Model CS3W-450MB-AG | 144 Half-Cut Mono Cells | 20.1% Efficiency | 70% Bifaciality | 30-Year Warranty
The Canadian Solar CS3W-450MB-AG is a high-performance solar panel designed to maximize energy output with its bifacial technology. Featuring 144 mono-crystalline half-cut cells and 70% bifaciality, this innovative panel captures up to 30% more energy from the back side by utilizing reflected sunlight. With robust dual-glass construction and advanced technological features, it serves both residential and commercial needs effectively while ensuring long-term reliability.
Dual-Side Power Gain: Bifacial technology with 70% bifaciality captures up to 30% more energy from the back side, utilizing reflected sunlight to enhance efficiency even in less-than-ideal conditions.
Advanced 144 Half-Cell Design: Mono-crystalline cells arranged in a 144-half-cell format reduce internal resistance, boost performance, and provide better shading tolerance for higher energy yields.
Dual-Glass Construction: Two layers of 2.0mm heat-strengthened tempered glass protect against weathering while enhancing reflected light capture for improved overall efficiency.
Improved Temperature Coefficient: Low temperature coefficient of -0.34%/°C maintains performance even at higher temperatures for consistent energy production year-round.
Enhanced Durability: Anodized aluminum frame is built to withstand harsh weather conditions including heavy snow and high wind loads, ensuring long-term reliability.
Comprehensive Warranty: 12-year enhanced product warranty and 30-year linear power performance warranty ensures minimal degradation and sustained energy output over time.
