Product description:

For global PV plant developers, EPC contractors, commercial/industrial property owners and overseas PV project investors, this TOPCON monocrystalline bifacial dual-glass module (620W-650W) is a high-power, high-efficiency core power generation component positioned for large-scale utility solar farms, commercial & industrial distributed PV projects and international PV infrastructure projects, integrating high yield, extreme durability and system-wide cost optimization.

Core Selling Points:

✅ Versatile Scenario Adaptability:

Boasting 1500V DC system voltage, MC4-compatible connectors and a 2382×1134×30mm compact design, it seamlessly fits centralized ground PV power stations, commercial building rooftops, PV carports and overseas PV infrastructure projects. Its 37 units/box and 740 units/40’container packaging optimizes logistics for large-scale deployment across diverse application scenarios.

✅ Stable High-Quality Power Generation:

Boasting 620W-650W output, a market-leading 24.06% max efficiency and 0~+3% power tolerance, the 132 [6×22] 182*105mm cell design with optimized series-parallel connection delivers consistent high power for commercial rooftop and utility farm baseload generation; a -0.28%/℃ Pmax temperature coefficient and 44±2℃ NOCT ensure minimal efficiency loss under real-world operating temperatures, sustaining high energy production for commercial and utility PV systems.

✅ Durability in Extreme Environmental Conditions:

Constructed with 2.0mm anti-reflection front glass + 2.0mm high-transparency back glass and an alloy steel frame, the IP68-rated module withstands 2400Pa wind/5400Pa snow loads—ideal for open-air utility farms and outdoor PV carports in high-wind/snow regions; operable at -40~+85℃ and certified to IEC 61701/62716 (salt mist, ammonia corrosion, sand blowing, PID), it maintains performance in coastal industrial zones, arid PV farm sites and corrosive commercial industrial environments.

✅ Guaranteed Long-Term Reliable Performance:

Backed by reinsurance coverage and a 30-year linear performance warranty (99% output in Year 1, 87.40% in Year 30), the module undergoes 2×100% EL inspection for defect-free production and ISO9001:2015 quality control—aligning with the 25+ year lifespan of commercial and utility PV assets; Fire Class C protection via double glazing and 3 built-in diodes prevent fire and power loss risks, ensuring safe, uninterrupted operation for commercial rooftop systems and utility-scale solar farms.
