Astronergy has officially unveiled ASTRO N7s 3.0, its latest flagship residential solar module, at the 2026 edition of Intersolar Europe, underlining the company’s ongoing commitment to advancing high-efficiency PV technologies for residential applications.
ASTRO N7s 3.0 adopts larger wafers, combined with half-cut cell and high-density encapsulation technologies, 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, the module integrates innovations including ASP, PF, SNOP, emitter passivation optimization and hydrogen passivation, improving passivation performance, light absorption and bifacial energy generation. Compared with 455W SMBB modules, it can generate an additional 440 kWh of green electricity annually.
Further optimization of ribbon connections strengthens the bond between ribbons and cells, contributing to greater long-term module reliability through encapsulation materials, which can fully fill overlapping areas.
Beyond performance, the module is also designed to meet the growing demand for aesthetically pleasing residential solar rooftops. Featuring an all-black appearance with 20BB design, aesthetic glass, black light-redirecting film (LRF-B) and no visible PAD points, it integrates seamlessly with modern rooftop architecture.
The ASTRO N7s 3.0 offers enhanced damp heat durability, improved corrosion resistance and verified salt mist protection, having also passed a 35 mm hail test and achieved a mechanical load capacity of +6000 Pa/-4000 Pa.
