Product Overview
The JA Solar JAM72D40-610/LB is a 610W n-type double glass bifacial solar module designed for high-output solar PV systems. With mono cells, bifacial generation capability and a durable dual-glass construction, it is suitable for residential, commercial, agricultural and larger-scale solar installations where strong energy yield and long-term reliability are important.
Key Features
- 610W rated maximum power output for high-capacity solar installations.
- n-type double glass bifacial module design allows additional rear-side generation when installed in suitable reflective conditions.
- 23.1% module efficiency helps maximise available roof or mounting space.
- Positive power tolerance of 0~+3% provides confidence that the module output will not be below its stated rating under STC.
- Low first-year degradation of 1% and 0.4% annual degradation over 30 years, as stated in the datasheet.
- 1500V DC maximum system voltage supports use in modern PV array designs.
- Dual 2.0mm front and back glass construction supports long-term durability in outdoor solar installations.
Applications
- Grid-tied and hybrid solar PV systems.
- Commercial and industrial rooftop solar installations.
- Ground-mount solar projects and larger PV arrays.
- Residential solar systems where the roof area, inverter and string design are suitable for large-format modules.
- Bifacial installations where rear-side irradiance can be used effectively.
Why Choose This Product?
This JA Solar 610W module is a practical option for installers and system owners looking for a high-power solar panel with bifacial energy-gain potential, n-type cell technology and a long linear power output warranty. Its strong efficiency, positive power tolerance and double glass design make it well suited to reliable long-term PV performance.
Important Notes
- Solar panel compatibility must be confirmed against the inverter, MPPT voltage range, string design and installation conditions before purchase or installation.
- Bifacial gain depends on installation height, rear-side exposure, surface reflectivity and shading conditions.
- Installation should be carried out by a qualified solar installer or electrician in line with applicable South African electrical and PV regulations.
- For Nextracker installations, the datasheet notes that maximum static load requires a compatibility approval letter between JA Solar and Nextracker.
- Customised frame colour and cable length are noted by the manufacturer as available upon request.
