Astronergy officially unveiled ASTRO N7s 3.0, its latest flagship residential solar module, for the first time globally at Intersolar Europe 2026, demonstrating the company’s continued commitment to advancing high-efficiency photovoltaic technologies for residential applications.

ASTRO N7s 3.0 adopts larger wafers, combined with half-cut cell technology and high-density encapsulation technology, to maximize utilization of the cell spacing area, increase the active area and further enhance power generation efficiency.

Built on Astronergy’s latest TOPCon 5.0 cell technology, ASTRO N7s 3.0 integrates innovations, including ASP, PF, SNOP, emitter passivation optimization, and hydrogen passivation. Together, these advancements help improve passivation performance, light absorption, and bifacial energy generation. Compared with 455W SMBB modules, ASTRO N7s 3.0 can generate an extra 440 kWh of green electricity annually, which is enough to power the operation of home appliances each month, such as 9 loads of laundry, 17 dishwasher cycles, and 73 hours of TV time. 

With a high-density, low-stress flexible interconnection technology, ASTRO N7s 3.0 creates a seamless design with a larger active area, leading to improved current collection capability and higher energy output. At the same time, this technology also ensures a more uniform stress distribution and reduces the risk of hidden cracks significantly. 

Further optimization of ribbon connections strengthens the bond between ribbons and cells by enabling encapsulation materials to fully fill overlapping areas. This design can reduce the risk of ribbon detachment or breakage caused by thermal cycling (TC), contributing to greater long-term module reliability.

Beyond performance, ASTRO N7s 3.0 is also designed to meet the growing demand for aesthetically pleasing residential solar rooftops. Featuring an all-black appearance with its 20BB design, aesthetic glass, black light-redirecting film (LRF-B), and no visible PAD points, ASTRO N7s 3.0 integrates seamlessly with modern rooftop architecture.

The module also brings practical advantages during installation. Thanks to its lightweight and compact design, ASTRO N7s 3.0 supports single-person transportation and installation, making it highly adaptable to residential rooftops where installation space may be limited.

While optimizing installation convenience and visual appeal, Astronergy has also ensured that ASTRO N7s 3.0 provides reliable performance in challenging operating environments.

The module offers enhanced damp heat durability, improved corrosion resistance, and verified salt mist protection. Its mechanical robustness is further demonstrated by passing a 35 mm hail test and achieving a mechanical load capacity of +6000 Pa/-4000 Pa. 

Backed by a 25-year product warranty and a 30-year linear power warranty, ASTRO N7s 3.0 limits first-year degradation to ≤1% and annual degradation to ≤0.4% thereafter, ensuring long-term energy yield. 

Aligned with Astronergy’s sustainability strategy, ASTRO N7s 3.0 is manufactured using a low-temperature manufacturing process that reduces energy consumption, eliminates flux usage, and achieves zero VOC emissions, resulting in a lower-carbon footprint and contributing to
