Hanersun 445W Full Black Bifacial Solar Panel

The Hanersun HN18N-54HT-445 combines high-efficiency N-Type TOPCon technology, bifacial energy production, and a sleek full-black design. Rated at 445W from the front and up to 493W under BNPI bifacial test conditions, this module can produce additional power from sunlight reflected onto the rear of the panel.

With efficiency up to 22.8%, durable dual-glass construction, and an excellent -0.28%/°C temperature coefficient, this panel delivers dependable energy production in residential, commercial, rooftop, and ground-mount installations.

Increased Energy from Both Sides

Unlike standard monofacial panels, the Hanersun HN18N-54HT-445 can generate electricity from both the front and rear surfaces. Reflected sunlight from light-colored roofs, gravel, concrete, snow, or other reflective surfaces can increase total system production.

Actual bifacial gain depends on mounting height, tilt angle, ground reflectivity, row spacing, and site conditions.

Long-Term Performance & Warranty

Hanersun backs this module with a 25-year product warranty and a 30-year linear power output warranty. Guaranteed output begins at 99% during the first year, followed by no more than 0.4% annual degradation from years 2 through 30, resulting in at least 87.4% guaranteed output at year 30.
