Chinese PV module maker Astronergy, a unit of the Chint Group, has unveiled its new Astro N8 Pro series at SNEC 2026 in Shanghai last week.
The new series includes two formats. The CHSM72N version offers a power output of 800 W to 825 W, with module efficiency of up to 24.4%. The CHSM66N version is rated at 740 W to 760 W, with a maximum efficiency of 24.5%. The modules measure 2,595 mm × 1,303 mm × 33 mm and 2,384 mm × 1,303 mm × 33 mm, respectively.
Astronergy said the Astro N8 Pro series is based on its TOPCon 5.0+ technology platform and incorporates 210 mm wafers, quarter-cut cells, high-density encapsulation, and multi-busbar technology. According to the company, the design is intended to increase module power while reducing hot-spot risk, improving reliability, and lowering balance-of-system costs for utility-scale and distributed PV projects.
According to the company’s product information, the modules have a bifaciality factor of around 85% and a power temperature coefficient of -0.26%/C. The series supports system voltages of up to 1,500 V DC and offers a positive power tolerance of 0 W to 3 W. Astronergy said the product is designed for high-output applications where land use, string design, and lifetime energy yield are key considerations.
The company also highlighted the series’ long-term performance. The Astro N8 Pro modules are backed by a 15-year product warranty and a 30-year linear power warranty. First-year degradation is specified at no more than 1%, followed by annual degradation of no more than 0.35% from the second through the 30th year.
The 72-cell-format version features an anti-dust frame design aimed at applications where soiling losses and cleaning costs can affect project economics. Astronergy said the design is intended to reduce power losses caused by dust accumulation and deliver additional energy generation gains of around 2% to 6%, depending on site conditions.
Astronergy President Lu Chuan said the Astro N8 Pro series reflects the company’s long-term development of n-type technology and system-level optimization.
At SNEC 2026, the company also showcased the Astro N8, a 745 W module for utility-scale solar projects; the Astro N7 Pro, based on TOPCon 5.0+ technology and a quarter-cut cell design; and upgraded Astro N7 3.0 and Astro N7s 3.0 products for differentiated applications.
