Astronergy's ASTRO N7 66-cell product redefines solar efficiency standards

In an ever-evolving solar industry, Astronergy, a global leader, is once again setting the bar high with its latest innovation, the ASTRO N7 66-cell product series. Unveiled at the SNEC Shanghai event on May 24, 2023, this new addition is a strategic response to the escalating market demands for more efficient and powerful solutions.

The ASTRO N7 66-cell product emerges as an extension of the heralded ASTRO N7 series, catering to an evolving market seeking enhanced performance. Using rectangular PV cells measuring 182mm*210mm, these cells boast a remarkable 15.6%+ increase in area compared to the conventional M10 182 silicon wafer cells, marking a significant stride in energy capture and utilization.

At the heart of this technological leap is the innovative TOPCon 3.0, a cornerstone in Astronergy’s advancements. With an average efficiency rating of 25.7%+, the n-type TOPCon PV cell technology stands as a testament to Astronergy’s independent research and development prowess.

Notably, the incorporation of Boron-LDSE cell technology within the TOPCon 3.0 framework promises not just increased module power and efficiency but also a notable reduction in the cost per watt, reflecting a strategic alignment of performance and economic feasibility in their product range.

Main features

The ASTRO N7 66-cell product, tailored for utility scale solar systems, introduces a paradigm shift in solar panel technology with its latest features. Starting with a Higher Power Out, over 615W. This, coupled with an efficiency rating surpassing 22.8%, ensures higher energy yields and heightened reliability.

What distinguishes the ASTRO N7 66-cell is its manufacturing innovation leveraging SMBB (cell processing technology), incorporating more busbars on cells to evenly distribute stress through additional weld joints in the main grid line. This reduces silver paste loss, series resistance, and cell power loss, improving module efficiency. Moreover, the design reinforces resilience against hidden cracks and broken grids, ensuring prolonged and dependable performance.

Beyond its power prowess, the ASTRO N7 66-cell integrates features for optimized performance and cost-efficiency. Its high-transmittance glass, light redirecting film (LRF), and a lower temperature coefficient (-0.29%) contribute to higher power output per watt. Additionally, its low voltage characteristics enable streamlined system designs, reducing both Balance of System (BOS) and Levelized Cost of Electricity (LCOE) costs for consumers.

Complementing these features are other attributes. The first one is a Better Low-irradiation Performance. Verified by UL, the modules exhibit exceptional low-irradiation performance, maintaining 97.8% efficiency at 200W/?, outperforming PERC products by over 1%. This ensures consistent power generation, even in in cloudy weather with low irradiance.

Moreover, the ASTRO N7 showcases low Light-Induced Degradation (LID) and Low Effective Temperature-Induced Degradation (LETID). Its ability to operate at a lower temperature than traditional PERC modules, approximately 1.6? lower on average, offers theoretical power generation gains.

With these groundbreaking features, the ASTRO N7 66-cell product establishes a new benchmark for utility scale solar systems. Its excellent product quality ensures that after 30 years of steady output, the power will not be less than 87.4%.

Finally, with an annual degradation of -0.4% between the 2nd year and up to 30 years, the ASTRO N7 66-cell product promises improved efficiency, reliability, and cost-effectiveness, along with adaptability to various environmental conditions, reshaping the landscape of solar energy production.
