Canadian Solar 355W BiKu Module Bifacial Solar Panels CS3U-355PB-AG

Description

Canadian Solar 355W BiKu Bifacial Solar Panel Dual-Glass CS3U-355PB-AG

Unlike traditional monofacial panels, the CS3U-355PB-AG can generate up to 30% additional energy from reflected light striking the rear side of the panel, making it an excellent choice for ground mounts, carports, and other projects where reflected light is available.

Backed by one of the industry’s most bankable manufacturers, this module delivers dependable performance with outstanding durability against harsh weather conditions.

Bifacial Technology Explained

Unlike conventional solar panels, bifacial modules collect sunlight from both sides of the panel.

The front produces the rated 355W, while the rear side can contribute additional power when mounted above reflective surfaces.

Estimated maximum output with rear-side gain:

Rear Side Gain	Effective Output
Standard Front Output	355W
5% Gain	373W
10% Gain	391W
20% Gain	426W
30% Gain	462W

Actual rear-side production depends on mounting height, surface reflectivity (albedo), spacing, and installation design.
