The Hanersun HN18N-54HT is a 440W bifacial monocrystalline solar panel with dual-glass construction and roughly 22.3% module efficiency. Its rear face captures reflected light, so it can add output on ground mounts, flat roofs and bright reflective surfaces where a monofacial panel cannot. It carries a 15-year product warranty and a 30-year performance warranty to 80% output, which is competitive with Tier-1 rivals. It suits homeowners and installers planning ground-mount or open-rack arrays; on a tightly packed pitched roof, the bifacial gain is largely wasted.

Owner and installer feedback on Hanersun's bifacial glass-glass modules is generally positive on build quality and output, with the usual caveats about real-world bifacial gain and weight.
The Hanersun 440W Residential Solar Panel (HN18N-54HT) is a Tier-1, bifacial monocrystalline solar module for residential and commercial installations. It has a rated power output of 440W and 108 cells. Module efficiency is listed as 22.3%, and up to 22.8% is also stated.
The panel uses dual-glass construction with a 2.0mm anti-reflection coated back glass and a 2.0mm AR coated semi-tempered front glass. The frame is anodized aluminum alloy. The design lowers the risk of hot spots and cracks compared with standard modules.
The bifacial design captures sunlight from both the front and rear surfaces, including light reflected from the ground, roof or other surfaces. This suits ground-mount systems, flat roofs and highly reflective surfaces. Energy gains of 5-15% over comparable monofacial modules are possible in the right installation.
