HanerSun 445W HItouch5N Bifacial N-TOPCon HN18N-54HT445W

Tier 1 Bloomberg NEF Panel

The Hanersun HN18N-54HT445W is a high-efficiency bifacial solar module built on N-type TOPCon cell technology. Designed for residential, commercial, and light utility applications, this module delivers strong front-side output with additional rear-side energy gain while maintaining low degradation and excellent long-term reliability.

Hanersun is recognized as a Tier 1 PV module manufacturer by BloombergNEF (BNEF), making this panel suitable for bankable solar projects.

Module Overview

This HiTouch5N series module uses 182 mm N-type monocrystalline cells in a half-cell, multi-busbar layout to improve current collection and reduce resistive losses. The bifacial glass-on-glass construction allows the rear of the module to capture reflected irradiance, increasing total system yield depending on site albedo and mounting configuration.
