xJA Solar 600W Bifacial N-Type Double Glass Solar Panel – JAM72D40-600/MB
The JA Solar JAM72D40-600/MB is a 600W bifacial N-type double glass solar panel for commercial rooftops, ground mount arrays and large-scale solar installations. Bifacial technology captures light from both the front and rear surfaces, increasing total energy yield on reflective surfaces such as light-coloured roofing membranes, concrete and open ground. The double glass construction replaces the conventional plastic backsheet with a second tempered glass layer for improved moisture resistance and long-term durability.
Key Features
- 600W rated output, 23.2% module efficiency
- N-type bifacial double glass construction
- Positive power tolerance: 0 to +3%
- Maximum system voltage: 1500V DC
- Voc 52.79V / Vmp 44.85V / Isc 14.04A / Imp 13.38A
- Dimensions: 2278 x 1134 x 30mm / Weight: 31.8kg
- Connectors: QC 4.10-351 or MC4-EVO2A
- 12-year product warranty / 30-year linear performance warranty
Product Overview
At 600W, each module generates more power per panel than standard 450W to 465W modules from a similar footprint. For a fixed roof area or ground mount this reduces the number of panels, mounting rails and labour cost per kW installed. The bifacial rear gain is highest on ground mounts and flat membrane roofs where reflected irradiance from below is consistent. On pitched roofs with dark tiles the rear gain is minimal.
N-type cell chemistry gives lower long-term degradation than P-type modules of comparable output. The albedo factor (the degree to which a surface reflects sunlight) determines how much rear-side energy gain is achievable at a given site.
Applications
- Commercial and industrial rooftop solar systems
- Ground-mounted solar arrays and solar farms
- Agricultural buildings and large barn roofs
- Flat roof installations with reflective membranes
What Is Included
- 1 x JA Solar JAM72D40-600/MB bifacial double glass panel
- Factory-fitted QC 4.10-351 or MC4-EVO2A connectors and cables
Installation Notes
At 31.8kg and 2278mm length, this panel requires two installers for safe handling. String voltage under cold conditions must be calculated against the inverter maximum DC input voltage. Maximum system voltage is 1500V DC. Installation must be carried out by a qualified MCS-accredited solar installer.
