Factory-packed pallet of 36 JA Solar JAM72D40-600/MB bifacial N-type double glass solar panels, giving a total pallet capacity of 21.6kW. Each panel is rated at 600W with 22.7% module efficiency, built from N-type monocrystalline half-cut MBB cells between two sheets of tempered glass. The 26% figure sometimes seen in marketing material refers to individual cell efficiency, not the module efficiency, which is 22.7% for this panel.

Key features

• Output, 600W per panel, 21.6kW per pallet of 36
• Cell technology, N-type monocrystalline half-cut MBB cells
• Bifacial gain, up to 20% additional rear-side energy depending on installation conditions
• Glass, dual 2.0mm tempered front and rear
• Power tolerance, 0 to +3%
• Degradation, 1% in year one, then 0.4% annually over 30 years

Dimensions are 2333 x 1134 x 30mm and each panel weighs 32.5kg. Operating temperature range is -40°C to +85°C. The panels are certified to IEC 61215 and IEC 61730, and manufactured under ISO 9001, ISO 14001 and ISO 45001. Cover comes as a 12-year product warranty with a 30-year linear performance warranty.

Half-cut cell and dual glass construction

The half-cut MBB cell layout lowers internal resistance and improves shade tolerance against full-cell modules, so if one half of the panel is partially shaded the other half keeps generating at full output. The dual glass build suits high-humidity or coastal sites, and agricultural buildings where chemical exposure can degrade plastic-backsheet panels over time.

Applications

Suited to commercial and industrial rooftops, ground-mounted arrays and solar farms, agricultural buildings, flat roof systems with reflective membranes, and trade or installer purchases for larger projects.

What's in the box

• 36 x JA Solar JAM72D40-600/MB bifacial double glass panels
• Factory-fitted connectors and cables per panel
• Pallet packaging, each panel with a unique serial number

Installation notes

At 32.5kg and 2333mm in length, each panel needs two installers for safe handling. String voltage should be calculated for cold conditions, with a maximum system voltage of 1500V DC. Supplied on pallet delivery only, and installation must be carried out by a qualified MCS-accredited solar installer.
