JA Solar 545W Photovoltaic Panel Technical Specifications

JA Solar 545W Photovoltaic Panel Technical Specifications

Core Electrical Parameters

This high-efficiency monocrystalline module delivers 545W output under standard test conditions (STC: 1000W/m², 25°C, AM1.5). Let's break down its electrical profile like reading a nutrition label for solar energy:

• Maximum Power Voltage (Vmp): 39.52V ±3%
• Open Circuit Voltage (Voc): 48.25V ±5%
• Short Circuit Current (Isc): 14.68A ±5%
• Module Efficiency: 21.3% (Think of it as the panel's "energy conversion GPA")

Physical Dimensions & Weight

Imagine stacking three large pizza boxes – that's roughly the panel's footprint optimized for rooftop installations:

• Dimensions: 2278mm × 1134mm × 35mm
• Frame Material: Anodized aluminum alloy (Weather-resistant like a seasoned sailor's gear)

Advanced Cell Technology

Using half-cut cell configuration, this module reduces resistance losses by 50% compared to traditional full-cell designs. The secret sauce? Laser cutting standard 156mm cells into 78mm segments, then connecting them in parallel – like creating multiple express lanes for electron traffic.

Temperature Performance

• Power Temperature Coefficient: -0.34%/°C (Maintains 92% output at 70°C)
• Operating Range: -40°C to +85°C (Survives Antarctic chills and desert heat)

Durability Certifications

This workhorse passes industry torture tests with flying colors:

• 5400Pa snow load rating (Equivalent to 2m of fresh snow)
• 2400Pa wind load resistance (Withstands Category 5 hurricane winds)
• PID resistance ≤2% (Prevents "solar panel arthritis" from potential-induced degradation)

Warranty & Longevity

Backed by JA Solar's 25-year linear power warranty – think of it as a retirement plan for your energy production:

• Year 1: ≤2% power degradation
• Annual degradation: ≤0.55% thereafter

For installers, the 545W rating hits the sweet spot between power density (350W/m²) and manageable module weight (28.5kg). The split junction box design allows flexible cabling configurations, adapting to complex roof layouts like a solar chameleon.
