JA Solar 605W Bifacial Double Glass Solar Panel - JAM72D40 LB The JA Solar JAM72D40 LB 605W solar panel is a high-output bifacial double glass module designed for commercial, agricultural, off-grid and large residential installations. Built with advanced n-type cell technology, this panel offers strong efficiency, low annual degradation and the potential for additional rear-side generation where installation conditions allow reflected light to reach the back of the module. It is a robust, utility-grade panel suited to demanding environments and projects where long-term yield matters. Features High 605W rated outputWith a rated maximum power of 605W, this module is well suited to installations where maximising output per panel is important. It helps reduce the number of panels needed for a given system size and is ideal for larger roof and ground-mounted arrays. Bifacial energy generation The bifacial double glass design allows the module to generate power from both the front and rear sides. Under suitable installation conditions, rear-side gain can further improve overall energy yield, making it particularly attractive for ground-mounted systems and reflective surfaces. The datasheet includes performance figures based on 10% rear-side irradiation. Advanced n-type technologyThe JAM72D40 LB series uses n-type cells with MBB half-cell technology. JA Solar highlights benefits including lower LID, better low-light response and improved temperature behaviour, helping support strong real-world performance across a range of conditions. :contentReference[oaicite:3]{index=3} Excellent efficiency This 605W version achieves a module efficiency of 22.9%, giving high output from a panel measuring 2333 x 1134 x 30mm. This makes it a strong choice for customers seeking powerful modern panels from a widely recognised manufacturer. Durable double glass constructionWith 2.0mm front glass and 2.0mm rear glass, this module is designed for durability and long-term reliability. Double glass construction can offer advantages in environmental resistance and long service life, especially in more exposed installations. :contentReference[oaicite:5]{index=5} Strong warranty support JA Solar specifies a 12-year product warranty and a 30-year linear power output warranty for this series, reflecting its positioning as a premium long-life module. Suitable for commercial, agricultural and off-grid projects Designed for demanding installationsThe panel is rated for a maximum static load of 5400Pa on the front and 2400Pa on the rear, supporting use in challenging weather conditions. It also has a maximum system voltage of 1500V DC and an operating temperature range of -40°C to +85°C. :contentReference[oaicite:7]{index=7} Practical applications This module is a good fit for commercial rooftops, agricultural buildings, ground-mounted arrays, larger residential systems and off-grid energy projects where panel count, durability and long-term generation are all important. Its size and weight mean it is generally better suited to installations with adequate structure and handling arrangements. Dimensions are 2333 x 1134 x 30mm and weight is 32.5kg. :contentReference[oaicite:8]{index=8} Technical Specifications Manufacturer JA Solar Model JAM72D40-605/LB Rated Maximum Power (Pmax) 605W Module Efficiency 22.9% Open Circuit Voltage (Voc) 52.60V Maximum Power Voltage (Vmp) 43.94V Short Circuit Current (Isc) 14.53A Maximum Power Current (Imp) 13.77A Power Tolerance 0 to +3% Cell Type Mono, n-type bifacial Number of Cells 144 (6 x 24) Dimensions 2333 x 1134 x 30mm Weight 32.5kg Front / Back Glass 2.0mm / 2.0mm Connector QC 4.10-351 / MC4-EVO2A Cable Length Portrait: 300mm (+) / 400mm (-)Landscape: 1400mm (+) / 1400mm (-) Maximum System Voltage 1500V DC Operating Temperature -40°C to +85°C Maximum Series Fuse Rating 30A Maximum Static Load, Front 5400Pa Maximum Static Load, Rear 2400Pa NOCT 45 ±2°C Bifaciality 80% ±5% Product Warranty 12 years Linear Power Output Warranty 30 years All technical specifications above are taken from the JA Solar datasheet for the JAM72D40 LB series and the 605W variant. :contentReference[oaicite:9]{index=9} Support Documents Download JA Solar JAM72D40 LB 605W Datasheet
