JA Solar JAM72-D40 600W Bifacial Solar Panel

About This Product

The JA Solar JAM72-D40 600W Bifacial Solar Panel is a high-power bifacial monocrystalline module designed for commercial, utility-scale, and larger residential solar installations. This D40-series module is rated at 600W and uses a 132-cell configuration with a silver frame and transparent backsheet, allowing the rear side of the module to contribute additional energy when suitable reflected light is available. It is designed for 1500V DC PV systems and is supplied with 1300 mm cables and genuine MC4-compatible factory connectors for professional system integration.

Who This Product Suits

The JA Solar JAM72-D40 600W module suits installers and system designers who need high wattage per module for commercial rooftops, ground-mount arrays, and other projects where reducing the number of modules required for a given DC array size can be useful. Its bifacial construction is particularly relevant to installations where the rear of the module receives usable reflected or indirect sunlight. System designers should verify string voltage, inverter compatibility, mounting configuration, conductor sizing, and applicable NEC requirements before installation.

Specifications Explained

• 600W rated output: Provides a high nameplate power rating per module, making it well suited to larger PV arrays.
• Bifacial monocrystalline design: Generates power from the front surface and can also produce additional energy from light reaching the rear side under suitable installation conditions.
• 132-cell configuration: Uses JA Solar’s large-format module architecture for high-output PV applications.
• 1500V maximum system voltage: Supports system designs operating up to the module’s specified 1500V DC limit, subject to inverter, equipment, NEC, and local code requirements.
• Transparent backsheet: Allows light to reach the rear-facing active surface for bifacial energy production.
• Factory leads and connectors: Supplied with 1300 mm cables and MC4 connectors for integration into compatible PV wiring systems.
• Warranty coverage: Backed by a 12-year manufacturer product warranty and a 30-year linear performance warranty, with stated degradation of 1% in the first year followed by 0.40% annually.

Summary

The JA Solar JAM72-D40 600W is a high-output bifacial module intended for professionally designed PV systems. Its 600W rating, bifacial monocrystalline construction, transparent backsheet, 1500V system capability, and factory MC4 connections make it a practical option for installers building larger residential, commercial, or ground-mounted arrays. As with any high-power module, final string configuration and equipment compatibility should be confirmed during system design.
