improve quality and efficiency through the operation of four modernizations, and deliver high-quality, high-value ultra-high-power products to customers.
