Zhengtai Xinneng Heavily Releases ASTRO N7 Series Components

On May 24th, at the 16th (2023) International Solar Photovoltaics and Smart Energy Conference of SNEC, Chint New Energy launched a new n-type TOPCon module product - the ASTRO N7 series.

At the SNEC exhibition, the Chint Xinneng booth was very popular

In April 2022, Chint Xinneng launched the ASTRO N series component product, which has already caused a sensation in the industry. The ASTRO N7 series released this time is another masterpiece of Chint Shineng in the n-type era.

It is understood that the ASTRO N7 series continues all the advantages of the Chint Xinneng ASTRO N series and is fully upgraded on the basis of its original performance.

In terms of silicon wafers, the ASTRO N7 series adopts 182mm * 191mm size silicon wafers, which increases the area by 5% and the single chip power by 7.6% compared to the traditional size 182 silicon wafers;

In terms of batteries, the ASTRO N7 series adopts Chint New Energy TOPCon3.0 battery technology, with an average production efficiency of 25.6%. The average conversion efficiency of the R&D pilot line has reached 26.0%, and the addition of SMBB technology effectively reduces silver consumption and increases the tolerance of cracking by 50%;

In terms of packaging technology, the ASTRO N7 series uses gap reflective film throughout the entire series, effectively improving light transmittance and component power, while ensuring double-sided efficiency and reliability of the components.

With the support of multiple technological innovations, the ASTRO N7 series can effectively reduce transportation costs, increase component lifecycle power generation, reduce system costs, and ultimately achieve a reduction in electricity costs.

According to the Chint New Energy Plan, the ASTRO N7 series will achieve mass production in the third quarter of this year, with a production capacity of 4GW by the end of the year and over 15GW by 2025.

Weike Network Photovoltaics immediately interviewed Mr. Zhou Shengyong, General Manager of Global Product Technology Services of Chint Xinneng, to share the advantages of the ASTRO N7 series and the forward-looking layout of Chint Xinneng in the n-type era.

What are the improvements in performance and efficiency of the ASTRO N7 series launched this time?

Zhou Shengyong: The overall improvement in performance and efficiency of the ASTRO N7 series can be summarized as "four highs and one low".

Firstly, it is high power. The ASTRO N7 72 edition double-sided double glass module has a power of 615W, enriching the product line of Chint Shineng at 600W+.

The second is high component efficiency. Zhengtai Xinneng is the earliest enterprise in the industry to introduce technologies such as LDSE batteries and passivation of the back glass layer, effectively improving battery efficiency.

The third is high reliability. The ASTRO N7 series introduces technologies such as SMBB and gap reflective film, further improving reliability.

The fourth is high single watt power generation. The ASTRO N7 series has excellent temperature coefficient, higher double-sided rate, and can increase single watt power generation by 3% -5% compared to mainstream PERC components.

Finally, the lower system and kilowatt hour cost fully reflects the efficiency of the ASTRO N7 series.

Weike Network Photovoltaics: Recently, the efficiency of TOPCon batteries has improved rapidly. What do you think the final mass production efficiency of TOPCon batteries will reach? How will Chint maintain its leading advantage in efficiency?

Zhou Shengyong: Zhengtai Xinneng released n-type components globally in April 2022. In July of the same year, it began mass production of the first TOPCon battery and components. It has accumulated rich experience in mass production and has also accumulated many advanced technologies in research and development. The theoretical efficiency of TOPCon batteries can reach 28.7%, and there is still nearly 3% room for improvement.

There is still great potential for us to improve battery efficiency in the future, including the LDSE technology and back passivation technology mentioned earlier. I believe that by the end of this year, the production efficiency of Chint Shineng's TOPCon batteries can reach a level of 25.6%. There is still a lot of room to explore in the future and continue to maintain Chint Shineng's leading advantage in the industry.
