Callsun 450W Solar Panel 96 Cell N-Type Bifacial Dual Glass CS450-M2HD2608 Wholesale 36 Panels per Pallet

The Callsun CS450-M2HD2608 is a 450W N-type bifacial dual-glass solar module from Callsun's 440W-455W series, built for residential, commercial, and ground-mount installations. With 96 N-type monocrystalline cells and SMBB (super multi-busbar) technology, it delivers a module efficiency of 22.5%. This listing is the Silver Glass version.

Its double-glass construction captures sunlight on both sides, adding extra energy from reflected light. The module is ETL listed to UL 61215 and UL 61730, and is backed by a 20-year product warranty and a 30-year linear power warranty. Sold wholesale at 36 panels per pallet.

Bifacial Power Gain

The glass back lets the rear side produce extra power from reflected light. Under bifacial nameplate irradiance (BNPI: 1000 W/m² front, 135 W/m² rear), output rises to 498.6W. Callsun rates the rear side for up to 30% additional energy under favorable conditions. Actual gain depends on the mounting height and how reflective the ground surface is.

High Efficiency

N-type cells with SMBB technology improve current collection and reduce resistive losses, achieving 22.5% module efficiency and a rated 450W output under STC. A dual-layer front anti-reflective coating and an optimized rear-glass grid help the module capture and reflect more light.

Temperature Performance

With a Pmax temperature coefficient of -0.29%/°C, a Voc coefficient of -0.25%/°C, and an Isc coefficient of 0.045%/°C, the module keeps steady output in hot conditions. It operates from -40°F to 185°F (-40°C to 85°C).

Quality and Reliability

The module is certified to UL 61215, UL 61730, and CSA C22.2 No. 61730 (Intertek ETL), as well as IEC 61215 and IEC 61730. Callsun manufactures under ISO 9001, ISO 14001, and ISO 45001 management systems. The module carries a Type 29 fire rating, is Class II for safety, and is built to resist potential-induced degradation (PID) in hot and humid environments.

Long-Term Power Warranty

The module is backed by a 20-year product warranty and a 30-year linear power warranty. Degradation is limited to 1% in the first year and 0.4% per year after that, with at least 87.4% of rated power guaranteed at year 30.

Durable Double-Glass Construction

Both faces use 2.0mm (0.08 in) glass: the front has an anti-reflective coating, and the back is heat-strengthened. The cells are held in a 30mm (1.18 in) anodized aluminum frame. The IP68 junction box with 3 bypass diodes protects against dust and water and reduces power loss from partial shading.
