Astronergy’s ASTRO N7 Pro is rated at up to 670 W, with reported module efficiency reaching 24.8%
The module is based on the company’s so-called TOPCon 5.0+ cell technology and introduces a quarter-cut cell layout to reduce current losses and hotspot temperatures
The series targets improved performance under shading, low-irradiance, and high-temperature operating conditions
China-based solar manufacturer Astronergy has launched its ASTRO N7 Pro series of high-efficiency PV modules for utility-scale and commercial & industrial (C&I) solar applications. According to the CHINT Group company, the ASTRO N7 Pro series is rated at up to 670 W of power output, with a reported module efficiency of 24.8%.
The ASTRO N7 Pro platform is based on Astronergy’s upgraded n-type TOPCon solar cell technology, which the company calls TOPCon 5.0+. The company states that the platform incorporates cell-level process improvements, characterized as proprietary abbreviations ASP, PF, and SNOP. However, the press release does not divulge much on these processes.
A key structural change in this generation is the adoption of a quarter-cut cell design. According to the company, this lowers internal operating current at the cell level and reduces associated resistive power losses. It adds that this layout helps reduce peak hotspot temperatures and supports more uniform current distribution across the module.
Under partial shading scenarios, Astronergy reported that the ASTRO N7 Pro modules demonstrate improved output retention. The company attributed this to an optimized circuit design, stating that the module can achieve higher power output than conventional half-cut cell modules under shading.
The ASTRO N7 Pro series is also designed for operation in low-irradiance and high-temperature environments. Astronergy cited improvements in shunt resistance (Rsh) and reduced current leakage paths as contributing to higher single-watt energy yield. The module has a reported temperature coefficient of -0.26%/°C, supporting more stable power generation in regions with elevated operating temperatures.
Astronergy claims a bifaciality of up to 85±5% for the ASTRO N7 Pro modules. The company attributed reliability improvements to the quarter-cut cell layout, a 20-busbar (20BB) design, and a low-temperature, low-stress manufacturing process without flux.
The ASTRO N7 Pro series is backed by a 15-year product warranty and a 30-year linear power output warranty.
Astronergy’s commercially available module is featured in the TaiyangNews TOP SOLAR MODULES listing, where it secured the 5th rank in the December 2025 edition. The TOPCon module from the ASTRO N7 series reaches an efficiency of 23.51% with a rated power output of 635 W. Owing to its sustained presence in the top 10 rankings throughout the calendar year, Astronergy also earned the TaiyangNews Badge of Excellence 2025 (see TOP SOLAR MODULES 2025: Badge Of Excellence). While the qualification criterion requires companies to feature in the top 10 for at least 6 months of a year, Astronergy maintained its position within this group throughout the year.
TaiyangNews is bringing together the Indian solar PV manufacturing industry for the Solar Technology Conference India 2026 (STC.I 2026). To be held on February 5 and 6 in Aerocity, New Delhi, this 2nd edition of the TaiyangNews physical conference will also have banks, investors, and policymakers in attendance.
