About This Product
The JA Solar JAM72-D40-595MB 595W Bifacial Solar Panel is a high-output monocrystalline solar module designed for commercial, industrial, and larger residential solar installations. Part of JA Solar’s JAM72-D40 series, this panel uses bifacial technology to generate electricity from direct sunlight on the front and reflected light reaching the rear of the module.
The panel features a silver aluminum frame, transparent rear construction, and factory-fitted MC4-EVO2 connectors. Its 1500V DC maximum system voltage rating supports appropriately engineered commercial solar arrays, while its bifacial design offers additional energy-generation potential where installation conditions allow rear-side light exposure.
JA Solar backs this module with a 12-year manufacturer product warranty and a 30-year linear performance warranty, providing documented long-term performance coverage for professionally installed solar systems.
Who This Product Suits
The JA Solar JAM72-D40-595MB is suited to solar installers, electrical contractors, and commercial project developers looking for a high-wattage bifacial module for grid-connected photovoltaic systems.
- Commercial and industrial rooftops: Suitable for projects requiring substantial DC generating capacity with fewer modules per installed kilowatt.
- Ground-mounted solar arrays: Bifacial construction can capture reflected sunlight from the ground, particularly where suitable surface reflectivity and mounting clearance are provided.
- Large residential installations: An option for properties with sufficient roof space and compatible mounting and electrical equipment.
- Commercial solar expansion projects: Suitable for new array sections where electrical characteristics, string design, and equipment compatibility have been verified.
Installers should confirm inverter compatibility, structural loading, mounting requirements, connector compatibility, and applicable NEC requirements before specifying this module.
Specifications Explained
- 595W Rated Output: The module’s front-side power rating under Standard Test Conditions (STC), used for solar array sizing and equipment selection.
- Bifacial Monocrystalline Technology: Generates electricity from sunlight reaching both sides of the module. Actual rear-side energy contribution depends on mounting configuration, ground reflectivity, shading, and site conditions.
- 132-Cell Configuration: The supplier-listed cell configuration identifies the module’s internal solar cell arrangement.
- 1500V DC Maximum System Voltage: Supports appropriately designed high-voltage PV strings, subject to equipment ratings, temperature-corrected voltage calculations, and NEC requirements.
- Silver Frame and Transparent Rear Construction: Provides a framed module design that allows reflected light to reach the rear solar cells.
- Factory-Fitted MC4-EVO2 Connectors: Provides standard PV cable connection hardware. Installers must use manufacturer-approved mating connectors and follow applicable electrical installation requirements.
- 12-Year Product Warranty: Manufacturer coverage for qualifying product defects, subject to JA Solar’s warranty terms.
- 30-Year Linear Performance Warranty: Specifies 1% first-year degradation followed by 0.40% annual degradation, subject to the manufacturer’s published warranty conditions.
System designers should verify the module’s electrical operating characteristics against the official JA Solar datasheet when calculating string voltages, operating currents, and inverter compatibility.
