Astronergy ASTRO N7s 450W N‑Type Bifacial All‑Black Solar Panel

Model: CHSM48RN(DG)(BLH)/F‑BH‑450 | 450W all‑black, N‑type TOPCon bifacial dual‑glass solar panel module with ZBB zero‑busbar cell technology, high efficiency and 30‑year performance warranty.

Bifacial All‑Black Solar Panel Key Features

• High‑output 450W N‑type monocrystalline TOPCon module with up to 22.5% module efficiency.
• Bifacial, dual‑glass design for additional rear‑side yield and enhanced durability.
• All‑black aesthetics: black cells, black frame and dark rear appearance for premium rooftops.
• Zero‑busbar (ZBB) cell interconnection for a deeper black look, reduced silver use and higher reliability.
• Tiling‑film layout to minimise cell gaps and micro‑crack risk, improving long‑term performance.
• Outstanding warranty package: long product warranty (often 25 years) and 30‑year linear performance guarantee.
