Description

The Canadian Solar 540–555 W panel series (144-cell large-format) is a high-performance monocrystalline solar module engineered for modern rooftop and ground-mounted systems. With a large-format cell layout (typically 182 mm cells in 144-cell format) and advanced mono-PERC / half-cell technology, these modules deliver elevated power output, high efficiency and reliable long-term performance. Designed for both residential and commercial use where higher wattage per module translates into fewer panels, lower BOS (balance of system) cost and more efficient use of space.

Key Features:

⚡ High Rated Power (540 W-555 W): Modules in this series are rated around 530–555 W depending on variant, achieving high output per module. static.csisolar.com+2solartraders.com+2
🌞 Large-Format 144-Cell Layout: Uses 144 large-format monocrystalline cells for improved power density, reduced losses and better yield per square metre. jingsun-power.com+1
🔋 High Efficiency & Low Degradation: Efficiency up to ~21.5% (or higher depending on variant) and an advanced performance warranty (linear degradation <0.55% per annum) in many cases. static.csisolar.com+1

Applications:

✅ Residential rooftop solar systems – especially where high-output modules reduce number of panels and ease installation.
✅ Commercial rooftop or ground-mounted systems – where high power density per module allows more efficient use of space.
✅ Hybrid solar + storage systems – high wattage modules support larger generation capacity feeding into inverters/batteries.
✅ Installations in challenging climates – due to robust mechanical specs and wide temperature range.
