ASTRONERGY ASTRO N7s CHSM-48RN(DG)/F-BH 460W Bifacial All Black n Solar Panel

• High-efficiency 460W bifacial n-type TOPCon 4.0 module with up to 23.0% module efficiency for compact commercial and industrial arrays.
• Dual-glass construction and 6000Pa / 4000Pa test loads for robust performance on exposed roofs and ground-mount structures.
• Long-term reliability backed by 25-year product warranty and 30-year linear power warranty.

Overview

The ASTRO N7s CHSM-48RN(DG)/F-BH 460W is a bifacial, dual-glass n-type TOPCon solar panel designed for modern rooftop and ground-mounted systems where space, durability and output per square metre matter. With 460W STC output, 23.0% module efficiency and bifaciality of 80±5%, it is well suited to commercial, industrial and logistics sites looking to maximise yield on limited roof or frame area.

Key features

• 460W bifacial module with 23.0% maximum efficiency and positive power tolerance of 0~+3%.
• n-type TOPCon 4.0 cells with ZBB (zero-busbar) design for high performance and low degradation (≤1.0% first year, ≤0.4% per year years 2–30).
• Glass-glass build (2.0mm front + 2.0mm back) with aluminium frame and IP68 junction box for harsh environments.
• Compact footprint under 2m² (1762 × 1134 × 30mm) and 24.5kg weight for easier handling and installation.
• Certified to IEC 61215 and IEC 61730, manufactured under ISO 9001, ISO 14001 and ISO 45001 quality systems.

Where to use

This ASTRO N7s 460W bifacial panel is ideal for commercial roofs, logistics hubs, agricultural buildings and industrial sites where you want high output from relatively small arrays. The bifacial design is particularly effective on light-coloured roofs, elevated frames, carports and ground-mount systems with good rear-side irradiance.

For UK and European projects, Energian can support system design and supply, with installation carried out by trusted partners experienced in dual-glass bifacial modules and C&I mounting systems. This panel integrates well with modern string inverters and mounting solutions for on-grid, hybrid and commercial self-consumption systems.
