Canadian Solar HiKu CS3W-MS High-Power Mono PERC Module (445 W)

The HiKu CS3W-MS by Canadian Solar is engineered for high performance, durability, and long-term return on investment. With its high efficiency and power output, it’s ideal for large commercial arrays, utility-scale installations, and premium residential systems.

Thanks to its robust mechanical design, it is capable of handling extreme weather conditions and heavy loads. High tolerance for mechanical stress and superior shading resilience also help reduce losses from micro-cracks or partial shading scenarios.

Canadian Solar backs the module with strong warranties, ensuring long-term performance reliability giving customers confidence in their solar investment.

• High Power Output — Delivers between 435 W and 465 W under Standard Test Conditions. 

• Premium Efficiency — Module efficiency up to 21.0 % (depending on variant) for maximum yield. 

• Superior Warranty & Performance — 12-year product warranty and long-term linear power warranty (≤ 2 % degradation in year 1, ≤ 0.55 % per year thereafter). 

• Robust & Reliable Design — Withstands up to 5,400 Pa snow load and 3,600 Pa wind load, featuring anti-reflection glass and an anodized aluminum frame. 

• Low Thermal Losses — Nominal Module Operating Temperature (NMOT) at 41 ± 3 °C; low temperature coefficient helps maintain output in heat.

• Wide Voltage Compatibility — Designed for 1,000 V or 1,500 V systems (depending on certification) for flexibility in system design.
